Taxonomy and phylogeny of dematiaceous coelomycetes

Eric McKenzie

Over the years, there have been continuous updates in the taxonomy of coelomycetes. In particular, traditional classification has been revised and updated based on extensive collections supplemented with morphological examinations and phylogenetic analyses. Most of the data available are scattered in the literature. In an attempt to ease the work of mycologists and bring all these data together, a website has been created, available at https://www.coelomycetes.org. Information provided on the webpage is in line with the current ranking and classification of taxa and will include photoplates, drawings, phylogenetic trees, notes and descriptions.

Five asexually reproducing basidiomycetous fungi, isolated from northern and southern provinces of Thailand, characterized by slimy, setulate conidia in creamy white pycnidia and classified in the genus Chaetospermum, are studied in detail. Two species, C. camelliae and C. artocarpi, are redescribed and epitypified. A phylogenetic tree based on 28S large subunit rDNA (LSU) sequence was used to analyze their taxonomy and relationships. The study confirmed that Chaetospermum belongs to the Sebacinales, a poorly studied order of Agaricomycetes.

Coelomycetes comprise about, 1000 genera and 7000 species, which can be endophytic, pathogenic or saprobic. Traditional classification of coelomycetes was previously based on morphology, such as the shape of conidiomata and mode of conidiogenesis, while it was treated as a distinct group i.e. Deuteromycotina. Sequence based taxonomic studies has been used to accommodate asexual fungi in a natural classification system, resolve generic boundaries of polyphyletic genera and species complexes, as well as establish asexual-sexual links. Nevertheless, most of genera lack sequence data, thus, morphology based identification is still important when introducing new genera or species. In this paper we illustrate, describe, and provide taxonomic notes for 235 dematiaceous coelomycetous genera, including five new genera viz. Apiculospora, Didymellocamarosporium, Melanocamarosporium, Melnikia and Paulkirkia.

One-hundred and fifty-two (65 %) of genera have sequence data, thus, their taxonomic placement in a natural classification system, is listed as an outline. However, 83 genera still lack sequence data, hence, they are treated as Ascomycota, genera incertae sedis. In addition, separate analyses are provided where better taxonomic resolution is needed. Living modes of coelomycetes Introduction Coelomycetes inhabit a wide range of ecological niches and occur as pathogens of terrestrial plants (Cortinas et al. 2006; Wikee et al. 2011; Udayanga et al. 2011; Maharachchikumbura et al. 2011, 2013b; Hyde et al. 2014) or aquatic plants (AlSaadoon and Al-Dossary 2014), as endophytes (Rajagopal et al. 2012), or saprobes (Wijayawardene et al. 2013a, 2014a, b; Dai et al. 2012, 2014a, b). Some are found on organic debris in soil (Someya et al. 1997), while others are lichenicolous (Diederich et al. 2001, 2012; Lawrey et al. 2011) or mycorrhizal (Oliveira et al. 2014). Some coelomycetous genera have been reported as pathogens of insects and vertebrates, including humans (de Hoog et al. 2000; El-Bassam et al. 2002; Cano et al. 2004; Krockenberger 2010). History Pathogenic coelomycetes Grove (1919) introduced the term coelomycetes, i.e. ‘fungi with a coelom or a cavity’, to accommodate the genera Phyllosticta, Phomopsis and Phloeospora, as they produce conidia within a cavity (Sutton 1980). The initial concept was extended to embody all genera that produce conidia within a cavity or cushionlike fungal matrix (Grove 1935, 1937). Later mycologists realized that coelomycetes are an artificial group of fungi (e.g. Taylor 1995) and the term was used purely for convenience (Kendrick 2000). The conidiomata or fruitbodies range from an enclosed cavity such as a pycnidium to a cushion-like acervulus, with several intermediaries viz. sporodochium-like and stroma (Fig. 1) (Sutton 1980; Nag Raj 1993; Kirk et al. 2008; Wijayawardene et al. 2012b). Fungal tissues, host tissues or a combination of both, line the cavities of a conidioma (Sutton 1980). There are a large number of taxa now known in the literature (Sutton 1980; Nag Raj 1993; Kirk et al. 2008; Wijayawardene et al. 2012b) and new taxa are continuously being introduced (Dai et al. 2012; Wijayawardene et al. 2014d, 2015; Ariyawansa et al. 2015b; Liu et al. 2015).

The impact of infection can extend to post-harvest losses and they may also be of quarantine concern (Hyde et al. 2014). Some genera are known to be seed pathogens causing discoloured areas, lesions on seed and seed mortality (Maden et al. 1975; Neergaard 1977). Because of their ubiquity and economic importance, much research effort has gone into their taxonomy, pathology, and detection methods, based on molecular techniques, as well as more traditional techniques. Ascochyta, Colletotrichum, Diplodia, Harknessia, Lasiodiplodia, Pestalotiopsis, Phaeophleospora, Phoma, Phomopsis and Phyllosticta are some well-known pathogenic genera, the species of which may cause considerable crop and post-harvest losses or reduce the aesthetic value in ornamental plants (Taylor and Crous 1999; Lee et al. 2004; Peever 2007; Peever et al. 2007; Udayanga et al. 2011, 2014; Wikee et al. 2011, 2013a, b; Damm et al. 2012, 2013, 2014; O’Connell et al. 2012; Phillips et al. 2012; Maharachchikumbura et al. 2011, 2013b, 2014; Hyde et al. 2014; Nilsson et al. 2014). Molecular techniques, in particular, have revealed that most pathogenic genera are actually ‘species complexes’ (Damm et al. 2012, 2013, 2014; Wikee et al. 2013a; Hyde et al. 2014). 19 Scientific Affiliate, Integrative Research Center, Science & Education, The Field Museum, Chicago, IL, USA Endophytic coelomycetes 20 Guizhou Key Laboratory of Agricultural Biotechnology, Guizhou Academy of Agricultural Sciences, Xiaohe District, Guiyang City, Guizhou Province 550006, People’s Republic of China 21 College of Science, Botany and Microbiology Department, King Saud University, Riyadh 1145, Saudi Arabia 22 Institute of Plant and Environment Protection, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, People’s Republic of China 23 The United Graduate School of Agricultural Sciences, Iwate University, 18-8 Ueda 3 chome, Morioka 020-8550, Japan The most accepted definition of plant endophytes was given by Petrini (1991), i.e. ‘All organisms inhabiting plant organs that at some time in their life, can colonize internal plant tissues without causing apparent harm to the host’. Endophytic taxa are important to host plants in various roles, such as being involved in mutualism, reducing herbivory, improving the ability of tolerance to drought conditions and diseases, plant health and eventually in decomposition after death (Frohlich et al. 2000; Sieber 2007; Hyde and Soytong 2008).

(d, e photo credit to A. Aptroot) fertile (ascoma-bearing) lichens may produce pycnidia on the same thallus (Fig. 3). Vobis and Hawksworth (1981) discussed four different types of conidiomata development in lichens; Lecanactis-type, Lobaria-type, Roccella-type and Xanthoriatype. They produce eight different morphological types of conidiophores (Fig. 4). There are no lichens that are strictlyspeaking lichen-forming coelomycetes, since all genera reported as such (e.g. Woessia) have also turned out to possess occasionally also fertile apothecia. Some species (e.g. Opegrapha spp.) often initially produce only pycnidia, and develop apothecia only in a later stage. Lichenicolous fungi ‘live exclusively on lichens, most commonly as host-specific parasites, but also as broad-spectrum pathogens, saprotrophs or commensals’ (Lawrey and Diederich 2015) (Fig. 5). Hawksworth (1981b) gave an overview of lichenicolous coelomycetes, accepting 22 genera and 42 species. Many species been added since, e.g. in the genera Ascochyta (Alstrup and Hawksworth 1990; Hawksworth and Kalb 1992), Cladoniicola (Diederich et al. 2001), Lichenodiplis (Diederich 2003; Atienza et al. 2009; Knudsen and Kocourkova 2009; Pérez-Vargas et al. 2013), Lichenoconium (Sutton 1980; Diederich 2003; Cole and Hawksworth 2004; Lawrey et al. 2011) and Microsphaeropsis (Etayo and Sancho 2008; Etayo and Yazici 2009; von Brackel 2014). Fungicolous coelomycetes Kirk et al. (2008) defined fungicolous fungi as ‘fungi growing on other fungi as parasites (‘mycoparasites’), commensals, or saprobes’. There are a few coelomycetes have been reported as fungicolous taxa, such as Ampelomyces, Capitorostrum and Neoheteroceras (Sutton 1980). Mycorrhizal coelomycetes Some species of coelomycetes have been reported from the rhizosphere of some plants. As an example, Corniculariella brasiliensis (Oliveira et al. 2014), Phomopsis columnaris and Phoma schachtii (Vaz et al. 2012) have been reported from the rhizosphere regions of Caesalpinia echinata and Sorghum vulgare, respectively, and may have a close, mutualistic relationship with the plant. However, the available information for mycorrhizal coelomycetes lacks comparison with other life modes.

Kendrick (2000) stated that ‘the production of conidia in enclosed structures or the absence of such enclosure’ could be the basic criterion to define a particular fungus as coelomycetous or hyphomycetous. Below we quote the most accepted definitions for coelomycetes and hyphomycetes and these are followed in this study. Coelomycetes: ‘…conidia are formed within a cavity lined by either fungal tissue, host tissue, or a combination of both’ (Sutton 1980). Hyphomycetes: ‘form their conidia on or from conidiophores that may be single or aggregated into synnemata (coremia) or sporodochia, but never develop under the shelter of any protective integument’ (Kendrick and Nag Raj 1979). Placing genera with different types of conidiomata (viz. pycnidia, acervuli, sporodochia, synnemata and other intermediate forms) in coelomycetes or hyphomycetes has been thoroughly discussed (Kendrick and Nag Raj 1979; Sutton 1980; Nag Raj 1993; Kirk et al. 2008; Seifert et al. 2011). Kendrick and Nag Raj (1979), Kendrick (2000) and Seifert et al. (2011) clearly defined the boundaries and treated acervuli and Fig. 6 Matured sporodochium-like conidiomata and their vertical sections when immature. a Mature, sporodochium-like conidiomata of Scolicosporium minkeviciusii. b Vertical section of immature conidioma. c Different stages of maturity of conidiomata of Phragmotrichum platanoidis. Arrow heads point to the immature pycnidia as conidiomata of coelomycetes, while considering sporodochia and synnemata as hyphomycetous. Kendrick and Nag Raj (1979) listed four criteria to qualify a conidioma as an acervulus: 1. The hymenium develops beneath an integument entirely of host origin 2. Conidiogenous cells are restricted to the floor of the cavity 3. At maturity, there is usually a split of the host integument, and considerable exposure of the relatively flat hymenium 4. The hymenium layer arises from a more or less welldeveloped pseudoparenchymatous stroma that forms at some level within the tissue of the host (Adopted from Kendrick and Nag Raj 1979) Seifert et al. (2011) defined sporodochia as, ‘cushion-like conidiomata with an open mass of conidia; usually with conidiophores arising from a basal mass of interwoven or stromatic hyphae. Sporodochia are ‘usually superficial on the host tissue, but can sometimes be subcuticular or semiimmersed, and are then difficult to distinguish from acervuli’ (Seifert et al. 2011). However, in cultures it is difficult to differentiate acervuli from sporodochia (Seifert et al. 2011). Sutton’s (1980) treatment partially agreed with the above definitions, but he did regard a few genera with ‘erumpent and sporodochial conidiomata’ (e.g. Phlyctema) as coelomycetes, conidiomata beneath the host tissue. d Conidioma wall and host tissue. e Mature, sporodochium-like conidiomata of Blastacervulus eucalypti. f Vertical section of conidioma. Sporodochium-like mature conidioma on left and acervular closed conidioma on right side Fungal Diversity thus accepting that in some fungi there is a transition between sporodochia and acervuli. Sutton (1980) further mentioned that there is no real generic distinction between acervular and sporodochial fungi. By accepting this statement, several species with acervular to sporodochial conidiomata (e.g. Rhizosphaerina fide Sutton 1985; Lecanostictopsis fide Sutton and Crous 1997) or with sporodochial-like conidiomata (Minutoexcipula fide Atienza and Hawksworth 1994; Atienza et al. 2009) have been described as coelomycetous. Thus, some species within a genus have been regarded as hyphomycetes with sporodochia, while others in the same genus are considered to be coelomycetes. Hence, we consider that it is important to observe a series of vertical sections of immature and mature conidiomata before they can be regarded as sporodochia or acervuli (Fig. 6). Classification and taxonomy Historical classification Hughes’ (1953) publication on conidiogenesis can be recognized as a significant landmark in traditional classification of asexual fungi that helped to develop a new understanding in the taxonomy of the conidial fungi. Even though Hughes (1953) introduced his findings based on hyphomycetes, Sutton (1971a, 1973) recognized similarities in conidium ontogeny with coelomycetous fungi. Hence, subsequent Fig. 7 Different modes of conidiogenesis. a–d Arthric conidiogenesis in Trullula sp. e–g Arthric conidiogenesis in Phragmotrichum with basipetal conidial chains. h–k Blastic conidiogenesis in Asterosporium publications in pycnidial fungi by Sutton (1980) and Nag Raj (1981) considered conidiogenesis as a primary taxonomic criterion in the classification of coelomycetes. Sutton (1980) introduced six suborders based on conidiogenesis and other important characters, such as types of conidiomata (Fig. 1), conidiogenous cells (Fig. 7), origin of conidium wall, conidial morphology (Fig. 8), conidial septation and behaviour of these fungi in culture. However, Sutton’s (1980) classification is not accepted as a natural classification scheme as it does not show evolutionary relationships (de Gruyter et al. 2009; Aveskamp et al. 2010). For example, Sutton (1980) grouped Lecanosticta and Stilbospora together with 43 other genera (including seve r a l a pp en d ag e be ar i n g g e ne r a ) i n t he s ub or de r Blastostromatineae. Recent sequence based phylogenetic analyses have shown that these two genera have quite distinct lineages, viz. Mycosphaerellaceae, Capnodiales (Crous et al. 2009a; Quaedvlieg et al. 2014) and Stilbosporaceae, Diaporthales (Voglmayr and Jaklitsch 2014) respectively. Nevertheless, Sutton (1980) was correct in some cases such as with Stilbospora and Stegonsporium, which have been shown as close relatives in Stilbosporaceae, Diaporthales (Voglmayr and Jaklitsch 2014). Plasticity in coelomycetous fungi resulted in poor delimitation and understanding of generic and species boundaries (Sutton 1977, 1980; Nag Raj 1981; Wijayawardene et al. 2012b). Pilidiella and Coniella are good examples of such a poor generic delimitation, where the former was treated as a synonym of the latter by Sutton (1980) and Nag Raj (1993). sp. l–p Phialidic conidiogenesis in Pseudocamarosporium sp. p–s Annellidic conidiogenesis in Botryosphaeria sp.

Coniothyrium-like and microsphaeropsis-like taxa are other examples of morphological plasticity among coelomycetes (Sutton 1980). Thus, early morphology-based identifications are questioned in recent studies (Verkley et al. 2004, 2014; de Gruyter et al. 2013). Besides Sutton’s (1973, 1980) criteria for determining suprageneric and generic boundaries, Nag Raj (1993) considered the types of appendages as a key factor in establishing generic boundaries. It has been a practice to delimit fungal taxa, based on conspicuous morphological characters. Swart and Williamson (1983) established Vermisporium to accommodate several Seimatosporium species with hyaline to sub-hyaline, uniformly thin-walled conidia and 10–20 times as long as they are wide. Nag Raj (1993) accepted Vermisporium as a distinct genus and recognised ten species. However, Barber et al. (2011) showed through sequence analyses that the type species of Vermisporium, V. walkeri H.J. Swart & M.A. Will. and several other species cluster with Seimatosporium sensu stricto and thus were treated as a synonym of Seimatosporium. Pilidiella eucalyptorum is an example of confusion in a species. Although it has morphological characters similar to Coniella, sequence analyses show that it is closer to Pilidiella sensu stricto (van Niekerk et al. 2004). Thus, it is important to rely on sequence based taxonomic and phylogenetic analyses rather than solely on morphology. A polyphasic approach is more reliable in many disciplines such as quarantine and plant pathology (Cai et al. 2009; Aveskamp et al. 2010; Wang et al. 2012; Wijayawardene et al. 2012c; Hyde et al. 2014). Coelomycetes and their sexual morphs Ainsworth (1966) proposed to place asexual fungi in a separate subdivision, Deuteromycotina which has been subdivided into three classes, viz. Hyphomycetes, Coelomycetes and Agonomycetes (Mycelia sterilia) (Sutton 1980). However, Kendrick (1979) emphasised the importance of integrating conidial fungi into the natural classification and Kendrick (1989) considered Deuteromycotina to be a ‘fungal chimera’. Kendrick (1989) emphasized that the whole fungus or holomorph can be ‘teleomorph + anamorph’ or ‘teleomorph’ or ‘anamorph’. The last expression is an important phenomenon among taxonomists who study the conidial fungi and it clearly shows the importance of incorporating them in natural classification system (Kendrick 1989; Hyde et al. 2011, 2013; Wijayawardene et al. 2012b, c; Maharachchikumbura et al. 2015). Currently, more than 1000 coelomycetous genera have been described and approximately 300 genera are linked with sexual morphs or placed in various families, orders or classes (Wijayawardene et al. 2012b). Thus, most of the known genera are treated as ‘orphan genera’ (Wijayawardene et al. Fig. 9 The best scoring RAxML tree of species of Dothideomycetes, Leotiomycetes and Sordariomycetes generated from analyses of combined of LSU, SSU, RPB2 and TEF1-α sequence data. Bootstrap values greater than 50 % are given above the nodes. The original strain numbers are given after the species names. Classes are differentiated with alternative colours in the right justified column. The tree is rooted to Saccharomyces cerevisiae 2012b). Recent studies based on sequence analyses have facilitated taxonomic placement of some of these orphan genera (Wingfield et al. 2012; Wijayawardene et al. 2014d; Maharachchikumbura et al. 2015). Polyphyletic genera, convergent evolution Traditionally, taxonomists used culture-based methods or cooccurrence of different morphs on the same host to determine sexual/ asexual links (Wijayawardene et al. 2014d; Maharachchikumbura et al. 2015). However, due to the morphological plasticity of coelomycetes, some genera have been linked with several sexual morphs or assigned in different taxonomic groups and thus are called as ‘polyphyletic genera’ (Wijayawardene et al. 2012b). For example, Camarosporium was treated as an asexual genus in Botryosphaeriales (Liu et al. 2012; Wijayawardene et al. 2012b), Cucurbitariaceae (Doilom et al. 2013) and Leptosphaeriaceae (Schoch et al. 2009). Based on sequence data analyses, Wijayawardene et al. (2014d) showed that camarosporium-like taxa are polyphyletic in Pleosporales, but Camarosporium sensu stricto resides as a distinct clade in Pleosporineae, Pleosporales. The genera such as Coniothyrium, and Phoma were also treated as polyphyletic and recent sequence based analyses have helped to demarcate generic boundaries and thus introduce several new genera (Verkley et al. 2004; de Gruyter et al. 2009, 2013; Crous et al. 2011b). Molecular studies have also helped to understand convergent evolution, i.e. ‘the independent origin of similar organismic forms, as tantamount to experimental replication in the history of life and indicative of the robust counterfactual resilience of macro evolutionary pattern in the fungi’ (Powell 2008). Morphologically similar Homortomyces and Stilbospora are extraordinary examples of convergent evolution, where the former resides in class Dothideomycetes, while the latter is placed in class Sordariomycetes (Crous et al. 2012b; Wijayawardene et al. 2014e). Aim of the paper Even though sequence analyses play an important role in the identification of fungi in modern-day fungal taxonomy, morphology is still a key factor. Therefore, it is essential to consider both molecular data and morphology when identifying fungi. As most of described fungal genera lack sequence data, we have to rely on morphological descriptions in the old literature before deciding to introduce new genera or species.

(2011) present all available data on hyphomycetous fungi including illustrations, which helps to understand them at generic level. There has been no overview of the coelomycetous fungi with a compilation of taxonomic notes and other details, since Sutton (1980). Nag Raj (1993) is useful for identification of appendage bearing coelomycete genera. Some of the content of both works needs to be revised, as both monographs are based only on morphology and used an artificial classification system. Thus, it is necessary to incorporate both morphological data and known sequence data to obtain a natural classification. In this paper, we list all dematiaceous coelomycetous genera as an outline and provide generic descriptions. Moreover, illustrations and taxonomic notes are also provided. For the genera and species where sequence data are available, phylogenetic analyses were carried out to determine taxonomic placements in a natural classification system. Materials and Methods Literature and preparation of the list Previous publications (including monographs, check lists, dictionaries) were divided in to two chronological groups for the convenience of collecting data: 1. Prior to Sutton (1977, 1980), i.e. ‘Coelomycetes VI. Nomenclature of generic names proposed for coelomycetes’ and ‘The coelomycetes. Fungi imperfecti with pycnidia, acervuli and stromata’ respectively. 2. Post Sutton (1980) until the end of 2015; including Nag Raj (1993), Kirk et al. (2008, 2013), Hyde et al. (2011); Wijayawardene et al. (2012a) and other publications introducing new genera or proving sexual-asexual links. We used Sutton (1977, 1980) and Kirk et al. (2008) as baseline data for selecting valid generic names (see outline), while eliminating synonyms from groups one and two respectively. Besides the non-pleomorphic genera, we used the recently accepted generic names for pleomorphic genera (that is, they occur as sexual and asexual states through their life history, but may be separated in time and space fide Kendrick 1979) based on Johnston et al. (2014), Stadler et al. (2014), Wijayawardene et al. (2014c) and Maharachchikumbura et al. (2015). For example, Teratosphaeria will be used instead of Colletogloeopsis and Kirramyces. Basionyms and (putative) synonyms of the genus are listed, except when there are more than three. Layout of the paper Each genus is provided with a generic description which is based on the protologue and subsequent publications. Notes include the genus history, comparisons with other morphologically similar genera, sexual morph links, taxonomic placement and molecular phylogeny, when available. The type species is illustrated in most cases and taxonomic keys for species are provided where possible. Glossary We followed Sutton (1980) and Kirk et al. (2008) as baselines for terms used in this study. Sample collection, specimen examination and isolation Fresh collections were made in China, Germany, Italy and Thailand. The collected samples were examined with a Motic SMZ 168 stereo microscope and sterilized needles were used to remove conidiomata, which were mounted in water. Sections of conidiomata were made with a razor blade or freezing microtome. Photographs of micro characters (such as conidiomata wall, paraphyses, conidiophores, conidiogenous cells, conidia) were made from material mounted in water or lactophenol using ECLIPSE 80i light microscope with a Cannon 450D digital camera. Type and voucher specimens were deposited in the herbarium of Mae Fah Luang University (MFLU), Chiang Rai, Thailand, Kunming Institute of Botany (HKAS), China and Agriculture College, Guizhou University (HGUP), China. Isolation of fungus was carried out by single spore isolation following the method of Chomnunti et al. (2014). Germinating spores were transferred to PDA and incubated at 18 °C. The cultural characteristics (e.g. colour, texture) were also determined. The living ex-type cultures and authentic cultures were deposited at the Mae Fah Luang University Culture Collection (MFLUCC) with duplicates at Kunming Institute of Botany Culture Collection (KUMCC) and Guizhou University Culture Collection (GUCC). Faces of Fungi numbers are provided as in Jayasiri et al. (2015) and Index Fungorum numbers as in Index Fungorum (2016). Type or representative specimens were studied from Queensland Department of Agriculture and Fisheries (BRIP), Australia, Landcare Research (PDD), New Zealand, Hirosaki University (HHUF), Kunming Institute of Botany Academia Sinica (HKAS), China, Research Institute of Resource Insects (IFRD), U.S. National Fungus Collections (BPI), U.S.A. Maryland and CABI Bioscience UK Centre (IMI), U.K. England. DNA extraction, PCR amplification, sequencing A modified protocol in BIOMIGA Fungus Genomic DNA Extraction Kit (GD2416) was used to extract DNA from fresh mycelium scraped from the colony margin of cultures grown on PDA for 2–3 weeks at 18 °C.

