Hyde Received: 19 August 2014 / Accepted: 11 September 2014 / Published online: 7 October 2014 # School of Science 2014 Abstract Phaeosphaeriaceae is a large and important family in the order Pleosporales which includes economically important plant pathogens. Species may also be endophytes or saprobes on plant hosts, especially on monocotyledons (e.g., Cannaceae, Cyperaceae, Juncaceae, Poaceae); some species have also been reported on dicotyledons. The family previously accommodated 35 sexual and asexual genera and comprised more than 300 species with a range of morphological characters. The morphological characters of taxa in this family are often ambiguous and can be confused with other taxa in Leptosphaeriaceae and Montagnulaceae. Fourteen specimens of the type genera of Phaeosphaeriaceae were loaned from herbaria worldwide and were re-examined and illustrated. Fresh collections were obtained from Italy and Thailand, characterized, examined, isolated into pure culture and used to obtain molecular data. The asexual state was induced where possible on sterile bamboo pieces placed on water agar. Multigene phylogenetic analyses of ITS, LSU, SSU, RPB2 and TEF1 sequence datasets were carried out using maximum likelihood, maximum parsimony and Bayesian analysis. Molecular analyses shows that 21 genera (Amarenomyces, Ampelomyces, Chaetosphaeronema, Dematiopleospora, Entodesmium, Loratospora, Neosetophoma, Neostagonospora, Nodulosphaeria, Op hiobolus, Ophiosphaerella, Paraphoma, Parastagonospora, Phaeosphaeria, Phaeosphaeriopsis, Sclerostagonospora, Setomelanomma, Setophoma, Vrystaatia, Wojnowicia and Xenoseptoria) belong in Phaeosphaeriaceae, while seven Electronic supplementary material The online version of this article (doi:10.1007/s13225-014-0308-3) contains supplementary material, which is available to authorized users.

Amarenomyces is reinstated and Nodulosphaeria is confirmed in Phaeosphaeriaceae. Eudarluca is distinguished from Sphaerellopsis based on its morphological characters and is typical of Phaeosphaeriaceae. ITS gene phylogenetic analysis indicates tha t Sphaere llopsis be longs to Leptosphaeriaceae. Ophiobolus species form a clade within Phaeosphaeriaceae while Ophiosphaerella is shown to be polyphyletic. Phaeosphaeria sensu stricto is redefined. Two new species of Phaeosphaeria and one of Phaeosphaeriopsis are introduced while the asexual states of Phaeosphaeria chiangraina and Phaeosphaeriopsis dracaenicola are reported. Scolicosporium minkeviciusii forms a sister clade with Neostagonospora and Parastagonospora in Phaeosphaeriaceae. However, Scolicosporium minkeviciusii is not the type species. Thus, the placement of Scolicosporium sensu stricto in Phaeosphaeriaceae is questionable. Phylogenetic analysis of combined ITS and LSU genes, confirm the placement of Septoriella oudemansii in Phaeosphaeriaceae. However, it is not represented by the generic type, thus the placement of Septoriella is questionable. Setophaeosphaeria is excluded from Phaeosphariaceae as the type species, Sp. hemerocallidis forms a clade at the base of Cucurbitariaceae. Wilmia clusters in Didymosphaeriaceae and is synonymized under Letendraea. Barria, Chaetoplea, Hadrospora, Lautitia, Metameris, Mixtura and Pleoseptum are excluded from Phaeosphaeriaceae based on their morphological characters. The asexual genera Mycopappus and Xenostigmina are excluded from this family based on the phylogenetic evidence; these genera form a clade close to Melanommataceae. Keywords Asexual state .

Taxonomy Introduction Phaeosphaeriaceae is a large and important family in Pleosporales and was previously reported to include more than 300 species in 35 genera (18 sexual and 17 asexual genera; Kirk et al. 2008; Zhang et al. 2009; Hyde et al. 2013; Wijayawardene et al. 2014b). Specie s of Phaeosphaeriaceae, especially the asexual taxa, are important plant pathogens, infecting major crops (Shoemaker and Babcock 1989b; Carson 2005; Stukenbrock et al. 2006; Zhang et al. 2009; Quaedvlieg et al. 2013; Hyde et al. 2014). For example, Parastagonospora nodorum (Berk.) Quaedvlieg et al. causes leaf and glume blotch of cereals crops, especially barley and wheat (Cunfer 2000; Fungal Diversity (2014) 68:159–238 Stukenbrock et al. 2006; Vergnes et al. 2006; Quaedvlieg et al. 2013) while Parastagonospora avenae causes leaf blotch of barley and rye (f.sp. tritici) (Cunfer 2000; Quaedvlieg et al. 2013). Furthermore, many genera have also been reported as pathogens causing leaf spots on various hosts, such as Neosetophoma, Phaeosphaeria, Phaeosphaeriopsis, Setophoma, Wojnowicia and Xenoseptoria (Cason 2005; Arzanlou and Crous 2006; Quaedvlieg et al. 2013; Wijayawardene et al. 2013b; Crous et al. 2014; Phookamsak et al. 2014). Some species are also endophytes (Wang et al. 2005; Sánchez Márquez et al. 2007; Lawrey et al. 2012), Lautitia danica (Berl.) S. Schatz is obligate parasite on algae (Schatz 1984; Barr 1987b; Zhang et al. 2012) and many species are saprobic on monocotyledons, especially poaceous hosts, while others may be saprobes on herbaceous dicotyledonous hosts (Shoemaker 1984; Shoemaker and Babcock 1989b; Schoch et al. 2006; Zhang et al. 2009, 2012; De Gruyter et al. 2010; Hyde et al. 2013; Quaedvlieg et al. 2013). History of Phaeosphaeriaceae Introduction to the family The family Phaeosphaeriaceae was introduced by Barr (1979) and typified by Phaeosphaeria with Ph. oryzae as the type species. The important family characters were described by Barr (1979) as “saprobic, pathogenic or hyperparasitic fungi typically on herbaceous stems or monocotyledonous leaves, culms, or flowers, but also on woody substrates. Ascomata were described as immersed, erumpent or superficial, globose or conical, short papillate, small to medium, asci as bitunicate, and ascospores as hyaline, yellowish or brown, narrowly or widely obovoid, aseptate or septate” Subsequent authors are in agreement with this description (Barr 1987b, 1992a, b; Zhang et al. 2012; Hyde et al. 2013). When Barr (1979) introduced the family Phaeosphaeriaceae, 15 genera were included (Table 1); i.e. Comoclathris, Didymella, Eudarluca, Heptameria, Leptosphaeria, Loculohypoxylon, Metameris, Microthelia, Nodulosphaeria, Ophiobolus, Paraphaeosphaeria, Phaeosphaeria, Rhopographus, Scirrhodothis and Teichospora (Barr 1979; Zhang et al. 2009, 2012). Arrangement of genera in Phaeosphaeriaceae based on morphology (1979–1999) Over the next 20 years the family was revised with additions and exclusions of genera and this is detailed below (Table 1). These revisions were based on morphological characters and were subjective with decisions made based on perceived importance of characters. During this period it was very difficult for researchers to develop higher classification Fungal Diversity (2014) 68:159–238 161 Table 1 Synopsis of Phaeosphaeriaceae from 1979 to 2014 Barr (1979) Barr (1992a) Comoclathris Didymella Eudarluca Heptameria Leptosphaeria Loculohypoxylon Metameris Microthelia Nodulosphaeria Ophiobolus Paraphaeosphaeria Phaeosphaeria Rhopographus Scirrhodothis Teichospora Bricookea Chaetoplea Didymella Graphyllium Hadrospora Kalmusia Lautitia Metameris Montagnula Nodulosphaeria Ophiosphaerella Paraphaeosphaeria Phaeosphaeria Rhopographus Lumbsch and Huhndorf (2010) Barria Bricookea Carinispora Chaetoplea Entodesmium Eudarluca Hadrospora Isthmosporella Lautitia Metameris Mixtura Nodulosphaeria Ocala Ophiobolus Ophiosphaerella Phaeosphaeria = Amarenomyces Phaeosphaeriopsis Pleoseptum Setomelanomma Wilmia Hyde et al.

(2014b) and in this study researchers did their work to the best of their ability and have often been proven correct. 162 Barr (1982) included the monotypic genus Bricookea in Phaeosphaeriaceae, while Schatz (1984) introduced Lautitia, a parasite on red algae, and accommodated it in the family. Barr (1987a) transferred Leptosphaeria as the type to establish the new family Leptosphaeriaceae, because of its large scleroplectenchymatous, thick-walled peridium cells and host preference on dicotyledons (Barr 1987a, b; Khashnobish and Shearer 1996; Câmara et al. 2002). Barr (1987b) also transferred Ophiobolus and Heptameria to Leptosphaeriaceae and followed by Tanaka and Harada (2005). Eudarluca, Loculohypoxylon and Teichospora were placed in Dacampiaceae, while some species of Microthelia were regarded as synonyms of Kirschsteiniothelia, and subsequently placed in Pleosporaceae (Hawksworth 1985; Barr 1987b). Montagnula was considered as a part of Pleospora (Barr 1987b), however, the genus was re-established by Crivelli (1983). Barr (1987b) added Bricookea, Chaetoplea, Kalmusia, Lautitia and Ophiosphaerella and suggested that Amarenomyces and Entodesmium could also be accommodated in Phaeosphaeriaceae. Boise (1989) introduced Hadrospora as a new genus in Phaeosphaeriaceae and additionally, Sulcispora was established in Phaeosphaeriaceae by Shoemaker and Babcock (1989b). More recently, Mixtura (Syd.) Eriksson and Yue (1990) was placed, with some uncertainty in Phaeosphaeriaceae. Eriksson and Hawksworth (1991) included Entodesmium and Peridiothelia in the family but this was disputed by Barr (1992a). It was suggested that Entodesmium should be placed in Lophiostomataceae because of its abrupt, beak-like apex and the periphysate ostioles which were illustrated by Shoemaker (1984) and Peridiothelia could be accommodated in Pleomassariaceae. Thus, Barr (1992a) accepted only 14 genera in Phaeosphaeriaceae: Bricookea, Chaetoplea, Didymella, Graphyllium, Hadrospora, Kalmusia, Lautitia, Metameris, Montagnula, Nodulosphaeria, Ophiosphaerella, Phaeosphaeria, Paraphaeosphaeria and Rhopographus (Table 1). Shoemaker and Babcock (1992) revised the taxonomy of the Pleosporales and transferred Comoclathris to Diademaceae and Graphyllium was moved to Hysteriaceae based on its hysterothecia with a slit-like opening (Zhang et al. 2011; Ariyawansa et al. 2014a). The marine fungus, Carinispora K.D. Hyde (Hyde 1992), a saprobe on the intertidal Nypa palm was placed in Phaeosphaeriaceae, and it was noted that the genus was closely related to Phaeosphaeria, although differed in several important aspects. The genus was tentatively placed in Phaeosphaeriaceae due to lack of molecular data (Hyde 1992, 1994; Jones et al. 2009; Lumbsch and Huhndorf 2007, 2010). Eriksson and Hawksworth (1993) listed 13 genera in Phaeosphaeriaceae: Bricookea, Carinispora, Eudarluca, H ad ro s p or a , L a u t i t i a, M et am e ri s, M i x t u r a, Nodulosphaeria, Ophiosphaerella, Paraphaeosphaeria, Fungal Diversity (2014) 68:159–238 Phaeosphaeria, Sulcispora and Teratosphaeria (Table 1). Scirrhodothis was synonymised under Metameris, while Didymella was excluded from the family. Sivanesan (1984) proposed placing Didymella in Pleosporaceae, while Reddy et al. (1998) treated it in Venturiaceae (Dianese et al. 2001; Zhang et al. 2012). Yuan (1994) established Barria as a monotypic genus from Picea within Phaeosphaeriaceae. The peridium in this genus is composed of thin-walled pseudoparenchymatous cells and it has narrow cellular pseudoparaphyses. Ramaley and Barr (1995) introduced the monotypic genus Pleoseptum from Yucca baccata and reported Camarosporium yuccaesedum Fairm. as the asexual state of the genus. Pleoseptum shares morphological characters with several Dothideomycetes genera (Ramaley and Barr 1995). However there is a lack of molecular phylogenetic evidence to place this genus in Phaeosphaeriaceae (Zhang et al. 2012; Hyde et al. 2013). Wilmia, a monotypic genus, was introduced as a pathogen of Memora pedunculata and formed asexual morphs associated with the sexual morph. The morphology is similar to several genera such as Barria, Lautitia, and Metameris in the Phaeosphaeriaceae (Dianese et al. 2001; Zhang et al. 2012; Ariyawansa et al. 2014b). Dothideopsella was characterized by broadly pseudoparenchymatous cells, and phragmosporous, brown ascospores. The genus was introduced by von Höhnel (1915) to accommodate non-congeneric species of Leptosphaeria (Barr and Rogerson 1999). However, the genus was reinstated under Leptosphaeria by von Arx and Müller (1975) and this was followed in Kirk et al. (2001, 2008). Barr and Rogerson (1999) treated Dothideopsella in Botryosphaeriaceae, while Lumbsch and Huhndorf (2010) placed the genus in Dothideomycetes, genera incertae sedis. Recently, Dothideopsella was reported as a genus in Leptosphaeriaceae which contained four epithet species. However, Ariyawansa et al. (2013) observed the type species and found that the genus was typical in Phaeosphaeriaceae rather than Leptosphaeriaceae. Thus the genus was transferred to Phaeosphaeriaceae and is followed by Wijayawardene et al. (2014b). Various other genera included in Phaeosphaeriaceae by Barr (1979, 1987a, b, 1990a, 1992a), have been transferred to other families based on morphology. Comoclathris is currently accommodated in the Diademaceae (Shoemaker and Babcock 1992; Zhang et al. 2012; Hyde et al. 2013; Ariyawansa et al. 2014a), Heptameria and Rhopographus are treated in Dothideomycetes, genera incertae sedis (Lumbsch and Huhndorf 2007, 2010; Zhang et al. 2012; Hyde et al. 2013), Loculohypoxylon and Teichospora in the family Teichosporaceae (Barr 2002; Lumbsch and Huhndorf 2007, 2010; Zhang et al. 2012; Hyde et al. 2013; Wijayawardene et al. 2014b). Fungal Diversity (2014) 68:159–238 Initial phylogenetics for resolving Phaeosphaeriaceae In 1995 the first phylogenetic evidence for placement of genera in Phaeosphaeriaceae started to emerge. Morales et al. (1995) attempted to determine the relationships between Leptosphaeria and Phaeosphaeria species using rRNA gene sequences. The separation of Leptosphaeria and Phaeosphaeria was not strongly supported and the asexual states were phylogenetically uninformative in their analysis. Phylogenetic analysis indicated that Phaeosphaeria was part of Leptosphaeriaceae due to the fact that Ph. nodorum and Ph. microscopica formed a clade close to L. doliolum, the type species of Leptosphaeria (Morales et al. 1995; Câmara et al. 2002.). Khashnobish and Shearer (1996) found that Phaeosphaeria formed a distinct group separate from L e p t o s ph a e r i a b a s e d o n a c l a d i s t i c a n a l y s i s o f morphological and sequence data. Câmara et al. (2002) concluded that peridial characters, asexual state and host preferences are taxonomically and phylogenetically significant at the generic level, with Leptosphaeria sensu stricto and Phaeosphaeria sharing a more recent common ancestor in their analysis. Kruys et al. (2006) investigated the relationships of families in Pleosporales and observed that Phaeosphaeriaceae is closely related to Leptosphaeriaceae and formed an unresolved monophyletic group. The main features distinguishing the two families are the ascomata wall characters. In Leptosphaeriaceae taxa have scleroplectenchymatous ascomata walls and in Phaeosphaeriaceae taxa have thinwalled, pseudoparenchymatous ascomata walls (Câmara et al. 2002; Cheng et al. 2004; Schoch et al. 2006). Shiraia, an uncertain genus grouped with Leptosphaeriaceae and Phaeosphaeriaceae in the phylogenetic analysis of Kruys et al. (2006). Cheng et al. (2004) suggested that Shiraia should be treated as a member of Phaeosphaeriaceae. The genus was unofficially placed in Shiraiaceae, by Ogawa et al. (2003) (see GenBank AB105798), but was not validly published (Kruys et al. 2006; Liu et al. 2013). Liu et al. (2013) illustrated and epitypified the type species, Shiraia bambusicola from fresh collection in Zhejiang Province, China. Based on their phylogenetic investigation, Shiraia formed a distinct clade separate from Phaeosphaeriaceae. Therefore, Liu et al. (2013) introduced a new valid family Shiraiaceae to accommodate a monotypic genus Shiraia in Pleosporales and illustrated a coelomycetous asexual state. Zhang et al. (2009) incorporated multigene phylogenetic analysis and included 15 families in Pleosporales. They included four families in the suborder Pleosporineae viz. Didymellaceae, Leptosphaeriaceae, Phaeosphaeriaceae and Pleosporaceae. In addition, they introduced two new families, Amniculicolaceae and Lentitheciaceae to accommodate some freshwater fungi (Zhang et al. 2009, 2012). Zhang et al. (2009) re-accommodated Ophiobolus in Phaeosphaeriaceae due to 163 its morphological characters and because Ophiobolus is often associated with the asexual genus Chaetosphaeronema on the host (Petrak 1944). However, this link has not been confirmed (Zhang et al. 2009). Zhang et al. (2012) re-circumscribed the families Phaeosphaeriaceae in Pleosporales. These authors treated 18 sexual genera base on morphology in Phaeosphaeriaceae and accepted Entodesmium, Ophiosphaerella, Phaeosphaeria and Setomelanomma based on phylogenetic analysis (Table 1). The freshwater genera Isthmosporella Shearer and Crane (1999) and Ocala Raja et al. (2009) were also accommodated in Phaeosphaeriaceae. Zhang et al. (2012), however, removed these genera from Phaeosphaeriaceae based on morphological characters and phylogenetic analysis; Ocala formed a unique clade basal to Jahnulales (Shearer et al. 2009) and Isthmosporella was treated in Pleosporales, genera incertae sedis. Hyde et al. (2013) listed 27 sexual and asexual genera in Phaeosphaeriaceae and later, Wanasinghe et al. (2014) introduced the monotypic genus, Dematiopleospora typified by D. mariae in Phaeosphaeriaceae based on molecular data. Furthermore, Crous et al. (2014) included Setophaeosphaeria Crous & Y. Zhang ter with Sp. badalingensis Crous & Y. Zhang ter, Sp. hemerocallidis Crous & Y. Zhang ter and Sp. setosa (Leuchtm.) Crous in Phaeosphaeriaceae. Setophaeosphaeria is morphologically and phylogenetically distinct from Phaeosphaeria oryzae, the type species of Phaeosphaeriaceae, but is similar to Ph. setosa. Thus the genus was established to accommodate phaeosphaeria-like species. Recent molecular studies place Kirschsteiniothelia in a new family Kirschsteiniotheliaceae based on molecular data (Boonmee et al. 2012) and Microthelia species are treated in synonymy of various genera of Dothideomycetes (Hyde et al. 2013). Kalmusia, Montagnula and Paraphaeosphaeria are accommodated in Montagnulaceae (Boonmee et al. 2012; Hyde et al. 2013; Lumbsch and Huhndorf 2010; Zhang et al. 2009, 2012; Ariyawansa et al. 2014b). Several genera in Phaeosphaeriaceae, such as Barria, Bricookea, Chaetoplea, Eudarluca, Hadrospora, Lautitia, Metameris, Mixtura, Nodulosphaeria, Ophiobolus, Pleoseptum, and Wilmia lack molecular data. History of genera Amarenomyces Eriksson was introduced as a new genus based on its multi-layered endotunica and large, thick-walled and sheathed ascospores (Eriksson 1981). Eriksson (1982) reported Amarenographium to be the asexual state of Amarenomyces. Amarenomyces was synonymized under Phaeosphaeria by Zhang et al. (2009) based on phylogenetic evidence from Amarenomyces ammophilae (Lasch) O.E. Erikss. which formed a related clade with other Phaeosphaeria species. 164 Didymella was treated as a member of Phaeosphaeriaceae by Barr (1979) when she introduced the new family Phaeosphaeriaceae. However, Silva-Hanlin and Hanlin (1999) suggested that Didymella belongs in Pleosporaceae rather than Phaeosphaeriaceae based on phylogenetic relationships, while Lumbsch and Huhndorf (2007) treated Didymella in Pleosporales, genera incertae sedis. Later, De Gruyter et al. (2009) introduced a new family Didymellaceae based on a multigene phylogenetic analysis with Didymella as the type genus. Entodesmium was introduced by Reiss (1854) as typified by E. rude Riess associated with legumes (Zhang et al. 2009). The genus was previously placed in Lophiostomataceae based on its periphysate papilla (Eriksson and Hawksworth 1990; Barr 1992b; Zhang et al. 2009). Liew et al. (2000) sequenced a strain of E. rude and their phylogenetic analysis indicated that Entodesmium belongs to Phaeosphariaceae which has been upheld by subsequent authors (Schoch et al. 2009; Zhang et al. 2009, 2012; Hyde et al. 2013, 2014). However, there is only one putative strain of Entodesmium rude (CBS 650.86) available in GenBank (Liew et al. 2000), and this is not apparently linked to any herbarium material. Eudarluca was introduced by Spegazzini (1908) as a hyperparasite in the uredinia of rust fungi from Canna (Zhang et al. 2012). Sphaerellopsis was reported to be the asexual state of this genus (Yuan et al. 1998; Nischwitz et al. 2005; Zhang et al. 2012). Many strains of Eudarluca caricis (Fr.) O.E. Erikss. are available in GenBank. Nischwitz et al. (2005) investigated host specialization and relationships of Eudarluca caricis with Ampelomyces. Based on the phylogenetic analysis, their results have shown that Eudarluca caricis formed a clade with other pleosporalean taxa and appeared to be host-specific (Nischwitz et al. 2005). The phylogenetic investigation was limited to variation between differentiated isolates and could not resolve the current placement of Eudarluca in Phaeosphaeriaceae (Bayon et al. 2006; Zhang et al. 2012). Katumotoa was introduced as a monotypic genus in Phaeosphaeriaceae and was tentatively placed in Phaeosphaeriaceae (Tanaka and Harada 2005). Later, Ta n a k a e t a l . ( 2 0 0 9 ) re m o v e d K a t u m o t o a f r o m Phaeosphaeriaceae and accommodated this genus in the family Lentitheciaceae (Zhang et al. 2009), based on morphological and phylogenetic evidence. Loratospora was introduced by Kohlmeyer and Volkmann-Kohlmeyer (1993) as a monotypic genus. The type species, Loratospora aestuarii Kohlm. & Volkm.-Kohlm. is an obligate and facultative marine taxon (Kohlmeyer and Volkmann-Kohlmeyer 1993; Monkai et al. 2013). Suetrong et al. (2009) transferred Loratospora to Phaeosphaeriaceae based on phylogenetic data, whereas based on morphology it had previously been placed in Planistromellaceae (Barr 1996). Fungal Diversity (2014) 68:159–238 Ophiosphaerella was introduced by Spegazzini (1909) with Op. graminicola Speg. as the type species. Barr (1987b) placed Ophiosphaerella in Phaeosphaeriaceae, due to its morphological characters (Shoemaker and Babcock 1989b; Dong et al. 1998). The placement in Phaeosphaeriaceae was confirmed by Zhang et al. (2009, 2012) and Hyde et al. (2013) based on molecular phylogeny. Phaeosphaeriopsis was introduced to accommodate Paraphaeosphaeria species that were not congeneric based on morphological characters and phylogenetic investigation and that had a Phaeostagonospora asexual state (Câmara et al. 2003; Zhang et al. 2012). The placement of the genus in Phaeosphaeriaceae was confirmed by multi-gene analysis (Quaedvlieg et al. 2013; Thambugala et al. 2014). Setomelanomma was introduced by Morelet (1980) as a pathogen on blue and white spruce (Morelet 1980; Rossman et al. 2002). The genus was considered morphologically similar to Phaeosphaeriaceae (Rossman et al. 2002; Zhang et al. 2012). Rossman et al. (2002) confirmed the genus belongs in Phaeosphaeriaceae based on a phylogenetic analysis and this was verified with multi-gene analyses (Schoch et al. 2009; Zhang et al. 2009, 2012; De Gruyter et al. 2012; Hyde et al. 2013; Wijayawardene et al. 2014b). Placement of asexual genera in Phaeosphaeriaceae Before the era of molecular phylogeny it was difficult to establish if asexual genera belonged in Phaeosphaeriaceae unless single ascospore cultures produced the asexual morph or where the asexual morph was associated with the sexual state on the host (Eriksson 1982; Ramaley 1995; Ramaley and Barr 1995; Yuan et al. 1998; Câmara et al. 2003; Nischwitz et al. 2005). Previous to the compilation by Hyde et al. (2011) there were few attempts to incorporate asexual genera in sexually defined families. Perhaps the first report of an asexual state of Phaeosphaeriaceae is that of Eriksson (1982) who reported Amarenographium to be the asexual state of Amarenomyces. Barr (1987b) listed nine coelomycetous genera, Ascochyta, Chaetodiplodia, Coniothyrium, Microdiplodia, Microsphaeropsis, Phoma, Scolecosporiella, Stagonospora and Sphaerellopsis in Phaeosphaeriaceae based on their holoblastic or enteroblastic conidiogenesis and aseptate or septate conidia. Camarosporium yuccaesedum Fairm formed conidiomata on leaves of Yucca baccata that were associated with ascomata of Pleoseptum yuccaesedum, the type species of Pleoseptum, (Ramaley and Barr 1995; Zhang et al. 2012). Based on its structurally similar and close association, Ramaley and Barr (1995) linked Camarosporium yuccaesedum as an asexual state of Pleoseptum. Camarosporium species had been reported as asexual morphs in various genera of Botryosphaeriales and Cucurbitariaceae with doubtful polyphyletic support (Crous et al. 2006; Kirk Fungal Diversity (2014) 68:159–238 et al. 2008; Liu et al. 2012; Zhang et al. 2012; Doilom et al. 2013). However, Wijayawardene et al. (2014a, c, d) recognized Camarosporium sensu stricto as a distinct phylogenetic linage in Pleosporineae, Pleosporales hence introduced Camarosporiaceae, (Wijayawardene et al. 2014a, d) Hyde et al. (2011) and Wijayawardene et al. (2012) also listed Hendersonia as an asexual state of Phaeosphaeriaceae. However, the genus was synonymized under Stagonospora and is currently placed in Massarinaceae (Swart and Walker 1988; Quaedvlieg et al. 2013). Parahendersonia Ramaley (1995) was classified by its ampulliform conidiogenous cells producing thick-walled, brown, (1–)3-septate conidia. This monotypic genus is represented by P. dasylirionis. The sexual state was reported as Chaetoplea dasylirionis on Dasylirion (Agavaceae) in Leptosphaeriaceae (Ramaley 1995; Calatayud and Etayo 2001). However, Barr (1987b) accommodated Chaetoplea in Phaeosphaeriaceae and reported a microdiplodia-like asexual state for Chaetoplea (Barr 1990b; Zhang et al. 2012). Recently, Parahendersonia was treated in Leptosphaeriaceae (Index Fungorum 2014). Rhabdospora was originally established to accommodate septoria-like species associated with stems of Nerium oleander L. (Priest 2006; Quaedvlieg et al. 2013). The genus was treated in the taxonomic studies of Sutton (1980) which 11 Rhabdospora species currently classified under Septoria in Mycosphaerellaceae (Quaedvlieg et al. 2013). Hyde et al. (2011) listed Rhabdospora as the asexual state of Phaeosphaeriaceae, while Zhang et al. (2012) treated the genus as an asexual state of Ophiobolus. Wijayawardene et al. (2014b) treated the genus in Dothideomycetes, genera incertae sedis. There are 648 epithets listed in Index Fungorum (2014) for Rhabdospora and it was accommodated in Mycosphaerellaceae. However, Rhabdospora is a poorly understood genus and is in need of modern taxonomic and molecular treatment (Quaedvlieg et al. 2013). The type species of Scolecosporiella, Sc. typhae (Oudemans) Petr. was reported as the asexual state of Phaeosphaeria typharum (Desm.) L. Holm (Nag Raj 1989). The genus has been re-described taxonomic revision by Sutton (1968, 1980) and Nag Raj (1989). Various sexual genera, such as Ophiobolus, Ophiosphaerella, and Phaeosphaeria have been reported as Scolecosporiella sexual states (Farr et al. 1989; Nag Raj 1989; Shoemaker and Babcock 1989b; Hyde et al. 2011; Zhang et al. 2012). Tiarospora was reported as an asexual member of Phaeosphaeriaceae by Kirk et al. (2008). However, there are no molecular data to prove that this genus belongs in Phaeosphaeriaceae. Tiarospora has four epithets in Index Fungorum (2014) with T. perforans (Sacc.) Höhn being listed as a synonym of Montagnula perforans (Aptroot 2006). 165 Molecular data has allowed linkage of asexual genera in Phaeosphaeriaceae A s c o c h y t a , C h a e t o d i p l o d i a , M i c ro d i p l o d i a a n d Microsphaeropsis have been reported as asexual states of Phaeosphaeriaceae (Barr 1987b); however, using phylogenetic evidence Crous et al. (2006) treated Microdiplodia as the asexual state of Karstenula in Montagnulaceae (Ariyawansa et al. 2014b). Liu et al. (2012) and Hyde et al. (2013) reported Microdiplodia as an asexual state in Botryosphaeriaceae. Ascochyta and Microsphaeropsis were treated in Didymellaceae based on phylogenetic evidence with the sexual morph of these genera described as Didymella (De Gruyter et al. 2009; Aveskamp et al. 2010). Ascochyta was shown to be polyphyletic in Pleosporales by subsequent researchers (De Gruyter et al. 2009, 2012; Aveskamp et al. 2010). Furthermore, allied Ascochyta species were determined to belong in Pleosporaceae by De Gruyter et al. (2012). A Chaetodiplodia strain formed a clade within Leptosphaeriaceae; however, the genus is polyphyletic in Pleosporaceae (De Gruyter et al. 2009, 2012). Based on phylogenetic evidence, Câmara et al. (2003) introduced the new genus Phaeosphaeriopsis in Phaeosphaeriaceae and transferred Paraphaeosphaeria n o l i n a e A . W. R a m a l e y t o P h a e o s p h a e r i o p s i s . Phaeostagonospora was reported as the asexual state based on its morphology (Ramaley 1997). Sexual and asexual morph connections were studied by Quaedvlieg et al. (2013) and Thambugala et al. (2014). De Gruyter et al. (2009) included Wojnowicia hirta (J. Schröt.) Sacc., the type species in their phylogenetic analysis and concluded that Wojnowicia hirta has an asexual state in Phaeosphaeriaceae and this phylogenetic placement was supported by Wijayawardene et al. (2013b, 2014b). Zhang et al. (2009) listed Ampelomyces, Chaetosphaeronema, Coniothyrium, Phoma, Plenodomus, Stagonospora and Wojnowicia (asexual genera) in Phaeosphaeriaceae. Based on phylogenetic evidence, Chaetosphaeronema was placed in Phaeosphaeriaceae and often formed a sister clade with the sexual genus Entodesmium (Zhang et al. 2009, 2012; Hyde et al. 2013; Wijayawardene et al. 2014b). Phoma radicina (McAlpine) Boerema, the type species of Phoma section Paraphoma formed a sister clade with the sexual genus Setomelanomma holmii M. Morelet as basal Phaeosphaeriaceae (Zhang et al. 2009, 2012; Hyde et al. 2013; Wijayawardene et al. 2014b). De Gruyter et al. (2010) introduced two new genera, Neosetophoma and Setophoma in Phaeosphaeriaceae and also re-introduced Paraphoma in Phaeosphaeriaceae based on phylogenetic evidence. Four Phoma species from Av e s k a m p e t a l . ( 2 0 1 0 ) w h i c h c l u s t e r e d i n Phaeosphaeriaceae were accommodated in these genera (De Gruyter et al. 2010). Hyde et al. (2011) reported 17 asexual 166 g e n e r a i n P h a e o s p h a e r i a c e a e ( Ta b l e 1 ) . L a t e r, Wijayawardene et al. (2012) updated the checklist of asexual states of Phaeosphaeriaceae and included the hyphomyceteous genera Harpophora and Mauginiella. In their compilation of families in Pleosporales, Zhang et al. (2012) accepted 17 asexual genera in Phaeosphaeriaceae. They excluded the hyphomycetous genera, based on a broad familial concept and phylogenetic support. Hyde et al. (2013) excluded Amarenographium which formed a clade outside Phaeosphaeriaceae and this is supported by Hodhod et al. (2012). Wijayawardene et al. (2013a) accommodated Scolicosporium minkeviciusii Treigienė in Phaeosphaeriaceae as this species formed a clade with other well-established asexual genera. Furthermore, Crous et al. (2013) revealed that Xenostigmina and Mycopappus grouped in Phaeosphaeriaceae in their phylogenetic analysis. Quaedvlieg et al. (2013) re-circumscribed the pathogenic fungi genera Septoria, and Stagonospora and related genera such as Phaeosphaeria and Phaeoseptoria. Based on their phylogenetic study, they introduced 14 new genera, 36 new species, and 19 new combinations. The new genera Neostagonospora, Parastagonospora, Xenoseptoria and Vrystaatia were placed in Phaeosphaeriaceae. Furthermore, they epitypified Phaeosphaeria oryzae I. Miyake and Phaeoseptoria papayae Speg. and confirmed sexual asexual connections. Phaeoseptoria was confirmed as the asexual morph of Phaeosphaeria based on the sequenced strain of P. papayae which formed a well-supported clade with Ph. oryzae. Crous et al. (2014) included Septoriella oudemansii Oudem. in Phaeosphaeriaceae. Septoriella was compared with species of Phaeosphaeriaceae and a megablast search of NCBI showed that Septoriella is similar to Phaeosphaeria caricis, Ph. ammophilae and Ophiosphaerella herpotricha with high percentage similarities (Crous et al. 2014). In a new outline of the Dothideomycetes, Wijayawardene et al. (2014b) proposed synonymies and suggested names for 34 genera while incorporating asexual genera into a natural classification. This publication resulted from the new ruling in article 59.1 of International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code) that a species or genus can only have one name. They listed 29 genera (17 only known as asexual genera) in Phaeosphaeriaceae. According to phylogenetic evidence, Ampelomyces species grouped in Didymellaceae and Phaeosphaeriaceae (De Gruyter et al. 2009; Aveskamp et al. 2010; Hyde et al. 2013; Wijayawardene et al. 2013a, 2014b). The type species of Ampelomyces, A. quisqualis Ces. formed a clade within Phaeosphaeriaceae (De Gruyter et al. 2009; Aveskamp et al. 2010; Wijayawardene et al. 2013a), while A. quercinus (Syd.) Rudakov grouped in Didymellaceae (De Gruyter et al. 2009). Therefore, Aveskamp et al. (2010) transferred all Fungal Diversity (2014) 68:159–238 Ampelomyces species belonging in Didymellaceae, to Phoma based on phylogenetic relationships. Coniothyrium Corda (1840) is characterized by pycnidial c on i d i o m at a, r ed u ce d c on i d i op h or es , a nn e l l i di c conidiogenous cells, with brown, aseptate or septate, verrucose conidia (De Gruyter et al. 2012). Based on the phylogenetic analyses, Coniothyrium was revealed as polyphyletic in Pleosporales (Verkley et al. 2004, 2014). The type species of Co niothyrium , C. palmarum Corda clustered in Leptosphaeriaceae (De Gruyter et al. 2009). In De Gruyter et al. (2012), C. palmarum formed a distinct clade with other Phoma species in the reinstated Coniothyriaceae based on phylogenetic analysis. De Gruyter et al. (2012) indicated that Coniothyrium had convergent evolution with similar characters found in other families in Pleosporales such as Cucurbitariaceae, Didymellaceae, Phaeosphaeriaceae, Leptosphaeriaceae, Montagnulaceae and Sporormiaceae. However, Coniothyrium concentricum (Desm.) Sacc. is related to Phaeosphaeriaceae. A new genus should be designated to accommodate this coniothyrium-like species (Hyde et al. 2013). Harpophora was introduced by Gams (2000) to accommodate phialophora-like species characterized by fast-growing, thin colonies and sickle-shaped phialoconidia (Gams 2000; Saleh and Leslie 2004). The genus contains the asexual state of Gaeumannomyces and Magnaporthe in Magnaporthaceae (Gams 2000; Saleh and Leslie 2004; Kirk et al. 2008; Yuan et al. 2010). Based on a homologous test using ITS sequence data, Abdullah et al. (2005) indicated that Mauginiella scaettae Cavara was closely related to species of Phaeosphaeria which formed a clade with Phaeosphaeria associated with non-grass hosts. It was concluded that Mauginiella may represent the asexual state of Phaeosphaeria following the suggestion of Câmara et al. (2002). Câmara et al. (2002) mentioned that the morphological characters, asexual state and host preferences are important to clarify Phaeosphaeria species. It has been suggested that a great deal of convergent evolution had occurred in species of Leptosphaeria and Phaeosphaeria (Câmara et al. 2002; Abdullah et al. 2005). Phoma species have been described as the asexual state of various genera of Dothideomycetes i.e. Didymella, Mycosphaerella, Leptosphaeria and Pleospora (Boerema 1997; De Gruyter et al. 2009). De Gruyter et al. (2009) carried out a re-classification of the Phoma complex based on molecular phylogeny. Their results showed that Phoma was polyphyletic and was subsequently classified in nine sections: Phoma, Heterospora, Paraphoma, Peyronellaea, Phyllostictoides, Sclerophomella, Plenodomus, Macrospora, and Pilosa (Boerema 1997; Boerema et al. 2004; De Gruyter et al. 2009). Based on phylogenetic evidence, they concluded that Phoma section Paraphoma, as typified by Ph. radicina (McAlpine) Boerema can be assigned in Phaeosphaeriaceae, Fungal Diversity (2014) 68:159–238 while Ph. heteromorphospora, the type species of Phoma section Heterospora should be treated in Leptosphaeriaceae. Additionally, the family Didymellaceae was proposed to accommodate others Phoma sections viz. Macrospora, Peyronellaea, Phoma, Phyllostictoides and Sclerophomella (De Gruyter et al. 2009). Aveskamp et al. (2010) indicated that the current Boeremaean subdivision was incorrect as Phoma is polyphyletic comprising six distinct clades in Pleosporales and appeared to be common in different families (Aveskamp et al. 2010). Therefore, De Gruyter et al. (2012) concluded that Phoma should be restricted only to Didymellaceae, while other Phoma sections were transferred to related families. However, Lawrey et al. (2012) treated lichenicolous Phoma species in Phaeosphaeriaceae based on their multigene phylogenetic analysis. Therefore, a new genus should be introduced to accommodate all lichenicolous Phoma species in Phaeosphaeriaceae (Hyde et al. 2013). Plenodomus Preuss is typified by Pl. rabenhorstii Preuss to accommodate the phoma-like species which Boerema (1982) synonymized under Phoma section Plenodomus (Boerema et al. 2004; Torres et al. 2005). Torres et al. (2005) mentioned that Reddy et al. (1998) treated phoma-like species with the sexual state known as Leptosphaeria in Plenodomus in Leptosphaeriaceae and concluded that Phoma should be restricted to the species relating to Didymella in Phaeosphaeriaceae. Zhang et al. (2009) listed Plenodomus in Phaeosphaeriaceae; however based on phylogenetic evidence, De Gruyter et al. (2012) reinstated the genus Plenodomus to accommodate Phoma section Plenodomus within Leptosphaeriaceae. Sclerostagonospora was typified by S. heraclei (Sacc.) Höhn. (1917) and characterized with pycnidial conidiomata with holoblastic, determinate, discrete, ampulliform to irregular conidiogenous cells, and subcylindrical, 3-septate, pale brown, verruculose conidia (Sutton 1980; Quaedvlieg et al. 2013). Sclerostagonospora differs from Stagonospora in its pigmented conidia (Quaedvlieg et al. 2013). Crous and Palm (1999) reported Sclerostagonospora leucadendri Crous & M.E. Palm as the asexual state of Leptosphaeria leucadendri Crous & M.E. Palm which occurs on leaves of Leucadendron. Based on phylogenetic analysis, Sclerostagonospora opuntiae (Ellis & Everh.) Huhndorf (CBS 118224) formed a clade with Phaeosphaeria and Phaeosphaeriopsis (Crous et al. 2008). Thus, Kirk et al. (2008) treated Sclerostagonospora as an asexual state in the Pleosporales. In Quaedvlieg et al. (2013), multigene phylogenetic analysis has shown that Sclerostagonospora phragmiticola Quaedvlieg et al. (CBS 338.86) is related to Phaeosphaeriaceae. Stagonospora is characterized by holoblastic or annellidic conidiogenesis and produces phragmoconidia (Schoch et al. 2006; Quaedvlieg et al. 2013). The genus was reported as an asexual genus in Phaeosphaeriaceae, which often clusters with Phaeosphaeria and Phoma in phylogenetic analyses 167 (Cunfer and Ueng 1999; Câmara et al. 2002; Solomon et al. 2006; Zhang et al. 2009, 2012; Hyde et al. 2013). Stagonospora has often been confused with Septoria; however, the genus was clarified by Cunfer and Ueng (1999) and Solomon et al. (2006). Based on phylogenetic evidence, Stagonospora is more closely related to other genera in Pleosporales, while Septoria clustered in Mycosphaerellaceae, Capnodiales (Quaedvlieg et al. 2013). Quaedvlieg et al. (2013) re-collected the type species of Stagonospora, St. paludosa (Sacc. & Speg.) Sacc. and their phylogenetic analysis showed that this species formed a separate clade with other Stagonospora species which occurred on Poaceae (i.e. St. avenae (A.B.. Frank) Bissett and St. nodorum (Berk.) E. Castell. & Germano). Therefore, Quaedvlieg et al. (2013) concluded that stagonospora-like species belonged in different genera and introduced the new genera, Neostagonospora and Parastagonospora to accommodate the stagonospora-like species in Phaeosphaeriaceae. The type species of Stagonospora, St. paludosa and other Stagonospora species grouped in Massarinaceae (Quaedvlieg et al. 2013). The aim of this study is to revisit all genera of Phaeosphaeriaceae and provide revised descriptions of the sexual and asexual morphs of the genera. Available generic type specimens were examined, described and illustrated. We have also collected fresh specimens from Thailand and Italy. Phylogenetic investigation of available sequence data reveals the current placement of genera in Phaeosphaeriaceae. Material and methods Herbarium examination, fungal isolation, morphology and asexual state study Type specimens of each genus in Phaeosphaeriaceae were obtained from BPI, BR, NY, S, and UB herbaria. Morphology of generic types were examined and re-described. Generic descriptions were provided based on the original descriptions and non type herbarium specimens if generic type specimens could not be located or loaned. Some types were redrawn from iconotype. Ascomata on herbarium material were rehydrated by adding 5 % KOH. Free hand sections and squash mounts were prepared and morphological characters were observed under stereo microscope and compound microscope. Collections of Phaeosphaeriaceae were made from Italy and Thailand and returned to the laboratory for examination. If the specimens were dry, they were incubated in a moist chamber for 2–3 days at 25 °C. Ascomata were sectioned by hand and examined under an Olympus SZH10 stereomicroscope. Macro-morphological characters were photographed using a Sony DSC-T110 digital camera. The micro- 168 morphological characters were captured by a Cannon 550D digital camera, using a Nikon ECLIPSE 80i compound microscope with DIC objectives. Indian ink was added to show mucilaginous sheaths surrounding ascospores. Cotton blue and congo red reagents were used as stains for checking ascospore septation and internal elements of the hamathecium. Permanent slides were prepared by mounting material on lactoglycerol and sealing with clear nail polish. Measurements were obtained using a Tarosoft (R) Image Frame Work version 0.9.7. Photographic plates were prepared in Adobe Photoshop version CS3 (Adobe Systems Inc., The United States). Pure cultures were obtained from single spores following the methods described in Chomnunti et al. (2014) and Phookamsak et al. (2013). Ascomata were cut at the apex and sides walls by a razor blade. The contents inside ascoma was picked and soaked in sterile water and broken up further mechanically with the sterile needle until a spore suspension was obtained. The ascospore suspension was dropped on water agar (WA; 15.0 g/L sterile distilled water) and incubated at room temperature overnight. The germinating spores were transferred to malt extract agar (MEA; 33.6 g/L sterile distilled water, Difco malt extract) and cultivated in corn meal agar (CMA, 17 g/l sterile distilled water, Difco corn meal agar) and potato dextrose agar (PDA; 39 g/L distilled water, Difco potato dextrose) for recording growth rates and culture characters. Sterile bamboo pieces on water agar (WA; 15 g/l sterile distilled water) were used to encourage production of asexual morphs. Cultures are deposited in Mae Fah Luang University Culture Collection (MFLUCC), and duplicated in the International Collection of Microorganisms from Plants (ICMP), Landcare Research, New Zealand. Herbarium specimens were prepared by drying the specimens with silica gel at room temperature for 7–10 days depending on the humidity and kept in envelopes or small boxes. The herbarium specimens are deposited in the herbarium of Mae Fah Luang University (MFLU), Chiang Rai, Thailand and duplicates in the New Zealand Fungal Herbarium (PDD), Landcare Research, New Zealand or Université Catholique de Louvain, Belgium (MUCL). Molecular and phylogenetic analysis Fungal DNA extraction, PCR amplification and sequencing The fungal colonies were grown on MEA/PDA at 25– 30 °C for 2–4 weeks. After 4 weeks, the fungal mycelium was scraped and transferred to micro centrifuge tube. The fungal genomic DNA was extracted by Biospin Fungus Genomic DNA Extraction Kit (BioFlux®, China) following the manufacturer’s instructions (Hangzhou, P.R. China). Fungal Diversity (2014) 68:159–238 DNA amplifications were performed by Polymerase Chain Reaction (PCR). The internal transcribed spacer (ITS) was amplified by using primers ITS4 and ITS5 as defined by White et al. (1990). The partial small subunit nuclear rDNA (SSU) was amplified by using primers NS1 and NS4 (White et al. 1990). The partial large subunit nuclear rDNA (LSU) was amplified by using primers LROR and LR5 (Vilgalys and Hester 1990). The partial RNA polymerase second largest subunit (RPB2) was amplified by using primers fRPB2-5F and fRPB2-7cR (Liu et al. 1999). The translation elongation factor 1-alpha gene (TEF1) was amplified by using primers EF1-983F and EF1-2218R (Rehner 2001). The amplification reaction were carried out following protocol: The final volume of the PCR reaction was 50μl which contained 2.0μl of DNA template, 1.5μl of each forward and reverse primers, 25μl of 2× Easy Taq PCR SuperMix (mixture of EasyTaqTM DNA Polymerase, dNTPs, and optimized buffer, Beijing TransGen Biotech Co., Ltd., Chaoyang District, Beijing, PR China) and 20μl sterilized water (Phookamsak et al. 2013). The PCR thermal cycle program of ITS, nuSSU, nuLSU and TEF1 genes amplification were provided as: initially 94 °C for 3 min, followed by 40 cycles of denaturation at 94 °C for 30 s, annealing at 55 °C for 50 s, elongation at 72 °C for 1 min, and final extension at 72 °C for 10 min. The PCR thermal cycle program for the partial RNA polymerase second largest subunit (RPB2) was obtained by step as initially 95 °C for 5 min, followed by 40 cycles of denaturation at 95 °C for 1 min, annealing at 52 °C for 2 min, elongation at 72 °C for 90 s, and final extension at 72 °C for 10 min. The quality of PCR products were checked on 1 % agarose gel electrophoresis strained with ethidium bromide. The PCR products were send for sequencing at Shanghai Sangon Biological Engineering Technology & Services Co., Ltd (Shanghai, P.R. China) (Phookamsak et al. 2013). Phylogenetic analyses Combined ITS, LSU, SSU, RPB2 and TEF1 sequence data were used for phylogenetic analysis in this study. The reference nucleotide sequences of Phaeosphaeriaceae and other selected families in Dothideomycetes were obtained from the GenBank database and included in the analysis (see Supplementary table). The fungal sequence strains were combined and aligned in MEGA6 (Tamura et al. 2013) and improved manually where necessary in BioEdit v. 7.2 (Hall 1999). The combined sequences alignment was analyzed by Bayesian, maximum likelihood and maximum parsimony methods. Bayesian analyses was carried out using MrBayes v. 3.0b4 (Ronquist and Huelsenbeck 2003). The best-fit model of sequences evolution was estimated by using MrModeltest 2.2 (Nylander 2004). Markov Chain Monte Carlo sampling (BMCMC) in MrBayes v. 3.0b4 (Huelsenbeck and Ronquist Fungal Diversity (2014) 68:159–238 2001) were used to determine the Posterior probabilities (PP) (Rannala and Yang 1996; Zhaxybayeva and Gogarten 2002). Phylogenetic trees were sampled every 100th generation (resulting in 10,000 total trees) in 1,000,000 generations from the running of six simultaneous Markov chains. The first 2,000 trees which contained the burn-in phase of the analyses were discarded. The remaining 8,000 trees were used to calculate the posterior probabilities (PP) in the majority rule consensus tree (Liu et al. 2011). A maximum likelihood analysis (ML) was performed in RaxmlGUI v.1.0 (Silvestro and Michalak 2011). Alignments in PHYLIP format were loaded and automatically checked their compatibility in raxmlGUI. The available substitution models consisting of a generalized time reversible (GTR) was applied with four rate classes and a discrete gamma distribution (Yang 1994) for nucleotides, symmetric, Markovian, and ordered models for morphological characters (Liu et al. 2011; Silvestro and Michalak 2011). The best scoring tree from a separate randomized tree under the same model was selected. Rapid bootstrap with nonparametric bootstrap iterations (Stamatakis et al. 2008) was run in 1,000 replicates with the GTR model and a discrete gamma distribution (Liu et al. 2011). A maximum parsimony (MP) analysis was conducted by using PAUP v. 4.0b10 (Swofford 2002). The heuristic search option with 1,000 random sequences addition and treebisection reconnection (TBR) of branch-swapping algorithm were performed. Maxtrees were setup at 1,000 and a zero of maximum branch length was collapsed. Gaps were treated as missing data and all characters were unordered and of equal weight. All multiple, equally parsimonious trees were saved. Descriptive tree statistics for parsimony consistency index (CI), retention index (RI), rescaled consistency index (RC) and homoplasy index (HI) was calculated. The robustness of the best parsimonious tree was estimated by a bootstrap (BT) value with 1,000 replicates, each with 10 replicates of random stepwise addition of taxa (Liu et al. 2011; Phookamsak et al. 2013). The best scoring phylogram from Bayesian analysis was selected for representing phylogenetic relationships and drawn in Treeview (Page 1996) with bootstrap values above and below the branches. All the sequences generated in this study have been deposited in GenBank (Liu et al. 2011; Phookamsak et al. 2013). Results and discussion Three phylogenetic reconstructions were generated to clarify the phylogenetic relationships of genera and species that have been accommodated in Phaeosphaeriaceae. Figure 1 deals with the genus and family level placement within the Phaeosphaeriaceae and Pleosporales. The dataset includes 169 LSU, SSU, RPB2, and TEF1 sequences and were analyzed using maximum likelihood (ML), maximum parsimony (MP) and Bayesian analyses. The dataset comprised 85 taxa, with Massaria inquinans (M 19) selected as the outgroup taxon. Twenty-nine Phaeosphaeriaceae taxa formed a wellsupported clade (74 % ML/ 1.00 PP) within the suborder Pleosporinae, while Mycopappus and Xenostigmina form a single clade close to Melanommataceae. Therefore, we exclude these later genera from Phaeosphaeriaceae in this study. Wilmia was synonymized under Letendraea by Ariyawansa et al. (2014b). Phylogenetic evidence shows Letendraea cordylinicola is related with Didymosphaeriaceae which form a strongly-supported clade (75 % ML/ 1.00 PP) with Paraphaeosphaeria michotii (CBS 652.86), Deniquelata barringtoniae (MFLUCC 11-0422) and Kalmusia brevispora (KT 2313) in Didymosphaeriaceae. Thus, Letendraea is excluded from Phaeosphariaceae in this study and transferred to Didymosphaeriaceae. Phaeosphaeriopsis, Parastagonospora, Ophiosphaerella, Phaeosphaeria and Setophoma are well-resolved genera and formed distinct clades, while the other clades comprised groups of genera without clear combining features or comprising more than one genus (Fig. 2). Figure 2 focuses on the phylogenetic relationships of genera in Phaeosphaeriaceae. The multigene combined dataset (ITS, LSU, SSU and RPB2) were obtained from maximum likelihood (ML), maximum parsimony (MP) and Bayesian analysis. Didymella exigua (CBS 183.55) was selected as the outgroup taxon. The dataset consists of 58 taxa, with 57 taxa belonging to the Phaeosphaeriaceae. Eleven clades (A– K) can be recognized in Fig. 2. Clade A comprises the genera Chaetosphaeronema, Dermatiopleospora, Entodesmium, Loratospora. Nodulosphaeria and Ophiobolus. Dermatiopleospora, Entodesmium and Loratospora are represented by their ex-type strains and type species. This clade needs better populating with many more species from the respective genera as it is presently not well-resolved. Ophiobolus cirsii (MFLUCC 13-0218) formed a robust clade (99 % ML/ 97 % MP/ 1.00 PP) with the asexual genus Chaetosphaeronema, while O. erythrosporus (MFLU 122225) forms a weakly supported clade with Entodesmium rude. However, Ophiobolus is not represented by its type species and the strains used have not been morphologically clearly defined (see Ariyawansa et al. 2014c). Clade B represents the genus Phaeosphaeriopsis and is well resolved in Phaeosphaeriaceae (97 % ML/ 93 % MP/ 1.00 PP). It is represented by the type species Ps. glaucopunctata (ex-type strain), plus other strains and a new species Ps. dracaenicola is also introduced here (see details in “Taxonomy” section). Clade C represents Phaeosphaeria sensu stricto with five species, including the type species and two new species; detailed phylogenetic relationships among these species are shown in Fig. 3. Clade D represents two isolates of the genus 170 Fungal Diversity (2014) 68:159–238 Fig. 1 A Bayesian 50 % majority rule consensus tree based on combined dataset of LSU, SSU, TEF1 and RPB2 alignment.