Agarose electrophoresis gel (1 %) stained with ethidium bromide was used to visualize DNA products. Amplified genes were sequenced by SinoGenoMax Co., Beijing, China and the nucleotide sequences were deposited in GenBank. Phylogenetic analyses Additional sequences were downloaded from GenBank (Supplementary Table 1) based on blast searches and recently published data. Separate phylogenetic analyses were carried out for different nomenclature hierarchy (Kirk et al. 2008) with different genes following recently published literature (Table 2). Sequences were initially aligned by MAFFT v. 7 (http://mafft.cbrc.jp/alignment/ server/index.html) using the default settings and improved manually where necessary with MEGA v. 5.2.2 (Kumar et al. 2012) or BioEdit v. 7.0.5.2 (Hall 1999). Evolutionary models for phylogenetic analyses were selected independently for each locus using MrModeltest v. 3.7 (Posada and Crandall 1998) under the Akaike Information Criterion (AIC) implemented in both PAUP v. 4.0b10 and MrBayes v. 3. Phylogenetic reconstructions of combined gene trees were performed by Bayesian Inference (BI) and Maximum Likelihood (ML). Maximum-likelihood (ML) analysis was performed in RAxML (Stamatakis 2006) implemented in raxmlGUI v.0.9b2 (Silvestro and Michalak 2010), employing mixed models of evolution settings of the program and bootstrap support was obtained by running 1000 pseudo replicates. The online tool Findmodel was used to determine the best nucleotide substitution (http://www.hiv.lanl.gov/content/ sequence/findmodel/findmodel.html) model for each partition. Maximum Likelihood bootstrap values (ML) equal to or greater than 70 % are given above each node. Bayesian analyses was conducted with MrBayes v. 3.1.2 (Huelsenbeck and Ronquist 2001) to valuate Posterior probabilities (PP) (Rannala and Yang 1996; Zhaxybayeva and Gogarten 2002) by Markov Chain Monte Carlo sampling (BMCMC). Two parallel runs were conducted, using the default settings, but with the following adjustments: Six simultaneous Markov chains were run for 2,000, 000 generations and trees were sampled every 100th generation and 20,000 trees were obtained. The first 4000 trees, representing the burn-in phase of the analyses and discarded. The remaining 16,000 trees were used for calculating PP in the majority rule consensus tree (Ariyawansa et al. 2015a). Branches with Bayesian posterior probabilities greater than 0.95 are given in bold. Maximum-Parsimony (MP) analyses were carried out using PAUP v. 4.0b10 (Swofford 2002) using the heuristic search option with 1000 random taxa addition and tree bisection and reconnection (TBR) as the branch swapping algorithm. All characters were unordered and of equal weight. The gaps were treated as missing data. The Tree Length (TL), Consistency Indices (CI), Retention Indices (RI), Rescaled Consistency Indices (RC) and Homoplasy Index (HI) were calculated for each tree generated. Phylograms were visualized with Treeview v. 1.6.6 (Page 1996) or FigTree v1.4.0 program (Rambaut 2012) and reorganized in Microsoft power point (2010) and Adobe Illustrator® CS5 (Version 15.0.0, Adobe®, San Jose, CA). Fungal Diversity Fig. 10 One of the 16 equally most parsimonious trees obtained from the combined SSU, LSU, ITS, EF1-α and β-tubulin data set (CI = 0.527, RI = 0.751, RC = 0.396, HI = 0.473). MP values (>70 %) resulting from 1000 bootstrap replicates and Bayesian posterior probabilities above 0.95 are given at the nodes. The tree was rooted to Melanops tulasnei (CBS 116805). Ex-type strains are in bold and newly introduced species are in blue. Genera are indicated in different colours to the right of the tree and dematiaceous coelomycetous and holomorph with dematiaceous coelomycetous genera are in red Fungal Diversity Results Phylogenetic analyses The classes Dothideomycetes, Leotiomycetes and Sordariomycetes based on analyses of LSU, SSU, RPB2, and TEF1-α sequence data The combined LSU, SSU, RPB2, and TEF1-α data set consists of 903 strains with Saccharomyces cerevisiae as the out group taxon. The placements of dematiaceous coelomycetous genera are listed in the outline (Fig. 9). Botryosphaeriaceae based on analyses of SSU, LSU, ITS, TEF1-α and β-tubulin sequence data The combined SSU, LSU, ITS, TEF1-α and β-tubulin data set consisted of 70 strains with Melanops tulasnei (CBS 116805) as the outgroup taxon. The data set consisted of 3280 characters of which 2514 characters were constant, 179 variable parsimony-uninformative characters and 587 parsimonyinformative characters. One of most parsimonious trees is shown in Fig. 10 (CI = 0.527, RI = 0.751, RC = 0.396, HI = 0.473). The tree comprises 21 genera viz. Alanphillipsia, Barriopsis, Botryobambusa, Botryosphaeria, Cophinforma, Diplodia, Dothiorella, Endomelanconiopsis, E u t i a ro s p o re ll a , L a s i o d i p l o d i a , M a c ro p h o m i n a , Marasasiomyces, Mucoharknessia, Neodeightonia, Neofusicoccum, Neoscytalidium, Phaeobotryon, Sakireeta, Spencermartinsia, Sphaeropsis and Tiarosporella. Our results agree with Phillips et al. (2013) and Crous et al. (2015b) but neither of those publications included Alanphillipsia. Based on our phylogenetic analyses (Fig. 10), we accept Alanphillipsia as a genus in Botryosphaeriaceae. Dichomera-like taxa group in both Botryosphaeria and Neofusicoccum clades. Hence, separate analyses were carried out using only dichomera-like species, Botryosphaeria species and Neofusicoccum species. Capnodiales based on analyses of LSU, RPB2, ITS, β-tubulin and TEF1-α sequence data The combined LSU, RPB2, ITS, β-tubulin and TEF1-α data set consists of 83 strains with Parastagonospora nodorum (CBS 110109) as the out group taxon. Our maximumlikelihood analyses (Fig. 11) agree with Wijayawardene et al. (2014c) in which Capnodiales comprises eight families viz. Capnodiaceae, Cladosporiaceae, Dissoconiaceae, Extremaceae, Mycosphaerellaceae, Neodevriesiaceae, Schizothyriaceae and Teratosphaeriaceae. Teratosphaeriaceae comprises Camarosporula, Readeriella sensu stricto, Leptomelanconium sensu lato (current name Teratosphaeria australiensis) and Teratosphaeria sensu stricto (including Colletogloeopsis and Kirramyces) and Xenoconiothyrium. Phaeophleospora sensu stricto and Lecanosticta sensu lato group in Mycosphaerellaceae. However, Phaeophleospora eugeniae, the type species of Phaeophleospora separate with moderate bootstrap support (75 %) from other Phaeophleospora species which have hyaline conidia. Readerielliopsis does not group in any family and is thus treated as Capnodiales, genera incertae sedis. It could be a new phylogenetic lineage in Capnodiales. Diaporthales based on analyses of LSU and ITS sequence data The combined LSU and ITS data set consists of 73 strains with Coniochaeta velutina (UAMH 10912) as the out group taxon. The best scoring RAxML tree for species of Diaporthales is shown in Fig. 12. Maharachchikumbura et al. (2015) accepted twelve families in Diaporthales viz. Cryphonectriaceae, Diaporthaceae, Gnomoniaceae, Harknessiaceae, Melanconidaceae, Pseudoplagiostomataceae, Pseudovalsaceae, Schizoparmeaceae, Stilbosporaceae, Sydowiellaceae, Tirisporellaceae and Valsaceae. Crous et al. (2015a) introduced Macrohilaceae to accommodate Macrohilum. Our DNA sequence analyses agree with both Crous et al. (2015a) and Maharachchikumbura et al. (2015) and confirm that Diaporthales comprises 13 families. Apoharknessia, Greeneria and Lasmenia do not cluster in any family, thus, are treated as Diaporthales, genera incertae sedis. Dichomera-like taxa in Botryosphaeriaceae based on combined analyses of ITS and TEF1-α sequence data The combined ITS and TEF1-α data set consists of 55 strains with Neoscytalidium dimidiatum (CBS 145.78, PWQ2361) as the out group taxon. The data set consists of 856 characters of which 636 are characters are constant, 30 are variable parsimony-uninformative characters and 190 are parsimony-informative characters. One of the 12 equally most parsimonious trees is shown in Fig. 13. Our new strain of dichomera-like taxon (MFLUCC 14– 0459) and Dichomera saubinetii (CBS 990.70) cluster in Botryosphaeria, hence former strain introduce as Botryosphaeria quercus. The type species of Dichomera, D. saubinetii lacks an ex-type strain thus we do not treat Dichomera as a synonym of Botryosphaeria. Dichomera versiformis and D. ecucalypti group with Neofusicoccum, hence, this confirms that dichomera-like taxa are paraphyletic in Botryosphaeriaceae. Fungal Diversity Fig. 11 The best scoring RAxML tree of species of Capnodiales generated from analyses of combined of LSU, RPB2, ITS, β-tubulin and TEF1-α sequence data. Bootstrap values greater than 70 % and Bayesian posterior probabilities above 0.95 are given above the nodes. The original strain numbers are given after the species names. Ex-type strains are emphasized in bold. Families are differentiated with alternative colours in the right justified column. The dematiaceous coelomycetous genera are named in the column to the right of the main tree and indicated with different colours. The tree is rooted to Parastagonospora nodorum (CBS 110109) Fungal Diversity Floricolaceae based on combined analyses of LSU, SSU and ITS sequence data Xylariomycetidae based on combined analyses of LSU, ITS, SSU, β-tubulin and RPB2 sequence data The combined LSU, SSU and ITS data set consists of 25 strains with Platystomum scabridisporum (BCC22835) as the out group taxon. The best scoring RAxML tree is shown in Fig. 14. In their analyses, Thambugala et al. (2015) showed that Floricolaceae comprises nine genera i.e. Asymmetrispora, Aurantiascoma, Floricola, Magnibotryascoma, Misturatosphaeria, Neocurreya, Pseudoaurantiascoma, Pseudomisturatosphaeria and Ramusculicola. Our results agree with findings in Thambugala et al. (2015) and new strain of coniothyrium-like taxon (MFLUCC 12–0328) clusters as a distinct clade in Floricolaceae, thus Paulkirkia is introduced. Curreya acacia (CPC 24801) (Crous et al. 2015c) clusters in Neocurreya sensu stricto thus Neocurreya acaciae is introduced as a new combination. The combined analyses of LSU, ITS, SSU, β-tubulin and RPB2 dataset comprises 68 strains with Dothidea hippophaeos (AFTOL-ID 919) and D. sambuci (DAOM 231303) as the out group taxa. The best scoring RAxML tree is shown in Fig. 16. Xylariomycetidae comprises 16 families. The clade of Bartaliniaceae is supported by high bootstrap value and PP values (100 % and 1.00) and comprises Bartalinia, Broomella, Hyalotiella, Morinia, Truncatella and Zetiasplozna. Senanayake et al. (2015) did not include Morinia as a genus in Bartaliniaceae but our analyses show it is a well-established genus. Senanayake et al. (2015) accepted Robillarda in Amphisphaeriales, genera incertae sedis but Crous et al. (2015a) showed Robillarda has a distinct phylogenetic lineage in Xylariales thus introduced Robillardaceae. However, in our analyses, Robillardaceae clusters in Amphisphaeriales. Massarineae based on combined analyses of LSU, ITS and SSU sequence data The combined LSU, SSU and ITS data set consists of 83 strains with Pleospora herbarum (CBS 191.86 and MFLUCC 13–0344) and Pleospora tarda (CBS 714.68) as the out group taxa. The best scoring RAxML tree is shown in Fig. 15. Our results agree with Tanaka et al. (2015) and Massarineae comprises 12 families i.e. Bambusicolaceae, Dictyosporiaceae, Didymosphaeriaceae, Latoruaceae, Lentitheciaceae, Morosphaeriaceae, Macrodiplodi opsidaceae , Massarinaceae, Parabambusicolaceae, Periconiaceae, Sulcatisporaceae and Trematosphaeriaceae. Didymosphaeriaceae comprises Alloconiothyrium, Paracamarosporium, Paraconiothyrium, Pseudocamarosporium, Verrucoconiothyrium and Xenocamarosporium which have been reported as dematiaceous coelomycetes (Ariyawansa et al. 2014b; Wijayawardene et al. 2014c, d; Tanaka et al. 2015). Further, Kalmusia and Paraphaeosphaeria which were reported with brown spored coelomycetous morphs also clustered in Didymosphaeriaceae (Ariyawansa et al. 2014b; Liu et al. 2015). Phragmocamarosporium and Suttonomyces group in Massarinaceae and Lentitheciaceae respectively and these results agree with Tanaka et al. (2015) and Wijayawardene et al. (2015). Murilentithecium also groups in Lentitheciaceae agreeing with Wanasinghe et al. (2014). Magnicamarosporium and Sulcatispora cluster in Sulcatisporaceae while Macrodiplodiopsis and Camarographium koreanum groups in Macrodiplodiopsidaceae as in Tanaka et al. (2015). Fuscostagonospora did not cluster in any family, thus, is treated as Massarineae, genus incertae sedis. Taxonomy and outline for genera of dematiaceous coelomycetes The section starts with an account of the various structures and terminology of coelomycetes which are illustrated with photomicrographs and/or line drawings. An outline of the coelomycetes and their placement in the natural classification is provided and is based on an update of recent publications on Dothideomycetes (Hyde et al. 2013; Wijayawardene et al. 2014c), Leotiomycetes (Johnston et al. 2014) and Sordariomycetes (Stadler et al. 2014; Maharachchikumbura et al. 2015; Senanayake et al. 2015). An account for each genus is provided with a generic description, and the illustration of one or more species. Outline for dematiaceous coelomycetes Phylum ASCOMYCOTA Caval-Sm.

Hawksw., Lichenologist 40(2): 105 (2008) Facesoffungi number: FoF 01416; Fig. 17 Ascomycota, genus incertae sedis Lichenicolous. Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, single, or sometimes gregarious, immersed to partly erumpent, subglobose, black, ostiolate, with a distinctly thickened, ostiolar collar. Conidiomata wall composed of polyhedral angular pseudoparenchymatous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, not proliferating and lacking annellations, broadly short-ampulliform, apex with a periclinal thickened collar, hyaline. Conidia single, ellipsoid, rounded at both ends, aseptate, hyaline at maturity, becoming pale brown at maturity while inside the pycnidial cavity, smooth-walled (description modified from Kocourková and Hawksworth 2008). Type species: Acaroconium punctiforme Kocourk. & D. Hawksw., Lichenologist 40(2): 105 (2008); Fig. 17 Notes: Kocourková and Hawksworth (2008) introduced Acaroconium with A. punctiforme as the type species. Acaroconium morphologically resembles Phoma sensu lato as both genera have ‘conidiomata with a deeply pigmented region around the well-defined ostiole’ (Kocourková and Hawksworth 2008). However, Phoma species have hyaline conidia (de Gruyter et al. 2009, 2013), while Acaroconium has brown conidia. The comparison of Acaroconium with other lichenicolous genera and taxonomic keys are provided under notes in Lichenoconium. Sequence data is unavailable, thus the taxonomic status is unknown. Alanphillipsia Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol. Fungi 31: 197 (2013) Facesoffungi number: FoF 01417; Fig. 18 Dothideomycetes, order incertae sedis, Botryosphaeriales, Botryosphaeriaceae Endophytic, saprobic or possibly pathogenic, associated with leaf lesions. Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, immersed, globose, central, dark brown, ostiolate. Conidiomata wall composed of brownwalled cells of textura angularis. Paraphyses subcylindrical, unbranched or branched at base, aseptate or transversely septate, with obtuse to subobtuse apices, hyaline, smooth-walled. Conidiophores subcylindrical, flexuous or straight, septate, hyaline, smooth-walled. Macroconidiogenous cells proliferating percurrently, subcylindrical to lageniform, terminal, integrated, hyaline, smooth. Macroconidia ellipsoid to obclavate or subcylindrical with truncate scar on hyaline layer, solitary, hyaline when young, becoming goldenbrown to medium brown, verruculose, granular to guttulate, surrounded by a persistent, hyaline outer layer (absent in some species, or reduced to a basal frill or basal and apical appendage). Microconidiogenous cells in the same conidioma, hyaline, smooth, subcylindrical, proliferating inconspicuously percurrently at apex. Microconidia subcylindrical to ellipsoid, apex obtuse, base truncate, hyaline, smooth-walled, granular, with a minute marginal frill (description modified from Crous et al. 2013, 2014c). Type species: Alanphillipsia aloes Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol. Fungi 31: 197 (2013); Fig. 18 Notes: Crous et al. (2013) introduced the genus Alanphillipsia with A. aloes as the type species. In morphology, Alanphillipsia resembles Aplosporella (Sutton 1980; Slippers et al. 2013), but the former is somewhat distinct as it has a hyaline outer layer (Crous et al. 2013). Crous et al. (2013) compared Alanphillipsia with Cytosphaera, but the latter genus has erumpent to superficial stromatic conidiomata and hyaline conidia (Sutton 1980). Fungal Diversity Fig. 13 One of the 12 equally most parsimonious trees obtained from combined analyses set of ITS and EF1-α sequence data. (CI = 0.738, RI = 0.941, RC = 0.695, HI = 0.262). MP values (>70 %) resulting from 1000 bootstrap replicates and Bayesian posterior probabilities above 0.95 are given at the nodes. The tree was rooted to Neoscytalidium dimidiatum (CBS 145.78, PWQ2361). Ex-type strains are in bold and newly introduced species are in blue Based on a megablast search of NCBI’s GenBank nucleotide database, Crous et al. (2013) concluded that Alanphillipsia belongs in Botryosphaeriaceae. Wijayawardene et al. (2014c) also listed Alanphillipsia under Botryosphaeriaceae and our sequence analyses agree with this (Figs. 9 and 10). Alfaria Crous et al. Persoonia, Mol. Phyl. Evol.

Sexual morph: see Crous et al. (2014b). Asexual morph: Conidiomata acervuli, solitary to gregarious, semi-immersed to immersed, slightly depressed, globose to subglobose, unilocular, greenish dark brown to black, with a centrally located ostiole. Conidiomata wall composed of thick-walled, brown to dark green cells of textura angularis. Conidiophores cylindrical, long, hyaline, aseptate, unbranched. Conidiogenous cells enteroblastic, phialidic, cylindrical, integrated, terminal, slightly tapering towards apex. Conidia ellipsoidal, truncate base, aseptate, pale brown when young, becoming dark brown at maturity, smooth and thickwalled, with an irregular mucilaginous appendages. Type species: Alfaria cyperi-esculenti Crous et al., Persoonia, Mol. Phyl. Evol. Fungi 32: 239 (2014) Notes: The genus Alfaria was introduced by Crous et al. (2014b) to accommodate a sexual taxon with ‘fusoid-ellipsoid, 0–3-septate, hyaline, ascospores with mucoid sheaths or mucoid caps’ (Crous et al. 2014b). In our sequence analyses (Figs. 9 and 20), a new collection from Italy also grouped with the type species of Alfaria, A. cyperi-esculenti with high bootstrap values (100 %) and high PP values (1.00). Alfaria clusters in Stachybotriaceae, Hypocreales (Fig. 20). Alloconiothyrium Verkley et al., Persoonia, Mol. Phyl. Evol.

Asexual morph: Conidiomata pycnidial or stromatic, uni- or multi-locular, black. Conidiomatal wall composed of an outer layer of thick-walled, brown cells of textura angularis and an inner layer composed of thick-walled, hyaline cells of textura angularis or textura globulosa. Conidiogenous cells enteroblastic, annellidic, broadly ampulliform, discrete, with several distinct percurrent proliferations. Conidia globose to irregularly ellipsoid, initially hyaline, after secession olivaceous-brown, orange-brown at maturity, aseptate, verruculose, with 1 large oil-droplet. Chlamydospores formed in the mycelium, terminal or intercalary, brown, solitary, globose, with large droplets, smooth-walled (description modified from Verkley et al. 2014). Type species: Alloconiothyrium aptrootii Verkley et al., Persoonia, Mol. Phyl. Evol. Fungi 32: 33 (2014); Fig. 21 Notes: Verkley et al. (2014) introduced Alloconiothyrium with A. aptrootii as the type species. In their sequence analyses, Verkley et al. (2014) showed that their coniothyrium-like collection from soil grouped in Didymosphaeriaceae, Massarineae. Coniothyrium sensu stricto grouped in Coniothyriaceae, Pleosporineae (de Gruyter et al. 2013; Verkley et al. 2014; Wijayawardene et al. 2014d) and is characterised by 1-septate conidia (Sutton 1980), thus the new collection is morphologically and phylogenetically distinct from Coniothyrium sensu stricto. Paraconiothyrium and Verrucoconiothyrium are also well-established genera in Didymosphaeriaceae (Verkley et al. 2004, 2014; Ariyawansa et al. 2014b; Wijayawardene et al. 2014d), but Paraconiothyrium and Verrucoconiothyrium are phylogenetically distinct from Alloconiothyrium (Figs. 9 and 15).

The tree is rooted to Dothidea hippophaeos (AFTOL-ID 919) and D. sambuci (DAOM 231303) Camarographium. Amarenographium shows distinct morphology from Camarographium with branched and long conidiogenous cells and appendage bearing conidia (Eriksson 1982; Nag Raj 1993). Nag Raj (1993) stated that Amarenographium metableticum also has a microconidial stage. Fungal Diversity Fig. 17 Acaroconium punctiforme. a Vertical section of conidioma. b Conidia. Scale bars: a = 20 μm, b = 10 μm (re-drawn from Kocourková and Hawksworth 2008) Eriksson (1982) treated Amarenomyces ammophilae (Lasch) O.E. Erikss. as the sexual morph of Amarenographium metableticum as both species occur together and resemble each other in morphology. Nag Raj (1993) also mentioned Amarenomyces is the sexual morph of Amarenographium. However, this connection is not confirmed by molecular data or culture based methods, thus Phookamsak et al. (2014) and Wijayawardene et al. (2014c) treated Amarenographium and Amarenomyces as distinct genera in Phaeosphaeriaceae. Amarenographium comprises three species viz. A. metableticum, A. sinense Joanne E. Taylor et al. (Taylor and Hyde 2003) and A. solium Abdel-Wahab et al. (AbdelWahab et al. 2012). Sequence data is available for A. solium and for the new species we introduce here. However, in our sequence analyses, A. solium groups as the sister clade to Julella sensu stricto with low bootstrap support (60 % in ML analysis) while our new strain groups in Phaeosphaeriaceae. The type species of Amarenographium lacks sequence data, hence, we treat Amarenographium as polyphyletic in Pleosporales. Amarenographium ammophilae Wanasinghe, Camporesi, Wijayaw. & K.D.

Ztg. 10: 301 (1852); Fig. 25 Notes: Schlechtendal (1852) introduced Ampelomyces with A. quisqualis as the type species. This genus is well known as mycoparasites and used as biocontrol agents (Sztejnberg et al. 1989; Tsay and Tung 1991; Falk et al. 1995; Szentiványi and Kiss 2003). In their sequence analyses, de Gruyter et al. (2009) and Aveskamp et al. (2010) showed Ampelomyces quisqualis grouped in Phaeosphaeriaceae. Phookamsak et al. (2014) and Wijayawardene et al. (2014c) also confirmed this familial placement and our sequence analyses also agree with their findings (Fig. 9). Angiopomopsis Hohn, Sber. Akad. Wiss.

However, Apiculospora has a conspicuous apiculus and guttulate conidia, while Placodiplodia lacks these characters. In sequence analyses, Apiculospora spartii clusters in Helotiales incertae sedis (Fig. 9). Apiculospora spartii Wijayaw., W.J. Li, Camporesi, A.J.L. Phillips & K.D. Hyde, sp nov.

Conidia ellipsoidal to subcylindrical, with rounded ends, aseptate, dark brown, occasionally guttulate, verrucose, thick-walled (Sutton 1980; Damm et al. 2007b; Slippers et al. 2013). Type species: Aplosporella chlorostroma Speg., Anal. Soc. cient. argent. 10(5–6): 158 (1880) Notes: The genus Aplosporella was introduced by Spegazzini (1880) with A. chlorostroma as the type species. Over 350 names are given in this genus in Index Fungorum (2016), but these names are mostly based on the host on which they occur (Damm et al. 2007b). Crous et al. (2006a), Schoch et al. (2006), Damm et al. (2007b) and Liu et al. (2012) treated Aplosporella as a genus in Botryosphaeriaceae. However, Slippers et al. (2013) introduced a new family, Aplosporellaceae to accommodate Aplosporella and Bagnisiella as they group in a distinct clade in Botryosphaeriales. Wijayawardene et al. (2014c) also confirmed this placement and accepted Aplosporellaceae as a distinct family in Botryosphaeriales. Our sequence analyses (Fig. 9) also confirm the placement of Aplosporellaceae in Botryosphaeriales. Apoharknessia Crous & S.J. Lee, Stud.

(2012e) showed both genera reside in Diaporthales, but Apoharknessia is placed between Pseudovalsaceae and Diaporthaceae. Our sequence analyses also show that Apoharknessia is phylogenetically distinct from Harknessia sensu stricto and resides as Diaporthales, genera incertae sedis (Fig. 12).

Asexual morph: Conidiomata stromatic, subepidermal to immersed, solitary to gregarious, subglobose to irregular, unilocular, pale brown. Conidiomata wall outer layer composed of thin-walled, pale brown cells of textura angularis, inner layer pale yellow to hyaline. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lageniform to ampulliform, hyaline, smooth, invested in mucus. Conidia conical, aseptate, brown, with a longitudinal band on the flat surface, thick and smooth-walled, guttulate, with short hyaline apiculus; with small globule of mucus on base (description modified from Nag Raj 1993 as Harknessia insueta). Type species: Apoharknessia insueta (B. Sutton) Crous & S.J. Lee, Stud. Mycol. 50(1): 240 (2004); Fig. 30 ≡ Harknessia insueta B. Sutton, Mycol. Pap. 123: 20 (1971) Notes: The genus Apoharknessia was introduced to accommodate Harknessia insueta as it clustered in a distinct phylogenetic lineage to Harknessia sensu stricto (Lee et al. 2004). In conidiogenesis and conidial morphology, Apoharknessia is similar to Harknessia, but it differs in culture characteristics and in phylogenetic analyses. In culture, Apoharknessia does not produce ‘fluffy aerial mycelium, but colonizes the agar by growing within the medium’ and sporulates much earlier than species of Harknessia (Lee et al. 2004). Lee et al. (2004) also observed that Apoharknessia forms conidia directly on hyphae, while Harknessia forms conidia in conidiomata. Apoharknessia however, is phylogenetically distinct from Harknessia sensu stricto (Lee et al. 2004; Crous et al. 2012e).

Coelomycetous morph: Conidiomata acervuli, solitary to gregarious, immersed, erumpent at maturity, irregular, black, carbonaceous, coriaceous. Conidiomata basal stroma composed of dark brown to hyaline-walled cells of textura angularis, with thick side walls, thin at upper and lower walls. Setae absent, or rarely present. Conidiophores cylindrical, 1– 2-septate, verrucose, flexuous. Conidiogenous cells cylindrical, smooth or verrucose. Conidia globose to subglobose, dark brown, smooth-walled or with minute wall ornamentations, with a truncate basal scar (Crous and Groenewald 2013; Senanayake et al. 2015). Type species: Arthrinium caricicola Kunze & J.C. Schmidt, Mykologische Hefte (Leipzig) 1: 9 (1817) Notes: The genus Arthrinium was introduced by Schmidt and Kunze (1817) with A. caricicola as the type species, as a hyphomycetous genus (Kirk et al. 2008; Seifert et al. 2011). However, Senanayake et al. (2015) showed that a coelomycetous species, A. hyphopodii D.Q. Dai et al., with ‘globose to subglobose, dark brown conidia’ has phylogenetic lineage with Arthrinium in Apiosporaceae (Figs. 9 and 16). Crous and Groenewald (2013) treated Apiospora as the sexual morph of Arthrinium. Further, Crous and Groenewald (2013) reduced younger sexual typified name i.e. Apiospora under the older asexual typified name.

Karst., Hedwigia 23(1): 18 (1884) Notes: Petrak (1922) introduced Ascochytulina with A. deflectens as the type species. Sutton (1980) accepted only the type species and treated it as a close member of Pseudodiplodia and Stenocarpella. Evans and Punithalingam (1985) introduced A. pini-acicola H.C. Evans & Punith. and discussed the similarities between Ascochytulina and Pseudodiplodia. Punithalingam (1988) introduced A. smilacina Punith. thus genus comprises 3 species.

Members in this genus have mainly been recorded as endophytes from twigs of Alnus and Betula species in Betulaceae (Sutton 1980; Kowalski and Kehr 1996; Tanaka et al. 2010). Nine names are listed in Index Fungorum (2016) and eleven species epithets are listed in Robert et al. (2013). However, these records should be updated based on recent molecular results as Asterosporium shares close morphological features with Prosthemium (Kamiyama et al. 2009; Tanaka et al. 2010). Sutton (1980) accepted two species, viz. Asterosporium asterospermum and A. betulinum Peck in the genus. Two species have since been introduced A. attenuatum Murvan. & Dekan. and A. orientale Mel’nik. Asterosporium orientale and A. betulinum were shown to belong in Prosthemium, based on sequence analyses (Kamiyama et al. 2009; Tanaka et al. 2010). This confusion has occurred as both Asterosporium and Prosthemium share several morphological and ecological characters (Tanaka et al. 2010). Detailed taxonomic notes on Asterosporium and Prosthemium are provided under genus Prosthemium. Tanaka et al. (2010) showed that Asterosporium asterospermum belongs to Diaporthales, genera incertae sedis, the sexual morph was not determined. Our sequence analyses also agree with Tanaka et al.

Notes: Only Asterosporium attenuatum has been recorded from Acer spp. (from Acer campestris) (Sutton 1980; Ellis and Ellis 1985; Murvanishvili and Dekanoidze 1992; Farr and Rossman 2016; Index Fungorum 2016). The conidia of A. acerinum are similar in shape to those of A. attenuatum, but they are smaller (35–50 × 42–50 μm vs. 57–84 × 21–24 μm). The conidiophores of A. acerinum are also smaller, than those of A. attenuatum (60–80 × 5.6 μm vs. 15–35 × 2–4 μm). Several attempts of single conidial isolation were not successful.

Type species: Avettaea philippinensis Petr. & Syd., Beih. Rep. spec. nov. regn. veg. 42: 299 (1927) Notes: Petrak and Sydow (1927) introduced Avettaea with A. philippinensis as the type species. In morphology, Avettaea resembles Aplosporella and Sphaeropsis. Taxonomic key is provided under Sphaeropsis to distinguish Avettaea, Aplosporella and Sphaeropsis. Besides the type species, the genus comprises i.e. A. alcornii Sivan. & B. Sutton and A. salvadorae (Petr.) Abbas & B. Sutton (Sivanesan and Sutton 1985; Abbas and Sutton 1988a).

Type species: Bambusicola massarinia D.Q. Dai & K.D. Hyde, Cryptog. Mycol. 33(3): 370 (2012); Fig. 37 Notes: Dai et al. (2012) introduced Bambusicola with B. massarinia as the type species. Currently the genus comprises four species (Dai et al. 2012; Index Fungorum 2016). Sequence analyses of the genus showed distinct phylogenetic lineage in Pleosporales (Dai et al. 2012), thus Hyde et al.

Conidiophores meristematic, unbranched, straight, pale brown, smooth-walled. Conidiogenous cells holothallic, integrated, fragmenting. Conidia formed in long, unbranched, basipetal chains, muriform, globose, dark brown, smooth-walled (Rao and Rao 1964; Sutton 1980; Nag Raj and DiCosmo 1981b). Type species: Barnettella speciosa D. Rao & P. Rag. Rao, Mycopath. Mycol. appl. 22: 56 (1964); Fig. 39 Notes: Rao and Rao (1964) introduced Barnettella with B. speciosa as the type species. Subsequent studies by Rao (1970), Rao and Rao (1973) added two more species. Sutton Fungal Diversity (1977, 1980) accepted Barnettella as a coelomycetous genus and stated the conidiomata as ‘stromatic’, while the original descriptions noted them as ‘acervuli’. Further, Sutton (1980) stated, ‘the conidioma, is however, not typically acervular, for it is superficial, neither it really strictly sporodochial for there are certainly pseudolocular cavities in it’. Nag Raj and DiCosmo (1981) re-described the type species and accepted the conidiomata as stromatic. Barnettella is listed in Kirk et al. (2008), but it is not included in Kirk et al. (2013). We suggest this as a wellestablished genus and should be included in protected list of names. Barriopsis A.J.L.

Sexual morph: see Phillips et al. (2008, 2013); Doilom et al. (2015). Asexual morph: Conidiomata stromatic or pycnidial, solitary to gregarious, superficial to subepidermal, un- or multilocular, dark brown to black, ostiolate. Ostiole apapillate, central, circular. Paraphyses present or absent, if present, arising from the conidiogenous layer, extending above the level of developing conidia, thin-walled, hyaline, mostly aseptate. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic to phialidic, or proliferating at the apex, cylindrical, hyaline, thin and smooth-walled, forming periclinal thickenings. Conidia oval or cylindrical, both ends broadly rounded, thickwalled, initially hyaline, pale brown to brown, 0–3-septate, with longitudinal striations at maturity, smoothwalled. Chlamydospores present or absent, catenate, intercalary, brown, smooth and thick-walled, formed within the agar medium (Phillips et al. 2008, 2013; Abdollahzadeh et al. 2009; Doilom et al. 2014). Type species: Barriopsis fusca (N.E. Stevens) A.J.L. Phillips et al., Persoonia 21: 39 (2008) Notes: Phillips et al. (2008) introduced Barriopsis with B. fusca as the type species. Abdollahzadeh et al. (2009) introduced the first coelomycetous species in Barriopsis i.e. B. iraniana Abdollahz. et al. Doilom et al. (2014) introduced B. tectonae Doilom et al. with both sexual and asexual morphs. In morphology, Barriopsis resembles Lasiodiplodia as both genera has oval or cylindrical conidia with longitudinal striations. However, in Barriopsis the striations are visible on young, hyaline conidia, at least in B. iraniana. Nevertheless, both show distinct phylogenetic lineages in Botryosphaeriaceae (Phillips et al. 2008, 2013; Fig. 10). Bartalinia Tassi, Bulletin Labor. Orto Bot. de R. Univ.

Conidiomata wall outer layer composed of dark brown to black-walled cells of textura angularis, inner wall thin, hyaline. Conidiophores reduced to conidiogenous cells. Conidiogenous cells ampulliform, discrete, determinate, hyaline, smooth-walled, generated from inner layer of the pycnidium wall. Conidia subcylindrical, 4-septate, slightly constricted at the septa, smooth-walled, basal cell with truncate base, obconic, hyaline, bearing un-branched single appendage; 3 median cells subcylindrical, hyaline to pale brown; apical cell conical, almost hyaline, bearing appendage with 3 branches, attenuated, flexuous (Sutton 1980; Nag Raj 1993; Anderson and Bianchinotti 1996; Chi et al. 2002; Marincowitz et al. 2010; Senanayake et al. 2015). Type species: Bartalinia robillardoides Tassi, Bulletin Labor. Orto Bot. de R. Univ. Siena 3: 4 (1900); Fig. 41 Notes: Tassi (1900) introduced Bartalinia, with B. robillardoides as the type species. The genus comprises 19 species epithets (Index Fungorum 2016). Morgan-Jones et al. (1972a) carried out a partial taxonomic revision for Bartalinia and accepted only nine species. Morgan-Jones et al. (1972a) stated that conidiogenesis of Bartalinia is annellidic. Sutton (1980) also agreed with Morgan-Jones et al. (1972a) and further stated that genus shows ‘holoblastic, annellidic conidiogenesis’. At the same time Sutton (1980) mentioned that the genus needs taxonomic revision and described species must also be revised. Von Arx (1981) synonymized Bartalinia under Seimatosporium Corda but this redisposition was questioned and rejected by Nag Raj (1993). Furthermore, Nag Raj (1993) rejected the conidiogenesis process (i.e. annellidic) suggested Fungal Diversity by Morgan-Jones et al. (1972a) and mentioned it as ‘holoblastic’. In his generic revision, Nag Raj (1993) accepted only six species including the type species viz. Bartalinia bischofiae Nag Raj, B. lateripes (Ellis & Everh.) Nag Raj, B. laurina (Mont.) Nag Raj, B. pistacina (J.L. Maas) Nag Raj and B. tamarindi Nag Raj. Nag Raj (1993) listed another nine Fungal Diversity species which are not well described or with inadequate data and six species which have been described as Hyalotia Guba. (Nag Raj (1993) considered Hyalotia as a synonym of Bartalinia). Since the generic revision by Nag Raj (1993), five additional species have been described viz. Bartalinia ananatis Li Zeng et al. (Chi et al. 2002), B. dracaenae P.G. Xi et al. (Xi et al. 2000), B. goniolimonis Andrian. & Minter (Andrianova and Minter 2007), B. mellea F. Anderson & Bianchin. (Anderson and Bianchinotti 1996) and B. pondoensis Marincowitz et al. (Marincowitz et al. 2010) Based on morphological characters, Sutton (1980) grouped Bartalinia in the suborder Blastopycnidiineae (annellidic). However, this classification and not show a clear phylogenetic relationship and most other members of this suborder were not closely related to Bartalinia (Hyde et al. 2013; Wijayawardene et al. 2014d). Jeewon et al. (2003) and Jaklitsch and Voglmayr (2012) showed that Bartalinia has closer relationships with Pestalotiopsis, Seimatosporium and Seiridium which are accepted genera in Amphisphaeriaceae (Kirk et al. 2008; Wijayawardene et al. 2012a). However, Senanayake et al. (2015) found that Bartalinia showed a distinct phylogenetic lineage in Xylariomycetidae, Amphisphaeriales. Hence, Bartaliniaceae was introduced with Broomella, Hyalotiella and Truncatella as other members of the family (Senanayake et al. 2015). No sexual morphs are yet linked with Bartalinia (Sutton 1980; Nag Raj 1993; Wijayawardene et al. 2012a; Senanayake et al. 2015). Crous et al. (2014a) designated a lectotype and epitype of B. robillardoides. Bellulicauda B. Sutton, Can. J.

Nag Raj (1993) treated Bellulicauda as an appendage-bearing genus, but Sutton (1980) stated only that ‘remains of the conidiogenous cell attached’. Pereira et al. (2005) also provided detailed taxonomic notes and stated that conidia are with ‘unbranched frill’. Pereira et al. (2005) recorded B. dialii from Brazil and from Africa (Sierra Leone) and mentioned that the attempts to isolate the taxon were unsuccessful. Sequence data is unavailable thus taxonomic placement is uncertain. Bellulicauda sanguisorbae Wijayaw., Camporesi, McKenzie & K.D. Hyde, sp. nov.

Notes: Bellulicauda sanguisorbae has similar morphology to Bellulicauda in conidiogenesis and conidial characters although it does not have remains of the conidiogenous cell attached or an unbranched frill. Other conidial characters such as pigmentation, shape, lacking septa are similar to the type species. Thus, we introduce our collection as a new species in Bellulicauda. Fungal Diversity Fungal Diversity Notes: Swart (1988) introduced Blastacervulus with B. eucalypti as the type species. In conidiomata shape, Blastacervulus resembles Colletogloeopsis (= Teratosphaeria) however, conidia of the latter genus are not in a chain. Cheewangkoon et al. (2009) re-described B. eucalypti based on fresh collections and sequence analysis showed B. eucalypti groups with Alysidiella parasitica, Heteroconium eucalypti and H. kleinziense. However, Cheewangkoon et al. (2009) did not confirm a familia l plac ement. In our ph ylogenetic ana ly ses, Blastacervulus eucalypti clusters in Planistromellaceae (Fig. 9).

Type species: Bleptosporium montteae Speg. ex Steyaert, Darwiniana 12: 172 (1961) Notes: Steyaert (1961) introduced Bleptosporium, with B. montteae as the type species. Sutton (1963) introduced Bleptosporium pleurochaetum (Speg.) B. Sutton but Sutton (1980) and Nag Raj (1993) treated Bleptosporium as a monotypic genus. Von Arx (1981) listed Bleptosporium under Seimatosporium however, Nag Raj (1993) treated Bleptosporium as a distinct genus. Further, Nag Raj (1977b, 1993) stated Bleptosporium has an Amphisphaeria sexual morph (A. argentinensis Nag Raj) based on close association of both species. However, this link has not been proven by cultural or sequence studies. Moreover, the sequence data is unavailable thus, taxonomic placement is uncertain. Botryohypoxylon Samuels & J.D.

In this study we concentrate only on Dichomera as Fusicoccum has hyaline spores (Liu et al. 2012; Phillips et al. 2013). (However, Fusicoccum Corda was treated as a synonym of Botryosphaeria by Phillips et al. 2013) Cooke (1878) introduced Dichomera with D. saubinetii as the type species. There are 48 species epithets in Index Fungorum (2016), but some have been transferred to other genera, such as Camarosporium (Saccardo 1884). Funk and Sutton (1972) and Sutton (1975a) provided taxonomic notes and illustrations for Dichomera. Sutton (1980) compared Dichomera with Camarosporium and stated that ‘Dichomera, which has usually been interpreted as the stromatic analogue of Camarosporium Schulz.’ Butin (1993) examined the relationships between Camarosporium and Dichomera based on their substrates and types of conidiomata and agreed with Sutton (1980), who treated Dichomera as a stromatic form of Camarosporium. Butin (1993) examined oak-inhabiting Camarosporium sp. (C. oreades (Durieu & Mont.) Sacc.) and Dichomera sp. (D. saubinetii) to support his assumption and concluded that the former species represents the pycnidial form of the latter species. Butin (1993) also examined another type of coelomycetous taxon adjacent to the stromata of Dichomera saubinetii on bark of oak, but with hyaline, fusiform, one-celled conidia and identified it as Fusicoccum Fungal Diversity Fig. 43 Blastacervulus eucalypti (Material examined: Australia, Queensland, Blackall, Airport, on leaves of Eucalyptus eremophila, 22 September 1997, M.H.

Hence Butin (1993) predicted a relationship between fusicoccum-like taxa and dichomera-like taxa based on cultural techniques. Barber et al. (2005) observed dichomera-like conidia in the cultures of several Botryosphaeria spp. and this was Fungal Diversity species groups with Botryosphaeria sensu stricto (see under results of molecular data analyses).

(2013) did not consider Dichomera to be a synonym of Botryosphaeria as ex-type strains were not available. In our phylogenetic analyses (Figs. 10 and 13), dichomeralike taxa are scattered in the Botryosphaeriaceae and the type Fig. 45 Botryohypoxylon amazonense. a Macroconidiogenous cells with immature macroconidia. b Macroconidia. c Microconidiogenous cells and microconidia.

Notes: Farr and Rossman (2016) reported Dichomera saubinetii (conidial dimensions 11–13 × 7–10 μm fide Sutton 1980) from Quercus sp. However, our collection has longer conidia than D. saubinetii. Moreover, our new collection and the type species of Dichomera, D. saubinetii (CBS 990.70) group in Botryosphaeria sensu stricto. Hence our new collection is introduced as a new species in Botryosphaeria.

Sexual morph: see Li et al. (2015b); Senanayake et al. (2015). Asexual morph: Conidiomata stromatic, pycnidioid, scattered to gregarious, immersed to semi-immersed, rounded, oval or elongated, black, unilocular, papillate, glabrous. Conidiomata wall composed of thick-walled, brown cells of textura globulosa to textura angularis, outwardly pale brown to brown, inwardly merging with relatively thin-walled and colourless cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells cylindrical, phialidic, percurrently proliferating, discrete, hyaline, smooth. Conidia fusiform to aciculate, with acute ends, straight or slightly curved, 3-septate, constricted at septa, pale brown or brown, verruculose, thickwalled; bearing a single tubular appendage at each end, or 2–5 appendages at apex and a single appendage at the base (Li et al. 2015b; Senanayake et al. 2015). Type species: Broomella vitalbae (Berk. & Broome) Sacc., Syll. fung. (Abellini) 2: 558 (1883); Fig. 49 Notes: Saccardo (1883) introduced Broomella with B. vitalbae as the type species. Shoemaker et al. (1989) and Yuan and Zhao (1992) reported pestalotiod-like asexual morphs. Broomella spp. with truncatella-like asexual morphs are not congeneric with the type species of Broomella (Senanayake et al. 2015). Based on sequence data, Li et al. (2015) showed Broomella sensu stricto resides in Amphisphaeriaceae, and reported the asexual morph which has conidia with a single apical and basal appendages. However, Senanayake et al. (2015) treated Broomella as a distinct genus in Bartaliniaceae and this agrees with our phylogenetic sequence analyses (Figs. 9 and 16). Brunneodinemasporium Crous & R.F. Castañeda, Persoonia, Mol.

Type species: Brunneodinemasporium brasiliense Crous & R.F. Castañeda, Persoonia, Mol. Phyl. Evol. Fungi 28: 129 (2012); Fig. 50 Notes: Crous et al. (2012f) introduced Brunneodinemasporium with B. brasiliense and mentioned it has hyaline to pale brown conidia. Brunneodinemasporium morphologically resembles Dinemasporium which also has hyaline to pale brown, aseptate conidia (Sutton 1980; Nag Raj 1993), but is phylogenetically distinct from Dinemasporium sensu stricto (Crous et al. 2012f). Maharachchikumbura et al. (2015) listed Brunneodinemasporium under Chaetosphaeriaceae, Chaetosphaeriales. Our phylogenetic analyses, also agree with Maharachchikumbura et al. (2015) (Fig. 9). Caeruleoconidia Zhurb. & Diederich, Herzogia 28(2): 264 (2015) Facesoffungi number: FoF 01787; Fig. 51 Ascomycota, genera incertae sedis Lichenicolous. Sexual morph: Undetermined. Asexual morph: Conidiomata sporodochial to pulvinate, stromatic, erumpent, convex to applanate, black, but sometimes with a lateral ring-like rudimentary wall. Conidiophores reduced conidiogenous cells, hyaline to light greenish blue, densely aggregated in a compact basal stroma. Conidiogenous cells holoblastic, hardly distinguishable. Conidia subglobose to irregularly ellipsoid or rectangular, abundant, solitary to indistinctly catenate, subhyaline to moderate greenish blue becoming olivaceous green in KOH, dry, 0(−1)-septate, smoothwalled (Zhurbenko et al. 2015). Type species: Caeruleoconidia ochrolechiae Zhurb. & Diederich, Herzogia 28(2): 264; Fig. 51 Notes: Zhurbenko et al. (2015) introduced Caeruleoconidia with C. ochrolechiae as the type species. Caeruleoconidia ochrolechiae resembles Coniambigua phaeographidis, but the latter has pycnidial-like conidiomata with a colourless wall, and dark brown, aseptate conidia with a thin and ornamented outer wall (Zhurbenko et al. 2015). The taxonomic key under Lichenoconium allows distinguishing Caeruleoconidia from other lichenicolous genera. Sequence data is unavailable, thus taxonomic placement is uncertain. Conidiomata of Caeruleoconidia resemble sporodochia and might therefore be referred to as hyphomycetes. However, as these sporodochia-like structures are often surrounded by a thin rudimentary wall, Caeruleoconidia may as well be treated as a coelomycetous genus.

Type species: Callistospora gaubae Petr., Sydowia 9(1–6): 571 (1955); Fig. 52 Notes: Petrak (1955a) introduced Callistospora with C. gaubae as the type species. However, Sutton (1980) did not include this genus in his monograph. von Arx and Constantinescu (1983) re-described the genus, but with several omissions (viz. did not mention the presence of mucoid appendages of conidia, mucus in conidiophores and presence of microconidia), thus Nag Raj (1989, 1993) remedied these omissions and provided detailed taxonomic notes. Callistospora is a monotypic genus and sequence data is unavailable, thus its taxonomic placement is uncertain. Camarographium Bubák, Ber. dt. bot.

Grove (1937) included C. metableticum (Trail) Grove and C. abietis (Wils. & Anders.) Grove in the genus, but Sutton (1980) questioned the placement of these two species in Camarographium as their conidiomata structures are not congeneric with the type species. Verkley et al.

Notes: The distoseptate conidia of Camarographium species separate them from camarosporium-like taxa. Based on morphology (Sutton 1980), we conclude our collection is properly placed in Camarographium. Our collection has wide conidia and is morphologically distinct from other described species (Crous et al. 2011b) and it is thus introduced as a new species. Single spore isolation of Camarographium clematidis was successful, but germinated conidia did not grow further in PDA or MEA. In morphology, Camarographium clematidis resembles with Magnicamarosporium iriomotense, the type species of Magnicamarosporium (Tanaka et al. 2015) however, our collection lacks paraphyses.

Conidiogenous cells holoblastic, annellidic, integrated to discrete, doliiform, lageniform or cylindrical, smooth, hyaline, formed from the inner cells of the pycnidial wall. Conidia variable in shape, mostly ellipsoidal, curved to straight, truncate at the base, obtuse at the apex, muriform, continuous or constricted at the septa, medium brown to dark brown, thin and smoothwalled (Mirza 1968; Sutton and Pollack 1974; Sutton 1980; Hyde et al. 2013; Wijayawardene et al. 2014b; Tibpromma et al. 2015). Type species: Camarosporium quaternatum (Hazsl.) Schulz., Verh. Zool.-Bot. Ges. Wien 20: 641 (1870) Notes: The genus Camarosporium was introduced by Schulzer (1870) with C. quaternatum as the type species. There are approximately 500 records listed in Index Fungorum (2016), but most of them have not been reexamined since they were introduced (Sutton 1980). Camarosporium was treated as a polyphyletic genus (Sutton 1980; Kirk et al. 2008; Wijayawardene et al. 2012b) and linked to several phylogenetically distinct families viz. Leptosphaeriaceae (Schoch et al. 2009), Cucurbitariaceae (Doilom et al. 2013) and Botryosphaeriales, genera incertae sedis (Liu et al. 2012). However, Wijayawardene et al. (2014a) showed that Camarosporium sensu stricto belongs to Pleosporineae, Pleosporales and predicts its placement as a new family. Wijayawardene et al. (2014a) and Tibpromma et al. (2015) showed that Camarosporium sensu stricto has cucurbitaria-like sexual morphs.

Petr., Sydowia 8 (1–6): 97 (1954) Notes: Petrak (1954) introduced Camarosporula to accommodate the asexual morph of Anthracostroma. Sutton (1980) Fungal Diversity provided a description and illustrations of the type species and accepted A. persooniae as the sexual morph. Crous et al. (2011d) phylogenetically confirmed this established link. Hence, Wijayawardene et al. (2014c) proposed to synonymize the younger asexual typified name under older sexual typified name. However, Rossman et al. (2015) contrary with Wijayawardene et al. (2014c) suggested to adopt Camarosporula over Anthracostroma as former has been reported frequently (Farr and Rossman 2016) and as it was used in recent literature (Crous et al. 2011d). I n m o r p h o l o g y, C a m a r o s p o r u l a r e s e m b l e s camarosporium-like taxa, but it is phylogenetically quite distinct and is accommodated in Teratosphaeriaceae (Crous et al. 2011d; Figs. 9 and 11).

C. leptaleum (Petr.) Petr., C. macarangae (Petr.) Petr., C. stylosporum (Cooke) Petr. and C. trematis (Syd.) Petr. Arnaud (1918) and Farr (1973) re-described the genus and Sutton (1980) accepted 12 species. Wijayawardene et al. (2012b) and Dai et al. (2014a) treated Capnodiastrum as a genus in Englerulaceae and stated it is the asexual morph of Englerula. Sequence data is unavailable, thus taxonomic placement of Capnodiastrum is uncertain.

Type species: Carnegieispora rimeliae Etayo & F. Berger, Opuscula Philolichenum 7: 18 (2009); Fig. 60 Notes: Etayo and Berger (2009) introduced Carnegieispora with C. rimeliae as the type species. Carnegieispora shows distinct conidial morphological characters as it has digitate (finger-like) conidia, and therefore clearly differs from other common lichenicolous genera such as Lichenoconium or Lichenodiplis, which have obvate, obpyriform, ellipsoid to sub-sphaerical (Hawksworth 1977) or subcylindrical to cylindrical conidia, respectively (Hawksworth and Dyko 1979). A taxonomic key to distinguish lichenicolous taxa is provided under the notes of Lichenoconium. The genus is monotypic and sequence data is unavailable. Thus, taxonomic placement is uncertain.

Type species: Ceratopycnis clematidis Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 124: 88 (1915) Notes: Von Höhnel (1915) introduced the genus Ceratopycnis with C. clematidis as the type species. Morgan-Jones et al. (1972c), Morgan-Jones (1975) and Sutton (1980) revisited the type species. Sutton (1980) mentioned that the two other species introduced by Racovitza (1959) (viz. C. bryophila Racov. and C. muscorum Racov.) are not congeneric with the type species, and thus treated the genus as monotypic. During our collecting program in Italy, we found a specimen which is morphologically similar to Ceratopycnis, but differs from the type species and hence introduce it as a new species.

Conidia cylindrical to ellipsoid, obtuse at apex, occasionally truncate at base, 1-septate, with prominent septum, continuous or occasionally slightly constricted, pale brown, eguttulate or guttulate, thin and smooth-walled (Sutton 1980; Tiwari and Rai 2009). Type species: Chaetodiplodia caulina P. Karst., Hedwigia 23: 62 (1884); Fig. 62 Notes: Karsten (1884) introduced Chaetodiplodia with C. caulina as the type species. Currently, the genus comprises 27 epithets in Index Fungorum (2016) however, Sutton (1980) stated that the genus needs revision. van der Aa and van Kesteren (1979) treated the type species of Chaetodiplodia as a synonym of Ascochyta caulina (P. Karst.) Aa & Kesteren which is followed in Species Fungorum. De Gruyter et al. (2009, 2013) included two Chaetodiplodia strains (CBS 568.88, CBS 453.68) and two Ascochyta caulina strains (CBS 246.79, CBS 343.78) in their phylogenetic analyses. Chaetodiplodia sp. (CBS 568.88) clustered in Leptosphaeriaceae, while both Ascochyta caulina strains and Chaetodiplodia sp. (CBS 453.68) grouped in Pleosporaceae. De Gruyter et al. (2013) treated Ascochyta caulina as a synonym of Pleospora calvescens (Fr.) Tul. & C. Tul. following de Gruyter et al. (2009) who stated that the former species is the asexual morph of the latter. van der Aa and van Kesteren (1979) mentioned Ascochyta caulina has ‘sub-hyaline to yellowishgreen, olivaceous or rarely brownish’ conidia, thus contradicting with the generic concept of Ascochyta sensu stricto, which has hyaline conidia (Sutton 1980). Furthermore, Ascochyta sensu stricto belongs in Didymellaceae (de Gruyter et al. 2009, 2013; Wijayawardene et al. 2014d) and we assume Chaetodiplodia caulina as the most appropriate name for this taxon. Thus, based on current morphological and sequence data analyses, the type species of Chaetodiplodia caulina remains a synonym of Pleospora calvescens (de Gruyter et al. 2013). De Gruyter et al. (2013) mentioned that ‘Phoma betae clearly groups with other pycnidial fungi pathogenic on Chenopodiaceae, including Ascochyta obiones, A. hyalospora and A. caulina and Chaetodiplodia sp. All species produce similar hairy pycnidia, but are classified in Ascochyta or Coniothyrium due to conidial septation, or brown pigmentation of conidia, respectively’, based on their observations and sequence data analyses. P.W. Crous (personal communication) mentioned that the strain based on CBS 453.68 is not similar to Chaetodiplodia and hence it should be placed in a new genus. Therefore, naming this group of taxa based on names in GenBank is not wise. Further fresh collections and morpho-molecular analyses are essential to clarify the generic concept of Chaetodiplodia.

Nat., Bot., sér. 2 6: 338 (1836) Notes: Fries (1825) introduced Cheirospora with C. botryospora (Mont.) Berk. & Br. as the type species. Currently, nine epithets are listed in Index Fungorum (2016). However, two names have been transferred to Endobotryella and Taeniolella (Von Höhnel 1909; Hughes 1958). Sutton (1980) stated that ‘the several generic synonyms and wide spread occurrence on many different substrates of the described species has resulted in many nomenclatural changes and synonyms’. Thus it is essential to epitypify the genus and deposit ex-type strains in GenBank. Shabunin (2007) introduced Cheirospora alni Shabunin as a new species, while C. botryospora has been reported by several authors (Dennis 1986; Ginns 1986; Mel’nik and Popushoi 1992; Chlebicki 2002; Mulenko et al. 2004, 2008; Ono and Kobayashi 2005; Chlebicki and Chmiel 2006; Huseyin and Selcuk 2007; Kobayashi 2007; Legon 2012).

Chithramia has distinct conidia, bearing 6–8 unbranched appendages ‘which arise as extrusions through pores in the wall’ (Nag Raj 1993). Neoheteroceras also has appendages similar to Chithramia, but conidia in the former genus are falcate or oblong or fusiform. Kirk et al.

Conidia cylindrical or subfusiform, straight or slightly curved, 3-septate, continuous or constricted, two median cells very pale brown, end cells hyaline, thin-walled, basal cell with an eccentric, short, cellular appendage, apical cell with one ± straight and one lateral cellular, unbranched appendage (Sutton 1980; Nag Raj 1993; Allegrucci et al. 2011; Tangthirasunun et al. 2015). Type species: Ciliochorella mangiferae Syd., Annls mycol. 33(1/2): 63 (1935) Notes: Sydow and Mitter (1935) introduced Ciliochorella with C. mangiferae as the type species. Currently, there are seven records listed in Index Fungorum (2016). However, Allegrucci et al. (2011) accepted only four species including the type viz. C. buxifoliae Allegr. et al., C. castaneae Munjal and C. splendida Nag Raj & R.F. Castañeda. Endo et al. (2011) showed Ciliochorella castaneae grouped in Amphisphaeriaceae. However, Senanayake et al. (2015) found Ciliochorella clusters in Pestalotiopsidaceae with five other genera. Our multi-gene analyses (Figs. 9 and 16), agree with the findings in Senanayake et al. (2015). Cirrosporium S.

(2015) showed it groups with one of their new strains and introduced it as a new genus, Coelodictyosporium. In conidial morphology, Coelodictyosporium resembles Psammina (Sutton 1980), but Psammina was treated as hyphomycetous by Earland-Bennett and Hawksworth (1999, 2005), although Sutton (1980) treated Psammina as coelomycetous (see notes under Psammina).

Conidiomata wall composed of thin-walled, pale brown to hyaline cells of textura angularis. Conidiophores cylindrical or slightly irregular, short, sparsely branched, mostly at the base, hyaline or very pale brown, septate, smooth.

Ahmad, Sydowia 7(1–4): 269 (1953) = Colletogloeum dalbergiae (S. Ahmad) Petr., Sydowia 7(5–6): 369 (1953) Table 3 Conidial pigmentation of Colletogloeum spp Notes: Petrak (1953a) introduced Colletogloeum with C. dalbergiae as the type species. However, Sutton (1964) recognized that the earlier described Cercospora sissoo Syd. belongs to Colletogloeum and its conidia are similar in morphology to those of C. dalbergiae. Thus, Sutton transferred Cercospora sissoo to Colletogloeum and introduced the new combination, Colletogloeum sissoo. Ahmad and Lodhi (1953) (as Septogloeum dalbergiae) and Petrak (1953a) mentioned Colletogloeum dalbergiae has hyaline conidia, but Sutton (1964, 1980) stated that Colletogloeum sissoo has hyaline or very pale brown conidia. Subsequently introduced species by Pollack and Sutton (1972), Sutton (1975a, 1980), Sutton and Mehrotra (1982), Sutton and Swart (1986) were described with pale brown to medium brown conidia. Conidial pigmentation of known species of Colletogloeum spp. are summarized in Table 3. Crous et al. (2009b) stated that the taxonomic placement of Colletogloeum is confused as some species show relationships with Teratosphaeria, while ITS sequence data from the type species (C. sissoo IMI 119162) show it is allied with Pseudocercospora complex in the Mycosphaerellaceae. The genus needs to be resolved and generic boundaries must be established by using molecular data. In GenBank, there are only 10 sequences available, but none are identified to species level. We used two strains in our phylogenetic analyses (Fig. 11) and both strains reside in Mycosphaerellaceae. However, Crous et al.

Sutton (1974) re-described the type species and it was accepted by Swart (1986). Furthermore, Swart (1986) established Ascocoma Swart as the sexual morph of Coma, based on co-occurrence of both morphs on same host material. Beilharz and Pascoe (2005) also accepted this relationship by observing several fresh collections. Hence, Johnston et al. (2014) proposed to adopt Coma over Ascocoma in their list of recommended generic names for use in Leotiomycetes (Ascomycota).

Etayo and Diederich (1995) stated that mature conidiomata lack conidiogenous cells, but immature stages show hyaline structures which are variable in form and treated as conidiogenous cells. The genus remains monotypic and sequence data is unavailable. Thus taxonomic placement is uncertain. Coniella Höhn., Ber. dt. bot.

Conidiomata wall composed of medium brown-walled cells of textura angularis. Conidiophores densely aggregated, slender, subulate, simple, frequently branched above, reduced to conidiogenous cells, or with 1–2 supporting cells. Conidiogenous cells simple, tapering, hyaline, smooth, wide at apex, surrounded by a gelatinous coating, apex with visible periclinal thickening, rarely with percurrent proliferation. Conidia ellipsoidal, apex obtuse, base subtruncate, inequilateral, multi-guttulate when young, bi-guttulate when mature, hyaline to pale brown, becoming dark brown at maturity, smooth, germ slits present or absent; small, hyaline, mucoid basal appendage frequently present. Microconidia also rarely observed, cylindrical, hyaline, straight with obtuse ends (Sutton 1980; Nag Raj 1993; van Niekerk et al. 2004). Type species: Coniella pulchella Höhn., Ber. dt. bot. Ges. 36: 316 (1918) Notes: Von Höhnel (1917) introduced Coniella with C. pulchella as the type species. The genus has been re- visited by von Arx (1981) who used pigmentation of conidia as a criterion to distinguish Pilidiella from Coniella. However, Sutton (1980) and Nag Raj (1993) treated Pilidiella as a synonym of Coniella. Nevertheless, recent molecular based analyses confirmed that Pilidiella and Coniella have two distinct phylogenetic lineages in Schizoparmeaceae, Diaporthales (Castlebury et al. 2002; van Niekerk et al. 2004; Rossman et al. 2007; Fig. 12). Detailed taxonomic notes are provided for both Coniella and Pilidiella under Pilidiella. Coniothyrium Corda, Icon. fung.

Ostiole papillate, circular, central. Conidiomata wall thin, composed of thick-walled, brown cells of textura angularis or globulosa. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, annellidic, indeterminate, discrete, doliiform or ampulliform, hyaline or pale brown, smooth, formed from the inner cells of the pycnidial wall. Conidia elliptical or broadly clavate, apex obtuse, base truncate, cylindrical, sphaerical, 0–1-septate, constricted at the septum, hyaline to brown, thin, smooth-walled, or verruculose (Sutton 1980; Taylor and Crous 2001; Crous et al. 2013; de Gruyter et al. 2013). Type species: Coniothyrium palmarum Corda, Icon. fung. (Prague) 4: 38 (1840) Notes: The genus Coniothyrium was introduced by Corda (1840) with C. palmarum as the type species. Approximately 900 records have been listed in Index Fungorum (2016), but their accuracy is uncertain. Most of the introduced species are based on host and most of the described species lack cultural studies or molecular data (Verkley et al. 2004). De Gruyter et al. (2013) showed that several phoma-like taxa cluster with Coniothyrium sensu stricto hence treated them as Coniothyrium spp. Taxonomists have faced difficulties identifying coniothyrium-like taxa such as Coniothyrium, Cyclothyrium, Cytoplea and Microsphaeropsis (Sutton 1971a, 1980; Verkley et al. 2004, 2014; Damm et al. 2008; de Gruyter et al. 2013). Coniothyrium and Microsphaeropsis share similar morphological characters, thus Sutton (1971a) mentioned that ‘the majority of species described in Coniothyrium were not congeneric with the type species’.

Conidia narrow to broadly fusiform, straight or curved, transversely distoseptate, truncate at the base, rounded at the apex, apical and median cells brown to pale brown, 2–3 basal cells hyaline, guttulate, smooth-walled (Sutton 1975a, 1980; Orsenigo et al. 1998). Type species: Coryneum umbonatum Nees, Syst. Pilze (Würzburg): 34 (1816) [1816–17] Notes: Nees von Esenbeck (1817) introduced Coryneum with C. umbonatum Nees. as the type species. Currently more than 200 names are listed in Index Fungorum (2016). Sutton (1975a) accepted only 19 species and one variety under Coryneum sensu stricto in his monograph of Coryneum and related fungi. Subsequently, Sutton (1986) accepted an addition species, Coryneum terrophilum (Goos & E.F. Morris) B. Sutton. Sutton (1980) grouped Coryneum in suborder Blastostromatineae (Annellidic) based on morphology and conidiogenesis. However, this genus have not been treated by modern sequence based techniques and there are no sequences in GenBank. During our re-collecting programs, we collected one Coryneum sp. but isolation process based on single spore method was not successful. Coryneum pruni Wijayaw., Camporesi, McKenzie & K.D.