Newly generated sequences are in red and the type species are indicated in blue Ophiosphaerella, which form a strongly supported clade (100 % ML/ 100 % MP/ 1.00 PP) separate from Ophiosphaerella herpotricha. The two strains of Ophiosphaerella agrostidis are clearly defined based on morphology (see under Ophiosphaerella agrostidis). However, the genus Ophiosphaerella is not represented by its type species. Further isolates and type strains from Ophiobolus and Ophiosphaerella are required to better resolve and naturally place these genera. Clade E comprises the genera Amarenomyces, Sclerostagonospora, and Wojnowicia plus a putative strain of Ophiosphaerella herpotricha and four strains of Phaeosphaeria. Phaeosphaeria ammophilae is not closely related to Phaeosphaeria sensu stricto, the species is reinstated as Amarenomyces, while other Phaeosphaeria taxa in this clade may need removing from Phaeosphaeria. However, the tree needs to be better populated with strains that are morphologically well-defined before adjustments can be made. Clade F comprises two strains, Phaeosphaeria alpina and Ph. typharum which are also unrelated to Phaeosphaeria sensu stricto and need further study. Clade G comprises the type species and ex-type strains of Ampelomyces and Neosetophoma, these genera also need to Fungal Diversity (2014) 68:159–238 Fig. 2 A Bayesian 50 % majority rule consensus tree based on combined dataset of ITS, LSU, SSU and RPB2 alignment.

Clade H comprises the ex-types strains and type species of Parastagonospora and, Neostagonospora, and ex-type strains Sclerostagonospora cycadis, Scolicosporium minkeviciusii and Wojnowicia viburni (the latter three species are not generic types). Three Phaeosphaeria sensu lato strains also cluster here indicating the polyphyletic nature of the genus. Clade I comprises Xenoseptoria, Setomelanomma and Paraphoma, with Xenoseptoria and Paraphoma represented by ex-type strains of their type species. Setomelanomma is closely related to Xenoseptoria which formed a robust clade (97 % ML/ 71 % MP) in our multigene phylogenetic analyses. Clade J represents Vrystaatia with single species, V. aloeicola. Clade K represents the asexual genus Setophoma with five strains, including the type species, S. terrestris. The genus is well-resolved in our phylogenetic analyses which form a strongly supported clade (100 % ML/ 64 % MP/ 1.00 PP) at the basal of Phaeosphariaceae. Figure 3 deals with the species complex of Phaeosphaeria sensu stricto and Parastagonospora. Phaeosphaeria juncicola (CBS 110108) was selected as the outgroup taxon. The newly generated strains which were collected from Thailand form a robust clade with the ex-type species, Phaeosphaeria oryzae and with Ph. papayae and Ph. musae in the Phaeosphaeria sensu stricto clade. Phaeosphaeria sensu stricto is distinguished from Parastagonospora, the Fig. 4 ITS pair wise comparison of Phaeosphaeria oryzae (CBS„ 110110), P. oryzae (RP0086; MFLUCC 11-0170), P. papayae (CBS 135416), P. thysanolaenicola (RP0036; MFLUCC 10-0563), P. chiangraina (RP0131; MFLUCC 13-0231), P. musae (CBS 120026) and P. musae (RP0049; MFLUCC 11-0133 and RP0067; MFLUCC 11-0151) Fungal Diversity (2014) 68:159–238 173 174 species having been accommodated in Phaeosphaeria and Phaeosphaeria sensu lato (Phaeosphaeria alpina and Ph. typharum). Phaeosphaeria sensu stricto taxa (MFLUCC 11-0133; MFLUCC 11-0151) cluster with Ph. musae (CBS 120026), a pathogen of banana. An ITS pair wise comparison shows that these three isolates differ in seven base positions (Fig. 4) while there are only one to two base differentiated in TEF1 gene comparisons. Isolate MFLUCC 11-0133 is slightly morphologically different from the other two isolates (MFLUCC 11-0151 and CBS 120026) in its ascus and ascospore sizes. However, these three isolates are generally similar in morphology and phylogeny. Therefore, we treat the isolates causing leaf spot disease on Calathea sp. and Cordyline sp. from Thailand as conspecific with Phaeosphaeria musae. Phaeosphaeria thysanolaenicola (MFLUCC 10-0563), a pathogen on Thysanolaena maxima, forms a clade with. Ph. chiangraina, which is saprobic on rice. These two species form strongly-supported clades which are well-resolved from the ex-type species of Phaeosphaeria oryzae. Phaeosphaeria avenaria, Ph. eustoma and Ph. nigrans form a clade with Parastagonospora species. Phaeosphaeria avenaria was synonymized under Parastagonospora avenae by Quaedvlieg et al. (2013), and the other two species may need to be synonymized under Parastagonospora based on the phylogenetic relationships. However, it was not possible to observe the types of these species or confirm if they are correctly identified. Phaeosphaeria alpina and Ph. typharum form a distinct clade from the Phaeosphaeria sensu stricto species which is separate with other Phaeosphaeria sensu lato taxa. The type species need to re-visited and a new genus may need to be introduced to accommodate these species. Taxonomy Phaeosphaeriaceae M.E. Barr Mycologia 71(5): 948 (1979). Faces of Fungi number: FoF00232 Endophytic, hyperparasitic, pathogenic, or saprobic on monocotyledonous and some dicotyledonous hosts. Sexual state: Ascomata scattered, clustered, solitary or gregarious, immersed to semi-immersed or erumpent through host tissue, small to large, uniloculate, globose to subglobose, glabrous or setose, brown to dark brown or black, ostiolate, with short to long papilla. Peridium with thin to thick walls, composed of brown to dark brown or black, pseudoparenchymatous cells, mostly arranged in a textura angularis to textura prismatica. Hamathecium composed of sparse to numerous, filamentous, septate, rarely anastomosing, mostly cellular pseudoparaphyses, or pseudoparaphyses occasionally lacking. Asci 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, or clavate, sessile to subsessile, or usually with Fungal Diversity (2014) 68:159–238 short pedicels, apically rounded with typically well-developed ocular chamber. Ascospores overlapping muriform, phragmosporous, or scolecosporous, varying in shape from ellipsoidal, fusiform to broadly fusiform, clavate, and cylindrical to filiform, mostly brown to dark brown or reddishbrown, sometimes hyaline, 1- to multi-septate, constricted or not constricted at the septum, walls smooth or rough, echinulate, punctuate or verrucose, some with appendage or mucilaginous sheath. Asexual state: Coelomycetous. Conidiomata pycnidial, scattered, solitary or gregarious, immersed to superficial, uni- to multi-loculate, globose to subglobose, glabrous or setose, light brown to dark brown or black, ostiole central, papillate. Conidiomata walls thin, composed of pseudoparenchymatous cells, arranged in a textura angularis to textura prismatica. Conidiophores lining inner cavity of the conidioma, typically reduced to conidiogenous cells, hyaline to brown, aseptate or septate. Conidiogenous cells enteroblastic or holoblastic, annellidic or phialidic, discrete, oblong to ampulliform, hyaline to brown. Conidia varied in shape, hyaline to brown, aseptate or septate, walls smooth or rough, echinulate, punctuate or verrucose, some with appendage or mucilaginous sheath. Notes: Phaeosphaeriaceae is one of the largest families in Pleosporales, and demonstrates variability in morphological characters. Previously, many genera with brown spores, associated with monocotyledonous hosts, having a thin-walled peridium and producing coelomycetous asexual states were accommodated in Phaeosphaeriaceae (Barr 1979, 1987b, 1990a, 1992a; Crivelli 1983; Schatz 1984; Shoemaker 1984; Shoemaker and Babcock 1989b; Yuan 1994; Ramaley and Barr 1995; Dianese et al. 2001; Zhang et al. 2009, 2012). Most of genera in Phaeosphaeriaceae lack molecular data or only limited sequence data is available in some genera such as Entodesmium and Phaeosphaeria. Several genera in Phaeosphaeriaceae share morphological characters with genera in other families (e.g. Didymosphaeriaceae, Leptosphaeriaceae and Pleosporaceae) and thus their placement is confused. Therefore, re-visiting all type genera of Phaeosphaeriaceae to establish their morphology and to obtain molecular sequence data from fresh collections are essential to provide modern descriptions and to determine the placement of genera in this family.

Genera are listed in alphabetical order and provided with genus description and notes, descriptions of type or authentic species, notes on species, material examined and illustrations. If the genus is monotypic, only a single description which also represents the genus is provided. Fungal Diversity (2014) 68:159–238 Key to genera of Phaeosphaeriaceae 1.

Microconidia amerosporous, blastic-phialidic, hyaline, smooth-walled (from Eriksson 1982; Nag Raj 1989). Type species: Amarenographium metableticum Phylogenetic study: Hodhod et al. (2012) Notes: Amarenographium metableticum (Trail) O.E. Erikss. is the type of Amarenographium which was introduced as the asexual state of Amarenomyces (Eriksson 1982; Nag Raj 1989; Hodhod et al. 2012). Amarenographium metableticum had previously been identified as Camarosporium metableticum which was not congeneric with C a m a ro s p o r i u m st e p h e n s i i , t he g en er i c ty pe o f Camarosporium at that time (Sutton 1980; Eriksson 1982). Therefore, Eriksson (1982) transferred Camarosporium metableticum to a new genus based on the different morphological characters (Hodhod et al. 2012; Hyde et al. 2013). Amarenographium differs from Camarosporium by its conidiophores and conidia. In Amarenographium conidiophores are longer and branched and conidia have gelatinous appendages (Eriksson 1982; Hodhod et al. 2012). Hodhod et al. (2012) introduced a new species of Amarenographium, Am. solium Abdel-Wahab et al. from mangroves and noted that Amarenographium did not belong in Phaeosphaeriaceae but clusters with Pleosporales, genera incertae sedis, while Amarenomyces formed a clade with Phaeosphaeria in Phaeosphaeriaceae (Zhang et al. 2009, 2012). However, Hodhod et al. (2012) did not study the type species and the type species of Amarenographium lacks molecular data to confirm the relationships between these genera. Thus we presently maintain the genus in Phaeosphaeriaceae. Amarenographium metableticum (Trail) O.E.

Sexual state: see notes. Asexual state: Conidiomata 160–215.5μm high, 150–270μm diam., pycnidial, scattered, solitary, immersed to erumpent, visible as black spots on host surface, uniloculate, globose to subglobose, glabrous, dark brown, ostiole central, with short to long papilla.

Sexual state: Ascomata 170– 290μm high, 170–285μm diam., scattered, immersed to erumpent through host tissue, visible as small black spots on host surface, uniloculate, globose to subglobose, glabrous, dark brown, ostiole central, with short papilla (50–130μm long). Peridium 7.5–25μm wide, thin-walled, of equal thickness, composed of 3–5 layers of flattened, dark brown, pseudoparenchymatous cells, arranged in textura angularis to textura prismatica. Hamathecium composed of numerous, 1.5–3μm wide, filiform, distinctly septate, frequently anastomosing, narrow cellular pseudoparaphyses, embedded in mucilaginous matrix. Asci (112–)140–160(−173)× (28–)30–35(−37) μm (x = 140×32.4μm, n=25), 8-spored, bitunicate, fissitunicate, broadly cylindrical, subsessile with minute knob-like pedicel, apically rounded, with a well-developed ocular chamber. Ascospores 39–47(−50)× 12–14 μm (x = 43.4 × 13.2 μm, n = 30), overlapping 1–3-seriate, phragmosporous, broadly fusiform, rarely cylindric-clavate, widest at the middle cell, pale yellowish when immature, becoming yellowish-brown to brown at maturity, 6-septate, slightly constrict at the septum, smooth and thick-walled. Material examined: BELGIUM, West-Vlaanderen, Blankenbergh, on Ammophila arenaria L. (Poaceae), Westendorp (S-F77691); ITALY, Sardegna, Cagliari, La Maddelena, March 1866, Marcucci (S-F77741). Notes: Amarenomyces was introduced by Eriksson (1981) to accommodate the single species from a marine grass, which traditionally has been identified as Sphaeria ammophilae Lasch. Eriksson (1981) mentioned that the genus should belong in Botryosphaeriaceae rather than Phaeosphaeriaceae as its morphological characters differed from Phaeosphaeria. Fungal Diversity (2014) 68:159–238 177 Fig. 5 Amarenographium metableticum (S-F207509). a Specimens and herbarium label of Amarenographium metableticum b Conidiomata visible on host surface. c Section through conidiomata. d Section through conidiomata wall. e–g Conidiogenous cells. h–k Conidia. Scale bars: c= 100μm, d=20μm, e, h, i, j, k=10μm, f, g=5μm Zhang et al. (2009) listed Amarenomyces as a synonym of Phaeosphaeria based on phylogenetic evidence. The generic type of Amarenomyces, A. ammophilae often clusters with other Phaeosphaeria species (Zhang et al. 2009, 2012; Hyde et al. 2013). Thus the earlier name as proposed by Kohlmeyer and Kohlmeyer (1965) and Leuchtmann (1984) was reinstated as Phaeosphaeria ammophilae (Suetrong et al. 2009; Zhang et al. 2009). Several Phaeosphaeria species have previously been transferred to other genera based on the phylogenetic evidence and due to their asexual state. For example Phaeosphaeria nodorum which was transferred to Parastagonospora, as Pa. nodorum. On the other hand, Shoemaker and Babcock (1989b) divided Phaeosphaeria into six subgenera by combining Phaeosphaeria species with similar morphological characters, but differing in ascospore characters, host 178 Fig. 6 Amarenomyces ammophilae (S-F77691). a Specimens and herbarium label b Ascomata visible on host surface. c Section through ascoma. d Section through peridium. e Asci with cellular Fungal Diversity (2014) 68:159–238 pseudoparaphyses. f–i Asci. j–m Ascospores. n Ascospore stained in indian ink.

The asexual state of Phaeosphaeria has been reported as Phaeoseptoria and this is supported by phylogenetic data (Quaedvlieg et al. 2013). Quaedvlieg et al. (2013) transferred Phaeosphaeria species which did not produce Phaeoseptoria asexual states to other genera. Therefore, the genus Amarenomyces is reinstated in this study based on the phylogenetic analysis as A. ammophilae forms a separate clade to the type species, Phaeosphaeria oryzae. Although A. ammophilae has often been reported to be the sexual state of Amarenographium metableticum (Trail) O.E. Erikss., they are not treated as congeneric here. The presumed link was established as both species occur on the same host in close proximity. There is, however, no sequence data for Amarenographium metableticum and it might be predicted that if both species were host-specific then it would not be surprising that they both occur on the same host. We therefore refrain from combining the taxa until molecular data confirms the link. Ampelomyces Ces. ex Schlecht., Bot. Zeit. 10: 302 (1852), Faces of Fungi number: FoF00291. Hyperparasitic on Erysiphales or saprobic. Sexual state: unknown. Asexual state: Conidiomata pycnidial, scattered, solitary, superficial, uniloculate, globose or elongated to pyriform, pale brown, ostiolate, sometimes papillate. Conidiomata walls thick, composed of pale brown cells, arranged in textura angularis. Conidiophores mostly reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, determinate, discrete, doliiform to ampulliform, hyaline, smooth-walled, channel and collarette minute, periclinal wall towards apex thickened, formed directly from the pycnidial wall cells. Conidia amerosporous, cylindrical to fusiform, straight to curved, very pale brown, aseptate, thin and smooth-walled, with guttules. (Sutton 1980) Type species: Ampelomyces quisqualis Ces., Bot. Ztg. 10: 301 (1852). Phylogenetic study: Kiss and Nakasone (1998), Szentiványi et al. (2005), Liang et al. (2007), De Gruyter et al. (2009), Aveskamp et al. (2010), Hyde et al. (2013), Wijayawardene et al.(2013a) Notes: Ampelomyces species have been reported as mycoparasites on powdery mildews (Erysiphaceae) and are worldwide in nature (de Bary 1870; Griffith 1899; Kiss 1998; Kiss et al. 2004). The genus was introduced by Cesati (1852) to accommodate taxa that formed pycnidia as intracellular mycoparasites on powdery mildews (De Bary 1870; Kiss et al. 2004). Previously, Ampelomyces had varied morphological and cultural characteristic with species differentiated based on pycnidia, cultures and conidial types in isolates of pycnidial mycoparasites from powdery mildews (Clare 1964; Belsare et al. 1980; Kiss et al. 2004). In Kiss et al. (2004), Ampelomyces species could be distinguished into slow and fast growing types. Based on the rDNA ITS region 179 phylogenetic analysis, Kiss et al. (2004) concluded that strains from the two types of differentiated growth rate were not congeneric. The slow-growing isolates, obtained from intracellular pycnidia in powdery mildew mycelia was Ampelomyces sensu stricto. While fast growing isolates from sessile pycnidia on mildew-infected leaves, were closely related to Phoma species. Ampelomyces quercinus (Syd.) Rudakov, A. humuli (Fautrey) Rudakov and A. heraclei (Dejeva) Rudakov are example of fast growing species (Rudakov 1979; Kiss and Nakasone 1998; Sullivan and White 2000). De Gruyter et al. (2009) included two isolates of the type species; A. quisqualis in their phylogenetic analysis and showed that the type species of Ampelomyces can be accommodated in Phaeosphaeriaceae. Whereas Ampelomyces quercinus grouped in Didymellaceae; thus, Aveskamp et al. (2010) introduced A. quercinus as new combination within Phoma in Didymellaceae. Bricookea M.E. Barr, Mycotaxon 15: 346 (1982), Faces of Fungi number: FoF00239. Saprobic on Juncaceae. Sexual state: Ascomata scattered or clustered, immersed to semi-immersed, becoming erumpent through host tissue or superficial at maturity, unito multi-loculate, globose to subglobose, glabrous, brown to dark brown, ostiole central, with slit-like opening. Peridium thin-walled, composed of brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, distinctly septate, broad cellular pseudoparaphyses, anastomosing at the apex. Asci 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, narrow towards apex, short pedicellate, apically rounded, with well-developed ocular chamber. Ascospores overlapping, 1–3-seriate, phragmosporous, ellipsoidal to broadly fusiform, hyaline, septate, slightly curved, constricted at the median septum, smooth and thick-walled. Asexual state: Unknown. Type species: Bricookea sepalorum Phylogenetic study: None Notes: Barr (1982) introduced Bricookea to accommodate B. sepalorum that was previously identified as Leptosphaeria sepalorum (Vleugel) Lind (Lind 1928). Holm (1957) observed the collections from Sweden and compared the morphological characters with specimens from North America. He mentioned that the ascospores and asci of Swedish collections were smaller than North American specimens and regarded the species as synonym of Lizonia emperigonia (Auersw.) de Not. (Barr 1982; Shoemaker and Babcock 1989a; Zhang et al. 2012). Barr (1982) did not agree with Holm (1957) and designated the new genus, Bricookea to accommodate Leptosphaeria sepalorum. Barr (1982) suggested placing Bricookea in Phaeosphaeriaceae with its uniquely opening ostioles and lack of known asexual state. Barr (1982) mentioned that Sphaerulina inquinans Rehm may be provided as earlier epithet of Bricookea sepalorum. 180 However, Shoemaker and Babcock (1989a) studied the type specimens of Bricookea from S herbaria and mentioned that no material was found under the name Sphaerulina inquinans. Subsequently, Shoemaker and Babcock (1989a) introduced the new species, Bricookea barrae from a North American collection which had been examined by Barr (1982). Bricookea barrae [as Br. barriae] was synonymized under the name Lophiostoma barriae in Lophiostomataceae by Eriksson (2007) leaving the genus monotypic. Zhang et al. (2012) tentatively place Bricookea in Phaeosphaeriaceae. C u r r e n t l y, B r i c o o k e a i s g e n e r a l l y t r e a t e d i n Lophiostomataceae based on its slit-like ostioles, but the type species, Br. sepalorum has been synonymized under the earlier name in Leptosphaeriaceae as Leptosphaeria sepalorum (Index Fungorum 2014). We examined the collection from North America and type specimen from S herbaria. Both collections have similar morphological characters. However, the specimens from North America differ in having larger ascoma, asci and ascospores than the type specimen from Europe. In this study, Bricookea forms a group in pseudostroma, with slit-like ostioles; characters typical of Lophiostomataceae. However, we tentatively place Bricookea in Pheaosphaeriaceae as its peridium is thinwalled, composed of pseudoparenchymatous cells, asci are clavate with a subsessile to short acute pedicel and ascospores are phragmosporous. Fresh collection, epitypification and molecular analysis are needed to confirm the natural placement. Bricookea sepalorum (Vleugel) M.E.

Peridium 10–20μm wide, thin-walled, of equal thickness, composed of 2–3 layers of large, brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, 1.5–2μm wide, filamentous, distinctly septate, cellular pseudoparaphyses, embedded in mucilaginous matrix, anastomosing at the apex.

Conidiomata walls thin, arranged in a textura prismatica, pale brown, outer layers comprising dark brown, thick-walled cells. Conidiophores arising from basal cavity of conidiomata mostly reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, discrete or integrated, cylindrical, hyaline, smooth-walled, with minute channel or collarette, hardly distinguishable from the inner wall cells. Conidia didymosporous, oblong to cylindrical, with obtuse ends, straight or slightly curved, hyaline, 1-septate, thin and smooth-walled, with guttules (from Sutton 1980; Quaedvlieg et al. 2013) Type species: Chaetosphaeronema hispidulum (Corda) Moesz, Bot.

Notes: Chaetosphaeronema was introduced by Moesz (1915) as typified by Ch. hispidulum to accommodate species of Sphaeronaema that were not congeneric. A partial morphological treatment of the genus was provided by Sutton (1980). Petrak (1944) treated Ch. herbarum (Hollós) Moesz as a synonym of Ch. hispidulum and accepted three species in Fungal Diversity (2014) 68:159–238 Fig. 7 Bricookea sepalorum (S-F49661, type). a Herbarium label and specimens b Ascomata on substrate. c Section through stroma d Section through peridium. e Asci with cellular pseudoparaphyses strained 181 in cotton blue reagent. f–g Asci. h–i Asci stained in cotton blue reagent. j Ascospores. k–n Ascospores.

H o w e v e r, Chaetosphaeronema was subsequently limited to the type species (De Gruyter et al. 2009, 2010; Zhang et al. 2012; Hyde et al. 2013; Quaedvlieg et al. 2013). De Gruyter et al. (2009) showed, using molecular data that Chaetosphaeronema was related to Phaeosphaeriaceae and Pleosporaceae. De Gruyter et al. (2010) introduced a new species, Ch. coonsii (Boerema & Loer.) Gruyter et al., and treat e d Chaetosphaeronema sensu s tricto i n Phaeosphaeriaceae. This placement has been widely accepted by subsequent authors based on the phylogenetic evidence, while no sexual state is presently known (Schoch et al. 2009; Zhang et al. 2009, 2012; Hyde et al. 2013; Quaedvlieg et al. 2013). In this study, Chaetosphaeronema clusters with various sexual genera and is closely related to Ophiobolus cirsii (MFLUCC13-0218) as propose by Petrak (1944) and Zhang et al. (2009) who suggested that Chaetosphaeronema may be asexual state of Ophiobolus. The link between these genera has not yet equivocally been proven. Epitypification with molecular data is therefore needed to confirmed the natural placement of these genera and confirm asexual-sexual connections. Dematiopleospora Wanasinghe et al., Cryptog. Mycol. 35 (2): 105-11(2014), Faces of Fungi number: FoF00242. Saprobic on Ononis spinosa L (Fabaceae). Sexual state: Ascomata scattered, solitary, superficial, uniloculate, globose to subglobose, glabrous, dark brown to black, coriaceous, cupulate when dry, ostiole central, minute papilla, with thick, brown, periphyses. Peridium thin-walled, composed of pseudoparenchymatous cells, outer layer comprising heavily pigmented, thick-walled, reddish to dark brown cells, arranged in textura angularis, inner layer comprising 2–3 cell layers of thin-walled, hyaline cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, distinctly septate, broad cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, short pedicellate, apically rounded with minute ocular chamber. Ascospores overlapping 1–2-seriate, dictyosporous, muriform, ellipsoidal to subfusiform, widest in the upper part, slightly curved, 5–9 transverse septa, with 3– 6 longitudinal septa, constricted at the central septum, initially hyaline, becoming yellowish-brown at maturity, smoothwalled. Asexual state: Unknown (from Wanasinghe et al. 2014) Type species: Dematiopleospora mariae Wanasinghe et al., Cryptog. Mycol. 35 (2): 105-11(2014) Phylogenetic study: Wanasinghe et al. (2014). Notes: Dematiopleospora was introduced by Wanasinghe et al. (2014) to accommodate D. mariae. The genus is characterized by thick, brown, periphyses in the ostiole, superficial ascomata and muriform ascospores. Dematiopleospora is Fungal Diversity (2014) 68:159–238 similar to Nodulosphaeria in its periphysate ostiole, but they differ in peridium structure and ascospore morphology. Dematiopleospora has muriform ascospores similar to those characterized in Phaeosphaeria vagans (Niessl) O.E. Erikss., Ph. phragmiticola Leuchtm., Ph. phragmitis (Hollós) Leuchtm and Pleoseptum yuccaesedum A.W. Ramaley & M.E. Barr (Shoemaker and Babcock 1989b; Z h a n g e t a l . 2 0 1 2 ; Wa n a s i n g h e e t a l . 2 0 1 4 ) . Dematiopleospora is similar to Pleoseptum, but they differ in peridium structures and papillate ostioles. Pleoseptum lacks of molecular data to confirm its natural placement. Therefore, the genus is tentatively placed in Pleosporaceae based on its muriform ascospores and thick-walled peridium that are dominant characters in Pleosporaceae. Multigene phylogenetic analyses indicated that Dematiopleospora belongs to Phaeosphaeriaceae which forms a separate clade from those Phaeosphaeria s p e c i e s a n d g r o u p s w i t h C h a e t o s p h a e ro n e m a , Entodesmium, Loratospora and Nodulosphaeria. No asexual morph is known for Dematiopleospora. Dothideopsella Höhn., Sber. Akad. Wiss. Wien, Math.naturw.

Sexual state: Ascomata scattered, gregarious, immersed to semi-immersed, or erumpent, nearly superficial, globose, uniloculate, subglobose or obypyriform, glabrous, dark brown to black, ostiole central, broadly or narrowly conical, with a dark brown to black papilla. Peridium thin to thick, of unequal thickness, slightly thick at the basal ascoma, composed of dark brown to black, thin-walled, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, distinctly septate, cellular pseudoparaphyses, anastomosing without a gelatinous coating. Asci 8-spored, bitunicate, fissitunicate, cylindrical to oblong, with a knob like pedicel, apically rounded with welldeveloped ocular chamber Ascospores phragmosporous, ellipsoidal to fusiform, brown or yellowish brown, septate, slightly constricted at the septum, smooth-walled. Asexual state: Unknown (from Ariyawansa et al. 2013). Type species: Dothideopsella agminalis (Sacc. & Morthier) Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 124: 70 (1915) Phylogenetic study: None Notes: Dothideopsella was introduced by Höhnel (1915) and is typified by Dothideopsella agminalis (Sacc. & Morthier) Höhn. The genus was established to accommodate Dothideomycetes species characterized by a broad peridium structure, with conical, papillate ostioles, and phragmosporous, brown ascospores (Ahn and Shearer 1998; Ariyawansa et al. 2013). Lumbsch and Huhndorf (2010) treated Dothideopsella in Dothideomycetes, genera incertae sedis, while Index Fungorum (2014) lists the genus in Fungal Diversity (2014) 68:159–238 Leptosphaeriaceae. Ariyawansa et al. (2013) tentatively placed Dothideopsella in Phaeosphaeriaceae based on its morphological characters which are typical of Chaetoplea. Dothideopsella however differs from Chaetoplea in having a peridium composed of pseudoparenchymatous cells, while the peridium in Chaetoplea is composed of scleroplectenchymatous cells. The placement of the genus in Phaeosphaeriaceae was supported by Wijayawardene et al. (2014b). Thus we tentatively place Dothideopsella in Phaeosphaeriaceae until molecular date proves otherwise. Entodesmium Riess, Hedwigia 1(6): 28 (1854), Faces of Fungi number: FoF00243. Saprobic or parasitic? on various dicotyledonous and some monocotyledonous hosts. Sexual state: Ascomata scattered, solitary to gregarious, immersed to erumpent through host tissue with long neck, uniloculate, globose to subglobose, glabrous, dark brown to black, ostiole central, with long neck. Neck with thick walls of textura angularis, dark brown to black, cylindrical to cylindric-clavate, carbonaceous, with periphyses. Peridium thick-walled, composed of brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, distinctly septate, broad cellular pseudoparaphyses, not constricted at the septa and anastomosing at the apex. Asci 8-spored, bitunicate, cylindrical to cylindric-clavate, short pedicellate, apically rounded, with well-developed ocular chamber. Ascospores fasciculate, scolecosporous, filiform or filamentous, initially hyaline to pale brown, becoming brown or reddish-brown at maturity, multi-septate, constricted at the septa, separating into numerous part spores, smooth-walled. Asexual state: Unknown. Type species: Entodesmium rude Phylogenetic study: Liew et al. (2000), Schoch et al. (2009), Zhang et al. (2009, 2012) Notes: Entodesmium was introduced by Riess (1854) and is typified by E. rude. The genus was introduced to accommodate a Dothideomycete species with long beaked ascomata and scolecosporous ascospores, which break into numerous part-spores and occur on legumes. The placement of Entodesmium was previously unclear as Von Arx and Müller (1975) disposed the genus in Pleosporaceae, while Barr (1987b) suggested that Entodesmium should be placed in Phaeosphaeriaceae and this was accepted by Eriksson and Hawksworth (1991). Barr (1992b) assigned Entodesmium to Lophiostomataceae based on its short, blackish beak and periphysate ostiole. Barr (1992b) mentioned that these characters are more typical of Lophiostomataceae. Zhang et al. (2009, 2012) disagreed with Barr (1992b) and mentioned that the morphological characters of Entodesmium best fit in Phaeosphaeriaceae. Entodesmium was thought to be family-specific and associated only with legumes (Barr 1992b; Shoemaker 1984; Zhang et al. 2009, 2012). Holm (1957) and Shoemaker 183 (1984) re-described Entodesmium and reported six species associated with legumes from Europe; although, Wehmeyer (1952) identified some collections from North America (Barr 1992b). Furthermore, there is a report of E. niesslianum from Dieffenbachia (monocotyledon) in West Indies by Minter et al. (2001) in Farr and Rossman (2014). Six species are presently accommodated in Entodesmium; E. eliassonii L. Holm, E. lapponicum (L. Holm) L. Holm, E. mayorii (E. Müll.) L. Holm, E. nevadense Petr., E. niesslianum (Rabenh. ex Niessl) L. Holm and E. rude (Index Fungorum 2014). Entodesmium multiseptatum (G. Winter) L. Holm was assigned to Leptosphaeriaceae and Entodesmium vermisporum (Ellis) M.E. Barr (1992b) was treated in Lophiostomataceae (Winter 1872; Barr 1992b; Zhang et al. 2009, 2012; Index Fungorum 2014). However, Zhang et al. (2009, 2012) mentioned that E. multiseptatum and E. niessleanum are more similar to Phaeosphaeria than Leptosphaeria or Entodesmium. Zhang et al. (2009) accepted the scolecosporous genera Entodesmium and Ophiosphaerella in Phaeosphaeriaceae based on phylogenetic evidence. Multigene phylogenetic analysis based on this sequence data has indicated that Entodesmium belongs to Phaeosphaeriaceae which has been widely accepted (Schoch et al. 2009; Zhang et al. 2009, 2012; Hyde et al. 2013). In this study, the iconotype is re-drawn while the type specimens could not be located. Based on morphology (thinwalled peridium composed of pseudoparenchymatous cells, and scolecosporous, brown, multi-septate ascospores breaking into part-spores) and multigene phylogenetic analysis, we retain Entodesmium in Phaeosphaeriaceae. Entodesmium forms a weakly-supported clade with other genera (Chaetosphaeronema, Dematiopleospora, Loratospora, Nodulosphaeria modesta, Ophiobolus cirsii and O. erythrosporus) in Phaeosphaeriaceae. However, the sequence data is from a putative strain of Entodesmium rude from CBS, thus epitypification and molecular work is needed to confirm its natural placement.