Lectotype species: Cyclothyrium juglandis (Schum. ex Rabenh.) Sutton (syn.

Sutton (1977, 1980) rejected this concept and further Sutton (1977) designated the lectotype. Sutton (1980) stated that Cyclothyrium juglandis is the asexual morph of Thyridaria rubronotata (Berk. & Br.) Sacc. However, the latter species is not the type species of Thyridaria thus Wijayawardene et al. (2014c) concluded that Cyclothyrium has thyridaria-like sexual morphs. Verkley et al. (2004), Damm et al. (2008) and de Gruyter et al. (2013) showed its taxonomic placement in Pleosporales by analysis of SSU sequence data. Our phylogenetic analyses also agree with results in Verkley et al. (2004) and de Gruyter et al. (2013). However, Thyridaria / Cyclothyrium clade does not belong in Massarineae or Pleosporineae (Fig. 9).

Veneto Sci. lett., ed Arti, Sér. 6 3: 307 (1885) Notes: Bizzozero (1885) introduced Cytoplea with C. arundinicola. However, Petrak and Sydow (1927) transferred Coniothyrium arundinaceum to Cytoplea as C. arundinacea. Sutton (1980) recognized the oldest taxon, Cytoplea arundinacea as the type species and listed Cytoplea arundinicola as a synonym of former species. Verkley et al. (2004) also accepted Cytoplea arundinacea as the type Fungal Diversity species of Cytoplea. A key is provided under Coniothyrium to distinguish Cytoplea and related genera. Based on culture methods, Hyde et al. (1996) revealed that Roussoella hysterioides (Ces.) Höhn. has asexual morphs in Cytoplea (viz. C. hysterioides K.D. Hyde). Kang et al. (1998) and Verkley et al. (2004) showed that Roussoella hysterioides and Cytoplea hysterioides have close relationship based on sequence data. Hence, Liu et al. (2014) listed Cytoplea as a synonym of Roussoella. However, Wijayawardene et al. (2014c) did not agree with Liu et al. (2014) as the sequences of type species of Cytoplea is unavailable. Thus, Wijayawardene et al. (2014c) proposed continued use of Cytoplea and Roussoella. Davisoniella H.J. Swart, Trans. Br. mycol.

Swart, Trans. Br. mycol. Soc. 90(2): 289 (1988); Fig. 80 Notes: Swart (1988) introduced Davisoniella with D. eucalypti which was found on leaf spots of saplings and on the foliage of recently felled trees. Swart (1988) compared Davisoniella with Coniothyrium and doubted former as stromatic counterpart of latter. However, Swart (1988) established Davisoniella as previous studies did not mention about stromatic states of Coniothyrium. In morphology, Davisoniella can be placed in Colletogloeopsis (current name Teratosphaeria) which also has ‘medium brown, aseptate conidia’ (Crous and Wingfield 1997). Colletogloeopsis spp. have been reported as pathogens of Eucalyptus spp. (Crous and Wingfield 1997; Cortinas et al. 2006) Hence, we doubt whether Davisoniella belongs in Teratosphaeria sensu stricto, however, this must be confirmed based on sequence data analyses.

Notes: Our strain is a camarosporium-like taxon (MFLUCC 14–0241) that groups in Didymellaceae and does not cluster with other species (Fig. 9). Currently there are no camarosporium-like taxa reported in Didymellaceae (Wijayawardene et al. 2014c), thus we introduce Didymellocamarosporium.

Notes: Four Camarosporium spp. are recorded on Tamarix species, viz. C. tamaricis Hollós on branches of Tamarix africanae (18–24 × 8–10 μm fide Hollós 1906), C. potebniae Sacc. & Trotter (28 × 12 μm fide Saccardo and Trotter 1913) on branches of Tamarix gallicae, C. tamaricum Mekht. (7– 21 × 7–17 μm) on branches of Tamarix hohenackeri and an unidentified Camarosporium species from Tamarix sp. (Farr and Rossman 2016). Our collection is morphologically distinct from these species of Tamarix and phylogenetic analyses show it belongs in Didymellaceae. Hence, Didymellocamarosporium is introduced to accommodate our new collection. Didymosporina Höhn., Sber. Akad. Wiss. Wien, Math.naturw.

Lév., Annls Sci. Nat., Bot., sér. 3 5: 274 (1846) For additional synonyms see Sutton (1980), Nag Raj (1993) and Crous et al. (2012f). Notes: Léveillé (1846) introduced Dinemasporium with D. graminum as the type species. However, Saccardo (1881) introduced D. strigosum (≡ Dematium aureum var. strigosum), thus Sutton (1980) treated D. strigosum as the type species as it is the oldest name. This was accepted by Nag Raj (1993) and Crous et al. (2012f). Sutton (1980) and Nag Raj (1993) stated that Dinemasporium has ‘hyaline or pale brown conidia’ but only Dinemasporium aberrans B. Sutton (Sutton 1969b) has been listed with pale brown conidia (Duan et al. 2007). There have been several species published since Sutton (1980), but all species have hyaline conidia (Matsushima 1995; Duan et al. 2007; Crous et al. 2012f, 2014c; Hashimoto et al. 2015). Hence, we conclude that the Fungal Diversity Fig. 84 Dinemasporium nelloi (Material examined: Italy, Province of Forlì-Cesena [FC], Castrocaro Terme, Converselle, on dead stem of Dactylis glomerata, 1 December 2012, E.

Scale bars: d = 100 μm, e = 50 μm, f–l = 10 μm. (Dinemasporium nelloi has hyaline conidia but we illustrate it to show other morphological characters) generic concept of Dinemasporium must be revised and probably it can be heterogeneous as predicted by Sutton (1980). Moreover, Crous et al. (2012f) showed that dinemasporiumlike taxa are polyphyletic in Chaetosphaeriaceae, Chaetosphaeriales, hence introduced Brunneodinemasporium. Maharachchikumbura et al. (2015) also accepted Dinemasporium as a distinct genus in Chaetosphaeriaceae, Chaetosphaeriales. et al. (2013). Asexual morph: Conidiomata pycnidial, solitary to gregarious, occasionally confluent, formed in uni- or multi-loculate stromata, immersed, becoming erumpent at maturity, ostiolate. Ostiole papillate, central, circular. Conidiomata wall thick, composed of thick-walled, brown cells of textura angularis; inner layer thin, hyaline. Conidiophores usually reduced to conidiogenous cells, when present hyaline, simple, occasionally septate, rarely branched, cylindrical, arising from the cells lining the pycnidial cavity. Conidiogenous cells holoblastic, hyaline, cylindrical, discrete or occasionally integrated, determinate or proliferating at the same level giving rise to periclinal thickenings, or proliferating percurrently and forming two or three annellations.

Scale bars: b, c = 300 μm, d–f = 30 μm, g–j = 20 μm Notes: Montagne (1834) introduced Diplodia with D. mutila as the type species. However, Montagne (1834) indicated Sphaeria mutila as the type of the new genus Diplodia, the 1834 protologue did not make any definite association of “mutila” with “Diplodia”, as required for a valid comb. nov. Therefore, the frequently cited date of 1834 for publication of the combination Diplodia mutila is incorrect. Fries (1823) described Sphaeria mutila and distributed two exsiccati under that name as Scler. Suec. 164 and 385. Stevens (1933) and Sutton (1980) reported that these two exsiccati in BPI and K had no spores. Alves et al. (2004) examined material of the same two exsiccati in STR and also found no spores. Montagne sent Fries a fungus that was identified as S. mutila. The record was listed under S. mutila Fr. by Montagne (1834) with the note that this would become the type of a new genus, Diplodia, later characterized by Fries (1849). Thus, the binomial Diplodia mutila was first introduced by Fries (1849). Montagne distributed this fungus in his exsiccatus No. 498. According to Alves et al. (2004) no material of this exsiccatus could be found in STR. Alves et al. (2004) examined Montagne’s specimen of D. mutila in Kew, K(M) 99664 (presumed to be an isotype) and found it to agree in all aspects with Stevens’ (1933) account of Montagne’s exs. 498. Stevens (1933) described Physalospora mutila as the sexual morph of D. mutila referring to BPI 599151, but this name was invalid because it lacked a Latin description. Alves et al. (2004) examined this specimen and could find no sexual morph, but they did find ample material of the sexual morph on BPI 599153, which is a specimen on apple collected by Stevens from the same locality at same time he collected BPI 599151. Shoemaker (1964) considered the sexual morph to be a species of Botryosphaeria and since the name B. mutila was already taken, he proposed the name Botryosphaeria stevensii. After Crous et al. (2006a) revised Botryosphaeria reducing it Fungal Diversity Fungal Diversity Fig. 86 Most parsimonious tree generated from the analysis of combined data set of ITS and EF1-α sequences of Diplodia species accepted in Phillips et al.

Ex-type strains are in bold and newly introduced species are in blue. The tree is rooted with Lasiodiplodia theobromae (CBS 164.96) to B. dothidea (Moug.) Ces. & De Not. and B. corticis (Demaree & Wilcox) Arx & E. Müll., the fungus known as B. stevensii was referred to only by its asexual name D. mutila. Some species of Diplodia, are known to be pathogens while others are recoded as endophytes and saprobes on a wide range of hosts and have a worldwide distribution (Sutton 1980; Crous et al. 2006a). Diplodia pinea, D. mutila, D. seriata are some important pathogens and other known pathogenic species are listed in Table 4. It is one of the largest genera among coelomycetous fungi and currently comprises more than 1200 names in Index Fungorum (2016). Traditionally, species in Diplodia were described based on host association, which resulted in proliferation of species names (Phillips et al. 2012). Slippers et al. (2004) rejected this concept and mentioned host association is not an important criterion in species differentiation of genera of Botryosphaeriaceae. Several species of Diplodia and Dothiorella share similar morphological characters, which can cause some confusion for taxonomists and pathologists. Slippers et al. (2013) showed that strains of Diplodia juglandis and D. coryli in GenBank grouped in Dothiorella sensu stricto. Thus Diplodia was restricted to taxa with uni- or multilocular conidiomata ‘lined with conidiogenous cells that form hyaline, aseptate, thickwalled conidia at their tips’ (Phillips et al. 2005, 2012). Further, Phillips et al. (2005) mentioned that most of the known Diplodia spp. have hyaline conidia for a long period, before they turn brown and 1-septate. However, some species (D. pinea, D. scrobiculata and D. seriata) produce conidia which become pigmented before release from the pycnidia and typically remain aseptate (Phillips et al. 2005, 2012). Recent phylogenetic studies reveal and delimit generic boundaries between Diplodia and Dothiorella (Phillips et al. 2008, 2013; Liu et al. 2012; Slippers et al. 2013, 2014), which is an important distinction in plant pathology and plant Fig. 87 Diplodia huaxii (holotype). a Branches of Platanus sp. b Conidiomata on host material. c, d Vertical sections of conidiomata. e–g Different stages of conidiogenesis. h–n Conidia.

D. ditior Sacc. & Roum. (25–30 × 10–12 μm), D. fulvella Cooke (30 × 14 μm), D. myxosporioides Sacc. (22 × 15 μm) and D. platanicola Sacc. (16–20 × 8–11 μm). In phylogenetic analyses, our new strain groups as a sister clade to D. seriata (Fig. 86). The conidia of D. seriata (22–27 × 11.5–14.5 μm fide Phillips et al. 2013) are aseptate and wider than our collection, while in our collection conidia are 1-septate. Moreover, our collection is morphologically distinct from other species reported from Platanus spp. and hence, we introduce it as a new species of Diplodia. Diplodia pseudoplatani Wijayaw., A.J.L.

Phillips et al. (2013) treated D. pseudoseriata and D. alatafructa clade as an unresolved clade. However, in phylogenetic analyses, both species separate with moderate bootstrap values (Fig. 86). In conidial morphology, our collection is distinct from both D. pseudoseriata (25.5–26.5 × 11.5–12 μm fide Phillips et al. 2013) and D. alatafructa (21.5–25 × 10– 12.5 μm fide Phillips et al. 2013), thus the new species is proposed to accommodate our collection. Diplodia italica Wijayaw., A.J.L. Phillips, Camporesi & K.D. Hyde, sp. nov.

Culture characteristics: On PDA fast growing, attaining 3 cm in 4 days at 18 °C, white from above, greyish white from below, margin uneven, cottony, thick mycelium. Material examined: Italy, Arezzo [AR] Province, Papiano Stia, on dead branch of Crataegus sp. 11 May 2014, Erio Camporesi, IT 1863 (MFLU 15–3300, holotype), living cultures MFLUCC 14–1007, GUCC 1863. Notes: In phylogenetic analyses (Fig. 86), this new collection groups as the sister clade to Diplodia crataegicola which has close morphology with our collection (conidia 11–16 × 6– 10 μm). However, D. crataegicola has larger conidiogenous cells (10–22 μm × 4–6 μm), while our collection has comparatively smaller conidiogenous cells (4–12 × 3–5 μm). Hence, based on both morphological and phylogenetic analyses, we introduce a new species. Discosia Lib., Pl. crypt. Arduenna, fasc. (Liège) 4: no. 346 (1837) = Adisciso Kaz.

Conidia dorsiventral, straight or slightly curved, 3–4-transverse septate, tapered to a truncate base, apex obtuse, hyaline to pale brown, smoothwalled, apical and basal cells each with a subapical and suprabasal unbranched cellular appendage (Sutton 1980; Nag Raj 1993; Vanev 1995; Matsushima 1996; Tanaka et al. 2011; Crous et al. 2013; Senanayake et al. 2015). Type species: Discosia strobilina Lib., PI. Crypt. Ard. exs. 346 (1837) Notes: Libert (1837) introduced Discosia with D. strobilina as the type species. Subramanian and Reddy (1974) recognized four sections in Discosia, and five described species (D. strobilina Lib., D. vagans de Not., D. julia Speg., D. aquatica Fautr. and D. grammita Berk. & Curt.) based on conidial septation and size, and the varying proportional lengths of the conidial cells. However, Subramanian and Reddy (1974) did not examine the Fungal Diversity Fig. 90 Discosia pseudoceanothi (holotype). a Conidiomata on branch of Medicago sp. b, c Vertical sections of conidiomata. d–f Different stages of conidiogenesis. g–j Conidia. Scale bars: b, c = 150 μm, d = 20 μm, e, f = 10 μm, g–j = 20 μm type of D. artocreas (Sutton 1980), which is treated as the type species of Discosia in Index Fungorum (2016). Subramanian and Reddy (1974) treated D. theae Cavara, D. virginiana and D. himalayensis as synonyms of D. strobilina. Sutton (1980) agreed with the synonomies of Subramanian and Reddy (1974), but Nag Raj (1993) rejected this. Morphological characters between some species of Discosia and Seimatosporium (such as Discosia grammita Berk. & M.A. Curtis) are unclear and thus phylogenetic analyses are important to distinguish them (Tanaka et al. 2011). Jeewon et al. (2002) showed that Discosia and Seimatosporium are distinct clades in Amphisphaeriaceae, Xylariales based on LSU and ITS sequence data. Tanaka et al. (2011) carried out extensive molecular data analyses (based on LSU, ITS and βtubulin) on both Discosia and Seimatosporium and showed discosia-like taxa are polyphyletic in Amphisphaeriaceae as predicted by Sutton (1980) and Nag Raj (1993). Hence, Tanaka et al. (2011) introduced Immersidiscosia Kaz. Tanaka et al. based on I. eucalypti (Pat.) Kaz. Tanaka et al. which has similar morphological characters with Discosia sensu stricto except for its hyaline conidia. Furthermore, Tanaka et al. (2011) introduced the sexual morph of Discosia sensu stricto viz. Adisciso Kaz. Tanaka et al., but here in we treat Adisciso as a synonym of Discosia agreeing with the ‘one fungus one name’ concept (Hawksworth 2012). Senanayake et al. (2015) showed that Discosia sensu stricto groups with Adisciso, Discostroma, Sarcostroma and Seimatosporium as a distinct clade in Amphisphaeriales, and hence, introduced Discosiaceae Maharachch. & K.D. Hyde to accommodate these genera (Fig. 16). Discosia pseudoceanothi Wijayaw., Camporesi, D.J. Bhat & K.D. Hyde, sp. nov.

Notes: We compared our collection with other Discosia species in Nag Raj (1993), Crous et al. (2013) and Senanayake et al. (2015). Although Discosia pseudoceanothi morphologically resembles D. ceanothi (A.W. Ramaley) Nag Raj (conidial dimensions = 18–24 × 3–3.5 μm), the former has wider conidia, and thus we introduce a new species based on differences in morphology.

Nag Raj and Kendrick (1972a) re-described the type species and introduced D. mysorensis Nag Raj & W.B. Kendr. Nag Raj (1993) added a third species, D. saksenaensis (S.S. Singh) Nag Raj and only these three species are listed in Index Fungorum (2016). Kirk et al. (2008) stated Doliomyces belongs in Amphisphaeriaceae, but sequence data is unavailable. Thus its placement is uncertain. However, Senanayake et al. (2015) listed Doliomyces under Amphisphaeriales, genera incertae sedis. However, we prefer to keep Doliomyces as a member of Bartaliniaceae, as it shows closer morphologies with other genera of the family. Dothideodiplodia Murashk., Trudy Sibitsk. Inst. Sel’sk. Khoz.

Type species: Dothiorella pyrenophora Berk. ex Sacc., Michelia 2(no. 6): 5 (1880) Notes: Saccardo (1880) introduced the genus Dothiorella with D. pyrenophora as the type species. Currently, there are 375 names listed in Index Fungorum (2016), but it is essential to confirm their accuracy based on sequence data analyses. ‘It is Fungal Diversity likely that a number of other Diplodia species will similarly reside in Dothiorella or Spencermartinsia, or vice versa, given the confusion of these names in the past’ (Slippers et al. 2013). Based on sequence data analyses, several researchers have confirmed the placement of Dothiorella in Botryosphaeriaceae (Phillips et al. 2008, 2013; Liu et al. 2012; Slippers et al. 2013, 2014). Detailed background of taxonomy of Dothiorella was provided by Sutton (1977) and Crous and Palm (1999a). Crous and Palm (1999a) reduced Dothiorella under Diplodia based on morphology, but Phillips et al. (2005) and Crous et al. (2006a) treated Dothiorella as a distinct genus. Phillips et al. (2005) reported Botryosphaeria sarmentorum A.J.L. Phillips et al. and B. iberica A.J.L. Phillips et al. with Dothiorella asexual morphs. However, Phillips et al. (2013) showed that these species are not congeneric with Botryosphaeria sensu stricto and thus transferred them to Dothiorella sensu stricto based on sequence data analyses. Hence, it is confirmed that Dothiorella sensu stricto has botryosphaeria-like sexual morphs (Phillips et al. 2013; Slippers et al. 2013). Dwiroopa Subram. & Muthumary, Proc. Indian Acad. Sci., Pl.

Farr and Rossman (2003) re-described the type species and transferred Harknessia lythri to Dwiroopa as a new combination. In conidial morphology and conidiomata structure, Dwiroopa closely resembles Harknessia (Farr and Rossman 2001, 2003). However, Dwiroopa lacks basal appendages and has longitudinal slits on both sides of the conidia, while Harknessia may or may not have a basal appendage and has longitudinal slits on only one side of the conidia (Farr and Rossman 2003). Dwiroopa lacks sequence data, but Farr and Rossman (2003) placed it in Diaporthales as it is closely related to Harknessia.

The genus is monotypic (Sutton 1980; Index Fungorum 2016) and sequence data is unavailable in GenBank. Hence, taxonomic placement is uncertain. Endobotrya has conidial morphology similar to Cheirospora, Endobotryella and Myxocyclus. A taxonomic key is provided under Endobotryella to distinguish it from related genera.

Naturk. 23–24: 351 (1870) [1869–70] Notes: Von Höhnel (1909) introduced Endobotryella to accommodate Myriocephalum oblongum. In morphology, Endobotryella shares a similar morphology with Cheirospora, but the latter has acervular to sporodochial conidiomata, while Endobotryella has stromatic conidiomata (Sutton 1980). Sutton (1980) placed both genera in Blastostromatineae, Monoblastic along with Endobotrya and Myxocyclus. However, Endobotryella oblonga lacks sequence data, hence taxonomic placement is uncertain.

Notes: Our collection from Festuca sp. closely resembles Angiopomopsis, Endocoryneum and Hendersoniopsis. However, Angiopomopsis has 3-distoseptate conidia (Sutton 1980) and thus it is distinct from our collection which has eusepta. Conidia of Hendersoniopsis have 2–7 transverse septate, but our collection has dark brown septa which was treated as a distinct character in Endocoryneum (Sutton 1980). Thus we place our collection in Endocoryneum. In phylogenetic analyses, Endocoryneum festucae grouped in Didymellaceae (Fig. 9). Endomelanconiopsis E.I.

Endomelanconium also produces dark brown conidia with a protruding base and each bears longitudinal striations (Sutton 1980; Verkley and van der Aa 1997; Yanna et al. 1999). Currently, the genus comprises four species viz. E. nanum Gamundí & Aramb. (Gamundí and Arambarri 1983), E. microsporum Verkley & van der Aa (1997), E. phoenicicola Yanna et al. (1999) and the type species. Gamundí (1997) stated Austrocenangium Gamundí is the sexual morph of Endomelanconium based on cooccurrence of both fungi on the same host material.

Epithyrium to generic level and placed four species in Epithyrium viz. E. obscurum (Pass.) Sacc., E. populi (Oudem.) Sacc., E. innatum (P. Karst.) Sacc. and E. resinae. Sutton (1977) accepted Epithyrium as a distinct genus and Sutton (1980) provided comprehensive taxonomic notes on the genus. Kirk et al. (2013) did not list Epithyrium in the list of ‘protected generic names of fungi’. However, we suggest to include Epithyrium in the protected generic name list as it was shown to be a wellestablished genus (Sutton 1980; Hawksworth and Sherwood 1981; Kirk et al. 2008).

Fairmaniella leprosa has been reported as a pathogen in several plants, especially on Eucalyptus sp.

However, phylogenetically both taxa show distinct affiliations in Pleosporales (Thambugala et al. 2015; Fig. 14). Floricola viticola resembles Pseudohendersonia as both taxa have 3-septate conidia, without mucilaginous sheath. However, Pseudohendersonia sensu stricto lacks sequence data and under Pseudohendersonia we show Pseudohendersonia galiorum resides in Didymellaceae (Fig. 9).

Type species: Forliomyces uniseptata Phukhamsakda, Camporesi & K.D. Hyde (in press) Notes: Phukhamsakda et al. (2016) introduced Forliomyces with F. uniseptata as the type species. Forliomyces morphologically resembles Coniothyrium and Paraconiothyrium. However, in phylogenetic analyses, Forliomyces resides in Sporormiaceae, while Coniothyrium and Paraconiothyrium are accommodated in Coniothyriaceae and Didymosphaeriaceae respectively (Fig. 9). Moreover, Forliomyces is morphologically similar to Microdiplodia Allesch.

However, according to Sutton (1977, 1980) the validity of Microdiplodia is questionable (see under Fig. 105 Fuscostagonospora sasae (Material examined: Japan, Fukushima, Minamiaizu, Ose pond, on dead twigs of Sasa sp., 30 August 2003, N.

However, Petrak (1947b) found Leptothyrium bornmuelleri is the older epithet of Gaubaea insignis thus, it was transferred to Gaubaea as G. bornmuelleri and treated as the type species. Further, Gaubaea insignis was treated as a synonym of G. bornmuelleri. In morphology, Gaubaea is similar to Jubispora and Septoriella. A taxonomic key is provided under Jubispora to distinguish Gaubaea from other related genera. Currently Gaubaea comprises of a single species (i.e. G. rechingeri Speer fide Speer 1971), besides the type species. Sequence data is unavailable, thus the taxonomic placement is uncertain.

Gloeocoryneum is morphologically quite similar with Leptomelanconium, thus Morgan-Jones (1971) treated the former as a synonym of the latter genus. However, Sutton (1975a, 1977, 1980) recognized Gloeocoryneum as a distinct genus based on slight differences in conidiogenous cells and conidia viz. Gloeocoryneum has long conidiogenous cells, but lacks annellations, while Leptomelanconium has annellations. Further, the conidia of Leptomelanconium are 0–1-septate, while those of Gloeocoryneum are 2–5-septate.

(2008, 2013) followed Morgan-Jones (1971) and did not list Gloeocoryneum in the list of ‘protected generic names of fungi’. We prefer to follow Sutton (1975a, 1977, 1980) and Matsushima (1995) as there are significant morphological differences between Leptomelanconium and Gloeocoryneum. However, G. angamosense was introduced with sporodochial conidiomata (Matsushima 1995), which are accepted as the conidiomata of hyphomycetous genera (Kendrick and Nag Raj 1993; Seifert et al. 2011). Hence, treating G. angamosense as a coelomycetous species is doubtful.

However, Gordonomyces has erumpent conidiomata with a smooth, black outer wall and immature conidia enclosed in a mucoid sheath (Crous et al. 2011c), and thus morphologically distinct from Phaeophleospora and Kirramyces.

Sci., Paris 105: 473 (1887) Notes: Scribner and Viala (1887) introduced Greeneria with G. fuliginea as the type species. Punithalingam (1974) treated Phoma uvicola as the oldest name of G. fuliginea thus former species was introduced as a new species of Greeneria. At the same time, Punithalingam (1974) listed Greeneria fuliginea as a synonym of G. uvicola. This synonymy was accepted by Sutton (1977, 1980), who treated the genus as monotypic. Tangthirasunun et al. (2014) introduced a second species, Greeneria saprophytica N. Tangthirasunun et al. Greeneria uvicola has been reported as a pathogen of grapevine (Vitis vinifera) (Alfieri et al. 1984; Crous et al. 2000; Farr et al. 2001; Longland and Sutton 2008; Navarrete et al. 2009; Abreo et al. 2012; Samuelian et al. 2013). Samuelian et al. (2013) and Tangthirasunun et al. (2014) showed that Greeneria clusters in Diaporthales, genera incertae sedis in their phylogenetic analyses.

The genus was re-described and illustrated by Sutton (1969a), Morgan-Jones et al. (1972b) and Nag Raj (1993). Guba (1961) showed that Griphosphaerioma has Labridella asexual morph based on culture methods. Shoemaker (1963) also accepted this link. Jeewon et al. (2002) predicted that Labridella might have closer phylogenetic relationship with genera in Amphisphaeriaceae however, sequence data is unavailable. The genus remains monotypic. Maharachchikumbura et al. (2015) proposed to adopt the older sexual typified name i.e. Griphosphaerioma over the younger asexual typified name.

Type species: Harknessia eucalypti Cooke, Grevillea 9(no. 51): 85 (1881); Fig. 111 Notes: Cooke and Harkness (1881) introduced Harknessia with H. eucalypti as the type species. Sutton (1980) and Nag Raj (1993) revised the genus and provided comprehensive background including keys and illustrations. Members of Harknessia have been reported as saprobes (Lee et al. 2004; Marincowitz et al. 2008) and also from leaf spots (Crous et al. 1989b, 1993). Nag Raj and DiCosmo (1981) treated Cryptosporella as the sexual morph of Harknessia. Castlebury et al. (2002), Crous et al. (2012d) and Lee et al. (2004) showed the overview of Diaporthales in their phylogenetic analyses and accepted Wuestneia/ Harknessia as a distinct clade. Crous et al. (2012d) confirmed the findings of Castlebury et al. (2002) and introduced Harknessiaceae Crous to place Harknessia and wuestneia-like spp (Fig. 12). However, Rossman et al. (2007) listed Wuestneia xanthostroma (Mont.) J. Reid & C. Booth, type species of Wuestneia as a member in Cryphonectriaceae. Nevertheless, several Wuestneia species have been reported with Harknessia asexual morphs (Crous et al. 1993; Crous and Rogers 2001). Hence, Crous et al. (2012e) treated Harknessia sensu stricto as having wuestneia-like sexual morphs. Petrak (1947a) introduced Cymbothyrium based on C. sudans as the type species. Sutton (1980) re-illustrated and described the type species and mentioned that ‘Cymbothyrium is distinguished from Harknessia only by the clypeate stromata and non-persistent conidiogenous cells’. However, Nag Raj and DiCosmo (1984) and Nag Raj (1993) treated Cymbothyrium as a synonym of Harknessia. Nevertheless, Crous et al. (2012e) questioned the synonymy in Nag Raj and DiCosmo (1984) and Nag Raj (1993). We follow Nag Raj and DiCosmo (1984) and Nag Raj (1993) as both genera share very similar morphological characters, until phylogenetic studies resolve the taxonomic placement of Cymbothyrium.

Butler, Memoirs of the Dept. Agric. India, Bot. Ser. 6: 198 (1913); Fig. 112 Notes: Butler (1913) introduced Hendersonina with H. sacchari as the type species. In conidial morphology, Hendersonina somewhat resembles Stenocarpella which has ‘0-3-septate, continuous or constricted, cylindrical to fusiform, straight or bent conidia’ (Sutton 1980). However, the dark scar at each end of conidia is conspicuous character in Hendersonina thus it can be distinguished from Stenocarpella.

However, Vasant Rao and Sutton (1976) re-described the genus and treated Hoehneliella as a coelomycetous genus and Sutton (1977, 1980) and Nag Raj (1993) accepted it.