Type species: Eudarluca australis Phylogenetic study: None Notes: Eudarluca was introduced by Spegazzini (1908) and typified by Eu. australis which is associated with a rust on leaves of Canna. Eriksson (1966) treated Eu. australis as a synonym of Eudarluca caricis (Fr.) O.E. Erikss. Eudarluca caricis has been reported from various hosts, mostly in its presumed asexual state, Sphaerellopsis (Yuan et al. 1998; Nischwitz et al. 2005; Zhang et al. 2012). The asexual and sexual state connection between Eudarluca caricis and Sphaerellopsis filum was derived from ascospores growing on Puccinia extensicola-oenotherae (Mont.) Arthur on Carex sp. in Pennsylvania, USA (Keener 1951) and confirmed by Yuan et al. (1998). Yuan et al. (1998) grew ascospores of Eudarluca caricis on PDA and derived Sphaerellopsis conidia and conidiomata after 12 days. Zhang et al. (2012) compared the ITS sequence of Eudarluca caricis strain MullMK in GenBank with Leptosphaeria species and mentioned that Eudarluca should be treated in Leptosphaeriaceae due to comparable sequences and also morphological characters. However, both the generic type of Eudarluca and Sphaerellopsis have never been linked (Wijayawardene et al. 2014b). Molecular studies on Eudarluca are limited to species variation and are based on Sphaerellopsis strains (Nischwitz et al. 2005; Bayon et al. 2006; Zhang et al. 2012). The ITS gene phylogenetic analysis showed that Eudarluca ciricis (strains MosID6 and MullMK) cluster in Leptosphaeriaceae. However, the generic type of Sphaerellopsis has found on Quercus, while the type of Eudarluca is from Canna. These two generic types have not been linked by molecular data. We suggest that caution should be followed when treating these taxa, as Eu. australis is immersed in the Canna leaves and although associated with the rust fungi (Sphaerellopsis) on Canna, it does not seem to grow on the rust. In this study, we tentatively place Eudarluca in Phaeosphaeriaceae based on its morphological characters which are typical of Phaeosphaeria as the peridium is thin-walled, and composed of pseudoparenchymatous cells, asci are cylindrical, subsessile to short pedicellate and ascospores are fusiform and phragmosporous. Fresh collections of Eu. australis are needed for epitypification and molecular study. Sphaerellopsis may belong in Leptosphaeriaceae where it is tentatively assigned.

Kohlmeyer and Volkmann-Kohlmeyer (1993) mentioned that the species often developed on culms which were not regularly submerged in salt water. Loratospora is similar to Leptosphaerulina (Didymellaceae), Monascostroma (Didymellaceae) and Wettsteinina Fungal Diversity (2014) 68:159–238 (Dothideomycetes genera incertae sedis), but Leptosphaerulina and Monascostroma have smaller ascomata, lack periphyses, and have a thin-walled peridium. Ascospores in Leptosphaerulina are muriform and didymosporous in Monascostroma (Kohlmeyer and Volkmann-Kohlmeyer 1993; Jones et al. 2009). Loratospora forms large ascomata with brown ostiolar periphyses, a thick-walled peridium at the apex and phragmosporous, cylindrical ascospores (Kohlmeyer and Volkmann-Kohlmeyer 1993; Jones et al. 2009; Suetrong et al. 2009). Wettsteinina differs from Loratospora in lacking ostiolar periphyses, in having a thick-walled peridium of equal width and ellipsoidal to broadly fusiform ascospores (Kohlmeyer and Volkmann-Kohlmeyer 1993) Loratospora was re-circumscribed by Jones et al. (2009) and Monkai et al. (2013). The genus was accommodated in Planistromellaceae by Barr (1996) due to its periphysate ostiole (Jones et al. 2009; Suetrong et al. 2009; Monkai et al. 2013). Based on multigene phylogenetic analysis, Loratospora was placed in Phaeosphaeriaceae (Schoch et al. 2009; Zhang et al. 2012; Hyde et al. 2013). In the multigene phylogenetic analyses (Fig. 2), Loratospora forms a strongly supported clade with Chaetosphaeronema, Dematiopleospora, Entodesmium, Nodulosphaeria and Ophiobolus. However, the genus has a differentiated centrum type as compared with other genera. Loratospora lacks of pseudoparaphyses but has an internal mucilaginous hamathecium, while most genera in Phaeosphaeriaceae have pseudoparaphyses. It seem like the centrum-type is not significant to distinguish genera at the family level. There is only one species listed in Loratospora in Index Fungorum (2014) and no asexual state is known. The sequences data of Loratospora is limited to only one strain. Neosetophoma Gruyter et al., in Gruyter et al. Mycologia 102(5): 1075 (2010), Faces of Fungi number: FoF00249.

The genus has been widely accepted in Phaeosphaeriaceae by various authors (De Gruyter et al. 2010, 2012; Zhang et al. 2012; Hyde et al. 2013; Quaedvlieg et al. 2013).

Conidiogenous cells phialidic, integrated, ampulliform to doliiform, hyaline, smooth-walled, lining the inner cavity, with prominent periclinal thickening. Conidia narrow fusoid-ellipsoidal to subcylindrical, apically subobtuse to rounded, truncate at the base, hyaline, septate, initially nonconstricted at the septum, becoming constricted at the septa when mature, smooth-walled, with granules (from Quaedvlieg et al. 2013). Type species: Neostagonospora caricis Quaedvlieg et al., Stud. Mycol. 75: 364 (2013). Phylogenetic study: Quaedvlieg et al. (2013). Notes: The asexual genus Neostagonospora was introduced by Quaedvlieg et al. (2013) to accommodate the stagonospora-like species in Phaeosphaeriaceae. Two species were placed in this genus; Neostagonospora caricis and Ne. elegiae Quaedvlieg et al. with Ne. caricis being the type species. Neostagonospora is similar to Stagonospora but differs in its conidiogenous cells. Neostagonospora has determinate phialidic conidiogenous cells, with prominent periclinal thickening while Stagonospora has percurrent proliferation of conidiogenous cells. Based on phylogenetic analysis, Neostagonospora is related to Phaeosphaeriaceae, while the type species of Stagonospora, St. paludosa clusters in Massarinaceae (Quaedvlieg et al. 2013). In the phylogeny in Fig. 2, Neostagonospora forms a sister clade with Parastagonospora for which no sexual state is known. Phaeosphaeria sensu lato taxa are polyphyletic and therefore, it is likely that Neostagonospora may be an asexual state of phaeosphaeria-like species. Nodulosphaeria Rabenh., Klotzschii Herb. Viv.

Type species: Nodulosphaeria hirta Phylogenetic study: this study. Notes: Nodulosphaeria was introduced by Rabenhorst (1858) to accommodate Dothideomycete species forming phragmosporous, brown, septate ascospores with an enlarged cell, and setose ascomata with broad setae in the papilla apex, mostly found on herbaceous dicotyledonous especially Asteraceae (Shoemaker 1984; Zhang et al. 2012). Nodulosphaeria has been reported from various hosts and may be host-specific with more than 60 species named, however it is lacking in molecular data (Shoemaker 1984). The genus was previously treated as a synonym of Leptosphaeria, but later reinstated by Holm (1957) as typified by N. hirta (Clements and Shear 1931; Zhang et al. 2012). Nodulosphaeria was treated in Phaeosphaeriaceae by Barr (1979) based on its morphological characters which are similar to Ophiobolus as the ascospores form an enlarged cell(s). The genera have often been confused and the identification of species can be subjective (Zhang et al. 2012). Shoemaker (1976) re-circumscribed the genus Nodulosphaeria and transferred various species to Ophiobolus. Later many species were added to Nodulosphaeria based on morphology by various authors, but no asexual morph is known (Shoemaker 1984; Shoemaker and Babcock 1987; Zhang et al. 2012). There are 64 epithets listed under Nodulosphaeria and unfortunately no sequences available for this genus in GenBank. Multigene phylogenetic analyses (Figs. 1 and 2) indicate that Nodulosphaeria belongs in Phaeosphaeriaceae. The genus clusters with Chaetosphaeronema, Dematiopleospora, Entodesmium, Loratospora and Ophiobolus. Nodulosphaeria hirta Rabenh., Klotzschii Herb. Viv. Mycol., Edn 2: no. 725 (in sched.)

Peridium thick-walled, composed of dark brown to black, scleroplectenchymatous cells, arrange in textura angularis to textura globulosa. Hamathecium composed of numerous, filiform, cellular pseudoparaphyses, with distinct septa, anastomosing at the apex.

Ascospores fasciculate, 3–4-seriate, scolecosporous, filiform or filamentous, with enlarged central cells, yellowish-brown to brown, multi-septate, nonconstricted at the septa, separating into two part spores, smooth-walled, with or without appendages. Type species: Ophiobolus disseminans Phylogenetic study: Dong et al. 1998; Ariyawansa et al. (2014c) Notes: Ophiobolus was introduced by Riess (1854) and typified by O. disseminans. Ascomata were described as discrete with distinct ostioles and ascospores as filiform and multi-septate (Zhang et al. 2012). Ophiobolus has been found on a wide range of hosts, mostly reported from Europe and North America (Farr and Rossman 2014). Holm (1948) and Müller (1952) used a broad concept of the genus Ophiobolus; 193 however, Holm (1957) treated Ophiobolus in a much narrower sense, based on European collections (Shoemaker 1976). Three species were accepted by Holm (1957) and most Ophiobolus species were transferred to Nodulosphaeria and Leptospora (Holm 1957; Shoemaker 1976; Zhang et al. 2012). Shoemaker (1976) re-circumscribed species of Ophiobolus from Canada and some North American collections and accepted 31 species with two new species and five new combinations. Walker (1980) provided various illustrations of scolecosporous taxa from type material which had previously been accommodated in Ophiobolus (Saccardo 1883; Zhang et al. 2012). Ophiobolus species were also transferred to Acanthophiobolus, Entodesmium, Gaeumannomyces, Leptosphaeria and Leptospora (Shoemaker 1976; Walker 1980; Zhang et al. 2012). Barr (1979) initially accommodated Ophiobolus in Phaeosphaeriaceae and later transferred it to Leptosphaeriaceae (Barr 1987b). However, Zhang et al. (2012) reinstated the genus in Phaeosphaeriaceae based on morphological characters which are similar to Nodulosphaeria and Ophiosphaerella. There are 357 epithets listed in Ophiobolus in Index Fungorum (2014). There is very little sequence data for Ophiobolus available in GenBank with two sequences of O. fulgidus. Zhang et al. (2012) mentioned that the genus should be placed in Phaeosphaeriaceae based on morphology and the phylogenetic investigation of Dong et al. (1998). However, Dong et al. (1998) could not resolve the placement of Ophiobolus as too few strains were used in their molecular analysis. Thus the genus needs to re-circumscribed using fresh collections (Zhang et al. 2012). The asexual state of Ophiobolus has been reported in several genera such as coniothyrium-like, Rhabdospora, phoma-like and Scolecosporiella (Shoemaker 1976; Sivanesan 1984; Hyde et al. 2011; Wijayawardene et al. 2012; Zhang et al. 2012). However, these need confirmation as Ophiobolus is probably polyphyletic. In this study, two species of Ophiobolus are included in the phylogenetic analysis. The detailed descriptions are provided in Ariyawansa et al. (2014c) and a description of the generic type is provided below. Based on multigene phylogenetic analysis (Figs. 1 and 2), Ophiobolus clusters in Phaeosphaeriaceae. However, there are limited sequences in GenBank and the type species lacks molecular data to confirm its natural placement. Thus Ophiobolus is tentatively placed in Phaeosphariaceae until the generic type strain is sequenced to confirm the natural placement (Table 2).

(2006, 2009), Zhang et al. (2009, 2012), Hyde et al. (2013). Notes: Ophiosphaerella was introduced by Spegazzini (1909) as typified by Op. graminicola. Most species of Ophiosphaerella are often found as pathogens or saprobes worldwide on Poaceae and Cyperaceae (Câmara et al. 2000). Spegazzini (1909) did not introduce the genus separately but described and illustrated a new species, and later the genus was validly published by Stafleu et al. (1972) (Walker 1980; Zhang et al. 2012). However, Petrak and Sydow (1936) treated Ophiosphaerella graminicola as a synonym of Ophiobolus graminicolus (Speg.) after observing the type specimens which was accepted by Ainsworth et al. (1971) and von Arx and Müller (1975) (Walker 1980; Zhang et al. 2012). Walker (1980) examined the type specimens of Ophiosphaerella and confirmed that the genus belongs to Pleosporales, but differs from Ophiobolus. Ophiosphaerella is most similar to Ophiobolus and subsequently often confused in morphological characters. However Ophiosphaerella differs from Ophiobolus by the lack of central swollen ascospore cells which do not separate into part spores (Zhang et al. 2012). The phylogenetic relationships of Ophiosphaerella were first investigated by Wetzel et al. (1999) who treated Ophiosphaerella as monophyletic genus distinguished from Fungal Diversity (2014) 68:159–238 Phaeosphaeria and other pleosporaceous genera. Various authors subsequently accepted the genus in Phaeosphaeriaceae based on the multigene phylogenetic investigation with Ophiosphaerella forming a monophyletic clade as a sister group of Phaeosphaeria (Schoch et al. 2006, 2009; Zhang et al. 2009, 2012; Hyde et al. 2013). However, the phylogenetic analysis was limited to one strain (Ophiosphaerella herpotricha CBS 620.86). In the present multigene phylogenetic analyses, two strains of Ophiosphaerella agrostidis (MFLUCC 11-0152 and MFLUCC 12-0007) and Op. herpotricha (CBS 620.86) are included. The phylogenetic relationships show that Op. agrostidis (MFLUCC 11-0152 and MFLUCC 12-0007) forms a distinct clade separated from Op. herpotricha (CBS 620.86) in Phaeosphaeriaceae. Thus Ophiosphaerella seem to be polyphyletic genus. However, there are few sequences available in GenBank, thus fresh collections and molecular data are needed to for more natural understanding.

Notes: The scolecosporous specimens were collected from dead culms of grass in Thailand. These collections are morphologically similar to Ophiosphaerella agrostidis, Op. graminicola, and Op. herpotricha with these species sharing similar ascomata, asci and ascospores, including septation of ascospores. The Thailand collections are most similar to Op. agrostidis according to the size of the ascomata, asci and ascospores, and also the septation of ascospores. However, Op. agrostidis has been reported as a pathogen on grass while the collections in the present study were saprobes. Therefore these collections are named as Op. agrostidis based on the morphological characters and these can be treated as authentic specimens until epitypification. The phylogenetic tree (Figs. 1 and 2) shows that two isolates of Op. agrostidis form a single clade in Phaeosphaeriaceae (Table 3). Paraphoma Morgan-Jones & J.F.

Notes: Paraphoma as typified by P. radicina was previously treated in Pyrenochaeta by McAlpine (1902) and later, Boerema and Dorenbosch (1979) transferred the species to Phoma. Morgan-Jones and White (1983) introduced a new genus, Paraphoma to accommodate the species that produced heavily setose pycnidia and transferred P. radicina to this genus. However, the genus was treated as a section of Phoma (Boerema 1997) until De Gruyter et al. (2010) reinstated the genus and placed it in Phaeosphaeriaceae based on phylogenetic evidence. Recently, four species are accommodated in this genus for which no sexual state is known. 200 Fungal Diversity (2014) 68:159–238 Fig. 18 Ophiosphaerella agrostidis (MFLU 11-0188). a Ascomata on host surface. b Section through ascoma c Section through peridium. d Cellular pseudoparaphyses stained in congo red. e–i Asci. j–n Ascospores.

(2013) Notes: Parastagonospora was introduced by Quaedvlieg et al. (2013) to accommodate stagonospora-like species which have been reported as asexual state of phaeosphaeria-like taxa. The genus accommodated five species; Pa. avenae (A.B..

Quaedvlieg et al., Pa. poae Quaedvlieg et al. and Pa. poagena Crous & Quaedvlieg with Pa. nodorum as the type (Index Fungorum, 2014). Parastagonospora is similar to Stagonospora; however, they differ in the morphology of the conidiogenous cells (Quaedvlieg et al. 2013). Based on multigene phylogenetic analysis, Parastagonospora clusters in Phaeosphaeriaceae which forms a clade with Phaeosphaeria avenaria (synonymized under Parastagonospora avenae), Ph. eustoma and Ph. nigrans. These Phaeosphaeria species may be the sexual states of Parastagonospora. Phaeosphaeria I. Miyake, Bot. Mag., Tokyo 23: 93 (1909), Faces of Fungi number: FoF00233. = Phaeoseptoria Speg., Revta Mus.

Type species: Phaeosphaeria oryzae Phylogenetic study: Câmara et al. (2002); Schoch et al. (2006, 2009); Zhang et al. (2009, 2012); De Gruyter et al. (2010, 2012); Quaedvlieg et al. (2013); Hyde et al. (2013, 2014); Wijayawardene et al. (2014b) Notes: Phaeosphaeria was established by Miyake (1909). Miyake (1910) accommodated Phaeosphaeria in Mycosphaerellaceae and mentioned that the genus differs from Sphaerulina and Leptosphaeria in ascospore colour and lack of pseudoparaphyses (Eriksson 1967). Phaeosphaeria was considered as a synonym of Leptosphaeria for a long time (Müller 1950; Munk 1957; Zhang et al. 2009, 2012). The genus was however, reinstated by Holm (1957) who found pseudoparaphyses in Phaeosphaeria oryzae and 17 mostly graminicolous species were transferred to Phaeosphaeria (Eriksson 1967; Zhang et al. 2009). Barr (1979) established the new family Phaeosphaeriaceae and designated Phaeosphaeria as the generic type and later, Eriksson (1981) introduced a broad generic concept for Phaeosphaeria which included relatively small ascomata, dictyospores, as well as ascospores with several wall layers, and an occurrence on monocotyledons (Câmara et al. 2002; Zhang et al. 2012). Subsequent authors also included Phaeosphaeria species from dicotyledonous hosts (Dennis 1978; Sivanesan 1984; von Arx and Müller 1975; Eriksson 1967; Hedjaroude 1969; Shoemaker and Babcock 1989b; Zhang et al. 2012). Shoemaker and Babcock (1989b) re-circumscribed Phaeosphaeria and divided the genus into six subgenera based on the differences in ascospore shape and septation viz. Fusispora, Ovispora, Phaeosphaeria, Sicispora, Spathispora and Vagispora. Various authors subsequently indicated that Phaeosphaeria was heterogeneous and shared several characters with Leptosphaeria. Phaeosphaeria however, differs from Leptosphaeria in morphology and these genera have been distinguished in different families by phylogenetic analysis (Câmara et al. 2002; Schoch et al. 2009; Zhang et al. 2009, 2012; Hyde et al. 2013). Presently, there are 200 epithets for Phaeosphaeria in Index Fungorum (2014) with 18,983 nucleotide sequences available in GenBank. However, several species of Leptosphaeria sensu stricto and Phaeosphaeria are confused in having similar morphology and lack phylogenetic investigation. Fungal Diversity (2014) 68:159–238 The asexual states of Phaeosphaeria have been reported as coelomycetes and some as hyphomycetes namely hendersonia-like, Mauginiella, Microsphaeropsis, Neostagonospora, Parastagonospora, Phaeoseptoria, Scolecosporiella and stagonospora-like (Leuchtmann 1984; Shoemaker and Babcock 1989b; Câmara et al. 2002; Abdullah et al. 2005; Kirk et al. 2008; Hyde et al. 2011, 2013; Wijayawardene et al. 2012; Zhang et al. 2012; Quaedvlieg et al. 2013). However, Leuchtmann (1984) treated the asexual state of Phaeosphaeria as species of Stagonospora and mentioned that the asexual state of Phaeosphaeria often formed pycnidial conidiomata, possessed holoblastic conidiogenous cells and had elongated to filiform, hyaline to pale brown, multiseptate conidia, which was also mentioned by Câmara et al. (2002). Câmara et al. (2002) suggested that Phaeosphaeria shares common ancestors with Leptosphaeria and that multigene phylogenetic analysis was necessary to understand the boundaries of taxa. The peridium type, asexual state and host preferences can distinguish fungal taxa in these two genera (Câmara et al. 2002) Quaedvlieg et al. (2013) studied Septoria, Stagonospora and related genera such as Phaeosphaeria and Phaeoseptoria using molecular analysis and concluded that Stagonospora (based on the type species, S. paludosa) belongs to Massarinaceae. They introduced two new genera (Neostagonospora and Parastagonospora) to accommodate stagonospora-like genera in Phaeosphaeriaceae (Quaedvlieg et al. 2013). Additionally, Phaeosphaeria was linked to the asexual state Phaeoseptoria based on the phylogenetic analysis with the type species of Phaeosphaeria, Ph. oryzae forming a well-supported clade with Phaeoseptoria papayae, the type species of Phaeoseptoria (Quaedvlieg et al. 2013). Thus Quaedvlieg et al. (2013) synonymized the earlier name Phaeoseptoria under Phaeosphaeria as the latter was wellstudied and taxonomy less confused than Phaeoseptoria which have been confused with several septoria-like in pigmented conidia (Walker et al. 1992). Hendersonia, which was treated as a synonym of Stagonospora, and Microsphaeropsis were placed in Didymellaceae (Sutton 1977; Swart and Walker 1988; Kirk et al. 2008; De Gruyter et al. 2009; Aveskamp et al. 2010). Mauginiella was treated as an asexual state of Phaeosphaeria by Abdullah et al. (2005); however, this has not been confirmed by phylogenetic investigation. In this study Mauginiella could not be resolved in Phaeosphaeriaceae. The genus is currently placed in asexual Pezizomycotina (Kirk et al. 2008). Therefore we exclude Mauginiella from Phaeosphaeriaceae. Other asexual genera of Phaeosphaeria still lack phylogenetic investigation. Therefore we accept three asexual genera (Neostagonospora Quaedvlieg et al., Parastagonospora Quaedvlieg et al., and Phaeoseptoria Speg.) for Phaeosphaeria sensu lato. Phaeosphaeria oryzae was designated as typified of Phaeosphaeria by Miyake (1909). However, Miyake (1909) Fungal Diversity (2014) 68:159–238 did not mention the detail of the type specimen in his publication and this type has not been found in any herbarium in Japan. Eriksson (1967) translated the protologue and found Miyake’s specimen in Sydow’s herbarium as labeled “Leptosphaeria oryzae Hori=Phaeosphaeria oryzae Miy. — on Oryza sativa L. — Prov. Susuya Shizuoka — 1907.09”. He found that most characters of this specimen match with the diagnosis except the presence of pseudoparaphyses. Thus Eriksson (1967) designated Sydow’s specimen as a lectotype of Phaeosphaeria oryzae. However, the mucilaginous sheath or appendages were not seen in Eriksson’s (1967) observation (Shoemaker and Babcock 1989b). Shoemaker and Babcock (1989b) carried out a monograph of Phaeosphaeria with Phaeosphaeria oryzae treated in subgenus Phaeosphaeria. The species description included echinulate ascospores; however Miyake (1909, 1910) and Eriksson (1967) did not mention this character. Quaedvlieg et al. (2013) epitypified Phaeosphaeria oryzae and Phaeoseptoria papayae, the type species of Phaeosphaeria and Phaeoseptoria and indicated that Phaeoseptoria is the asexual state of Phaeosphaeria based on phylogenies. In the present study the lectotype of Phaeosphaeria oryzae was examined and the morphological characters compared with the diagnosis of Miyake (1910). On examination it appears that Phaeosphaeria oryzae lectotype has smoothwalled ascospores, but this was not mentioned by Miyake (1910) either. In addition, the asci and ascospores size in the lectotype are larger than Miyake’s diagnosis (1910) (see Table 4). Quaedvlieg et al. (2013) epitypified Phaeosphaeria oryzae and described the ascospores as echinulate following the description of Shoemaker and Babcock (1989b). Further specimens that have been determined to be Phaeosphaeria oryzae from BPI have been examined in the present study and some specimens have echinulate ascospores, while others do not. It appears that Phaeosphaeria oryzae may be a species complex which has been epitypified by a specimen that is probably a different species to the lectotype. Based on our multigene phylogenetic analysis, Phaeosphaeria species separated in several subclades in Phaeosphaeriaceae. Several Phaeosphaeria sensu stricto specimens collected from various hosts in Thailand formed a strongly supported clade with the type species, Phaeosphaeria oryzae and also Ph. papayae and Ph. musae. These Phaeosphaeria (sensu stricto) species differ morphologically (see Table 4), but the phylogenies indicate that they are closely related species. We therefore analyzed the phylogenetic relationships among species, with Phaeosphaeria sensu stricto strains forming a distinct clade with high bootstrap support. A pair wise comparison of ITS and TEF1 helped to significantly differentiate the cryptic species (ITS pair wise comparison see Fig. 4). Currently, many plant pathogens causing serious disease of economic crops are reported as the species 203 complexes (Wikee et al. 2011; Cannon et al. 2012; Manamgoda et al. 2012; Udayanga et al. 2012; Weir et al. 2012) which seem to be the case in Phaeosphaeria. Phaeosphaeria sensu stricto species are morphologically similar, but differ in the size of ascomata, asci, and ascospores, habitat and host occurrence. The combined gene phylogenetic analysis can distinguish taxa of Phaeosphaeria sensu stricto at the species level. The Phaeosphaeria sensu stricto taxa collected from various monocotyledons in Thailand are introduced as two novel species and Phaeosphaeria musae is reported on other hosts from Thailand with descriptions and illustrations below.

This is the same host of the generic type of Phaeosphaeria, P. oryzae. A morphological comparison based on species described in Shoemaker and Babcock Fungal Diversity (2014) 68:159–238 (1989b) shows that Ph. chiangraina is similar to Phaeosphaeria avenaria, Ph. eustoma, Ph. oryzae and Ph. tritici. Phaeosphaeria chiangraina differs from Ph. oryzae in the size of ascomata, asci and ascospores. Phaeosphaeria chiangraina has smaller ascospores (13.5–18×3.5–4.5μm) than Ph. oryzae (15–23×4–5μm). Phaeosphaeria tritici has similar sized ascospores to Ph. chiangraina; however, Ph. tritici has a larger asci and smaller ascomata. Additionally, Phaeosphaeria tritici ascospores are enlarged at the second cell and slightly constricted at the first septa and produce a phoma-like asexual state, as while Ph. chiangraina lacks an enlarged cell, is not constricted at the septa and forms a septoria-like asexual state. Multigene phylogenetic analysis using MP shows that Phaeosphaeria chiangraina can be distinguished from Phaeosphaeria avenaria and Ph. eustoma, and forms a strongly supported clade with Ph. thysanolaenicola and Ph. oryzae (CBS 110110) (Fig. 3). However, Ph. chiangraina morphologically differs from Ph. thysanolaenicola and can be separated from the epitype of Ph. oryzae due to its smoothwalled ascospores with a distinct sheath and based on phylogenetic evidence (Fig 3).

Wikee (RP0067), MFLU11-0187, living culture = MFLUCC 11-0151. Notes: Phaeosphaeria species (MFLUCC 11-0133 and MFLUCC 11-0151) were isolated from necrotic leaf spots symptoms on Calathea sp. and Cordyline sp. from Thailand. These two collections have similar morphological characters with Phaeosphaeria musae and Ph. panici (P. Syd.) Shoemaker & C.E. Babc. However they differ from Phaeosphaeria panici in having larger ascomata and asci and being associated with a different host. Phaeosphaeria panici lacks molecular data to confirm a natural placement, while these isolates form a strongly-supported clade (70 % MP) with Ph. musae in the Phaeosphaeria sensu stricto clade. Based on the ITS and TEF1 pair wise comparisons and multigene phylogenetic evidence, it appears that these isolates are conspecific with Phaeosphaeria musae. Thus, they are identified as Phaeosphaeria musae, and the species is reported associated with leaf spot disease on Calathea sp. and Cordyline sp. from Thailand. Pathogenicity was not confirmed.

Material examined: THAILAND, Chiang Rai Province, Phan District, Pukang Waterfall, on living leaves of Thysanolaena maxima Kuntze (Poaceae), 22 May 2010, R. Phookamsak (RP0036) (MFLU 11-0157, holotype), ex-type living culture=MFLUCC 10-0563=MUCL. Notes: Phaeosphaeria thysanolaenicola is most similar to Ph. oryzae as they share a similar ascoma, asci and ascospore size range. However, they differ in habitat and host preferences, as Ph. thysanolaenicola is associated with other fungi on leaf spots of Thysanolaena maxima. Whereas Ph. oryzae was found as a saprobe on Oryzae sativa. The ITS pair wise comparison shows that they differ in eight base positions. Phylogenetic analysis performed with a combination of ITS, LSU, RPB2 and TEF1 genes shows that Ph. thysanolaenicola forms a clade with Ph. chiangraina. Phaeosphaeria thysanolaenicola differs from Ph. chiangraina in its smaller asci and ascospores, habitat, host occurrence and ascospore ornamentation. Phaeosphaeria thysanolaenicola has echinulate ascospores while Ph. chiangraina has smoothwalled ascospores. Fungal Diversity (2014) 68:159–238 209 Fig. 22 Phaeosphaeria thysanolaenicola (MFLU 11-0157, holotype). a Ascomata on host surface. b Section through ascoma. c Section through peridium. d Cellular pseudoparaphyses. e–h Asci. i–l Ascospores.

Saprobic or pathogenic on various monocotyledons. Sexual state: Ascomata scattered to clustered, immersed, visible as small, black spots on host surface, uni- to biloculate, globose to subglobose, glabrous, brown, ostiole central, penetrating through host surface. Peridium thin-walled, of equal thickness, composed of brown to dark brown, pseudoparenchymatous cells of textura angularis. Hamathecium composed of numerous, filiform, frequently anastomosing, broad cellular pseudoparaphyses, with distinct septa and constricted at the septa. Asci 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindric-clavate, subsessile to short pedicellate, apically rounded, with indistinct ocular chamber. Ascospores overlapping 1–3-seriate, phragmosporous, oblong to cylindrical, often with one enlarged cell, yellowish-brown to brown or reddish-brown, 3–5-transeptate, slightly curved, not constricted at the septa, walls smooth or rough, echinulate or verruculose, surrounded by mucilaginous sheath. Asexual state: see under Phaeostagonospora. Type species: Phaeosphaeriopsis glaucopunctata Phylogenetic study: Câmara et al. (2003); Schoch et al. (2009); Zhang et al. (2012); Quaedvlieg et al. (2013); Hyde et al. (2013), Thambugala et al. (2014). Notes: Phaeosphaeriopsis was introduced by Câmara et al. (2003) and typified by Ps. glaucopunctata to accommodate non congeneric species of Paraphaeosphaeria. Phaeosphaeriopsis 210 agavensis (A.W. Ramaley et al.) Câmara et al., Ps. amblyspora A.W. Ramaley, Ps. glaucopunctata (Grev.) Câmara et al., Ps. nolinae (A.W. Ramaley) Câmara et al., and Ps. obtusispora (Speg.) Câmara et al. were introduced in the genus based on morphological characters and phylogenetic analyses of Phaeosphaeriopsis glaucopunctata (CBS 653.86) (Câmara et al. 2003; Zhang et al. 2012; Thambugala et al. 2014). Farr et al. (2006) transferred Sphaeria phacidiomorpha to Phaeosphaeriopsis phacidiomorpha based on the type morphological characters and microsphaeropsis-like asexual state which was most similar to Phaeosphaeriopsis. However, Sphaeria phacidiomorpha differs from other Phaeosphaeriopsis species by its hyaline ascospores (Farr et al. 2006; Thambugala et al. 2014). Phaeosphaeriopsis phacidiomorpha is currently synonymized under the name Glomerella phacidiomorpha (Ces.) Petr. (Index Fungorum 2014; Thambugala et al. 2014). Phaeosphaeriopsis musae was introduced and accommodated in Phaeosphaeriaceae by Arzanlou and Crous (2006) and is a pathogen causing leaf spots on banana. Subsequent phylogenetic analysis indicated that Ps. musae clusters with Phaeosphaeria oryzae and separate to Phaeosphaeriopsis glaucopunctata (Zhang et al. 2012; Hyde et al. 2013; Phookamsak et al. 2013, 2014). Thus, Thambugala et al. (2014) synonymized Phaeosphaeriopsis musae under the older name Phaeosphaeria musae Sawada (1959) based on morphological characters and phylogenetic evidence. Additionally, Thambugala et al. (2014) epitypified Phaeosphaeriopsis glaucopunctata and described the new species Phaeosphaeriopsis triseptata K.M. Thambugala & K.D. Hyde with sexual and asexual morphs. Six species are listed in Index Fungorum (2014) and 59 sequences are available in GenBank. Molecular analysis confirms the placement of Phaeosphaeriopsis in Phaeosphaeriaceae (Zhang et al. 2012; Hyde et al. 2013; Quaedvlieg et al. 2013; Thambugala et al. 2014; Wijayawardene et al. 2014b). A collection of Phaeosphaeriopsis was made which causes leaf spots on leaves of Dracaena lourieri Gagnep in Thailand. Based on morphological characters and multigene phylogenetic analysis, a new species, Phaeosphaeriopsis dracaenicola, is introduced to accommodate this taxon in the present paper. Phaeosphaeriopsis glaucopunctata (Grev.) M.P.S. Câmara et al. [as ‘glauco-punctata’], in Câmara et al., Mycol.

Material examined: THAILAND, Chiang Rai Province, Muang District, Nang Lae Village, on living leaves of Dracaena lourieri Gagnep (Asparagaceae), 21 September 2010, S. Wikee, RP0073 (MFLU11-0193, holotype), extype living culture = MFLUCC 11-0157 = MUCL; ibid. Chiang Mai Province, Mae Wang District, Doi Inthanon, Royal Project, on living Dracaena loureiri, 16 November 2010, R. Phookamsak, RP0109 (MFLU 11-0229, paratype), ex-paratype living culture=MFLUCC 11-0193=MUCL. Notes: Phaeosphaeriopsis dracaenicola is typical of Phaeosphaeriopsis, due to the asexual state, habitat and host preferences and it shares similar morphological characters to Ps. agavensis, Ps. nolinae, and Ps. obtusispora in its brown, 5-septate ascospores. However, these can be differentiated by size of ascomata, asci and ascospores. Phaeosphaeriopsis dracaenicola has smaller ascospores, asci and ascomata than the other species in the genus, and ascospores are smoothwalled, while the other species have rough-walled, echinulate or punctuate ascospore ornamentation. In addition, Phaeosphaeriopsis dracaenicola was found associated with lesions on leaves of Dracaena, while the other species are saprobic on Agave and Nolina (Ramaley 1997; Câmara et al. 2001, 2003; Thambugala et al. 2014). Pathogenicity was not confirmed. Phaeosphaeriopsis dracaenicola formed an 213 asexual state similar to Ps. agavensis and Ps. obtusispora, but differed from Ps. nolinae as conidia are globose. Multigene phylogenetic analysis shows that Ps. dracaenicola formed a robust clade (100 % ML/ 100 % MP/ 1.00 PP) at the basal of Phaeosphaeriopsis species in Phaeosphaeriaceae. Phaeostagonospora A.W. Ramaley, Mycotaxon 61: 351 (1997), Faces of Fungi number: FoF00267. Saprobic on Nolina erumpens (Torr.) S. Wats. Sexual state: reported as Phaeosphaeriopsis. Asexual state: Conidiomata pycnidial, scattered, solitary, immersed or subepidermal, uniloculate, elongated to globose, flattened at the apex against the host epidermis, with small papilla penetrating the host epidermis. Conidiomata walls thick, composed of 3– 6 layers of brown-walled cells, with 1–2 hyaline interior layers, abundant light brown hyphae from walls associated with host substrate. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, discrete, doliiform, ampulliform or irregular in shape, hyaline, smooth-walled, lining inner cavity of conidiomata. Macroconidia phragmosporous, ellipsoidal to cylindrical, with rounded ends, brown, 1–3-septate, rough-walled, foveolate. Microconidia globose or ellipsoidal, hyaline, smooth-walled, forming on the conidiomatal wall near the ostiole (from Ramaley 1997). Type species: Phaeostagonospora nolinae A.W. Ramaley, Mycotaxon 61: 351 (1997). Phylogenetic study: None Notes: When Câmara et al. (2003) introduced the genus Phaeosphaeriopsis; they also mentioned the asexual state of this genus as Phaeostagonospora. This was based on cooccurrence on the host (Ramaley 1997; Câmara et al. 2001). The sexual and asexual connection was, however, not equivocally confirmed. Thambugala et al. (2014) epitypified Phaeosphaeriopsis glaucopunctata and described the asexual state from cultures. The asexual state of P. glaucopunctata differs from Phaeostagonospora nolinae as conidia are aseptate, smaller, and verruculose, while Phaeostagonospora nolinae has septate conidia and it produces larger microconidia (Ramaley 1997; Thambugala et al. 2014). Therefore the link between Phaeostagonospora and Phaeosphaeriopsis requires confirmation. Sclerostagonospora Höhn., Hedwigia 59: 252 (1917), Faces of Fungi number: FoF00268. Pathogenic or saprobic on various monocotyledons and dicotyledons. Sexual state: phaeosphaeria-like. Asexual state: Conidiomata pycnidial, scattered, solitary, immersed, uniloculate, globose, glabrous, dark brown to black, ostiole central, with papilla. Conidiomata walls thin, composed of thick-walled cells, arranged in textura angularis, dark brown, inner layers lined with a hyaline cells bearing conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, discrete, determinate, ampulliform to irregular, hyaline, smooth-walled, lining inner 214 cavity of conidiomata. Conidia phragmosporous, cylindrical to tapered slightly to the base, obtuse at the apex, with truncate base, pale brown, septate, slightly constricted at the septa, thin and rough-walled, verruculose (from Quaedvlieg et al. 2013). Type species: Sclerostagonospora heraclei (Sacc.) Höhn., Hedwigia 59: 252. 1917. Phylogenetic study: Crous et al. (2008), Quaedvlieg et al. (2013). Notes: Sclerostagonospora was introduced by Höhnel (1917) and typified by S. heraclei (Sacc.) Höhn. The genus is similar to Stagonospora but differs in having pigmented conidia (Sutton 1980; Quaedvlieg et al. 2013). Crous et al. (2008) included Sclerostagonospora species in their phylogenetic analysis and Sclerostagonospora form a clade with other Phaeosphaeria species. Quaedvlieg et al. (2013) introduced a new species, S. phragmiticola from Phragmites australis (Poaceae) and confirmed that Sclerostagonospora is asexual genus belongs to Phaeosphaeriaceae based on their phylogenetic investigation. Quaedvlieg et al. (2013) mentioned that the sexual state of this genus is phaeosphaeria-like. In this study, two species of Sclerostagonospora form a distinct clade in our multigene phylogenetic analyses (Fig. 2). Sclerostagonospora phragmiticola (CBS 338.86) groups with Phaeosphaeria phragmiticola (CBS 459.84) in clade E and other genera in Phaeosphaeriaceae with weak bootstrap support. Whereas Sclerostagonospora cycadis (CBS 123538) clusters with Parastagonospora in clade H (Fig. 2). However, Sclerostagonospora is not represented by their type species. This genus needs better populating as it is presently not well-resolved. Scolecosporiella Petr., Annls mycol. 19(1/2): 30 (1921), Faces of Fungi number: FoF00269. Saprobic or pathogenic on various host plants. Sexual state: reported as Ophiosphaerella and Phaeosphaeria. Asexual state: Conidiomata stromatic, pycnidial, amphigenous, scattered to gregarious, immersed to subepidermal, uniloculate, glabrous, depressed-globose to globose or ovoid, pale brown to brown, ostiole central, circular, nonpapillate, with dark tendrils of conidia extruding through ostiole. Conidiomata walls thin, composed of thin-walled, subhyaline to pale brown cells, arranged in textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, annellidic, discrete, ampulliform, globose or irregular, hyaline, smooth-walled. Conidia phragmosporous, fusiform, with acute apex and a truncate base, subhyaline to pale brown, multi-septate, constricted at the septa, thick and smooth-walled, apical cell attenuated into a short, beak-like, appendage (from Nag Raj 1989). Type species: Scolecosporiella typhae (Oudem.) Petr., Annls mycol. 19(1/2): 31 (1921). ≡ Hendersonia typhae Oudem., Ned. kruidk. Archf, 2 sér. 1: 255 (1873) Phylogenetic study: None Fungal Diversity (2014) 68:159–238 Notes: Scolecosporiella was introduced by Petrak (1921) with S. typhae (Oudemans) Petr. as the type species. The genus was treated by Sutton (1968, 1980) and Sutton and Alcorn (1974) with five species being accommodated. Nag Raj (1989) re-examined the type species of Scolecosporiella, S. typhae and described the morphological characters in detail. Nag Raj (1989) distinguished Urohendersoniella mastigospora Petr. from Scolecosporiella typhae and reinstated the genus Urohendersoniella as this monospecific genus had been synonymized as Scolecosporiella mastigospora (Petr.) B. Sutton in Sutton (1980). Additionally, a new genus Orphanocoela was established to accommodate noncongeneric species of Scolecosporiella (Nag Raj 1989). Six species are listed in Index Fungorum (2014). Scolecosporiella has been reported as the asexual state of Ophiosphaerella herpotricha (Farr et al. 1989; Câmara et al. 2000; Zhang et al. 2012). However, there are no phylogenic evidence to confirm the connection between the sexual and asexual state, thus the generic connection is still questionable. Scolicosporium Lib. ex Roum., Fungi Selecti Galliaei Exs.: no. 676 (1880) Type species: Scolicosporium fagi Lib. ex Roum., in Roumeguère, Revue mycol., Toulouse 2: 22, 676 (1880) Phylogenetic study: Wijayawardene et al. (2013a) Notes: Scolicosporium Lib. ex Roum. was introduced by Roumeguère (1880) and typified by S. fagi Lib. ex Roum. Sutton (1980) treated Scolicosporium fagi, the type species of Scolicosporium as a synonym of S. macrosporium (Berk.) B. Sutton and designated S. macrosporium as the type species of Scolicosporium. However, Scolicosporium fagi is currently reported as the type species in Index Fungorum (2014). Scolicosporium was treated as a hyphomycete by Spooner and Kirk (1982) and Seifert et al. (2011). However, Treigiene and Mel’nik (2002) introduced S. minkeviciusii Treigiene as coelomycete, while Wijayawardene et al. (2013a) confirmed the species as a coelomycete. Furthermore, Wijayawardene et al. (2013a) showed that S. minkeviciusii belongs to Phaeosphaeriaceae, Pleosporales, in their molecular analyses. However, the genus was not represented by the type species, hence further collections of the type species of Scolicosporium, S. fagi are essential to confirm the familial placement of Scolicosporium sensu stricto. Below we only discuss S. minkeviciusii. Scolicosporium minkeviciusii Treigiene., in Treigiene.& Mel’nik, Mikol. Fitopatol. 36(6): 45 (2002), Faces of Fungi number: FoF00270. Saprobic on bark of Quercus pubescens Willd. and Q. robur L. Sexual state: Unknown. Asexual state: Conidiomata 100–120μm high, 120–180μm diam., pycnidial, solitary to gregarious, uniloculate, elongate-globose, dark brown.