Agnihothrudu and Luke (1970) introduced H. subramanianii Agnihothr. & Luke, but Punithalingam (1969) transferred it to Hyalotiopsis Punith. (see notes under Hyalotiopsis for comparison). Nag Raj (1975) re-described the genus and introduced Hyalotiella orientalis Nag Raj. However, Nag Raj (1979) treated it as a synonym of H. americana (Speg.) Nag Raj (≡ Robillarda americana Speg.). Li et al. (2015) introduced Hyalotiella spartii hence, Hyalotiella comprises three species. Senanayake et al. (2015) showed that Hyalotiella groups in Bartaliniaceae, Xylariales and our phylogenetic analyses also agree with their findings (Fig. 16). Hyalotiopsis Punith., Mycol.

Sci. 71(2): 48 (1970) Notes: Punithalingam (1969) introduced Hyalotiopsis with H. subramanianii as the type species. Thaung (1975) introduced a second species, H. borassi Thaung, but it was transferred to a new genus, Parahyalotiopsis Nag Raj by Nag Raj (1976). Hence, Hyalotiopsis remains a monotypic genus. The key can be used to distinguish Hyalotiopsis from related genera based on morphology. Key to distinguish Hyalotiopsis from related genera 1.

However, Arx (1970) treated the same species as belonging to Lepteutypa i.e. L. indica (Punith.) Arx. Most Lepteutypa spp. have seiridium-like asexual morphs (Sutton 1980; Nag Raj and Kendrick 1985; Nag Raj 1993), thus Nag Raj and Kendrick (1985) introduced Ellurema Nag Raj & W.B. Kendr. to place Lepteutypa indica. The link between Lepteutypa indica and Hyalotiopsis subramanianii was confirmed by Nag Raj (1993), thus we propose to adopt older asexual typified name, Hyalotiopsis over younger sexual typified name Ellurema.

Sacc., Michelia 2(no. 7): 367 (1881) ≡ Myrothecium trochiloides Sacc., Michelia 1(no. 4): 367 (1878) Notes: Saccardo (1881) introduced Hymenopsis with H. trochiloides as the type species. Currently, 35 species epithets are listed in Index Fungorum (2016), but Sutton (1980) and Nag Raj (1993) each accepted only four species. Including the type, Sutton (1980) accepted H. saccardoana (Speg.) B. Sutton, H. typhae (Höhn.) B. Sutton, and H. argentinensis (Speg.) B. Sutton, while Nag Raj (1993) accepted H. atroviridis (Berk. & Broome) Nag Raj, H. caricis (Fuckel) Nag Raj and H. typhae (Höhn.) B. Sutton. Nag Raj (1993) also listed 27 taxa under ‘unexamined and excluded taxa’ while Myrothecium flavovirens B. Sutton was treated as Hymenopsis flavovirens (B. Sutton) Nag Raj. Since Nag Raj (1993) only three species have been introduced i.e. H. bambusae Nag Raj, H. olivacea Nag Raj (Nag Raj 1995), and H. chlorothrix Kohlm. & Volkm.-Kohlm (Kohlmeyer and Volkmann - Kohlmeyer 2001).

Kaleidosporium is morphologically distinct from other genera with muriform conidia such as Camarosporium and Stegonsporium. Both the latter genera have transverse and vertical septa (Sutton 1980), while conidia of Kaleidosporium have only oblique septa from its earlier stages of development (van Warmelo and Sutton 1981).

Type species: Kalmusia ebuli Niessl, Verh. nat. Ver. Brünn 10: 204 (1872) Notes: The genus Dendrothyrium was introduced by Verkley et al. (2014) with D. variisporum Verkley et al. The genus is characterised by aseptate, olivaceous brown, thin and smooth-walled conidia and phylogenetically clusters in Didymosphaeriaceae (Ariyawansa et al. 2014b; Verkley et al. 2014). However, Ariyawansa et al. (2014b) showed that the type species of Dendrothyrium, D. variisporum and D. longisporum Verkley et al. grouped in Kalmusia sensu stricto, thus the former name was reduced to synonymy under the latter generic name.

Sutton, The Coelomycetes (Kew): 78 (1980); Fig. 124 Fungal Diversity See Index Fungorum for synonyms Notes: Anahosur (1969) introduced Kamatella with K. indica as the type species. Index Fungorum (2016) lists four species epithets, including the type species. However, Sutton (1980) found that Ascochyta apiospora as the oldest name of Kamatella indica thus former species was transferred to Kamatella. Further, Sutton (1980) listed all other species under Kamatella apiospora as its synonyms thus, the genus remains monotypic. The genus was not re-visited since Sutton (1980). Sequence data is unavailable, hence the taxonomic placement is uncertain. Laeviomyces D. Hawksw., Bull. Br. Mus. nat. Hist.

Several former Laeviomyces species have been transferred to Lichenodiplis by Diederich; apart from the aseptate conidia, they can hardly be distinguished from Lichenodiplis, and are better accommodated in that genus.

However, Griffon and Maublanc (1909) transferred Botryodiplodia theobromae to Lasiodiplodia. As pointed out by Sutton (1977, 1980) the epithet theobromae (1892) is older than tubericola (1896), Table 5 Plant pathogenic Lasiodiplodia species Species Host plant Reference L. crassispora Grapevine Van Niekerk and Bester 2010 L. egyptiacae Mango Ismail et al. 2012 Cashew Olunloyo 1979; Adeniyi et al. 2013 L. plurivora Prunus spp. Damm et al. 2007a, b L. pseudotheobromae Mango L. theobromae Ismail et al. 2012 Mango Ismail et al. 2012 Banana Thangavelu et al. 2007 Fungal Diversity Fig. 128 Lasmenia balansae (Material examined: Paraguay, Paraguari, Cerro Hu, IMI 200651). a, b Herbarium label and material. c, d Vertical sections of conidiomata. e, f Conidia.

Currently 37 species epithets are listed in Index Fungorum (2016). Although Denman et al. (2000) suggested that Lasiodiplodia could be a synonym of Diplodia, Pavlic et al. (2008), Phillips et al. (2008, 2013), Liu et al. (2012) and Slippers et al. (2013) recognized Lasiodiplodia as a distinct genus in Botryosphaeriaceae. Slippers et al. (2013) showed that Macrovalsaria Petr. grouped with Lasiodiplodia sensu lato. Subsequent sequence based studies recognized that L. theobromae is a complex of cryptic species (Pavlic et al. 2004, 2008; Burgess et al. 2006; Damm et al. 2007a, b; Alves et al. 2008; Abdollahzadeh et al. 2010; Ismail et al. 2012).

Fungal Diversity Lectotype species: Lasmenia balansae Speg., Anal. Soc. cient. argent. 22(2): 152 (1886); Figs. 128 and 129 Notes: Spegazzini (1886) introduced Lasmenia with L. balansae as the type species. Von Höhnel (1910) designated the lectotype for the type species. There are 12 species epithets listed in Index Fungorum (2016), however, Petrak and Sydow (1927) transferred several species to Lasmeniella. Lasmenia and Lasmeniella share close morphological characters and are difficult to distinguish. However, Sutton (1980) stated Lasmeniella has ‘cylindrical to tapered above’ conidiogenous cells, while Lasmenia has cylindrical conidiogenous cells. Nevertheless, Sutton (1980) stated that Lasmenia needs extensive re-assessment (See further comparisons under notes in Lasmeniella). Nishijima et al. (2002), Serrato-Diaz et al. (2011) reported Lasmenia spp. as pathogen on rambutan in Hawaii and Puerto Rico, respectively. Further, SerratoDiaz et al.

Subsequently, Petrak (1929) and Sydow (1934) added three more species and currently 13 records have been accepted (Sutton 1980; Index Fungorum 2016). Nag Raj and DiCosmo (1981b) and Nag Raj (1993) re-described the genus and provided illustration of type species.

Scale bars: e, f = 100 μm, g–j = 20 μm, k–s = 10 μm In morphology of conidia, Lasmeniella closely resembles Lasmenia, which has brown conidia with a truncate base (Sutton 1980). However, Nag Raj and DiCosmo (1981b) and Nag Raj (1993) stated Lasmeniella has a tubular, subcylindrical basal appendage, but Sutton (1980) did not mention the basal appendage. Nag Raj (1993) illustrated and re-described L. congoensis (Har. & Pat.) Petr. & Syd. in addition to the type species. However, Sutton (1980) used conidiomatal characters to distinguish Lasmenia and Lasmeniella, i.e. unilocular and multilocular stromata in Lasmenia and Lasmeniella, respectively. Nevertheless, Nag Raj and DiCosmo (1981b) stated, Lasmenia also has ‘irregular multilocular stromata’ thus distinguishing the genera based on stromatic characters is uncertain. Thus, we conclude presence of basal appendage of conidia is the most reliable character to distinguish Lasmenia and Lasmeniella. Currently sequence data is unavailable, thus the taxonomic placement is uncertain. Lecanosticta Syd., Annls mycol. 20(3/4): 211 (1922) = Eruptio M.E.

Conidia fusiform or subcylindrical, tapered to the rounded apex and truncate base, straight to curved, septate, continuous, pale brown to brown, guttulate, verruculose, base with minute marginal frill (Nag Raj 1977; Sutton 1980; Marmolejo 2000; Quaedvlieg et al. 2012). Type species: Lecanosticta acicola (Thüm.) Syd., Annls mycol. 22(3/6): 400 (1924); Fig. 132 See Quaedvlieg et al. (2012) for synonyms Notes: Sydow and Petrak (1922) introduced Lecanosticta with Lecanosticta pini, but Petrak and Sydow (1924) found that Lecanosticta acicola (Thüm.) Syd. (≡ Cryptosporium acicola Thüm.) is the oldest name for Lecanosticta pini. Hence, the former species epithet was treated as the type species, while the latter epithet has been listed as its synonym.

(2012) showed Lecanosticta acicola clusters in Mycosphaerellaceae and our phylogenetic analyses also agree with this (Fig. 11). Crous et al. (2009b) also treated Mycosphaerella dearnessii M.E. Barr (Barr 1972) as the sexual morph of Lecanosticta acicola. However, Barr (1996) erected Eruptio M.E. Barr for Mycosphaerella dearnessii and named as Eruptio acicola (Dearn.) M.E. Barr (≡ Oligostroma acicola Dearn.). Quaedvlieg et al. (2012) listed both Oligostroma acicola and Mycosphaerella dearnessii under the oldest name Lecanosticta acicola. Wijayawardene et al.

Paulo 40(2): 153 (1973) Notes: Sutton and Crous (1997) introduced Lecanostictopsis with L. kamatii as the type species. Sutton and Crous (1997) introduced L. noumeaensis B. Sutton & Crous and L. syzygii (Ciccar.) B. Sutton & Crous (≡ Scolicosporium syzygii Ciccar.), as well as the type species. Crous (1998) introduced a fourth species, L. eucalypti Crous. Lecanostictopsis shows close conidial morphology with Pseudocercospora and Cercospora which are hyphomycetous (Sutton and Crous 1997; Seifert et al. 2011). Sutton and Crous (1997) compared Lecanostictopsis with Lecanosticta. However, Lecanostictopsis shows ‘dark to reddish brown, coarsely verruculose’ conidiogenous cells while Lecanosticta shows ‘hyaline to pale brown and verruculose conidiogenous cells (Sutton and Crous 1997). Sequence data is unavailable, thus the taxonomic placement is uncertain.

Közl. 14(5–6): 157 (1915) Notes: Sydow (1923) erected Leptomelanconium to place Melanconium asperulum and treated Leptomelanconium asperulum as the type species. However, Petrak (1962) found that Cryptomela allescheri is similar to Leptomelanconium asperulum thus, transferred it to Leptomelanconium and treated it as the type species. Sutton (1977, 1980) agreed with Petrak (1962) and listed Leptomelanconium asperulum under L. allescheri. Crous et al. (2009b) showed that Leptomelanconium australiense B. Sutton groups in Teratosphaeria sensu stricto (Fig. 11). Thus, it was transferred to Teratosphaeria as T. australiensis. However, neither the cultures nor sequences are available for Leptomelanconium allescheri, hence the taxonomic status of Leptomelanconium sensu stricto is uncertain. Lichenoconium Petr. & Syd., Beih.

Fauna Flora fenn. 14: 107 (1888) Notes: In their taxonomic studies, Keissler (1910) and Vouaux (1914) treated ‘lichenicolous fungi forming singlecelled dark brown conidia in irregularly opening pycnidia as Coniothyrium’ (Hawksworth 1977). However, Petrak and Sydow (1927) introduced Lichenoconium based on L. lichenicola as the type species. Hawksworth (1977) revised the genus and accepted 10 species.

Scale bars: a = 100 μm, b– d = 10 μm (re-drawn from Sutton 1980) Based on nuLSU and mtSSU sequence data, Lawrey et al.

Sequences of lichenicolous Microsphaeropsis species (i.e. M. caloplacae Etayo & Yazici, M. lichenicola Etayo and M. physciae Brackel) are not available thus the phylogenetic placement is uncertain. It is important to re-examine holotype specimens of these species and compare them to Acaroconium, where they might be better placed rather than maintaining them under Microsphaeropsis. Moreover, a phylogenetic assessment will be helpful to clarify the taxonomic placement of these taxa, as Microsphaeropsis sensu stricto belongs in Didymellaceae (de Gruyter et al. 2009; Wijayawardene et al. 2014d). ** Following the original descriptions, the lichenicolous Phaeoseptoria peltigerae and the genus Lichenohendersonia are morphologically very similar and can hardly be distinguished at generic level.

Type species: Macrodiplodiopsis desmazieri (Mont.) Petr., Annls mycol. 20(5/6): 343 (1922); Fig. 140 Notes: Petrak (1922) introduced Macrodiplodiopsis with M. desmazieri. It is an appendage bearing coelomycetous genus (Sutton 1980; Wijayawardene et al. 2014b). However, Nag Raj (1993) did not mention the gelatinous sheath. Shear and Davidson (1936) mentioned that M. desmazieri (Mont.) Petr. (as Hendersonia desmazieri Mont.), the type species of Macrodiplodiopsis, is the asexual state of Massaria platani Ces. (current name Splanchnonema platani (Ces.) M. E. Barr), but Glawe (1985) rejected this link. Crous et al.

(2006b, 2015a) redescribed Macrohilum eucalypti and concluded it belongs to Diaporthales based on LSU and ITS sequence data. Moreover, Crous et al. (2015a) introduced Macrohilaceae to accommodate Macrohilum as it clustered in a distinct clade in Diaporthales. Our phylogenetic analyses (Fig. 12) also agree with the findings in Crous et al. (2015a).

Type species: Macrophomina phaseolina (Tassi) Goid., Annali Sper. agr. N.S. 1: 457. 1947; Fig. 142 Notes: Petrak (1923b) introduced Macrophomina with M. philippinensis as the type species. von Arx (1981) introduced Tiarosporella phaseolina (Tassi) van der Aa for the same taxon and reduced Macrophomina under Tiarosporella. The genus Tiarosporella [type species: T. paludosa (Sacc. & Fiori ex P. Syd.) Höhn.] has smooth, hyaline conidiogenous cells, which lack periclinal thickenings and percurrent proliferations and has hyaline, bcylindrical to fusiform conidia that have irregular apical mucoid appendages (Crous et al. 2006a, b). Hence, Crous et al. (2006a) resurrected the genus Macrophomina and treated Macrophomina phaseolina as the type species. Phillips et al. (2013) also accepted this. Immature stage of Macrophomina also shows similar conidial characters to Tiarosporella but become medium to dark brown at maturity (Crous et al. 2006a; Phillips et al. 2013). Moreover, phylogenetic analyses show Tiarosporella has distinct phylogenetic lineage from Macrophomina in Botryosphaeriaceae (Phillips et al. 2013; Crous et al. 2015a; Fig. 10). Premamalini et al. (2012) reported Macrophomina phaseolina as a human pathogen. Magnicamarosporium Kaz. Tanaka & K.

(2015) introduced Magnicamarosporium with M. iriomotense as the type species. Magnicamarosporium resembles Amarenographium, Camarosporellum and Camarographium. However, Amarenographium has gelatinous cap-like appendage and both Camarosporellum and Camarographium lack paraphyses. In phylogenetic analyses, Tanaka et al. (2015) showed M a g n i c a m a ro s p o r i u m i r i o m o t e n s e g r o u p e d i n Sulcatisporaceae, Massarineae and this placement is confirmed by our phylogenetic analyses (Fig. 15).

Type species: Massariothea themedae Syd., Annls mycol. 37(3): 249 (1939); Fig. 144 Notes: Sydow (1939) introduced Massariothea with M. themedae as the type species. Sutton (1980) accepted four species viz. M. botulispora (Teng) B. Sutton, M. paspal (Ellis & Everh.) B. Sutton, M.shawiae (B. Sutton) B. Sutton and M. themedae. Subsequently, M. attenuata B. Sutton & Alcorn (Sutton and Alcorn 1985), M. scotica B. Sutton & Rizwi (Sutton and Rizwi 1980), M. similis Alcorn and M. triseptata Alcorn (Alcorn 1993) have been added to the genus, thus eight species are presently accepted.

Type species: Melanconiopsis inquinans Ellis & Everh., Bull. Torrey bot. Club 27: 575 (1900) Notes: Ellis and Everhart (1900) introduced Melanconiopsis with M. inquinans as the type species. Sutton (1980) included taxonomic notes and illustrations of the type species. Currently there are eight epithets listed in Index Fungorum (2016) however, most have been transferred to other genera (Table 6). Thus, beside the type species, only M. microspora V.L. Suárez et al. would be treated as Melanconiopsis sensu stricto (Suarez et al. 2000). Sequence data is unavailable in GenBank thus taxonomic placement is uncertain. Melanconium Link, Mag.

Type species: Melanconium atrum Link, Mag. Gesell. naturf. Freunde, Berlin 3(1–2): 9 (1809) Notes: Link (1809) introduced the genus Melanconium with M. atrum as the type species. Currently, over 200 epithets are listed in Index Fungorum (2016). Sutton (1964) revised the genus and Sutton (1980) provided taxonomic notes. Sieber et al. (1991) compared Melanconium apiocarpum, M. marginale and other Melanconium spp. from Alnus spp. based on morphological, cultural and biochemical methods. Further, Sieber et al. (1991) reported that M. apiocarpum can cause diseases on Alnus sp. Belisario (1999) also reported that M. juglandinum, is a pathogen that cause black pustular dieback of Juglans spp. in Europe. Traditionally, Melanconium was listed as the asexual morph of Melanconis Tul. & C. Tul. (Tulasne and Tulasne 1863; Wehmeyer 1941; Sieber et al. 1991). Sieber et al. (1991) regarded Melanconium apiocarpum and M. marginale as the asexual morph of Melanconis alni and M. marginalis, respectively. Species Re-deposition Reference M. africana Luc M. ailanthi Höhn.

Voglmayr and Jaklitsch (2012) also reported several Melanconiella spp. with discosporina-like asexual morphs. Voglmayr and Jaklitsch (2012) questioned the reliability of existing species epithets of Melanconium as many binomials are based on host association. Further, original materials are not in good condition for examination or unavailable, thus it is essential to carry out generic Fungal Diversity revision based on morpho-molecular analyses (Voglmayr and Jaklitsch 2012). There are several sequences present in GenBank under the name of Melanconium. However, sequences of the type species are unavailable thus, and therefore the taxonomic position is uncertain. Melanconium carpinicola Wijayaw., Camporesi, McKenzie & K.D. Hyde, sp. nov. Index Fungorum number: IF551782; Facesoffungi number: FoF 01526; Fig. 146 Etymology: Named after the host genus Holotype: MFLU 15–1098 Saprobic on stem and branches of Carpinus betulus. Sexual mor ph: Unde termined. Asexual morph: Conidiomata 350–700 μm diam., 200–450 μm high, acervular, superficial, solitary, convoluted, dark brown, conidia mass oozing out of the conidiomata, globose to subglobose, unilocular. Conidiomata wall outer layer thin, composed of hyaline to pale brown walled cells of textura angularis, inner layer thin, hyaline. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 10–40 × 3– 4 μm, long, annellidic, hyaline to pale brown, integrated, determinate, cylindrical, smooth-walled. Conidia 12–17 × 9– 12 μm, (x = 14.6 × 10.1 μm, n = 20), globose to ellipsoid, truncate at the base, aseptate, brown to dark brown, guttulate, thick-walled, verrucose. Material examined: Italy, Forlì-Cesena [FC] Province, Forlì - Via Risorgimento, on dead branches of Carpinus betulus L. (Betulaceae), 23 April 2014, Nello Camporesi, IT 1622 (MFLU 15–1098, holotype). Notes: Our collection is morphologically similar to the asexual morph of Melanconiella decorahensis. However, Melanconium deplanatum (current name in Species Fungorum Myxofusicoccum deplanatum (Speg. & Roum.) Died.), M. ramulorum (9–10 × 7–8 μm), M. stromaticum (22–25 × 20 μm fide Corda 1833) and M. triangulare Ellis & Everh. (only length was given 5–6 μm fide Ellis and Everhart 1886) are also recorded from Carpinus spp. (Farr and Rossman 2015). Our collection of melanconium-like taxon is distinct from the conidial morphology of other species recorded on Carpinus spp. thus we introduce a new species. Several attempts to culture the fungus were unsuccessful and hence identification is based on morphology and host association. Melanocamarosporium Wijayaw., Camporesi, D.J. Bhat & K.D.

Notes: In morphology, our collection from Galium sp. resembles Camarosporium sensu stricto. However, in phylogenetic analyses, it clusters in Melanommataceae (Fig. 9). Currently, there are no camarosporium-like taxa reported in Melanommataceae (Wijayawardene et al. 2014c; Tian et al. 2015), and therefore we introduce Melanocamarosporium to accommodate our new collection.

Sutton (1977, 1980) and Kirk et al. (2013) accepted Melanophoma. Papendorf (1967a) stated the conidial wall to be smooth, but Sutton (1980) found it to be verruculose. The genus remains monotypic and sequence data is unavailable, thus the taxonomic placement is uncertain. In conidial morphology, Melanconiopsis, Melanconium and Melanophoma share very similar characters such as ovoid or globose to ellipsoid, dark to dark brown, guttulate, thickwalled conidia.

Hyde Notes: The genus Melnikia is introduced to accommodate our collection from Anthoxanthum sp., characterised by pycnidial conidiomata, phialidic conidiogenesis and phragmosporous, pale brown to brown conidia. The conidial morphology of Melnikia resembles Pseudohendersonia. However, Pseudohendersonia has eguttulate and brown to dark brown conidia (Crous and Palm 1999b; Fig. 9), while Melnikia has guttulate, pale brown to brown conidia. In phylogenetic analyses, the type species of Melnikia resides in Phaeosphaeriaceae. The type species of Pseudohendersonia lacks sequence data, however, in this study we introduce P. galiorum which resides in Didymellaceae (Fig. 9).

Conidia pyriform or short cylindrical or fusiform or globose to subglobose, pale brown to brown, aseptate, some species are guttulate, thin to thick and smooth-walled (Sutton 1980; Matsushima 1996, 2001; van der Aa and Vanev 2002; Etayo and Yazici 2009; Alves et al. 2010; Crous et al. 2011c). Type species: Microsphaeropsis olivacea (Bonord.) Höhn. [as ‘olivaceus’], Hedwigia 59: 267 (1917) Notes: Von Höhnel (1917) introduced the genus Microsphaeropsis with M. olivaceus (current name M. olivacea) as the type species. Currently, there are about 5 0 e p i t h et s l i s t e d i n I n de x F un g o r u m ( 2 0 16 ) . Coniothyrium-like taxa and Microsphaeropsis share similar morphological characters such as shape and pigmentation of the conidia, thus taxonomists faced difficulties determining generic boundaries (Sutton 1977, 1980). Hence, Sutton (1980) categorized species with thinwalled, 1-celled conidia and phialidic conidiogenesis as Microsphaeropsis. This concept was accepted and expanded by de Gruyter et al. (2013) who stated ‘Microsphaeropsis is characterised by the production of phialidic conidiogenous cells with periclinal thickening, and thin-walled, pale greenish brown conidia.’ However, recent phylogenetic studies reveal coniothyrium-like taxa and microsphaeropsis-like taxa are polyphyletic in Capnodiales and Pleosporales (Verkley et al. 2004, 2014; Cortinas et al. 2006; de Gruyter et al. 2009, 2013). Most of these taxa reside in Pleosporales viz. Microsphaeropsis sensu stricto in Didymellaceae (Verkley et al. 2004; de Gruyter et al. 2009; Wijayawardene et al. 2014d), Paraconiothyrium sensu stricto in Didymosphaeriaceae (Verkley et al. 2004, 2014; Damm et al. 2008; Ariyawansa et al. Fig. 150 Microsphaeropsis sp. (Material examined: Italy, Arezzo [AR] Province, near Croce di Pratomagno, on dead branch of Cytisus scoparius, 24 June 2012, E.

Thus, it is highly recommended to rely on molecular data to confirm the correct generic placement of such genera with higher plasticity in morphology. A taxonomic key to distinguish Microsphaeropsis and coniothyrium-like taxa is provided under Coniothyrium. Brackel (2014), Etayo and Sancho (2008), and Etayo and Yazici (2009) introduced Microsphaeropsis caloplacae Etayo & Yazici, M. lichenicola Etayo and M. physciae Brackel as lichenicolous species. However, sequence data of both species are unavailable thus taxonomic placements are unavailable. Minutoexcipula V. Atienza & D. Hawksw., Mycol.

Asexual morph: Conidiomata in the type species sporodochia, superficial, single, dark brown to black, in some species pycnidial when young. Conidiophores macronematous, short-cylindrical, septate, branched, smooth, hyaline to pale brown. Conidiogenous cells enteroblastic, annellate, terminal percurrently proliferating, cylindrical, integrated, subhyaline, smooth. Conidia ellipsoid, rounded at the apex and truncated at the base, (0−)l-septate, pale to dark brown, smooth-walled (Atienza and Hawksworth 1994; Atienza et al. 2009). Type species: Minutoexcipula tuckerae V. Atienza & D. Hawksw., Mycol. Res. 98(5): 587 (1994) Notes: Atienza et al. (1994) introduced Minutoexcipula with M. tuckerae as the type species and compared the new genus to similar genera with sporodochia-like conidiomata. Seifert et al. (2011) listed Minutoexcipula as a hyphomycetous genus. Some species, such as M. mariana V. Atienza, have pycnidial conidiomata when young. Monochaetia (Sacc.) Allesch., Rabenh.

Sexual morph: Undetermined. Asexual morph: Conidiomata acervular, superficial to subepidermal, solitary or gregarious, occasionally confluent, unilocular, globose. Conidiomata wall multi-layered, composed of thin-walled, brown cells of textura angularis. Conidiophores cylindrical, straight or occasionally curved, hyaline, sparsely branched and septate only at the base. Conidiogenous cells holoblastic, annellidic, indeterminate, discrete, hyaline, cylindrical, smooth. Conidia fusiform, straight to slightly curved, 3–5-septate, continuous or constricted at the septa, apical and basal cell hyaline, median cells thick-walled, brown, smooth-walled; with an unbranched, short, central basal appendage; with simple or branched, filiform apical appendage (Sutton 1980; Nag Raj 1993; Matsushima 1996; Maharachchikumbura et al. 2015; Senanayake et al. 2015). Type species: Monochaetia monochaeta (Desm.) Allesch., Rabenh. Krypt.-Fl., Edn 2 (Leipzig) 1(7): 667 (1902) [1903]; Fig. 152 Notes: Allescher (1902) introduced the genus Monochaetia with M. monochaeta as the type species. Guba (1961) revised the genus and accepted 41 species with 3–5-septate conidia. However, Nag Raj (1993) mentioned that most of these species belong to Seimatosporium or Seiridium and thus accepted only 12 species, while listing 98 species under ‘unexamined and excluded genera’. Currently, there are 121 species epithets listed under Monochaetia in Index Fungorum (2016), but most have been transferred to other genera such as Seiridium, Seimatosporium, Sarcostroma (Species Fungorum 2016). Based on phylogenetic analyses, Jeewon et al. (2002) showed that Monochaetia clustered in Amphisphaeriaceae with several other appendaged bearing genera such as Discosia and Pestalotiopsis. However, Jeewon et al. (2002) stated that it is essential to resolve the generic concept of Monochaetia as it shares similar morphological characters with Seiridium and Seimatosporium. Maharachchikumbura et al. (2015) listed Monochaetia under Amphisphaeriaceae but Senanayake et al. (2015) showed it belongs to Pestalotiopsidaceae. Our phylogenetic analyses also agree with findings in Senanayake et al. (2015) (Fig. 16). Currently 38 different sequences are available in GenBank, but sequence for the type species is not available. Thus it is essential to carry out further recollections and morpho-molecular analyses to confirm correct generic boundaries of the genus. Monochaetinula Muthumary et al., Trans. Br. mycol. Soc. 87(1): 104 (1986) Facesoffungi number: FoF 01532; Fig. 154 Sordariomycetes, Xylariomycetidae, Amphisphaeriales, genera incertae sedis Endophytic or saprobic on various substrates of a range of host plants. Sexual morph: Undetermined. Asexual morph: Conidiomata stromatic or pynidial, immersed or suberumpent, solitary, unilocular or multi-locular, globose or glabrous, brown, ostiolate. Ostiole apapillate, single, circular. Conidiomata wall composed of pale brown-walled cells of textura angularis. Paraphyses filiform, septate, hyaline. Conidiophores reduced to conidiogenous cells or if present, filiform or cylindrical or irregular, septate, sparingly branched, hyaline, smooth. Conidiogenous cells holoblastic, annellidic, cylindrical to irregular, discrete or integrated, hyaline, smooth. Conidia fusiform, 3–4-septate, continuous or constricted, with olivaceous to pale brown median cells; apical cell conic, hyaline, with a short simple appendage; basal cell hyaline, with or without a simple appendage (Muthumary et al. 1986; Nag Raj 1993; Matsushima 1996). Type species: Monochaetinula terminaliae (Bat. & J.L. Bezerra) Muthumary et al., Trans. Br. mycol. Soc. 87(1): 106 (1986); Fig. 154 ≡ Monochaetia terminaliae Bat. & J.L. Bezerra, Publicações Inst. Micol. Recife 298: 13 (1960) Notes: Muthumary et al. (1986) erected Monochaetinula to place Monochaetia terminaliae and named it as Monochaetinula terminaliae. The original generic description of Monochaetinula (Muthumary et al. 1986) and Nag Raj (1993) did not mention the presence of paraphyses. However, Matsushima (1996) Fungal Diversity Fig. 152 Monochaetia monochaeta (Material examined: Germany, on leaf of Quercus robur, 21 December 2013, René K.

Monochaetinula closely resembles Monochaetia but the former has stromatic or pycnidial conidiomata, while the latter has acervular conidiomata. However, it is important to carry out molecular analyses of both taxa to delimit clear generic boundaries. Currently six species epithets are listed in Index Fungorum (2016). Sequence data is unavailable, thus taxonomic placement is uncertain. Morinia Berl. & Bres., Annuario Soc. Alpinisti Trident., 1887–88: 82 (1889) [1887–88] Facesoffungi number: FoF 01533; Fig. 155 Sordariomycetes, Xylariomycetidae, Amphisphaeriales, Bartaliniaceae Endophytic or saprobic on stems of Ericaceae (Dicotyledons). Sexual morph: Undetermined. Asexual morph: Conidiomata acervular, subepidermal to partially immersed, separate, globose to subglobose, circular, dark brown to black. Conidiomatal wall composed of thin-walled, pale brown, cells of textura angularis. Conidiophores cylindrical, flexuous, septate, simple or branched at the base, hyaline, smooth-walled. Conidiogenous cells holoblastic, integrated, indeterminate, cylindrical, hyaline, smooth. Conidia fusiform to ellipsoid, straight to slightly curved, muriform, with 5–6 transverse septa, and 1–3 vertical septa or septa oblique, apical and end cells hyaline to sub-hyaline, median cells medium brown, smoothwalled, basal cell truncate with the remains of the conidiogenous cell attached; apical cell conic with 2–4 cellular, unbranched, filiform appendage (Sutton 1980; Collado et al. 2006). Type species: Morinia pestalozzioides Berl. & Bres., Annuario Soc. Alpinisti Trident., 1887–88: 82 (1889) [1887–88]; Fig. 155 Notes: Berlese and Bresadola (1889) introduced Morinia with M. pestalozzioides as the type species. Sutton (1977, 1980) accepted Morinia as a monotypic genus and Collado et al. (2006) introduced a second species, M. longiappendiculata Collado & Platas. Further, Collado et al. (2006) showed M. longiappendiculata has close relationship with Truncatella and Bartalinia in Amphisphaeriaceae in their molecular data analyses. In phylogenetic analyses, Morinia sensu stricto groups as a monotypic clade in Bartaliniaceae (Fig. 16). In morphology, Morinia has unique conidial characters as other members in Bartaliniaceae lack vertical or oblique septa.

Conidiogenous cells percurrently proliferating, with flared collarette, lageniform to subcylindrical, smooth, hyaline, invested in mucus. Conidia oval to ellipsoidal, aseptate, brown, thick-walled, smooth to finely verruculose, lacking striations, appendaged; apical appendage extracellular, mucilaginous, irregular, smooth, hyaline; basal appendage tubular, thin-walled, hyaline and smooth (description modified from Crous et al. 2015b). Type species: Mucoharknessia cortaderiae Crous et al., Phytotaxa 202 (2): 86 (2015); Fig. 156 Notes: Crous et al. (2015b) introduced Mucoharknessia with M. cortaderiae as the type species. In morphology, Mucoharknessia resembles Harknessia, but the latter genus lacks mucilaginous apical appendages in the conidia (Crous et al. 2015b). In phylogeny, Mucoharknessia clusters in Botryosphaeriaceae (Crous et al. 2015b; Fig. 10) while Harknessia resides in Harknessiaceae, Diaporthales (Crous et al. 2012d; Fig. 12).

Hist., Ser. 2 5: no. 415 (1850) = Myxocyclus confluens Riess, Beitr. Mykol. 2: 63 (1852) Notes: Fresenius (1852) introduced Myxocyclus with M. confluens as the type species. However, Sutton (1975a, 1977, 1980) treated Hendersonia polycystis as the oldest name of the taxon and thus transferred to Myxocyclus as M. polycystis At the same time, M. polycystis was treated as the type species, while M. confluens treated as its synonym. Petrak (1927) introduced M. cenangioides (Ellis & Rothr.) Petr., but Sutton (1980) stated that it is not congeneric with the type species, thus its placement is uncertain. Saccardo (1908) and Barr (1982) predicted Splanchnonema argus (Berk. & Broome) Kuntze, as the sexual morph of Myxocyclus polycystis based on the cooccurrence of both morphs on same host. This link was proved in culture methods by Tanaka et al. (2005). However, Splanchnonema argus is not the type species of Splanchnonema. Further, Splanchnonema argus lacks sequence data to confirm whether it belongs to Splanchnonema sensu stricto. Hence, we do not reduce Myxocyclus under Splanchnonema until S. argus is shown to be congeneric with Splanchnonema sensu stricto. Sequence data of Myxocyclus polycystis is unavailable, thus taxonomic placement is unclear. Nagrajomyces Mel’nik, Mikol.

The genus remains monotypic and sequence data is unavailable. Hence, the taxonomic placement is uncertain. In conidial morphology, Nagrajomyces resembles Uniseta as the latter taxon also has a single, unbranched apical appendage. However, Uniseta has conidia with a single septum while, Nagrajomyces has muriform conidia (Nag Raj 1974). Neocamarosporium Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol.

(2015) introduced Neocurreya to accommodate Curreya austroafricana which is not congeneric with Curreya sensu stricto in Cucurbitariaceae (Doilom et al. 2013). At the same time, Thambugala et al. (2015) introduced three new combinations; N. claviformis (Mugambi & Huhndorf) Thambug. & K.D. Hyde, N. grandicipis (Joanne E. Taylor & Crous) Thambugala & K.D. Hyde and N. proteae (Marinc. et al.) Thambugala & K.D. Hyde. Our phylogenetic analyses also agree with findings in Thambugala et al. (2015) (Fig. 14) and confirm the placement of Neocurreya in Floricolaceae, Pleosporales. Crous et al. (2015c) introduced Curreya acaciae Crous & M.J. Wingf. based on mega blast results but our phylogenetic showed it belongs to Neocurreya, thus we provide a new combination.

Type species: Neodeightonia subglobosa C. Booth, Mycol. Pap. 119: 19 (1970) [1969]; Fig. 164 Notes: Punithalingam (1969) introduced Neodeightonia with N. subglobosa as the type species. von Arx and Müller (1975) treated Botryosphaeria with a broad generic concept and reduced Neodeightonia to synonymy under Botryosphaeria. Crous et al. (2006a) did not recognize Neodeightonia as a genus in Botryosphaeriaceae. However, Crous et al. (2006a) showed Botryosphaeria subglobosa (C. Booth) Arx & E. Müll. (CBS 448.91) grouped away from Botryosphaeria sensu stricto and compared the conidial morphology with Diplodia and Lasiodiplodia. Phillips et al. (2008) also recognized Botryosphaeria subglobosa (CBS 448.91) as a distinct species and hence reinstated Neodeightonia to accommodate it. Phillips et al. (2008) also introduced N. phoenicum A.J.L. Phillips et al. and Liu et al. (2010) introduced a third species, N. palmicola J.K. Liu et al.

Scale bars: a = 150 μm, b, c = 10 μm (re-drawn from Crous et al. 2011c) In conidial morphology, Neodeightonia resembles Lasiodiplodia as both have striate conidia. However, Neodeightonia can be distinguished as it lacks paraphyses while Lasiodiplodia has conspicuous paraphyses (Phillips et al. 2008, 2013). Phylogenetically, both genera are distinct in Botryosphaeriaceae (Phillips et al. 2008, 2013; Liu et al. 2010, 2012; Figs. 9 and 10). Neofusicoccum Crous et al., Stud.

Type species: Neofusicoccum parvum (Pennycook & Samuels) Crous et al., Stud. Mycol. 55: 248 (2006) Notes: Crous et al. (2006a) showed that Dichomera eucalypti (G. Winter) B. Sutton and D. versiformis Z.Q. Yuan grouped in Neofusicoccum sensu stricto. This placement was confirmed by Phillips et al. (2013) and Slippers et al. (2013). Thus, Slippers et al. (2013) concluded that dichomera-like taxa are polyphyletic and the taxa which grouped with Neofusicoccum sensu stricto were considered as synonyms of Neofusicoccum. Our multi-gene analyses of Botryosphaeriaceae (SSU, LSU, ITS, EF and βtubulin) (Fig. 10) and dichomera-like taxa (ITS and EF) (Fig. 13) also concur with the findings in both Phillips et al.

The second species, N. macrosporum H. Yonez. & Kaz. Tanaka was introduced by Yonezawa and Tanaka (2008). In morphology, Neoheteroceras is distinct from other dematiaceous coelomycetous genera with lateral appendages viz. Chithramia and Coma. Both Chithramia and Coma have 1-euseptate conidia, while Neoheteroceras has 6–15-distoseptate conidia. Sequence data is unavailable, thus the taxonomic placement of Neoheteroceras is uncertain.

Type species: Neopestalotiopsis protearum (Crous & L. Swart) Maharachch. et al., Stud. Mycol. 79: 147 (2014) Notes: Maharachchikumbura et al. (2014) resolved genera in the Amphisphaeriaceae based on analysis of LSU sequence data. The phylogeny resolved Pestalotiopsis as a distinct clade in Amphisphaeriaceae, with three well-supported groups that correlated with morphology; besides Pestalotiopsis, two new genera, Neopestalotiopsis and Pseudopestalotiopsis were proposed. Neopestalotiopsis protearum which was isolated from living leaves of Leucospermum cuneiforme in Zimbabwe was assigned as the type species of Neopestalotiopsis. Senanayake et al. (2015) showed Neopestalotiopsis and Pestalotiopsis, Pseudopestalotiopsis and Seiridium grouped as a distinct clade in Xylariales, thus introduced Pestalotiopsidaceae. Our phylogenetic analyses also agree with findings in Senanayake et al. (2015), hence we confirm the placement of Neopestalotiopsis in Pestalotiopsidaceae (Fig. 16).

Type species: Neosulcatispora agaves Crous & M.J. Wingf., Fungal Planet description sheets 371–399; Persoonia 35: 283 (2015); Fig. 174 Notes: The genus Neosulcatispora was introduced by Crous et al. (2015e) with N. agaves as the type species. Neosulcatispora resembles Chaetodiplodia, Placodiplodia and Pseudodiplodia, but only Neosulcatispora has conidia with striations (Crous et al. 2015e). In phylogenetic analyses, Crous et al. (2015e) showed that Neosulcatispora agaves clustered in Phaeosphaeriaceae. Neottiosporina Subram., Proc. Natl. Inst. Sci. India, B, Biol.

Aires, Ser. 3 13: 374 (1911) Notes: Sutton (1980) mentioned that this genus has hyaline conidia, but Nag Raj (1993) stated that conidia are ‘colourless to almost colourless or brown’. Sutton (1980) accepted eight species. Sequence data is unavailable, thus taxonomic placement is uncertain. Nigropuncta D. Hawksw., Bull. Br. Mus. nat.

Asexual morph: Conidiomata pycnidial, single, immersed, subglobose at immaturity, becoming cupuliform at maturity, hyaline, but appearing as black when covered by conidia. Conidiomata wall composed of loosely interwoven hyaline hyphae forming a textura intricata. Conidiophores unbranched or sparsely branched, hyaline, septate, composed of isodiametric cells. Conidiogenous cells holothallic, subglobose to subcylindrical, acrogenous, integrated, terminal, determinate, hyaline but becoming olivaceous at the apex. Conidia catenate at first, accumulating in a cirrhus, irregular, aseptate, dark olivaceous or black, individual cells mainly simple, rough-walled (Hawksworth 1981a, b; Alstrup 1993). Type species: Nigropuncta rugulosa D. Hawksw., Bull. Br. Mus. nat. Hist., Bot. 9(1): 46 (1981); Fig. 176 Notes: Hawksworth (1981a, b) introduced Nigropuncta with N. rugulosa as the type species. In morphology, Nigropuncta resembles Sclerococcum but that genus has superficial sporodochia (thus treated as hyphomycetous genus fide Seifert et al. 2011) and conidia smooth-walled (Hawksworth 1979). Hawksworth (1981b) compared N. rugulosa with Nigromacula uniseptata but that species has much longer and pigmented conidiogenous cells, and the conidia are consistently 1-septate and not aggregating into multicellular clumps. Moreover, Nigromacula uniseptata has conidia with a different mode of ornamentation and are produced in a dark brown pycnidium, while conidiomata of Nigropuncta rugulosa are hyaline. A taxonomic key is provided under Lichenoconium to distinguish Nigropuncta from other dematiaceous lichenicolous coelomycetous genera.

Type species: Nummospora hexamera E. Müll. & Shoemaker, Nova Hedwigia 7: 2 (1964); Fig. 177 Notes: Müller and Shoemaker (1964) introduced Nummospora with N. hexamera as the type species. The genus is monotypic and sequence data is unavailable. Hence, the taxonomic placement is uncertain. Nummospora has unique conidial morphology as it has vertically flattened conidia, but which are sphaerical in side view. Morgan-Jones (1974) used the words ‘coinshaped’ to describe above view of conidia. Most of the genera with globose conidia (in vertical or in side view) lack septa, but Nummospora has both transverse and longitudinal septa. Obstipipilus B. Sutton, Can. J.

(1972b) stated the conidiogenesis as ‘blastic-phialidic’, while Sutton (1980) and Nag Raj (1993) mentioned it as ‘annellidic’. The genus remains monotypic and sequence data is unavailable. Hence, taxonomic placement is uncertain.

Sexual morph: Undetermined. Asexual morph: Conidiomata stromatic, immersed, later erumpent, epidermal to subepidermal, solitary to gregarious, dark brown. Conidiomata wall thin, composed of brown cells of textura angularis. Conidiophores cylindrical to irregular, branched at the base, septate, pale brown to hyaline, smooth-walled. Conidiogenous cells holoblastic, integrated or discrete, determinate, cylindrical, pale brown to hyaline, smooth. Conidia fusiform to cylindrical, straight or curved or irregular, tapered to the truncate base, apex obtuse to bluntly acute, pale brown, 0–1-septate, continuous, smooth-walled, with guttulate lower cells (Kalchbrenner and Cooke 1880; Sutton 1980; Chevassut 1992). Type species: Oncospora bullata Kalchbr. & Cooke, Grevillea 9(no. 49): 19 (1880); Fig. 179 Notes: Kalchbrenner and Cooke (1880) introduced Oncospora with O. bullata as the type species. In conidial morphology, Oncospora shares a few similar characters with Caryophylloseptoria Verkley et al. which also has ‘cylindrical, straight, curved or flexuous conidia’ (Verkley et al. 2013). However, Caryophylloseptoria often has multi-septate and hyaline conidia and is thus distinct from Oncospora. Eight epithets are listed in Index Fungorum (2016) however, Sutton (1980) mentioned the genus needs revision. Orphanocoela Nag Raj, Can. J.

At the same time, Nag Raj (1989) introduced two other species, O. kranzii (B. Sutton) Nag Raj and O. maydis (Latterell & A.E. Rossi) Nag Raj as well as the type species. Orphanocoela is morphologically similar to Nagrajomyces which also has muriform conidia with a single, unbranched, attenuated basal appendage (Nag Raj 1993). However, Nagrajomyces has conidiophores with percurrent proliferation while Orphanocoela has reduced conidiophores and annellidic conidiogenous cells. Sequence data is unavailable thus taxonomic placement is uncertain. Palmiascoma Phookamsak & K.D.

Further, Verma and Kamal (1987) compared Paraaoria with morphologically similar genera in suborder Blastostromatineae viz. Aoria, Crandallia, Leptothyrina and Leptostroma (Sutton 1980). However, these genera have hyaline conidia (Sutton 1980) whereas those of Paraaoria are pale brown. Conidiomatal structure of Paraaoria is similar to that of Gaubaea, but latter genus lacks conidiophores and has eguttulate conidia without a basal frill (Sutton 1980). The genus is monotypic and lacks sequence data. Hence taxonomic placement is uncertain.

Type species: Paraconiothyrium estuarinum Verkley & Manuela Silva, Stud. Mycol. 50(2): 327 (2004) Notes: Verkley et al. (2004) introduced Paraconiothyrium with P. estuarinum as the type species. At the same time Verkley et al. (2004) predicted that Paraphaeosphaeria O.E. Erikss. as the sexual morph of Paraconiothyrium. However, Verkley et al. (2014) recognized Paraconiothyrium and Paraphaeosphaeria as two distinct genera in Didymosphaeriaceae. Damm et al. (2008), Budziszewska et al. (2011), de Gruyter et al. (2013) and Verkley et al. (2014) introduced new species and new combinations based on both morphological and molecular data studies. In conidial morphology, Paraconiothyrium is similar to Coniothyrium sensu stricto and Alloconiothyrium, as both genera have 0–1-septate conidia. However, Coniothyrium sensu stricto resides in Pleosporineae (Wijayawardene et al. 2014c) and Alloconiothyrium resides in Didymosphaeriaceae, but distinct from Paraconiothyrium (Ariyawansa et al. 2014b; Wijayawardene et al. 2014c). Hence, phylogenetic analysis is required to identify the generic placement of paraconiothyrium-like species as they similar to other coniothyrium-like taxa. Parahyalotiopsis Nag Raj, Can. J.

However, Hyalotiopsis does not have an ostiole, while Parahyalotiopsis has ostiolate pycnidia. However, we assume Hyalotiopsis and Parahyalotiopsis might be a single genus, but this needs to be confirmed by sequence data analyses. Paraphaeosphaeria O.E. Erikss., Ark.

However, Paraphaeosphaeria spartii has guttulate conidia and it is distinct in phylogeny from Paraphaeosphaeria (Figs. 9 and 15). Paulkirkia Wijayaw., Wanasinghe, Tangthirasunun, Camporesi & K.D.

Conidiomata wall several-layered, outer layer thick in above, thin at bottom, composed of thick-walled, brown cells of textura angularis, inner layer composed of thinwalled, hyaline cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, proliferating 1–2 times percurrently but mostly only 1 time, cylindrical to funnel-shaped, unbranched, discrete, indeterminate, hyaline to pale brown, smooth. Conidia ellipsoidal or oblong to irregular, rounded apex, truncate base, 0–1-septate, pale to dark brown, guttulate or eguttulate, thin-walled, verrucose. Type species: Paulkirkia arundinis Wijayaw., Wanasinghe, Tangthirasunun, Camporesi & K.D. Hyde Notes: In morphology, our new collection resembles Microdiplodia and Verrucoconiothyrium. However, the validity of Microdiplodia is questionable (see under Microdiplodia in ‘doubtful genera’) and the sequence data of type species of Microdiplodia is unavailable. In phylogenetic analyses, Paulkirkia clusters in Floricolaceae while Verrucoconiothyrium resides in Didymosphaeriaceae (Figs. 14 and 15 respectively).

Sexual morph: Undetermined. Asexual morph: Conidiomata pycnothyrial, superficial, solitary, with only upper wall, scutate, unilocular, often circular, or ellipsoid to irregular, dark brown. Conidiomata wall composed of radiate cells or textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, short, discrete, hyaline or brown. Conidia pyriform to fusiform, attenuated towards each end, apex conical to obtuse, base truncate, 4–6-septate, with black-band, continuous or slightly constricted at the septa, end cells smaller, medium brown, median cells larger, very dark brown, smooth-walled (Sutton and Pascoe 1989). Type species: Peltosoma freycinetiae Syd. & P. Syd. [as ‘freycinetia’], Leafl. of Philipp. Bot. 7: 3130 (1925); Fig. 190 Notes: Sydow (1925) introduced Peltosoma with P. freycinetiae as the type species. The genus was not addressed in Sutton (1977, 1980). However, Sutton and Pascoe (1989) re- described and illustrated the type species. In conidial morphology, Peltosoma resembles Endocoryneum (Sutton 1980; Farr et al. 1998), but latter genus shows only 3–4 transverse septa.

Conidiomata wall thin, composed of thin-walled, hyaline cells of textura angularis or textura intricata. Conidiophores cylindrical, septate only at the base, hyaline. Conidiogenous cells holoblastic, cylindrical, integrated or discrete, determinate, hyaline, smooth.

Type species: Perizomella inquinans Syd., Annls mycol. 25(1/2): 106 (1927) Notes: Sydow (1927) introduced Perizomella with P. inquinans as the type species. Sutton (1980) provided taxonomic notes and Perizomella remained a monotypic genus. Petrak (1924) introduced Davisiella elymina (Davis) Petr. as a hyperparasitic of Phyllachora sp., but it has fusiform, 1septate, hyaline conidia (Sutton 1980), and thus morphologically distinct from Perizomella.

Type species: Pestalotia pezizoides De Not., Mém. R. Accad. Sci. Torino, Ser. 2 2: 80 (1841); Fig. 192 Notes: Pestalotia has been revisited by several studies such as Guba (1961), Steyaert (1949) and Sutton (1969c). In his monograph, Guba (1961) accepted 220 species while adopting a wide generic concept of Pestalotia, treating Pestalotiopsis and Truncatella as synonyms of Pestalotia. However, Sutton (1969c, 1980) and Nag Raj (1993) rejected Guba’s generic concept and accepted taxa with 5 septa (or 6 cells) as Pestalotia. von Arx (1981) also treated Adea Petr., Ahmadinula Petr., Hyaloceras Durieu & Mont., Monochaetia (Sacc.) Allesch., Pseudopestalotia Elenkin & Ohl, Robillarda Castagne and Truncatella Steyaert as synonyms of Pestalotia however, Nag Raj (1993) rejected this. Steyaert (1949) and Sutton (1980) accepted the genus as monotypic and Nag Raj (1993) accepted only the type species, but listed over 600 names under ‘unexamined and excluded genera’. Jeewon et al. (2002) and Maharachchikumbura et al. (2011) discussed the generic boundaries between Pestalotia and Pestalotiopsis. Further, Jeewon et al. (2002) showed that Pestalotia clusters in Amphisphaeriaceae, Xylariales in their phylogenetic analyses. However, Maharachchikumbura et al. (2014, 2015) and Senanayake et al. (2015) did not recognize Pestalotia as a distinct genus and predicted it may be a synonym of Seiridium as both genera share close morphologies. Pestalotiopsis Steyaert, Bull. Jard. bot. État Brux. 19: 300 (1949) Facesoffungi number: FoF 01560; Fig. 193 Sordariomycetes, Xylariomycetidae, Amphisphaeriales, Pestalotiopsidaceae Endophytic, pathogenic or saprobic on various substrates of a range of host plants. Sexual morph: Undetermined. Asexual morph: Conidiomata acervular or pycnidioid or cornute, epidermal to subepidermal, solitary to gregarious, globose to subglobose, unilocular, dark brown to black. Conidiomata wall composed of thin-walled, brown cells of textura angularis. Conidiophores cylindrical or lageniform, branched, septate, hyaline, smooth-walled. Conidiogenous cells holoblastic to annellidic, indeterminate, integrated, cylindrical, hyaline, smooth. Conidia fusiform, straight or slightly curved, 4-septate; basal cell obconic with truncate base, hyaline, thin-walled, with an endogenous, cellular, simple or rarely branched appendage; apical cell conic, hyaline, with 2 or more apical, simple or branched, spathulate or espathulate appendages; median cells brown, concolorous or versicoloured, thick-walled, smooth or verruculose (Sutton 1980; Nag Raj 1993; Maharachchikumbura et al. 2011, 2012, 2013a, b, 2014). Type species: Pestalotiopsis maculans (Corda) Nag Raj, Mycotaxon 22(1): 47 (1985) ≡ Sporocadus maculans Corda, Icon. fung. (Prague) 3: 23 (1839) = Pestalotiopsis guepinii (Desm.)

Nat., Bot., sér. 2 13: 181 (1840) Notes: Steyaert (1949) introduced Pestalotiopsis with P. guepinii as the type species. Nag Raj (1985) observed that Sporocadus maculans (PR 155665) resembles the generic concept of Pestalotiopsis. Moreover, Nag Raj (1985) observed the isotype of Pestalotiopsis guepinii, and compared with Sporocadus maculans and regarded them to be identical. Hence, Pestalotiopsis maculans is the older for Pestalotiopsis guepinii (Maharachchikumbura et al. 2014).

Sutton (1980) and Nag Raj (1993) accepted this classification, but Guba (1961) regarded Pestalotiopsis and Truncatella as synonyms of Pestalotia. Maharachchikumbura et al. (2011) comprehensively discussed the history of Pestalotiopsis and Pestalotia and accepted the classification by Steyaert (1949). Recent publications by Maharachchikumbura et al. (2011, 2012, 2014) discussed the life history, pathogenicity and phylogenetic re-assessment of Pestalotiopsis. Maharachchikumbura et al. (2014) showed Pestalotiopsis spp. are polyphyletic in Amphisphaeriaceae and thus introduced Neopestalotiopsis and Pseudopestalotiopsis. Senanayake et al. (2015) showed Pestalotiopsis sensu stricto g r o u p e d w i t h C i l i o c h o re l l a , N e o p e s t a l o t i o p s i s , Pseudopestalotiopsis and Seiridium as a distinct clade in Amphisphaeriales thus introduced Pestalotiopsidaceae. Our phylogenetic analyses also agree with findings in Senanayake et al. (2015) (Fig. 16).

Von Arx and Müller (1954, 1975) treated Phaeobotryon as a synonym of Botryosphaeria, but Phillips et al. (2008) reinstated Phaeobotryon based on both m orphological and phylogenetic analyses. Moreover, Phillips et al. (2008, 2013) showed that Phaeobotryon has a distinct phylogenetic lineage in Botryosphaeriaceae. Sequence data are available only for Phaeobotryon mamane Crous & A.J.L. Phillips and P. cupressi Abdollahzadeh et al., which have been reported as holomorph and only asexual morph, respectively (Phillips et al. 2008; Abdollahzadeh et al. 2009). In morphology, Phaeobotryon resembles Diplodia but the latter has 1-septate and only rare becomes 2-septate (Phillips et al. 2013). However, both have distinct phylogenetic lineages in Botryosphaeriaceae (Fig. 10).

However, Petrak and Sydow (1927) found that Sphaeropsis ambigua was the oldest name and thus transferred it to Phaeocytostroma. Sutton (1964, 1977, 1980) treated Phaeocytostroma istrica as a synonym of P. ambiguum. As well as the type species, Sutton (1980) accepted only three other species viz. P. megalosporum B.

Sutton and P. sacchari var. calami (Panwar & Bohra) B. Sutton. Lević and Petrović (1997) observed α and β conidia in Phaeocytostroma ambiguum for the first time. Slavica et al. (2007) reported Phaeocytostroma ambiguum as the causal agent of root and stalk rot in maize. Kirk et al. (2008) stated Clypeoporthe Höhn. is the sexual morph of Phaeocytostroma. Lamprecht et al. (2011) and Verkley et al. (2014) showed Phaeocytostroma sacchari and P. ambigua grouped in Diaporthaceae, Diaporthales. Our phylogenetic analyses also agree with previous studies, as Phaeocytostroma ambigua, P. plurivorum and P. sacchari group in Diaporthaceae with high bootstrap values (Fig. 12).

Conidiogenous cells holoblastic, ampulliform, discrete, determinate, pale to dark brown, becoming paler, verrucose, thinner-walled and smoother towards the apices. Conidia cylindrical to subcylindrical, straight or slightly curved, apex obtuse or flattened, base truncate or rounded, aseptate, olive green, thickwalled, verrucose, smooth and thin-walled (Nag Raj 1974; Sutton 1980). Type species: Phaeolabrella eryngicola Speg., Anal. Mus. nac. Hist. nat. B. Aires 23: 117 (1912); Fig. 197 Notes: Spegazzini (1912) introduced Phaeolabrella with P. eryngicola as the type species. Nag Raj (1974) and Sutton (1980) re-described the type species. The genus was maintained as monotypic (Petrak and Sydow 1935; Sutton 1980). In morphology, Phaeolabrella is distinct from other known genera as it has aseptate conidia. Most of the genera with cylindrical to subcylindrical conidia have phragomospore conidia with smooth walls such as Dichomera, Neohendersonia, Oncospora, Phaeostagonospora. Sequence data is unavailable, thus the taxonomic placement is uncertain. 1. Conidia 24–28.5 × 10–13 μm ................. P. erumpens 1. Conidia 12–16 × 7.5–8.8 μm ...................