Conidiomata walls comprising 3–4 layers, outer layers 8–10μm wide, dark Fungal Diversity (2014) 68:159–238 brown, cells of textura angularis, inner layers hyaline, 5– 40μm wide. Conidiophores 13–30×2–3μm, 1–2-septate, branched at the base, hyaline, cylindrical. Conidiogenous cells annellidic, hyaline, cylindrical. Conidia 60–65×7–9μm (x = 62.2×7.7μm, n=20), phragmosporous, curved to sigmoid, pale to moderately dark brown, with hyaline end cells, 6–7-transverse eusepta, smooth-walled, tapered to the obtuse apex, base truncate (Wijayawardene et al. 2013a). Septoriella Oudem., Ned. kruidk. Archf, 2 sér. 5: 52 (1889) Type species: Septoriella phragmitis Oudem. [as ‘phragmitidis’], Ned. kruidk. Archf, 2 sér. 5: 54 (1889) Phylogenetic study: Crous et al. (2014) Notes: Septoriella was introduced by Oudemans (1889) with the generic type Septoriella phragmitis. Crous et al. (2014) introduced a new species Septoriella oudemansii based on a megablast nucleotide search in GenBank. The species was similar to Phaeosphaeria caricis, Ph. ammophilae and Ophiosphaerella herpotricha (Crous et al. 2014). The taxon clusters with the asexual species, Wojnowicia hirta and Amarenomyces ammophilae in Phaeosphaeriaceae in LSU gene phylogenetic analysis (data is not shown). However, the type species of Septoriella is not represented in GenBank. Thus, we tentatively include Septoriella in Phaeosphaeriaceae. Below we only discuss S. oudemansii. Septoriella oudemansii Crous & Quaedvl., Persoonia, Mol. Phyl. Evol. Fungi 32: 281 (2014), Faces of Fungi number: FoF000304. Saprobic on Phragmites australis (Cav.) Trin. ex Steud (Poaceae). Sexual state: Unknown. Asexual state: Conidiomata up to 250μm diam., pycnidial, solitary, immersed, uniloculate, globose, glabrous, brown, ostiole central, with a brown, oozing, conidial cirrhus. Conidiomata walls composed of 3–4 layers, brown, arranged in textura angularis. C o n i d i o p h o re s r e d u c e d t o c o n i d i o g e n o u s c e l l s . Conidiogenous cells 5–11×4–5μm, ampulliform, hyaline, smooth-walled, apex with minute periclinal thickening or percurrent proliferation, lining the inner cavity. Conidia (17–)23–32(−35)×(3.5–)4(−6), solitary, subcylindrical, with obtuse ends, slightly wider in the middle, yellowish-brown, 3(−5)-septate, becoming slightly constricted at the septa with age, smooth-walled, with guttules and flared mucoid appendages at the ends (from Crous et al. 2014). Setomelanomma M. Morelet, Bull. Soc. Sci. nat. Arch. Toulon et du Var 227: 15 (1980), Faces of Fungi number: FoF00271. Type species: Setomelanomma holmii. Phylogenetic study: Rossman et al. (2002), Schoch et al. (2009), Zhang et al. (2009, 2012), Hyde et al. (2013), Wijayawardene et al. (2014b). Notes: Setomelanomma was introduced by Morelet (1980) as typified by S. holmii to accommodate the monotypic genus from France associated with branches of Picea. Morelet (1980) however, did not illustrate the fungus and did not 215 provide a detailed description (Rossman et al. 2002; Zhang et al. 2012). Rossman et al. (2002) re-circumscribed the type species and compared the morphological characters with North American collections. Detailed descriptions using morphology and molecular phylogeny were given by Zhang et al. (2012). Rossman et al. (2002) placed the genus in Phaeosphaeriaceae due to the morphology and phylogenetic data and this was later accepted by various authors (Kodsueb et al. 2006, 2007; Schoch et al. 2009; Zhang et al. 2009, 2012; Hyde et al. 2013). The genus is morphologically typical of Phaeosphaeriaceae as the ascomata are relatively small, the peridium is thin-walled comprising pseudoparenchymatous cells, pseudoparaphyses are cellular; and brown to yellowish-brown, and ascospores are phragmosporous (Rossman et al. 2002; Zhang et al. 2012). Setomelanomma however, differs from other genera in Phaeosphaeriaceae by its setose ascomata. No asexual state is known for the genus. There are two species, S. holmii and S. prolata K.J. Leonard & Suggs listed in Index Fungorum (2014) Based on the multigene phylogenetic analyses (Figs. 1 and 2), Setomelanomma forms a strongly supported clade with the asexual species, Xenoseptoria neosaccardoi and Paraphoma radicina (CBS 111.79) in Phaeosphaeriaceae and these genera may be the asexual morphs of Setomelanomma. Setomelanomma holmii M. Morelet, Bull. Soc. Sci. nat. Arch. Toulon et du Var 36(no. 227): 15 (1980), Faces of Fungi number: FoF00272, Fig. 25. Pathogenic on branches of Picea. Sexual state: Ascomata 100–150μm high, 140–175μm diam., scattered, gregarious semi-immersed to erumpent through host tissue, becoming superficial, visible as abundant, small black dots on the host surface, uniloculate, globose to subglobose, covered by setae, dark brown to black, with central ostiole. Peridium 12.5– 26μm wide, thin-walled, of equal thickness, composed of 5– 7 layers of black, broadly pseudoparenchymatous cells, arranged in a textura angularis to textura globulosa. Hamathecium composed of numerous, 1.5–3μm wide, filamentous, frequently anastomosing, broad cellular pseudoparaphyses, with distinct septa, embedded in mucilaginous matrix. Asci (67–)68–77(−85)×(13–)15–17(−20) μm (x = 75.2×15.2μm, n=20), 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindric-clavate, subsessile to short pedicellate, apically rounded with well-developed ocular chamber. Ascospores (18–)21–23(−24)×(6–)7–9(−11) μm (x = 21.3 × 8.2 μm, n = 20), overlapping 1–2-seriate, phragmosporous, ellipsoidal to broadly fusiform, initially hyaline to pale yellowish, becoming light brown to brown or yellowish-brown at maturity, initially forming one median septum, becoming 3-septate at maturity, slightly curved, often constricted at the median septum, smooth and thick-walled.

Pathogenic or saprobic on various hosts (Alliaceae, Asteraceae and Poaceae). Sexual state: Ascomata, scattered, gregarious, immersed, visible as raised, minute black dots on host surface, uniloculate, globose to subglobose, glabrous, brown to dark brown, ostiole central, with minute papilla. Peridium thin-walled, of equal thickness, composed of pseudoparenchymatous cells, arranged in flattened textura angularis to textura prismatica. Hamathecium composed of numerous, filiform, broad cellular, pseudoparaphyses, with distinct septa, anastomosing at the apex. Asci 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, short pedicellate, apically rounded, with well-developed narrowly ocular chamber. Ascospores overlapping 2-seriate, phragmosporous, cylindrical to cylindric-clavate, hyaline, 3-septate, usually enlarge at the second cell from apex, smooth-walled with large guttules. Asexual state: produced on rice straw and bamboo pieces on water agar after four weeks. Conidiomata scattered to clustered, gregarious, superficial, globose to subglobose, setose, and sometimes glabrous when mature, initially light brown, becoming brown to dark brown. Conidiomata walls thin, composed of light brown to brown pseudoparenchymatous cells, arranged in a textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, determinate, discrete, unbranched, oblong to cylindrical, or ampulliform, hyaline, slightly curved, aseptate, lining the inner cavity of conidioma. Conidia amerosporous, oblong to ellipsoidal, rarely irregular, with rounded or obtuse ends, hyaline, aseptate, smooth-walled (from De Gruyter et al. 2010; Phookamsak et al. 2014).

Hansen, Phytopathology 19(8): 699 (1929) Phylogenetic study: De Gruyter et al. (2010), Quaedvlieg et al. (2013), Phookamsak et al. (2014) Notes: Setophoma was introduced by De Gruyter et al. (2010) to accommodate phoma-like species and is typified by S. terrestris. Two species, S. sacchari (Bitanc.) Gruyter et al. and S. terrestris (H.N. Hansen) Gruyter were accommodated in this genus. Quaedvlieg et al. (2013) introduced a new species Setophoma chromolaenae Quaedvlieg et al. on leaves of Chromolaena odorata from Brazil. No sexual state was reported. Phookamsak et al. (2014) reported the sexual state of Setophoma based on asexual-sexual connection of S. sacchari and phylogenetic data. The sexual state of Setophoma is 217 similar to Phaeosphaeria species, but differs in ascospore colour and asexual state (Phookamsak et al. 2014). Setophoma chromolaenae, S. sacchari, S. terrestris and S. vernoniae Crous & Alfenas are presently accommodated in the genus (Index Fungorum 2014; Crous et al. 2014; Phookamsak et al. 2014). Based on multigene phylogenetic analysis, we accept Setophoma in Phaeosphaeriaceae which forms a single clade at basal of the family (Fig. 2). Tiarospora Sacc. & Marchal, Revue mycol., Toulouse 7(no. 26): 148 (1885), Faces of Fungi number: FoF00274. Saprobic or pathogenic on Ammophila Host, Deschampsia P. Beauv., Elymus L. (Poaceae) and Dryas grandis Jurtzev (Rosaceae). Sexual state: Unknown. Asexual state: Conidiomata scattered, gregarious, immersed to semi-immersed, uniloculate, globose, glabrous, brown, ostiole central, with short papilla. Conidiomata walls thick, composed on several layers, outer layers comprising thick-walled dark brown, flattened cells of textura angularis, inner layers comprising thin-walled paler cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, sympodial, discrete, doliiform, cylindrical or lageniform, hyaline, smooth-walled. Conidia didymosporous, broadly ellipsoid, with obtuse to flattened ends, hyaline to pale brown, 1-septate, continuous, thick and smooth-walled, with guttules or irregular or cap-like gelatinous appendage (from Sutton 1980). Type species: Tiarospora westendorpii Sacc. & Marchal, Revue mycol., Toulouse 7(no. 26): 148 (1885). Phylogenetic study: None Notes: Tiarospora was introduced by Saccardo and Marchal (1885) and is typified by T. westendorpii Sacc. & Marchal. Four species were accommodated under Tiarospora; T. deschampsiae Krusch., T. perforans (Sacc.) Höhn., T. pirozynskii Chleb. and T. westendorpii Sacc. & Marchal. However, Tiarospora perforans was transferred to Montagnulaceae by Aptroot (2006). Tiarospora is similar to Tiarosporella Höhn.; however, they differ in the morphology of their conidia. Tiarospora has 1-septate conidia, while Tiarosporella has aseptate conidia (Abbas et al. 2012). Tiarospora was described in Sutton (1980); however, no family placement was given for the genus. Kirk et al. (2001, 2008) treated the genus under Phaeosphaeriaceae but did not mention any literature to confirm this and this was accepted by Wijayawardene et al. (2012). Oertel (2011) however, mentioned that the type species of Tiarospora, T. westendorpii is a synanamoph of Amarenographium metableticum, which is the asexual state of Amarenomyces, also in Phaeosphaeriaceae. Therefore the current placement of this genus is somewhat unclear. The genus is relatively poorly known, lacks molecular data and no sexual state is known. We tentatively place Tiarospora in Phaeosphaeriaceae until molecular data resolves this issue. Vrystaatia Quaedvlieg et al. Stud.

Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, annellidic, discrete, globose to ampulliform, hyaline, smooth-walled, with prominent periclinal thickening, or proliferating several times percurrently near apex, producing macro- and microconidia. Macroconidia scolecosporous, subcylindrical to narrowly obclavate, apex obtuse to subobtuse, with truncate base, hyaline, (1–)3-septate, smooth-walled, with guttules, widest at the basal septum. Microconidia pear-shaped to globose or ellipsoidal, apex obtuse, with truncate base, hyaline, aseptate, smooth-walled (from Quaedvlieg et al. 2013). Type species: Vrystaatia aloeicola Quaedvlieg et al. Stud. Mycol. 75: 372 (2013) Phylogenetic study: Quaedvlieg et al. (2013). Notes: Vrystaatia was introduced by Quaedvlieg et al. (2013) to accommodate a non-congeneric species of Septoria sensu stricto and typified by V. aloeicola. Vrystaatia is similar to Septoria sensu stricto, but differs in Fig. 27 Vrystaatia aloeicola, redrawn from Quaedvlieg et al. (2013). Scale bars=10μm 219 conidiogenous cells morphology and forms macro- and microconidia in culture, which was not typical of Septoria (Quaedvlieg et al. 2013). Based on multigene phylogenetic analysis (Fig. 2), Vrystaatia forms a single clade at the basal of Paraphoma, Setomelanomma and Xenoseptoria clade. Thus we accept Vrystaatia for which no sexual state is known in Phaeosphaeriaceae. Wojnowicia Sacc., Syll. fung. (Abellini) 10: 328 (1892), Faces of Fungi number: FoF00276. Pathogenic on monocotyledonous or dicotyledonous hosts. Sexual state: Unknown. Asexual state: Conidiomata pycnidial, scattered, solitary, immersed to superficial on host tissue, globose, glabrous or setose, dark brown, ostiole central, with minute papillate or pore-like opening. Conidiomata walls thick, composed of pseudoparenchymatous cells, outer layers thick-walled, arranged in textura angularis, dark brown, inner layers thin-walled, hyaline, thinner towards inner conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, discrete, determine, doliiform to ampulliform, hyaline, smooth-walled, with minute collarette and channel, lining inner cavity of conidiomata. Conidia phragmosporous, fusiform to cylindrical, with obtuse ends, pale brown to brown, continuous, septate, straight to curved, thin and smooth-walled, guttulate. Type species: Wojnowicia hirta (J. Schröt.) Sacc., in Saccardo & Sydow, Syll. fung. (Abellini) 14(2): 960 (1899). Phylogenetic study: De Gruyter et al. (2009), Wijayawardene et al. (2013b). Notes: Wojnowicia was introduced by Saccardo (1892) and is typified by W. hirta. The genus was discussed by Sutton (1975, 1980) who accepted two species, W. hirta and 220 W. ephedrae Hollós. Sutton (1980) treated W. tenella Pat. and W. graminis (McAlpine) Sacc. & D. Sacc as synonyms of W. hirta. Farr and Bills (1995) named a collection from Juniperus deppeana Steud. and Pinus edulis Engelm. As W. colluvium D.F. Farr & Bills. Eleven species are listed in Index Fungorum (2014). Molecular data is only available for two species in GenBank. De Gruter et al. (2009) included two strains of Wojnowicia hirta in their analysis and showed that W. hirta belongs to Phaeosphaeriaceae. Wijayawardene et al. (2013b) introduced a new species, W. viburni Wijayaw. et al. on leaves of Viburnum utile Hemsl. ex Forb. & Hemsl. from China and confirmed that Wojnowicia belongs in Phaeosphaeriaceae. They also suggested that Wojnowicia should be the asexual state of Ophiosphaerella based on phylogenetic evidence (Wijayawardene et al. 2013b). However, Wijayawardene et al. (2013b) and De Gruyter et al. (2009) did not include many isolates of Phaeosphaeriaceae in their analysis. In this study with several sexual and asexual genera, the multigene phylogenetic analysis (Fig. 2) indicates that Wojnowicia hirta (CBS 160.73, CBS 295.69) clusters with Amarenomyces, Ophiosphaerella herpotricha (CBS 620.86) and other Phaeosphaeria sensu lato species while W. viburni forms a single clade at the base of Neostagonospora. Therefore the findings of Wijayawardene et al. (2013b) and De Gruyter et al. (2009) that Wojnowicia may be an asexual state of Ophiosphaerella is questionable, while Ophiosphaerella is obviously polyphyletic and requires further work. Xenoseptoria Quaedvlieg et al. Stud. Mycol. 75: 371 (2013), Faces of Fungi number: FoF00277. Pathogenic on Lysimachia vulgaris var. davurica (Ledeb.) R. Knuth (Primulaceae). Sexual state: unknown but possibly Setomelanomma. Asexual state: Conidiomata pycnidial, scattered, solitary, immersed to erumpent, uniloculate, globose, glabrous, brown, ostiole developing 1–3 papilla or necks, exuding a pink to orange conidial mass. Conidiomata walls thin, composed of 4–8 layers of brown cells, arranged in textura angularis. Conidiophores reduced to conidiogenous cells, hyaline, septate, branched, smoothwalled. Conidiogenous cells enteroblastic, mono- to polyphialidic, with prominent periclinal thickening, or percurrent proliferation, discrete or integrated, ampulliform to doliiform or subcylindrical, hyaline, smooth-walled. Conidia scolecosporous, cylindrical to obclavate, tapering to subobtuse apex, with obtuse base, straight to irregular curved, hyaline, septate, smooth-walled, with guttules (from Quaedvlieg et al. 2013) Type species: Xenoseptoria neosaccardoi Quaedvlieg et al., Stud. Mycol. 75: 371 (2013). Phylogenetic study: Quaedvlieg et al. (2013) Notes: Xenoseptoria was introduced by Quaedvlieg et al. (2013) and was typified by X. neosaccardoi. The genus was introduced to accommodate a single species associated with Fungal Diversity (2014) 68:159–238 leaf spot disease of Lysimachia vulgaris var. davurica (Primulaceae). The genus can be distinguished from Septoria sensu stricto as Xenoseptoria has multi-papillate conidiomata and mono- to polyphialidic conidiogenous cells (Quaedvlieg et al. 2013). In multigene phylogenetic analysis, Xenoseptoria clusters with the sexual genus Setomelanomma and the asexual genus Paraphoma with strong support (91 % ML, 1.00 PP). The genus is closely related to Setomelanomma. These genera may need placing in synonymy with Setomelanomma, but it would be unwise to do so until the tree becomes better populated. Genera transferred to other families Botryosphaeriaceae Recent accounts of Botryosphaeriaceae include those of Liu et al. (2012) and Hyde et al.