Conidiogenous cells percurrent proliferation, holoblastic, discrete, ampulliform or doliiform to subcylindrical, medium brown, verruculose. Conidia cylindrical to subcylindrical, truncate base, apex rounded, straight or curved, hyaline or medium red-brown, verruculose, not prominently guttulate or eguttulate, with or without marginal frill (Crous et al. 1997, 2015d; Crous 1998; Taylor and Crous 1999). Type species: Phaeophleospora eugeniae Rangel, Decheniana 18: 162 (1916); Fig. 198 Notes: Rangel (1916) introduced Phaeophleospora based on P. eugeniae as the type species. Sutton (1977) did not list Phaeophleospora as an accepted genus and referred it as nomina dubia as the original description was poor. Crous et al. (1997) collected new specimens, resurrected the genus, transferred several species to the genus and designated a neotype. Crous et al. (1997) treated Kirramyces as a synonym of Phaeophleospora as the latter is the oldest name. However, Andjic et al. (2007a) showed that Kirramyces (current name Teratosphaeria) is phylogenetically distinct from P. eugeniae and that Phaeophleospora is polyphyletic. Hence, Phaeophleospora was restricted only to the type species. Crous et al. (2007, Crous et al. 2009b, 2015a, b) accepted Phaeophleospora as a member of Mycosphaerellaceae however, further re-collections and culture studies are essential. Nevertheless, Crous et al. (2015d) introduced P h a e o p h l e o s p o r a p a r s o n i a e C r o u s , a n d P. hymenocallidicola Crous which has hyaline conidia. Hence, the generic boundaries of Phaeophleospora sensu stricto would be expanded to include species with hyaline conidia. Our multi-gene analyses (based on LSU, RPB2, ITS, β-tubulin and TEF1-α gene region) show that Phaeophleospora resides in Mycosphaerellaceae (Fig. 11). Phaeosphaeria I. Miyake, Bot.

Ramaley, Mycotaxon 61: 351 (1997); Fig. 202 Notes: Ramaley (1997) introduced the genus Phaeostagonospora with P. nolinae as the type species. At the same time, Ramaley (1997) introduced Paraphaeosphaeria nolinae A.W. Ramaley as the sexual morph of Phaeostagonospora nolinae based on occurrence of both fungi on same substrate. Câmara et al. (2003) transferred the sexual morph to the new genus, Phaeosphaeriopsis M.P.S. Câmara et al. and treated Phaeostagonospora as its asexual morph. However, this link was not proven based on either culture or molecular based methods. Phookamsak et al. (2014) and Wijayawardene et al. (2014c) accepted Phaeostagonospora as a distinct genus in Phaeosphaeriaceae, but this placement has not been confirmed by phylogenetic analyses.

However, both morphology and molecular data strongly supported the erection of a new genus, thus Wijayawardene et al. (2015) introduced Phragmocamarosporium.

Conidiophores hyaline, branched only at the base, septate, smooth, cylindrical, formed from the base of the inner wall of conidioma.

Conidia brown, muriform, 4–5 transversely septate, with 2–3 longitudinal septa, continuous, truncate at both ends, straight to curved, fusiform or ellipsoidal, smooth-walled (Sutton 1980; Mel’nik 1984; Bhat and Kendrick 1993). Type species: Phragmotrichum chailletii Kunze, Mykologische Hefte (Leipzig) 2: 84 (1823) Notes: The genus Phragmotrichum was introduced by Kunze and Schmidt (1823) based on P. chailletii as the type species. The conidial development of Phragmotrichum is fascinating as only a few coelomycetous genera have holothallic condiogenesis (Sutton 1980) although several hyphomycetous genera show such conidiogenesis (Seifert et al. 2011). However, Sutton and Pirozynski (1965), Sutton and Sandhu (1969) and Sutton (1977, 1980) accepted this genus as a coelomycete. Conidial development (arthric conidiogenesis) of Phragmotrichum is similar to Neozythia and Vouauxiella. A taxonomic key to distinguish Phragmotrichum and other related genera is provided under Cirrosporium. Besides the type species, Sutton (1980) accepted three species viz. P. pini (W.B. Cooke) B. Sutton & D.K. Sandhu, P. rivoclarinum (Peyronel) B. Sutton & Piroz. and P. platanoidis G.H. Otth. Since Sutton (1980), two species have been introduced i.e. P. vassiljevae Mel’nik (Mel’nik 1984) and P. andamanense Bhat et al. (Bhat and Kendrick 1993). Hence currently Phragmotrichum comprises six species. Piggotia Berk. & Broome, Ann. Mag. nat.

Hist., Ser. 2 7: 95 (1851) Notes: Berkeley and Broome (1851) introduced Piggotia with P. astroidea Berk. & Broome as the type species. However, Sutton (1980) listed only two species as accepted species. Further Sutton (1980) stated that all other species need to be revisited. Kirk et al. (2008) and Zhang et al. (2012) listed Piggotia as an asexual morph in Venturiaceae. However, Sutton (1980) stated Platychora ulmi (Schleich.) Pet. is the sexual morph of Piggotia ulmi.

Conidia ellipsoidal or cylindrical to fusiform, with slightly obtuse apex and base, aseptate, straight to slightly curved, hyaline to pale brown, smooth-walled, some species with lateral appendages or mucoid sheath (Sutton 1980; Nag Raj 1993; Van Niekerk et al. 2004; Rossman 2007; Miranda et al. 2012). Type species: Pilidiella quercicola (Oudem.) Petr., Beih. Reprium nov. Spec. Regni veg. 42(1): 462 (1927) [1926] Notes: Sutton (1980) reduced Pilidiella to synonym with Coniella as pycnidia, conidiogenesis and orientation of conidiophores were identical, except conidial pigmentation. von Arx (1957, 1981) used conidial pigmentation to distinguish Coniella and Pilidiella. However, Nag Raj (1993) accepted Pilidiella as a synonym of Coniella and rejected von Arx’s (1981) criteria of conidial pigmentation for distinguishing both genera. Nevertheless, Castlebury et al.

Sutton (1980) stated that Pilidiella castaneicola (as Coniella castaneicola) has pale brown conidia, but van Niekerk et al. (2004) mentioned both P. castaneicola and P. granati have hyaline conidia. Hence, van Niekerk et al. (2004) expanded the generic boundaries of Pilidiella to include ‘hyaline to dark brown conidia’. Our collection (Fig. 206) of P. castaneicola also has hyaline to subhyaline conidia while the collection of P. eucalyptorum has dark brown conidia (Fig. 207). However, Coniella also has dark brown conidia thus it is appropriate to rely on sequence data to distinguish Pilidiella species with dark brown conidia and Coniella species.

Zambettakis (1954) introduced several species but Sutton (1980) maintained the genus as monotypic. Buchanan (1987) transferred Diplodia canthiifolia Cooke & Massee to Placodiplodia and thus the genus comprises two species. In conidial morphology, Placodiplodia resembles Diplodia and Dothiorella. However, Placodiplodia has stromatic conidiomata, while both Diplodia and Dothiorella have pycnidial conidiomata. Nevertheless, phylogenetic studies are required to confirm the placement; Sequence data is unavailable. Pleoseptum A.W. Ramaley & M.E.

At the same time, Ramaley and Barr (1995) reported Camarosporium yuccaesedum as the asexual morph of Pleoseptum yuccaesedum as both morphs grow on same host material and they also proved the link by culture based methods.

Type species: Poropeltis davillae Henn., Hedwigia 43(6): 390 (1904); Fig. 213 Notes: Hennings (1904) introduced Poropeltis with P. davillae as the type species. Nag Raj (1977a) re-described and illustrated the type species. Sutton (1977, 1980) did not list Poropeltis in his checklist and monograph, respectively. Nevertheless, Kirk et al. (2008, 2013) listed it and thus we treat Poropeltis as a valid name. In morphology, Poropeltis resembles diplodia-like taxa, but lacks a median septum. Sequence data is unavailable, thus taxonomic placement is uncertain. Prillieuxina G.

Type species: Prosopidicola mexicana Crous & C.L. Lennox, Stud. Mycol. 50(1): 191 (2004); Fig. 215 Notes: Lennox et al. (2004) introduced the genus Prosopidicola with P. mexicana as the type species. In morphology, Prosopidicola resembles coniothyrium-like taxa i.e. which have brown pycnidia, reduced conidiophores and 0–1-septate conidia (Lennox et al. 2004; Verkley et al. 2004). However, phylogenetically, Prosopidicola cluster in distinct lineage from other coniothyrium-like taxa and resides in Diaporthales (Lennox et al. 2004).

Type species: Prosthemium betulinum Kunze, in Kunze & Schmidt, Mykologische Hefte (Leipzig) 1: 18 (1817) Notes: Schmidt (1817) introduced Prosthemium with P. betulinum as the type species. In morphology, Prosthemium closely resembles Asterosporium, thus recent studies rely on phylogenetic analyses (Kamiyama et al. 2009; Tanaka et al. 2010). Currently eleven epithets are listed in Index Fungorum (2016) however, Sutton (1980) listed only P. stellare Riess besides the type species. Since Sutton (1980), five species have been introduced viz. P. asterosporum T. Kowalski & Holdenr. (Kowalski and Holdenrieder 1996), P. canba Kaz.

(Kamiyama et al. 2009). Tanaka et al. (2010) showed that Asterosporium and Prosthemium are phylogenetically distinct and are accommodated in Diaporthales and Pleosporales respectively. At the same time, Tanaka et al. (2010) showed that the type species of Pleomassaria and Prosthemium (i.e. Pleomassaria siparia (Berk. & Broome) Sacc. and P. betulinum Kunze respectively) cluster in the same clade in Pleomassariaceae, Pleosporales. Hence, Wijayawardene et al. (2014c) proposed to adopt the older asexual typified generic name over the younger sexual typified name i.e. Prosthemium over Pleomassaria respectively. The adoption was accepted by Rossman et al. (2015). Pseudocamarosporium Wijayaw. & K.D. Hyde, Cryptog.

Mycol. 35(2): 191 (2014); Fig. 217 ≡ Hendersonia propinqua Sacc., Michelia 1(no. 5): 516 (1879) Notes: Wijayawardene et al. (2014d) showed that camarosporium-like taxa are polyphyletic in Pleosporales in their phylogenetic analyses. Camarosporium sensu stricto groups in Pleosporineae, while other camarosporiumlike taxa group as two other distinct clades in Didymosphaeriaceae, Massarineae (Wijayawardene et al. 2014e; Figs. 9 and 15). Hence, Wijayawardene et al. (2014d) introduced Pseudocamarosporium to place five taxa residing in Didymosphaeriaceae. Pseudocamarosporium is morphologically quite similar with Camarosporium sensu stricto and Paracamarosporium (in Didymosphaeriaceae). However, the latter genus has microconidia and paraphyses thus distinct from Pseudocamarosporium. Pseudodiplodia (P. Karst.) Sacc., Syll. fung. (Abellini) 3: 621 (1884) = Diplodia subgen.

Palm, Mycol. Res. 103(10): 1303 (1999) Notes: Crous and Palm (1999b) introduced Pseudohendersonia with P. proteae as the type species. In conidial morphology, Pseudohendersonia is similar with Homortomyces an Phragmocamarosporium. However, Homortomyces has paraphyses and in phylogenetic analyses Phragmocamarosporium resides in Lentitheciaceae (Wijayawardene et al. 2015 and see notes under Phragmocamarosporium). In this study we introduce the second species, but is slightly distinct from the type species of Pseudohendersonia as it has a smooth conidium wall. Currently, P. proteae lacks sequence data, but we prefer to maintain new collection under Pseudohendersonia until sequence of the type species is available.

However, Hendersonia Berk. was not listed as a valid name in any checklist or publication (Sutton 1977, 1980; Kirk et al. 2008, 2013). Based on morphology, our collection can be placed in Pseudohendersonia. Phylogenetic analyses show that Pseudohendersonia galiorum groups in Didymellaceae as a sister clade to Endocoryneum dactylidis (MFLUCC 14– 0461) (Fig. 9).

Type species: Readeriella mirabilis Syd. & P. Syd., Annls mycol. 6(5): 484 (1908); Fig. 223 Notes: Sydow and Sydow (1908) introduced Readeriella with R. mirabilis as the type species. Crous et al. (2004, 2007, 2009b) re-visited the genus based on both morphology and phylogenetic studies and Crous et al. (2009b) reduced Nothostrasseria Nag Raj and Cibiessia Crous under Readeriella. Crous et al. (2007, 2009b) recognized Readeriella as polyphyletic in Teratosphaeriaceae. Further, Crous et al. (2009b) transferred several species of Readeriella to Teratosphaeria which clustered in Teratosphaeria sensu stricto. Based on culture methods and molecular methods Crous et al. (2009b) confirmed that Readeriella often form Cibiessia synasexual morphs. Our phylogenetic analyses also agree with findings in Crous et al. (2009b) (Fig. 11). Readerielliopsis Crous & C.

(2015d) introduced Readerielliopsis with R. fuscoporiae as the type species. The morphology of Readerielliopsis deviates slightly from Readeriella sensu stricto which has solitary, non-papillate conidiomata and phialidic, non-percurrent conidiogenesis (Sutton 1980; Crous et al. 2015d). However, Readerielliopsis is phylogenetically distinct from Readeriella as it resides in Capnodiales, genera incertae sedis while latter genus resides in Teratosphaeriaceae (Fig. 11).

Conidiogenous cells holoblastic, doliiform to ampulliform, integrated, determinate, terminal or intercalary. Conidia ellipsoid, thickwalled, truncate at the base, aseptate, brown, thick-walled, verruculose (description modified from Sutton 1985). Type species: Rhizosphaerina variabilis B. Sutton, Sydowia 38: 336 (1986) [1985] Notes: Sutton (1985) introduced Rhizosphaerina with R. variabilis as the type species. Rhizosphaerina is characterized by sporodochial to acervular conidiomata, and thick-walled, brown conidia (Sutton 1985). In morphology, Rhizosphaerina resembles several genera such as Davisoniella and Fairmaniella, which are also reported on Myrtaceae. Sutton (1985) compared the morphology of Rhizosphaerina with Coniothyrium and Microsphaeropsis which also have brown conidia. However, Coniothyrium is restricted to 1-septate conidia (de Gruyter et al. 2013), while Microsphaeropsis has aseptate conidia (see notes under Coniothyrium) and both genera have pycnidial conidiomata. Sequence data is unavailable thus it is important to re-collect and carry out culture studies and phylogenetic studies to confirm its familial placement and generic boundaries. The taxonomic key can be used to distinguish Rhizosphaerina from related genera. Key to distinguish Rhizosphaerina from related genera 1.

Sacc., Michelia 2(no. 6): 8 (1880) Notes: Saccardo (1880) introduced Robillarda with R. sessilis as the type species. Robillarda has unique conidial morphology as it has only 1-septate conidia with apical appendages. Mycohypallage also has 1-septate, thick-walled conidia but, are paler in middle region (Sutton 1980). Nag Raj (1993) stated only Robillarda citricola Nag Raj, R. gossypii Erem. and R. sessilis (Sacc.) Sacc. have pale brown conidia, while other species have hyaline conidia. Crous et al. (2015a) showed that Robillarda belongs to Xylariales and clusters as a distinct clade, thus introduced Robillardaceae Crous.

Evans & Minter, Trans. Br. mycol. Soc. 84(1): 57 (1985) Facesoffungi number: FoF 01690; Fig. 230 Ascomycota, genera incertae sedis Endophytic or saprobic on Pinaceae (Gymnosperm). Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, immersed, solitary, globose, unilocular, hyaline, ostiolate. Ostiole papillate, circular. Conidiomata wall multi-layered, composed of brownwalled cells of textura angularis. Conidiophores branched, hyaline, thin-walled, smooth, constricted at the base. Conidiogenous cells holoblastic. Conidia circular to square in front view, elongated in end view, vertically flattened, consist of approximately 12 cells of cyanophilous, hyaline, thin-walled central cells, with approximately 36 brown walled exterior cells (Evans and Minter 1985; Dulymamode et al. 1998). Type species: Rubikia samsonii H.C. Evans & Minter, Trans. Br. mycol. Soc. 84(1): 57 (1985) Notes: Evans and Minter (1985) introduced Rubikia with R. samsonii as the type species. Rubikia is conspicuous among other coelomycetes as it has a pycnidial wall without pigmentation. Rubikia also has vertically flattened conidia, which is only similar to Nummospora, but the latter has only 6-celled conidia. In the original description, Evans and Minter (1985) did not describe the conidiogenous cells in detail. Hence, it is essential to re-collect and define well-established generic boundaries following phylogenetic data analyses.

However, Sutton (1980) studied the isotypes of both species and stated they were identical, thus the latter species was reduced under the type species. Hence, the genus remains monotypic and sequence data is unavailable thus taxonomic placement is uncertain.

(2013) predicted that Sclerostagonospora might have phaeosphaeria-like sexual morph. However, the type species lacks sequence data, thus the placement of Sclerostagonospora sensu stricto is uncertain. Sclerostagonospora arundinis Wijayaw., Camporesi, McKenzie & K.D. Hyde, sp. nov.

Sutton (current name Orphanocoela kranzii (B. Sutton) Nag Raj fide Nag Raj 1989) and S. sisyrinchii (Ellis & Everh.) B. Sutton. Sutton and Alcorn (1974) introduced S. spraguei B. Sutton & Alcorn and Sutton (1980) introduced S. mastigospora (Petr.) B. Sutton while treating Urohendersoniella Petrak and Brencklea Petrak as synonyms of Scolecosporiella. However, Nag Raj (1993) rejected synonyms in Sutton (1980) and treated Urohendersoniella and Brencklea as distinct genera. We agree with Nag Raj (1993) and it is appropriate to continue using separate names. The taxonomic key is provided under Brencklea to distinguish Brencklea, Scolecosporiella and Urohendersoniella.

(2011). However, Treigiene and Mel’nik (2002) introduced S. minkeviciusii Treigiene as a coelomycete, while Wijayawardene et al. (2013b) confirmed the species as a coelomycete, and found that S. minkeviciusii belongs to Phaeosphaeriaceae, Pleosporales, in their phylogenetic analyses. We confirm the type species of Scolicosporium, S. fagi as a coelomycete since it shows typical acervulus type conidioma (Fig. 234 c and d). Scyphospora L.A. Kantsch., Bolêz.

Sequence data is unavailable and thus taxonomic placement remains uncertain. Seimatosporiopsis differs from Seimatosporium in its concolorous conidia, while Seimatosporium has conidia with almost hyaline basal cells. Seimatosporiopsis B. Sutton et al. Trans. Br. mycol.

Scale bars: d = 60 μm, e = 100 μm, f–m = 20 μm Notes: Corda (1833) introduced Seimatosporium with S. rosae as the type species, while Sutton (1963, 1964, 1977, 1980), Shoemaker (1964a), Shoemaker and Muller (1964) and Nag Raj (1993) revisited the genus. Von Arx (1981) treated Bartalinia, Bartiloniopsis, Bleptosporium, Doliomyces and Hyalotia as synonyms of Seimatosporium. However, Nag Raj (1993) rejected these synonymies. We follow Nag Raj (1993) as his concept of Seimatosporium and other related genera has been shown to be more natural based on recent phylogenetic analyses (Barber et al. 2011; Tanaka et al. 2011; Norphanphoun et al. 2015; Senanayake et al. 2015). The heterogeneity of Seimatosporium was predicted by Sutton (1980) and Nag Raj (1993). Seimatosporium azaleae Okane et al. (Okane et al. 1996) grouped in Discosia sensu stricto (Tanaka et al. 2011). Barber et al. (2011) showed that Vermisporium H.J. Swart & M.A. Will. clusters in Seimatosporium sensu stricto thus it was treated as a synonym of Seimatosporium.

(1996) and Hatakeyama and Harada (2004) introduced Seimatosporium spp. with Discostroma sexual morphs. Barber et al. (2011), Tanaka et al. (2011), Ariyawansa et al. (2015a), Norphanphoun et al.

Scale bars: a = 30 μm, b, c = 10 μm (re-drawn from Morgan-Jones 1977) (2015) showed that both Seimatosporium and Discostroma clustered in a monophyletic clade and this agrees with our multi-gene analyses (Fig. 16). However, the type species of Discostroma, D. rehmii lacks sequence data, thus we prefer to maintain both generic names. Recently, Norphanphoun et al. (2015) designated the epitype for Seimatosporium rosae and provided a comprehensive phylogenetic background of the genus.

Type species: Seiridium marginatum Nees, System der Pilze und Schwämme: 22: (1816–1817) Notes: Nees (1817) introduced Seiridium with S. marginatum as the type species. Guba (1961), Shoemaker et al. (1966), Sutton (1969a, 1980) and Nag Raj (1993) revisited the genus with taxonomic notes. Nag Raj (1993) stated that Seiridium has sexual morphs in Lepteutypa and Blogiascospora. Jeewon et al. (2002) showed that Seiridium cardinale (W.W. Wagener) B. Sutton & I.A.S. Gibson and S. cupressi (Guba) Boesew. clustered with Lepteutypa cupressi (Nattrass et al.) H.J. Swart in their phylogenetic analyses. They also showed Seiridium could be accommodated in Amphisphaeriaceae. However, Maharachchikumbura et al. (2015) and Senanayake et al. (2015) showed that Seiridium has distinct lineage in Amphisphaeriales and clustered in Pestalotiopsaceae (Fig. 16). Seiridium spp. have been reported as pathogens of cypress (Cupressus spp.) (Graniti 1998). Barnes et al. (2001) identified three species, S. cardinale, S. cupressi and S. unicorne based on phylogenetic analyses of β-tubulin and histone H3 gene regions. Krokene et al. (2004) confirmed the findings of Barnes et al. (2001) by PCR-RFLP based diagnostic techniques. Seiridium pseudocardinale Wijayaw., Camporesi, McKenzie & K.D. Hyde, sp. nov.

Notes: Our collection from Cupressus glabra morphologically resembles Seiridium species (Sutton 1980; Nag Raj 1993), and in sequence analyses, it groups with Seiridium Fig. 241 RAxML tree generated from ITS sequences of Seiridium strains in GenBank.

The scale bar represents the expected number of changes per site. The tree was rooted to Truncatella angustata (ICMP 7062) Fungal Diversity sensu stricto (Fig. 241). Two Seiridium spp. have been reported on Cupressus spp. (Sutton 1980; Farr and Rossman 2016). Our collection is morphologically distinct from these two species and hence it is introduced as a new species. The key below distinguishes species described from Cupressus spp. 1.

Conidia clavate or cylindrical, apex obtuse, base truncate, pale brown, straight or bent some what irregularly, up to 8-septate, continuous, thin-walled, smooth, eguttulate or guttulate, with a gelatinous cap that may become partially everted (Sutton 1980; Nag Raj 1993; Lee and Crous 2003; Taylor and Hyde 2003; Crous et al. 2014b, 2015a). Type species: Septoriella phragmitis Oudem., Ned. kruidk. Archf, 2 sér. 5: 54 (1889) Notes: Oudemans (1889) introduced Septoriella with S. phragmitis as the type species. Sutton (1977) listed the synonyms and Sutton (1980) provided taxonomic notes. Nag Raj (1993) re-visited the genus and provided illustrations and descriptions for six species. Since Nag raj (1993), several species have been introduced by Sutton and Mel’nik (1999), Kohlmeyer and Volkmann-Kohlmeyer (2000), Lee and Crous (2003), Taylor and Hyde (2003), Andrianova and Minter (2007) and Crous et al.

Type species: Shawiella grevilleae Hansf., Proc. Linn. Soc. N.S.W. 82: 226 (1957) Notes: Hansford (1957) introduced Shawiella based on S. grevilleae as the type species. Sutton (1980) accepted only one species and the genus remains monotypic. However, Sutton (1980) did not provide an illustration. Sequence data is unavailable thus taxonomic placement is uncertain.

Asexual morph: Conidiomata pseudostromatic, solitary to gregarious, immersed, peridermal to subperidermal, globose to conical, unilocular, dark brown, papillate ostiole, central, circular. Conidiomata wall outer layer composed of thick-walled, very dark brown occluded cells, lateral and basal walls composed of peridermal cells and thickwalled, brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, annellidic, ampulliform, doliiform or cylindrical, discrete, indeterminate, hyaline, often thick and smooth-walled. Conidia fusiform, base truncate, apex obtuse, with several transverse and lateral distosepta, continuous, smooth and thick-walled; initially enveloped in a gelatinous sheath, depressed at the apex, at maturity remaining as a basal lateral sheath (Petrak 1961; Sutton 1980; Barr 1982; Tanaka et al. 2005).

Club 10(7): 76 (1883) = Shearia magnoliae (Shear) Petr., Annls mycol. 22(1/2): 180 (1924) Notes: Petrak (1924) introduced Shearia with S. magnoliae as the type species. However, Sutton (1980) treated S. formosa (≡ Stegonsporium formosa) as the type species and listed Shearia magnolia as a synonym. Currently, four species epithets are listed in Index Fungorum (2016), but Sutton (1980) accepted only one species. Fungal Diversity Following Shear (1902), Sutton (1980) stated that Pleomassaria magnolia Shear is the sexual morph of Shearia formosa based on co-occurrence of both states on same host material. This was accepted by Barr (1982) and Tubaki et al. (1983). Tanaka et al. (2005) reported Pleomassaria maxima Ellis & Everh. as the sexual morph of S. fusa (Berk. & M.A. Curtis) M.E. Barr based on cultural methods, however, Pleomassaria sensu stricto was linked with Prosthemium sensu stricto (Tanaka et al. 2010). The link between Shearia sensu stricto and Pleomassaria sensu lato is not confirmed by sequence data analyses. Further, taxonomic placement of Shearia is uncertain as sequence data is unavailable.

N.S.W. 79(3–4): 135 (1954) Notes: Swart and Walker (1988) introduced Sonderhenia to accommodate Hendersonia eucalyptorum and H. eucalypticola A.R. Davis. The genus Hendersonia was treated as doubtful by Sutton (1977, 1980). Kirk et al. (2008, 2013) also did not recognize Sonderhenia as a valid name. In some morphological characters, Sonderhenia resembles Macrodiplodiopsis and Stilbospora as they also have ‘cylindrical, fusiform, distoseptate conidia’. However, Macrodiplodiopsis has a conspicuous gelatinous sheath around the conidium and Stilbospora has paraphyses in the conidioma and thus Sonderhenia can easily be distinguished.

Conidiogenous cells holoblastic, proliferating at same level to form periclinal thickenings or rarely proliferating percurrently, cylindrical to broad lageniform, indeterminate, discrete or integrated, hyaline, smooth. Conidia oblong to subcylindrical, apical end rounded, with a truncate base, 1-septate, continuous or occasionally slightly constricted at septum, brown, moderately thickwalled, externally smooth, internally finely verruculose (Phillips et al. 2008, 2013). Type species: Spencermartinsia viticola (A.J.L. Phillips & J. Luque) A.J.L. Phillips et al., Persoonia 21: 51 (2008) ≡ Botryosphaeria viticola A.J.L. Phillips & J. Luque, Mycologia 97(5): 1118 (2006) [2005] Notes: Phillips et al. (2008) introduced Spencermartinsia to accommodate Botryosphaeria viticola which has dothiorellalike asexual morphs. Phillips et al. (2013) maintained the genus as monotypic although several strains grouped in the Spencermartinsia clade. Further, Phillips et al. (2013) mentioned that the asexual morph is common in nature compared to sexual morph. In conidial morphology, Spencermartinsia resembles Dothiorella, as ‘conidia become brown and 1-septate while attached to the conidiogenous cells before dehiscence’ (Phillips et al. 2013). However, Spencermartinsia has ascospores with a conspicuous apiculus, while ascospores of Dothiorella lack an apiculus (Phillips et al. 2013). Phylogenetically, Dothiorella and Spencermartinsia show distinct lineages in Botryosphaeriaceae (Phillips et al. 2008, 2013; Liu et al. 2012; Fig. 9 and 10), thus it is more reliable to rely on sequences data to distinguish both genera.

(2013) for synonyms Notes: Saccardo (1880) introduced Sphaeropsis with S. visci as the type species. More than 600 names are listed in Index Fungorum (2016), but most are based on host association (Phillips et al. 2013). Phillips et al. (2008) showed that the cultures of Phaeobotryosphaeria visci, produce Sphaeropsis visci asexual morphs. Moreover, Phillips et al. (2008, 2013) showed Sphaeropsis and Phaeobotryosphaeria clustered in Botryosphaeriaceae in a monophyletic clade in their phylogenetic analyses. Thus, Phillips et al. (2013) accepted that Phaeobotryosphaeria represents sexual morph of Sphaeropsis. Phillips et al. (2013) proposed to adopt older asexual name, Sphaeropsis, over the younger sexual typified name. Our phylogenetic analyses also agree with results in Phillips et al. (2013) (Fig. 10). Key to distinguish Avettaea, Aplosporella and Sphaeropsis 1.

Conidia obovoid to clavate, with several transverse and longitudinal distosepta, cell lumina reduced, brown, smooth, obtuse at the apex, truncate at the base (Sutton 1980; Warmelo and Sutton 1981; Voglmayr and Jaklitsch 2008, 2014). Type species: Stegonsporium pyriforme (Hoffm.) Corda, Icon. fung. (Prague) 3: 23 (1839); Fig. 250 Notes: Opiz (1827) introduced Stegonsporium with S. pyriforme as the type species. Sutton (1975a, 1980) and Warmelo and Sutton (1981) re-visited the genus and compared it with other related genera. Voglmayr and Jaklitsch (2008, 2014) comprehensively addressed the genus with both morphology and molecular analyses. Stegonsporium is similar to Myxocyclus in conidial morphology. However, spores of Myxocyclus are often enclosed in a gelatinous sheath, a feature that is lacking in Stegonsporium. Voglmayr and Jaklitsch (2008, 2014) accepted that Stegonsporium had prosthecium-like sexual morphs. Several Prosthecium species grouped with Stegonsporium sensu stricto and these were transferred to Stegonsporium as new combinations (Voglmayr and Jaklitsch 2014). Moreover, Voglmayr and Jaklitsch (2014) showed Stegonsporium groups as a distinct clade in Stilbosporaceae, Diaporthales and this agrees with our phylogenetic analyses (Fig. 12).

Scale bars: a = 100 μm, b, c = 20 μm (redrawn from Sutton 1980) Sutton (1964) and Petrak and Sydow (1927) treated Stenocarpella macrospora and S. maydis as Diplodia and Macrodiplodia respectively. However, Sutton (1977, 1980) transferred both species to Stenocarpella. Both Stenocarpella macrospora (= Diplodia macrospora) and S. maydis Fungal Diversity (= D. maydis) are well known pathogens of corn, the causal agent of stalk and ear rot and leaf spot (Latterell 1983; da Silva Siqueira et al. 2014). Based on LSU sequence data, Crous et al. (2006a) showed that Stenocarpella sensu stricto has a distinct phylogenetic placement from Diplodia sensu stricto and is accommodated in Diaporthales. Lamprecht et al. (2011) and our phylogenetic analyses also agree with Crous et al. (2006a) and further confirm the placement in Diaporthaceae (Fig. 12).

Type species: Stevensonula ciliata Petr., Sydowia 6(1–4): 2 (1952); Fig. 254 Notes: Petrak (1952) established the genus with S. ciliata as the type species. Sutton (1980) provided taxonomic notes and compared the genus with conidiomata of Nanoschema. However, Nanoschema has ellipsoid, 1-septate, eguttulate, hyaline conidia and is thus distinct from Stevensonula. Sutton (1980) and Nag Raj (1993) retained the genus as monotypic.

Hughes (1958) determined Coryneum effiguratum as an older name for the taxon and transferred it to Stigmella as S. effigurata and treated S. dryina as a synonym of S. effigurata (Hughes 1958). Sutton (1977, 1980) accepted the findings of Hughes (1958). Bagyanarayana et al. (1992) and Wang et al. (2012) have introduced S. tirumalensis Bagyan. et al. and S. lycii X.R. Chen & Y. Wang.

Lectotype species: Stilbospora macrosperma Pers., Syn. Meth. Fung. (Göttingen) 1: 96. 1801, fide Clements and Shear (1931); Fig. 255 Notes: Persoon (1795) introduced Stilbospora with S. macrosperma. However, Kirk et al. (2008, 2013) and Voglmayr and Jaklitsch (2014) accepted Stilbospora Pers. (1794) as the legitimate name. Sutton (1980) stated, ‘more than 60 taxa have been described in the genus so far and the majority of these have not been re-examined’. Taylor and Crous (2000), Marincowitz et al. (2008) and Voglmayr and Jaklitsch (2014) have re-visited the genus and introduced several taxa. Crous et al. (2012b) showed that Stilbospora macrosperma belongs in Diaporthales. Voglmayr and Jaklitsch (2014) treated Prosthecium ellipsosporum Fresen. the type species of Prosthecium as a synonym of Stilbospora macrosperma. Voglmayr and Jaklitsch (2014) also showed several Prosthecium spp. clustered in Stilbospora sensu stricto and thus transferred them to Stilbospora. Based on molecular data analyses, Voglmayr and Jaklitsch (2014) and Maharachchikumbura et al. (2015) showed Stilbospora and Stegonsporium have distinct phylogenetic lineages in Diaporthales, thus they re-instated Stilbosporaceae to accommodate these genera. Our phylogenetic analyses agree with Voglmayr and Jaklitsch (2014) and confirm the placement of Stilbospora sensu stricto as a distinct clade in Diaporthales (Fig. 12). Sulcatispora Kaz. Tanaka & K.

Tanaka & K. Hiray. and both species are reported as holomorph. Sulcatispora resembles Sclerostagonospora, but the latter genus showed phylogenetic lineages in Pleosporineae, Pleosporales and may have phaeosphaeria-like sexual morphs. (Quaedvlieg et al. 2013). In their phylogenetic study, Tanaka et al. (2015) showed that Sulcatispora has distinct lineage in Massarineae, thus they introduced Sulcatisporaceae Kaz. Tanaka & K. Hiray. These results were also confirmed by our phylogenetic analyses (Fig. 15).

Camarosporium, Neocamarosporium, Paracamarosporium, Pseudocamarosporium and Xenocamarosporium (Crous et al. 2013, 2015d; Wijayawardene et al. 2014a, d). However, only Paracamarosporium also has paraphyses, but it distinct from Suttonomyces in phylogeny as it resides in Didymosphaeriaceae and also forms microconidia in culture. Teratosphaeria Syd. & P. Syd., Annls mycol. 10(1): 39 (1912) Facesoffungi number: FoF 01713; Fig. 258 = Colletogloeopsis Crous & M.J. Wingf., Can. J. Bot. 75(4): 668 (1997) = Kirramyces J. Walker, B. Sutton & Pascoe, Mycol. Res. 96(11): 919 (1992) Dothideomycetes, Dothideomycetidae, Capnodiales, Teratosphaeriaceae Endophytic, saprobic or pathogenic on various substrates of range of host plants. Sexual morph: see Crous et al. (2009b). Asexual morph: Conidiomata acervuli to pycnidial, subcuticular, erumpent, dark brown to black. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic and percurrent, doliiform to subcylindrical or irregular, thick-walled. brown, verruculose. Conidia subcylindrical to ellipsoidal, or cylindrical to obclavate, straight to curved, apex obtuse, base truncate, aseptate, medium brown, verruculose (Walker et al. 1992; Crous and Wingfield 1997; Crous et al. 2009b, 2011d; Andjic et al. 2007a, b). Type species: Teratosphaeria fibrillosa Syd. & P. Syd., Annls mycol. 10(1): 40 (1912) Notes: Crous et al. (2009b) accepted that Teratosphaeria sensu stricto has Colletogloeopsis and Kirramyces asexual morph. Thus, Wijayawardene et al. (2014c) proposed to adopt Teratosphaeria over Colletogloeopsis and Kirramyces. In our phylogenetic analyses of Capnodiales, Teratosphaeria sensu stricto consists of both Colletogloeopsis and Kirramyces (Fig. 11).

Crypt. Flandres (Paris) 1: 354 (1867) = Tiarospora westendorpii Sacc. & Marchal, Revue mycol., Toulouse 7(no. 26): 148 (1885) Notes: Saccardo and Marchal (1885) established Tiarospora with T. westendorpii as the type species. However, Höhnel (1918) found Sphaerella perforans is the oldest name for the taxon and thus transferred it to Tiarospora as T. perforans. Pirozynski and Shoemaker (1971), MorganJones et al. (1972c), Sutton (1971, 1980) and Nag Raj (1993) accepted this adoption and treated Tiarospora westendorpii as a synonym of T. perforans. Beside the type species, Sutton (1980) accepted only T. deschampsiae Krusch. Chlebicki (2002) introduced Tiarospora pirozynskii Chleb. and thus the genus now comprises three species. Sequence data is unavailable thus taxonomic placement is uncertain. Toxosporiella B. Sutton, Trans. Br. mycol.

Asexual morph: Conidiomata pycnidial, solitary, immersed, globose, unilocular, dark brown, ostiolate. Ostiole slightly papillate, central, circular. Conidiomata wall composed of thick-walled, brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, ampulliform, lageniform or cylindrical, discrete, hyaline. Conidia ellipsoid, obtuse apex, truncate base, with 3transverse septate, median cell dark brown, apical and basal cell with oblique septum (description modified from Sutton 1986). Type species: Toxosporiella bactrodesmioides B. Sutton, Trans. Br. mycol. Soc. 86(1): 16 (1986) Notes: Sutton (1986) introduced Toxosporiella with T. bactrodesmioides as the type species. Toxosporiella comprises one species and is characterised by versicoloured conidia, Fungal Diversity hence distinct from other genera. However, Toxosporiella resembles the conidial morphology of Versicolorisporium (Hatakeyama et al. 2010) but latter genus lacks a single oblique septum in the apical and basal cells. Sequence data is unavailable in GenBank thus taxonomic placement is uncertain. Toxosporiopsis B. Sutton & Sellar, Can. J. Bot. 44(11): 1505 (1966) Facesoffungi number: FoF 01716; Fig. 261 Ascomycota, genera incertae sedis Endophytic or saprobic on various substrates of a range of host plants. Sexual morph: Undetermined. Asexual morph: Conidiomata stromatic, immersed, subperidermal, solitary or confluent, irregular in shape, irregularly locular, hyaline to pale brown. Conidiomata wall composed of small-celled, thin-walled, hyaline to pale brown cells of textura angularis. Conidiophores hyaline, branched at the base, septate, smooth. Conidiogenous cells holoblastic, determinate, integrated or discrete, cylindrical, hyaline, smooth. Conidia broadly fusiform, base truncate, 3-septate, septa dark brown, continuous or slightly constricted, thick and smoothwalled, apical and basal cells thinner-walled and paler; mucoid cap at the apex of developing conidium (Sutton 1980; Sutton and Dyko 1989; Nag Raj 1993; Wu 1993). Type species: Toxosporiopsis capitata B. Sutton & Sellar, Can. J. Bot. 44(11): 1507 (1966); Fig. 263 Notes: Saccardo and Marchal (1966) established Toxosporiopsis with T. capitata as the type species. Sutton and Dyko (1989) and Wu (1993) added two more species, T. macrosperma (Cavara) B. Sutton & Dyko and T. sinensis W.P. Wu, respectively. Nag Raj (1993) re-described the genus and illustrated the type species. However, Nag Raj (1993) listed T. macrosperma as an ‘unexamined taxon’ and mentioned it differs from type species as it has conidia with paler and verruculose apical and basal cells. Nevertheless, Wu (1993) treated T. macrosperma as an accepted species of Toxosporiopsis and thus we accept three species. Sequence data is unavailable, thus, taxonomic placement is uncertain.

Conidiophores lining the inner cavity, subcylindrical, hyaline, smooth, reduced to conidiogenous cells or branched, 1–3-septate, with conidiogenous cells terminal and lateral. Conidiogenous cells hyaline to pale brown, smooth, thin-walled, ampulliform to subcylindrical; apex with periclinal thickening, but at times also with 1–2 percurrent proliferations. Conidia rounded lobes, tapering towards a truncate base, aseptate, widest at apex, brown, smooth, with three lateral (modified description from Crous et al. 2012d) Type species: Trinosporium guianense Crous & Decock, Persoonia, Mol. Phyl. Evol. Fungi 28: 169 (2012) Notes: Crous et al. (2012d) introduced Trinosporium with T. guianense as the type species. In morphology, Trinosporium resembles Readeriella, which is a wellestablished genus in Teratosphaeriaceae (Crous et al. 2009b), but the former resides in Leotiomycetes, genera incertae sedis (Fig. 9). Further, Crous et al. (2012d) compared Tri n os p o ri um w i t h Tr i b o l o s po r a D . A . R e i d a n d Trigonosporium Tassi and both genera have hyaline conidia (Sutton 1980).

Conidiomata wall thick, wall at the base composed of thin-walled, pale brown to subhyaline cells of textura angularis, at the sides and above walls composed of thickwalled, dark brown cells of textura angularis to textura intricata. Conidiophores cylindrical, hyaline, branched, septate near the base and above, formed from the inner cells of the conidiomata. Conidiogenous cells holothallic, integrated, hyaline, smooth, cylindrical. Conidia regularly oblong, truncate at each end, arthric, produced in long, branched chains with the youngest conidia at the base, pale brown, smooth-walled, often guttulate, aseptate (Sutton 1980). Type species: Trullula oreoselini Ces., Bot. Ztg. 10: 287 (1852) Notes: Cesati (1852) introduced Trullula with T. oreoselini as the type species. Sutton (1980) stated that the characters of the genus are not well known. Hence, further collections and morphological and molecular studies are essential for better understanding of the genus. Fungal Diversity GenBank has sequence data of Trullula melanochlora (CBS 138861 fide Crous et al. 2014c) and according to our analyses it is accommodated in Leotiomycetes, genera incertae sedis (Fig. 9).

Nat., Bot., sér. 3 5: 285 (1846) Notes: Steyaert (1949) established Truncatella with T. truncata as the type species. Sutton (1980) stated Truncatella angustata (Pers.) S. Hughes (≡ Stilbospora angustata Pers.) as the type species, while listing Truncatella truncata as its synonym. However, Nag Raj (1993) used Truncatella truncata as the type species, but we prefer to use the name based on the oldest name i.e. Truncatella angustata. Sutton (1980) compared the previous taxonomic works by Steyaert (1949) and Guba (1961) on Truncatella. Since Sutton (1980), several species have been introduced and summarized in Table 7. Lee et al. (2006) showed Truncatella spp. group with Bartalinia spp. and form a distinct clade in Amphisphaeriaceae. However, the clade actually comprises two distinct clades. The first clade comprises new collections in Lee et al. (2006) with T. hartigii (Tubeuf) Steyaert, while the second sub-clade comprises T. angustata (Pers.) S. Hughes and species of Bartalinia Tassi. Senanayake et al. (2015) and our results also agree with findings in Lee et al. (2006) and Truncatella is treated as a member in Bartaliniaceae. Tunicago B. Sutton & Pollack, Can. J.

In conidial morphology, Uniseta resembles Nagrajomyces, but the latter genus has muriform conidia with single, unbranched apical appendages, while Uniseta has 1-septate conidia with a single, unbranched apical appendage. Nag Raj (1993) mentioned Uniseta has a sexual morph in Cryptodiaporthe Petr. However, this link was not confirmed by culture or phylogenetic methods.

Sutton (1980) and Nag Raj (1993) re-visited the genus and provided detailed taxonomic notes. There are six epithets listed in Index Fungorum (2016), but Sutton (1980) and Nag Raj (1993) accepted only five species including the type species, while U. mysorensis Nag Raj & W.B.

However, Sutton (1977, 1980) and Kirk et al. (2013) listed Vanderystiella as a valid genus, while listing Deightonia as its synonym. We also prefer to follow Sutton (1977, 1980) as Vanderystiella is the oldest name. The genus remains monotypic and sequence data is unavailable thus taxonomic placement is uncertain.

Fungal Diversity Verrucoconiothyrium resembles with Coniothyrium but is distinct as the former genus has verruculose conidial walls. Phylogenetically both genera are distinct as Verrucoconiothyrium resides in Didymosphaeriaceae, while Coniothyrium resides in Coniothyriaceae (Figs. 9 and 15). Versicolorisporium Sat.

Conidiomatal wall composed of vertically orientated rectangular, pale brown-walled cells of textura angularis; wall at the base flattened, poorly developed, composed of polygonal cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, Fig. 273 Versicolorisporium triseptatum (Material examined: Japan, Aomori, Gonohe, Asamizu, on dead culms of Pleioblastus, 2 December 2003, K. Tanaka, N. Nakagawara, and S. Hatakeyama, HHUF 28815, holotype; single conidium isolate from the holotype = JCM 14775). ampulliform to cylindrical, unbranched, determinate, bearing a single terminal conidium, formed from the inner layer of the conidiomatal wall. Conidia obovoid, apex rounded, base truncate, 3-septate, with a submedian primary septum, smooth-walled; apical cell pale brown; second cell from the apex dark brown; third cell pale brown; basal cell hyaline (description modified from Hatakeyama et al. 2008). Type species: Versicolorisporium triseptatum Sat. Hatak. Et al., Mycoscience 49(3): [211] (2008); Fig. 273 Notes: Hatakeyama et al. (2008) established Versicolorisporium with V. triseptatum as the type species. Mega blast result of LSU nrDNA sequences show the type species resides in Pleosporales, Dothideomycetes (Hatakeyama et al. 2008). In shape of conidia, Versicolorisporium is similar to Phragmocamarosporium (Wijayawardene et al. 2015), but the latter taxon has concolorous conidia, while the former has versicoloured conidia. Versicolorisporium also resembles Toxosporiella, but the latter genus has an oblique septum in the basal cell (Sutton 1986).

Conidiogenous cells holothallic, integrated or discrete, determinate, hyaline to brown, verrucose. Conidia arthric, cylindrical or long cuneiform, both ends truncate, but apical conidium with obtuse apex, brown or dark brown, aseptate, produced in simple unbranched basipetal chains (Morgan-Jones 1977; Sutton 1980; Diederich 2003).

Fr. 54: 697 (1907) Notes: Petrak and Sydow (1927) described Vouauxiella for the two species V. verrucosa and V. lichenicola (Linds.) Petr. & Syd., both growing on Lecanora species. Morgan-Jones (1977) illustrated and re-described the type species, while Sutton (1980) added a third lichenicolous species, V. pithospora (Cavalc. & A.A. Silva) B. Sutton. Conidial development (arthric conidiogenesis) of Vouauxiella is similar to Phragmotrichum, Neozythia and Cirrosporium. A taxonomic key to distinguish Vouauxiella and related genera is provided under Cirrosporium. Sequence data is unavailable thus taxonomic placement is uncertain.

Hyde & Borse, the type species of Biatriospora in our phylogenetic analyses (Fig. 9). Hence, we conclude that Biatriosporaceae comprises two genera, Biatriospora and Versicolorisporium. Further, we predict that Versicolorisporium might represent the asexual morph of Biatriospora.

Type species: Wojnowiciella eucalypti Crous et al., Persoonia, Mol. Phyl. Evol. Fungi 335: 201 (2015) Notes: Crous et al. (2015d) introduced Wojnowiciella with W. eucalypti Crous et al. as the type species. Wojnowiciella resembles Wojnowicia in conidial morphology, but the latter genus has papillate conidiomata, with setae (Sutton 1980). Crous et al. (2015d) proposed to place Wojnowicia viburni Wijayaw. et al. (Wijayawardene et al. 2013b) under Wojnowiciella as it has conidiomata without setae. Moreover, Crous et al. (2015d) reported microconidia from Fungal Diversity W. eucalypti, but Wijayawardene et al. (2013b) did not report microconidia from the culture.

Type species: Xenocamarosporium acaciae Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol. Fungi 335: 185 (2015) Notes: The genus Xenocamarosporium was introduced by Crous et al. (2015d) with X. acacia as the type species. Xenocamarosporium morphologically resembles Melnikia and Pseudohendersonia. However, these genera are phylogenetically distinct from Xenocamarosporium which resides in Didymosphaeriaceae (Fig. 15). Moreover, Pseudohendersonia has conidia with rounded ends, while Xenoconiothyrium Crous & Marinc., Persoonia, Mol. Phyl. Evol.

Fungi 27: 42 (2011); Fig. 277 Notes: Crous et al. (2011c) introduced Xenoconiothyrium with X. catenatum as the type species. However, Crous et al. (2011c) only mentioned the conidiomatal type as pycnidial but did not describe it in detail. Phylogenetically, Xenoconiothyrium is distinct from Coniothyrium sensu stricto (in Pleosporineae, Coniothyriaceae) and resides in Teratosphaeriaceae, Capnodiales (Crous et al. 2011c; Fig. 11).

Nag Raj (1993) also introduced a second species, hence the genus comprises two species. Xepiculopsis morphologically resembles Xepicula and Hymenopsis. The taxonomic key below can be used to distinguish Xepiculopsis from related genera. truncate base, hyaline, with or without cellular, unbranched, single appendage (Nag Raj 1993; Matsushima 1996; Crous et al. 2014b) Type species: Zetiasplozna unicolor (Berk. & M.A. Curtis) Nag Raj, Coelomycetous Anamorphs with Appendagebearing Conidia (Ontario): 1002 (1993); Fig. 280 Notes: Nag Raj (1993) introduced Zetiasplozna with Z. unicolor as the type species. At the same time, Nag Raj (1993) accepted three further species, Z. cordylines (Speg.) Nag Raj, Z. heteromorpha (Thüm.) Nag Raj and Z. thuemenii (Speg.) Nag Raj. Matsushima (1996) and Crous et al. (2014b) introduced Z. caffra Matsush. and Z. acaciae Crous respectively. In conidial morphology, Zetiasplozna is similar to Bartalinia, but the latter genus has branched apical appendages, while the former has unbranched apical appendages. Based on mega blast search of ITS and LSU sequence data of Z. acaciae, Crous et al. (2014b) stated it belongs to Amphisphaeriaceae. Our phylogenetic analyses indicate that Z. acaciae belongs in Bartaliniaceae and clusters as the sister clade to Morinia sensu stricto. Poorly known genera Key to Xepiculopsis and related genera 1 .

Psammina Sacc. & M. Rousseau ex E. Bommer & M. Rousseau, Bull. Soc. R. Bot. Belg. 29(1): 295 (1891) Notes: Sutton (1980) treated Psammina as a coelomycetous genus with ‘acervular’ conidiomata. However, Hawksworth (1979) mentioned that the type species of Psammina, P. bommerae Rouss. & Sacc show ‘a rudimentary stroma’ hence subsequent publications by Earland-Bennett and Hawksworth (1999, 2005) treated Psammina as a hyphomycetous genus. Psammina species are reported as lichenicolous, algicolous and lichen-forming taxa (Earland-Bennett and Hawksworth 1999, 2005). Sclerodothiorella Died., Krypt.-Fl. Brandenburg (Leipzig) 9: 299 (1912). Notes: Sutton (1977) listed Sclerodothiorella in his list of generic names but stated the type species as Dothiorella populina P. Karst. Sclerodothiorella is listed as a synonym of Dothiorella in Species Fungorum (2016). However, Kirk et al. (2008) recognized Sclerodothiorella as a distinct genus, while neither Sutton (1980) nor Kirk et al. (2013) listed it as a distinct genus. Microdiplodia Allesch., Rabenh.

Zhuang Johnston et al. 2014 Coelomycetous stage is in bold; (Hn) = with hyaline conidia for Coelomycetes’ thus Sutton (1980) did not list Microdiplodia as a recognized genus. Crous and Groenewald (2006) introduced Microdiplodia hawaiiensis based on its small, brown, 1-septate conidia, and their occurrence on stems and branches. However, Damm et al. (2008) showed M. hawaiiensis clusters with Paraconiothyrium sensu stricto thus transferred to Paraconiothyrium. Hence, the generic stability of Microdiplodia is problematic thus need further re-collections are needed with molecular based studies. Discussion Hidden species and genera The number of fungal species was estimated as 1.5 million by Hawksworth (1991). However, the introduction of molecular techniques, including phylogenetic analyses, since 1990 the number of new taxa has increased dramatically. O’Brien et al. (2005) and Blackwell (2011) estimated the number of global fungal species to be around 5.1 million, while Hawksworth (2012) stated that it would be appropriate to use ‘at least 1.5, but probably as many as 3 million’. Nevertheless, Hawksworth (2012) mentioned that the number of fungi will increase with the extensive taxonomic studies in tropics and utilization of sequence based taxonomy as well. Kirk et al. (2008) stated that there are 1000 genera of coelomycetes comprising over 7000 known species. However, recent molecular based studies showed many species are actually species complexes comprising cryptic species, i.e. species identical in morphology and thus hard to distinguish, but resolved as distinct species based on sequence data (Alves et al. 2008). For example, several ‘species’ of Colletotrichum (Hyde et al. 2009a, b; Damm et al. 2012, 2013, 2014; Liu et al. 2013), Diaporthe (Udayanga et al. 2012), Diplodia (Alves et al. 2014), Lasiodiplodia (Alves et al. 2008), Pestalotiopsis (Maharachchikumbura et al. 2014) have been shown to be species complexes. Furthermore, several genera that were treated as polyphyletic e.g., Camarosporium, Coniothyrium, Phoma, etc. are now known to be monophyletic, and at the same time new genera have been introduced (Verkley et al. 2004, 2014; de Gruyter et al. 2009, 2013; Wijayawardene et al. 2014e; Crous et al. 2015d). Hence the number of genera and species of coelomycetes is expected to increase dramatically over the coming decades. Identification, detection methods and quarantine needs Several coelomycetous genera are well known plant pathogens and it is essential within many disciplines and industries such as agriculture, horticulture, plant breeding and export– import industry to be able to reliably identify the species. Traditionally pathogens were identified based on characters Fungal Diversity of disease material (Hyde et al. 2010) and culture based morphological methods (Lievens and Thomma 2005). However, as many of the pathogens are species complexes (Damm et al. 2012; Alves et al. 2008, 2014; Hyde et al. 2014) the use of traditional methods has become questionable (Abd-Elsalam et al. 2010). Hence, modern techniques including molecular detection methods and polyphasic approaches are strongly recommended (Cai et al. 2009; Aveskamp et al. 2010; Hyde et al. 2014). Precise identification is essential for producers or farmers, exporters and quarantine authorities to avoid unnecessary losses (Meyer et al. 2012). Fluorescence in situ hybridisation (FISH), DNA array technology and Multiplex tandem PCR are some modern detecting techniques used in fungal identification. At the same time, it is essential to maintain viable living cultures of plant pathogenic species that have economic and quarantine importance. Maintaining such a culture collection is important as the cultures can be used as standards, for improving disease resistant plants in breeding programs (AbdElsalam et al. 2010). Natural classification and 1 F = 1 N Since most of the important genera show pleomorphism i.e. ‘they occur as sexual and asexual states through their life history, but may be separated in time and space’ (Kendrick 1979), Saccardo (1904) proposed the dual system of fungal nomenclature. However, proposing two or more names for different states has caused confusion, misunderstanding and contradiction among taxonomists and pathologists (Cannon and Kirk 2000; Wingfield et al. 2012). Hence, the 18th International Botanical Congress, in Melbourne, Australia in 2011 (Hawksworth 2012) governed that the separate nomenclatural system will not be accepted from 30 July 2011 (Hawksworth 2012; Wingfield et al. 2012). The international Commission of Taxonomy of Fungi (ICTF) appointed different working groups to prepare lists for adopting names for pleomorphic genera. With the involvement of well-known taxonomists and pathologists, adopted lists were discussed at the 10th International Mycological Congress (Redhead 2014) and published in various journals (Johnston et al. 2014; Stadler et al. 2014; Wijayawardene et al. 2014d). Future usage of several pleomorphic fungi with coelomycetous asexual morphs have been discussed in Johnston et al. (2014), Stadler et al. (2014) and Wijayawardene et al. (2014c) and Maharachchikumbura et al. (2015). Beside the mentioned publications, Crous et al. (2009b), Barber et al. (2011), Minnis et al. (2012), Quaedvlieg et al. (2013), Ariyawansa et al. (2014b), Hongsanan et al. (2014), Voglmayr and Jaklitsch (2014), and Senanayake et al. (2015) also discussed pleomorphic genera. Table 8 summarizes future adoptions in nomenclature of pleomorphic genera with coelomycetous asexual morphs. Botryosphaeria-Dichomera-Neofusicoccum The taxonomic background of Botryosphaeria has been discussed in recent studies by Liu et al. (2012) and Phillips et al. (2013). Briefly, the original concept of the genus by Cesati and De Notaris (1863) was expanded over the years to encompass a broad range of morphologies. For example, Denman et al. (2000) mentioned that approximately 18 asexual genera have been linked with Botryosphaeria sensu lato. Among these, Diplodia, Dothiorella, Fusicoccum, Lasiodiplodia, Macrophoma and Sphaeropsis have been the subject of detailed taxonomic studies (Sivanesan 1984, Denman et al. 2000; Barber et al. 2005; Phillips et al. 2008, 2013; Liu et al. 2012). In view of the wide range of morphologies associated with Botryosphaeria sensu lato, Crous et al. (2006a) re-evaluated the genus and showed that it consists of 10 phylogenetic lineages, representing 10 distinct genera. As a result, Crous et al. (2006a), Phillips et al. (2008, 2013), Liu et al. (2012) and Slippers et al. (2013) recognized Botryosphaeria as a relatively small, monophyletic genus in the Botryosphaeriaceae with Fusicoccum asexual morphs. Since Botryosphaeria is the more commonly used name and is the type genus of the Botryosphaeriaceae, the older asexual typified name was treated as a synonym of the sexual typified name (Phillips et al. 2013; Wijayawardene et al. 2014d). Seven species were accepted by Phillips et al. (2013) who mentioned that six species are reported with asexual morphs or only as asexual morph. Crous et al. (2006a) introduced Neofusicoccum, which morphologically resembles Fusicoccum, but is phylogenetically distinct. Barber et al. (2005) described a dichomera-like asexual morph associated with some species of Neofusicoccum (which they reported as Fusicoccum), while Phillips et al. (2005, 2013) revealed that some isolates of Botryosphaeria dothidea also form a similar synasexual morph. Hence, it is not possible to differentiate Botryosphaeria (including Fusicoccum species) from Neofusicoccum based on dichomera-like synasexual morphs. In our phylogenetic analyses of combined ITS and EF sequence data, dichomera-like taxa cluster in Botryosphaeria and Neofusicoccum (Fig. 13). An isolate of the type species of Dichomera, D. saubinetii, (Fig. 281) resides in Fusicoccum, but this strain (CBS 990.70) was not derived from the type. Therefore we decline to treat Dichomera as a synonym of Botryosphaeria, but stress that it is important to epitypify the type species of Dichomera and designate an ex-epitype strain. Orphan genera, re-collecting and epitypification Approximately, 700 of coelomycetous taxa can be treated as orphan genera that are not placed in any taxonomic level Fungal Diversity (Wijayawardene et al. 2012b). However, it is important to place these orphan genera in a natural classification system. Hence, taxonomists rely on sequence data to understand the taxonomic positions and sexual-asexual relationships. Most of the coelomycetous genera lack cultures and sequence data is unavailable or some genera lack molecular data of the type species. It is essential to re-collect and epitypify species of particular genera (Ariyawansa et al. 2014a). Moreover, culture based studies and phylogenetic studies must be carried out to establish clear generic boundaries, taxonomic placements and sexual-asexual relationships. Fungus-Host Index for dematiaceous coelomycetes In this section, we summarize the host-fungi relationships based on Sutton (1980), Nag Raj (1993), Ellis and Ellis (1985, 1997), Farr and Rossman (2016) and other recent publications. However, we list host of type species and other species belong to sensu stricto of the respective genus when there are more than ten epithets in Index Fungorum (2016). Genera occur on more than ten host species are indicated by asterix and referred to USDA. Alanphillipsia Aloe sp. Euphorbia sp. Amarenographium Ammophila arenaria Uniola paniculata Palm sp.