Sexual state: Ascostromata scattered, solitary to gregarious, erumpent through host epidermis, visible as slightly raised, black lines or black spots on the host surface. Locules clustered in pseudostroma, uni to bi-loculate, globose to subglobose, glabrous, black, ostiole in centre of each locule, with minute papilla. Peridium thick-walled, composed of thickened, black, scleroplectenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, broad cellular pseudoparaphyses, anastomosing at the apex. Asci 8-spored, bitunicate, cylindrical to cylindric-clavate, subsessile to short pedicellate, apically rounded, with well-developed ocular chamber. Ascospores overlapping 1–2-seriate, 2-celled, oblong to cylindrical, narrow towards lower end cell, hyaline, septate, smoothwalled, cytoplasm stains blue in cotton blue reagent, the large guttules in the upper part of the upper cell not staining. Asexual state: Unknown. Type species: Metameris japonica Phylogenetic study: None. Notes: Metameris was established to accommodate Monographus japonicus Syd. by Theissen and Sydow (1915). Metameris forms linear pseudostromata, and has hyaline, 1-septate ascospores and Clements and Shear (1931) treated the genus under Dothideaceae (Zhang et al. 2012). Müller and von Arx (1962) treated Metameris as a synonym of Scirrhia and placed the genus in Mycosphaerellaceae (Crous et al. 2011). Later, von Arx and Müller (1975) assigned the genus to Pleosporaceae and did not accept that Metameris was synonymous with Scirrhia (Crous et al. 2011; Zhang et al. 2012). Recently, Metameris was accommodated in Phaeosphaeriaceae due to its small ascomata, Fungal Diversity (2014) 68:159–238 broad cylindrical to obclavate asci with a knob-like pedicel and monocotyledons host preferences (Eriksson 2006; Lumbsch and Huhndorf 2007, 2010; Crous et al. 2011; Zhang et al. 2012; Hyde et al. 2013). However, the genus lacks molecular data to confirm its familial placement (Crous et al. 2011; Zhang et al. 2012). There are five epithets listed for Metameris in Index Fungorum (2014); however, three species are synonymized under Scirrhia. In this study, we exclude Metameris from Phaeosphaeriaceae. The large, elongated pseudostromata, with a peridium of thickened scleroplectenchymatous cells, broad, or irregularly cellular pseudoparaphyses, ascus morphology and didymosporous ascospores are characters typical of genera in Botryosphaeriaceae where it is tentatively referred. Leptoguignardia is probably most similar (Liu et al. 2012) and should be compared in future studies of fresh collections. Metameris japonica (Syd.& P. Syd.)

Peridium 12–40μm wide, thin-walled, of unequal thickness, thickened at apex at sides, composed of 3 or more layers of brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis, outer layers comprising 2–5 layers of thickened cells, brown to dark brown, inner layers comprising several layers of flattened cells, hyaline to pale brown.

Mixtura is similar to Mycosphaerella and Phaeosphaeria species in causing a leaf spot disease on monocotyledons, Fungal Diversity (2014) 68:159–238 223 Fig. 29 Mixtura saginata (S-F8935, lectotype). a Herbarium label and specimens. b Ascomata on leaf lesion. c Section through ascoma d Section through peridium. e Pseudoparaphyses stained in cotton blue reagent. f Immature ascus. g–i Asci. j Ocular chamber of asci stained in cotton blue reagent. k Immature ascospore stained in cotton blue reagent. l–m Mature ascospores. Scale bars: c=100μm, d–m=20μm but differs from Mycosphaerella species in its centrum type (Eriksson and Yue 1990). Mixtura differs from Trematosphaeria due to its fusiform, olive brown ascospores and the genus differs from Wettsteinina as its rather thick-walled peridium and ellipsoidal asci (Eriksson and Yue 1990). Eriksson and Yue (1990) treated the genus in Phaeosphaeriaceae based on the peridium structure. However, Zhang et al. (2012) disagreed with Eriksson and Yue (1990) and placed the genus in Teratosphaeriaceae with Mixtura having relatively similar morphology to the type species of Teratosphaeria. 224 Mixtura is similar to other genera in Phaeosphaeriaceae such as Hadrospora and Loratospora in its saccate asci and large ascospores in Hadrospora. However, these genera differ in their centrum type. Mixtura forms dense, thick, cellular pseudoparaphyses, while Hadrospora forms trabeculate pseudoparaphyses, and pseudoparaphyses are lacking in Loratospora. Hadrospora is excluded as a member of Phaeosphaeriaceae in this study, but Loratospora is confirmed based on phylogenetic evidence. Mixtura is similar to Leptosphaerulina in habitat on host and asci. However, they differ in the ascospores and centrum type as Leptosphaerulina lacks pseudoparaphyses and has muriform ascospores. Mixtura has dense pseudoparaphyses and phragmosporous ascospores with distosepta. Therefore, we agree with Zhang et al. (2012) and exclude Mixtura from Phaeosphaeriaceae. The genus is tentatively placed in Didymellaceae. Didymosphaeriaceae For an account of this family see Ariyawansa et al. (2014b). Barria and Wilmia were transferred from Phaeosphaeriaceae to Didymosphaeriaceae in Ariyawansa et al. (2014b and are only briefly discussed here. Barria Z.Q. Yuan, Mycotaxon 51: 313 (1994), Faces of fungi number: FoF00031. Type species: Barria piceae Z.Q. Yuan, Mycotaxon 51: 314 (1994). Phylogenetic study: None. Notes: Barria is a monotypic genus introduced by Yuan (1994) based on Barria piceae. The genus was reported as pathogenic on needles of Picea schrenkiana Fisch. & C.A. Mey. Barria is excluded from Phaeosphaeriaceae in this study based on its morphology. Barria is associated with gymnosperms, asci are clavate and short pedicellate, and ascospores are didymosporous with thick walls. Whereas the generic type, Phaeosphaeria is associated mostly with angiosperms, asci are often broad cylindrical to cylindric-clavate and subsessile and ascospores are phragmosporous (Yuan 1994; Zhang et al. 2012; Hyde et al. 2013; Quaedvlieg et al. 2013). Additionally, most genera with confirmed phylogenetic placement in Phaeosphaeriaceae have phragmospores, scolecospores, or muriform ascospores, but there are no didymosporous taxa (Zhang et al. 2012; Hyde et al. 2013; Quaedvlieg et al. 2013). Barria is associated in the same host family as Setomelanomma which was confirmed as phaeosphaeriacous based on phylogenetic evidence. Barria has didymosporous ascospores, while Setomelanomma has phragmosporous ascospores. Most didymosporous genera in Phaeosphaeriaceae lack molecular phylogenetic data to confirm their current placements. Furthermore, Barria is more similar to genera in Didymosphaeriaceae rather than Phaeosphaeriaceae (Ariyawansa et al. 2014b), where is it Fungal Diversity (2014) 68:159–238 tentatively accommodated. Zhang et al. (2012) accepted Lautitia in Phaeosphaeriaceae; in contrast, all genera of marine and freshwater fungi (Carinispora, Isthmosporella and Ocala) were excluded from Phaeosphaeriaceae in Zhang et al. (2012). However, Lautitia differs from other genera in Phaeosphaeriaceae in having clavate asci with long pedicels and forming a pseudostromata with the peridium arranged in a textura porrecta. Other genera in Phaeosphaeriaceae mostly have cylindrical asci with subsessile to short pedicels and uniloculate ascomata with the peridium arranged in a textura angularis. Metameris forms large, elongated pseudostromata, with a thick-walled peridium of scleroplectenchymatous cells which is rarely found in other genera of Phaeosphaeriaceae. A new species of Letendraea (=Wilmia) was introduced based on phylogenetic evidence and belongs in Didymosphaeriaceae (see Ariyawansa et al. 2014b). Wilmia Dianese et al., Mycologia 93(5): 1014 (2001), Faces of fungi number: FoF00046. Type species: Wilmia brasiliensis Dianese et al., Mycologia 93(5): 1014 (2001). Phylogenetic study: Ariyawansa et al. (2014a). Notes: Wilmia was introduced by Dianese et al. (2001) to accommodate a monotypic genus, Wilmia brasiliensis that caused a leaf spot disease of Memora pedunculata (Vell.) Miers. in Brazil. Dianese et al. (2001) treated Wilmia in Phaeosphaeriaceae based on the morphological characters which fitted Barr’s concept (Barr 1987b, 1992a). Wilmia is similar to other genera in Phaeosphaeriaceae viz. Barria, Lautitia and Metameris in having didymosporous ascospores and a coelomycetous asexual morph (Dianese et al. 2001; Zhang et al. 2012). Zhang et al. (2012) tentatively placed Wilmia in Phaeosphaeriaceae as the genus is poorly known and lacks molecular data, although Zhang et al. (2012) mentioned that the genus should be accommodated in Leptosphaeriaceae based on its dicotyledonous host habit. A Dothideomycete species was collected from living and dead leaves of Cordyline sp. in Thailand. The species also caused leaf spot disease and had similar morphological characters to Wilmia brasiliensis. Ariyawansa et al. (2014b synonymized Wilmia under Letendraea based on morphology and phylogeny. Thus, the new species collected from Cordyline sp. was accommodated in Didymosphaeriaceae and named Letendraea cordylinicola Phookamsak et al. (Ariyawansa et al. 2014b).

Conidia oblong to ellipsoidal, with obtuse ends, brown, 1-septate, smooth-walled. Type species: Chaetoplea calvescens Phylogenetic study: None Notes: Chaetoplea was introduced by Clements and Shear (1931) to accommodate Dothideomycete species from woody substrates which included species transferred from Cucurbitaria, Leptosphaeria, Pleospora, Pyrenophora, Sphaeria and Teichospora (Shoemaker 1961; Wehmeyer 1961; von Arx and Müller 1975; Barr 1990b; Yuan and Barr 1994; Zhang et al. 2012). Barr (1987b, 1990a, b) treated Chaetoplea sensu lato in Phaeosphaeriaceae. The type specimen has not been recovered from any herbaria worldwide. Zhang et al. (2012) however observed the isotype which is a slide from the Farlow Herbarium (FH) and has only asci and ascospores. Zhang et al. (2012) mentioned that Chaetoplea may be heterogeneous in nature and occurs in a wide range of substrates such as herbaceous stalks, decorticated wood and periderm tissues. The asexual state of Chaetoplea (for Pyrenophora calvescens (Fr.) Sacc.) was first reported as Dendryphium comosum Walk. (Saccardo 1883). Later Webster and Lucas (1959) treated Microdiplodia henningsii Staritz. as the asexual state of Chaetoplea and this was accepted by Barr (1987b). However, Crous et al. (2006) treated Microdiplodia as an asexual state of Karstenula placed in the family Montagnulaceae. Ramaley (1995) reported Parahendersonia as the asexual state 225 of Chaetoplea dasylirionis being saprobic on Dasylirion (Agavaceae) and placed it in Leptosphaeriaceae. In this study, the asexual state of Chaetoplea was observed occurring on the same host as the lectotype. The asexual state of Chaetoplea forms oblong to ellipsoidal, brown, 1-septate, smooth-walled conidia which are microdiplodia-like. After examining Fries exsiccatus (Scler. Suecicae exsiccatus no. 401) in the US National Fungus Collections (BPI) it was determined that this should be designated as a lectotype in this study. Based on morphology, Chaetoplea is more similar to Leptosphaeriaceae than Phaeosphaeriaceae and this supports the current placement of Chaetoplea as listed in Index Fungorum (2014). Therefore Chaetoplea should currently be placed in Leptosphaeriaceae. Recollection, epitypification, and molecular data are needed to confirm the natural placement of Chaetoplea.

Ramaley 9237 (BPI 802381, holotype). Notes: The monotypic genus Pleoseptum was established by Ramaley and Barr (1995) to accommodate P. yuccaesedum. The genus was tentatively treated in Phaeosphaeriaceae based on its morphological characters and asexual morph (Lumbsch and Huhndorf 2010; Zhang et al. 2012; Hyde et al. 2013). Pleoseptum was compared with many genera such as Chaetoplea, Curreya, Heptameria and was considered most similar to Leptosphaeria based on its peridium structure (Ramaley and Barr 1995; Zhang et al. 2012). However, these genera differ in asexual states as in Pleoseptum conidia are dictyosporous, whereas in Leptosphaeria, they are stated to be amerosporous (De Gruyter et al. 2012; Hyde et al. 2013; Wijayawardene et al. 2014b). 228 Fungal Diversity (2014) 68:159–238 Fungal Diversity (2014) 68:159–238 31 Pleoseptum yuccaesedum (BPI 802381, holotype). a Herbarium label and specimens of Pleoseptum yuccaesedum. b Ascomata on host surface. c Section through ascoma. d Section through peridium. e Pseudoparaphyses. f–h Ascospores. i Ascospore stained in Indian ink. j–l Asci. m Section through conidiomata. n Pycnidial wall. o Conidiogenous cells. p–q Conidiogenous cells stained in congo red reagent (p= annellidic, q= sympodial proliferation). r–u Conidia.

Hyde fide Wijayawardene et al. 2014c), hence the status o f C a m a ro s p o r i u m y u c c a e s e d u m i s u n c e r t a i n . Camarosporium yuccaesedum is synonymized under Pleoseptum yuccaesedum herein. Trematosphaeriaceae Pleoseptum is a poorly known genus represented by only one species in Index Fungorum (2014) that lacks molecular sequence data in GenBank. The species has muriform spores which are similar to Dematiopleospora (Wanasinghe et al. 2014). Pleoseptum differs from Dematiopleospora by its peridium structure which is very thick, composed of heavily pigmented, thick-walled cells with ostiole and typical of Pleosporaceae in the former. Whereas the peridium is thinner, composed of lighter pigmented, thin-walled cells, with thick periphyses in the ostioles and typical of Phaeosphaeriaceae in Dematiopleospora. In Pleoseptum pseudoparaphyses are narrow, and additionally Pleoseptum forms a camarosporiumlike asexual state. Pleoseptum is therefore excluded for Phaeosphaeriaceae whose genera typically have a thinwalled peridium and broad cellular pseudoparaphyses and tentatively placed in Pleosporaceae. However, Pleoseptum yuccaesedum needs recollecting and subjected to molecular study to confirm this placement is correct. Camarosporium yuccaesedum was introduced as the asexual state of Pleoseptum yuccaesedum by Ramaley and Barr (1995) as both states co-inhabited the same host. Sexualasexual links were connected by culture comparisons with conidia produced in culture from a sexual state (Ramaley and Barr (1995). Camarosporium however, has also been reported as the asexual state in various genera in Botryosphaeriales and Cucurbitariaceae (Kirk et al. 2008; Zhang et al. 2012; Hyde et al. 2013). Recent molecular based research on Camarosporium by Crous et al. (2014) and Wijayawardene et al. (2014a, c, d) showed that Camarosporium sensu lato is highly polyphyletic in Pleosporales, while Camarosporium sensu stricto is well-established genus in Pleosporineae, Pleosporales (Wijayawardene et al. 2014a). Thus, Neocamarosporium Crous & M.J. Wingf. (Pleosporales incertae sedis fide Crous et al. 2014), Paracamarosporium Wijayaw. & K.D. Hyde (Montagnulaceae fide Wijayawardene et al. 2014a), Pseudocamarosporium Wijayaw. & K.D. Hyde (Montagnulaceae fide Wijayawardene et al. 2014c) and Eucamarosporium Wijayaw. & K.D. Hyde (Didymellaceae fide Wijayawardene et al. 2014d) have been introduced to accommodate several camarosporium-like taxa in Pleosporales. Significantly, Ramaley and Barr (1995) reported microconidia from Camarosporium yuccaesedum which have not been reported from Camarosporium sensu stricto (Crous et al. 2013; Wijayawardene et al. 2014a). However, Crous et al. (2013) For accounts of this family see Suetrong et al. (2011) and Hyde et al. (2013). Hadrospora Boise, Mem. N. Y. bot. Gdn 49: 310 (1989), Faces of Fungi number: FoF00285.

Type species: Hadrospora fallax Phylogenetic study: None Notes: Hadrospora was introduced to accommodate two species, originally placed in Trematosphaeria by Boise (1989), and was typified by Hadrospora fallax. Hadrospora has been reported from various hosts and habitats, both terrestrial and freshwater, from Belgium, China, Italy, Japan, Switzerland, and the United States (Boise 1989; Shearer and Crane 1971; Fisher and Webster 1992; Webster 1993; Tanaka and Harada 2003; Zhang et al. 2012). The genus was tentatively placed in Phaeosphaeriaceae due to its small ascomata, thin-walled peridium and narrow pseudoparaphyses (Boise 1989; Zhang et al. 2012). However, Hadrospora differs from other genera in Phaeosphaeriaceae by its large vermiform ascospores, ampulliform to saccate asci, trabeculate pseudoparaphyses and the hyphomycetous asexual morph with the type species which was treated as an amphibious species (Shearer 1993; Boise 1989; Tanaka and Harada 2003; Zhang et al. 2012). Other genera of Phaeosphaeriaceae are mostly terrestial and have cylindrical to cylindri-clavate asci with broad cellular pseudoparaphyses and produce coelomycetous asexual morphs. Hadrospora is similar to Mixtura in its large ascospores, and saccate asci; although Hardrospora has been reported as saprobic on various hosts, 230 while Mixtura was found as plant pathogen of bamboo. The second species, Hadrospora clarkii (Sivan.) Boise is listed as Trematosphaeria clarkii Sivan. in Index fungorum (2014). A zalerion-like asexual morph was reported for Hadrospora with conidia being produced on PDA after 4 months (Tanaka and Harada 2003). The genus is characterized by holoblastic, helicoid, multiseptate, brown to dark brown, smooth-walled conidia which are constricted at the septum (Tanaka and Harada 2003). Jones et al. (2009), however, treated Zalerion maritima as asexual morph of Lulwoana (Lulworthiales) and introduced a new genus, Halenospora to accommodate a non-congeneric species of Zalerion maritima. Hardrospora is a poorly known genus which lacks sequences in GenBank. In this study, the proposal of Zhang et al. (2012) is followed excluding the genus from Phaeosphaeriaceae, based on its morphological characters, and it is tentatively placed in Trematosphaeriaceae. Hadrospora fallax (Mouton) Boise, Mem. N.

Conidiomata walls thin, composed of 2–3 layers, of pale brown cells, arranged in textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells ampulliform, hyaline, smooth, percurrently proliferating at the apex. Conidia subcylindrical, rounded or obtuse at the apex, base truncate, with marginal frill, hyaline, aseptate, smooth-walled, with guttules (from Crous et al. 2014). Type species: Setophaeosphaeria hemerocallidis Crous & Y. Zhang ter, Persoonia, Mol. Phyl. Evol. Fungi 32: 271 (2014). Phylogenetic study: Crous et al. (2014). Notes: Setophaeosphaeria was introduced by Crous et al. (2014). The genus was established to accommodate noncongeneric species of Phaeosphaeria. Crous et al. (2014) introduced two new species, Setophaeosphaeria badalingensis and Sp. hemerocallidis and synonymized Phaeosphaeria setosa under the genus. Crous et al. (2014) mentioned that Setophaeosphaeria differs from the type species of Phaeosphaeria, Ph. oryzae, based on its asexual state. Phaeosphaeria oryzae forms a septoria-like asexual state, while Setophaeosphaeria species form phoma-like asexual states (Quaedvlieg et al. 2013; Crous et al. 2014). Based on phylogenetic analysis, the type species, Setophaeosphaeria hemerocallidis is closely related to Phaeosphaeria setosa, but can be distinguished by dimensions of their spores (Crous et al. 2014). Thus, Crous et al. (2014) introduced a new genus to accommodate these three species in Phaeosphaeriaceae. Phylogenetic analysis of ITS and LSU combined genes (data is not shown) indicates that the type species, Setophaeosphaeria hemerocallidis forms a clade outside Phaeosphaeriaceae, close to Cucurbitariaceae, while Sp. badalingensis clusters with Phaeosphaeria sensu stricto in Phaeosphaeriaceae. Thus, Setophaeosphaeria is polyphyletic and excluded from Phaeosphaeriaceae and tentatively placed in Pleosporales, genera incertae sedis. The second species, Setophaeosphaeria badalingensis may Fungal Diversity (2014) 68:159–238 231 Fig. 32 Hadrospora fallax (BR 5020009617141, holotype). a Fruiting bodies on host surface (BPI 878936). b Section through ascoma (BPI 878936). c Section through peridium (BPI 878936). d Pseudoparaphyses (BPI 878936). e–g Asci (BPI 878936). h–i Ascospores (BPI 878936). j–l Ascospores (BR5020009617141).

Schatz (NY 01319510–NY 01319526). Notes: The monotypic genus Lautitia was introduced by Schatz (1984) as typified by L. danica and placed in Dothideomycetes (Schatz 1984). A detailed description and taxonomic history were given by Wilson and Knoyle (1961) who treated the species then named Didymosphaeria danica (Schatz 1984). Berlese (1892) considered the species as a Leptosphaeria based on its hyaline, 1-septate, immature ascospores. Lind (1913) transferred the species to Didymosphaeria as D. marina (Rostrup) Lind, due to the ascospores turning brown and being 1-septate at maturity.Wilson and Knoyle (1961) could not find brown ascospores, but retained the species in Didymosphaeria. Schatz (1984) disagreed with Wilson and Knoyle (1961) as the species has cellular pseudoparaphyses, while genera in Didymosphaeria have trabeculate pseudoparaphyses. Thus Schatz (1984) designated a new genus, Lautitia, to accommodate the taxon. Schatz (1984) treated Lautitia as a member Phaeosphaeriaceae due to its pseudoparenchymatous to prosenchymatous peridium, and elongate, hyaline asymmetric ascospores. The genus was accepted in Phaeosphaeriaceae by Zhang et al. (2012) and Hyde et al. (2013). In this study, we exclude Lautitia from Phaeaosphaeriaceae based on its morphology. Lautitia can be distingiushed from other genera in Phaeosphaeriaceae which differ in peridium structure, asci and ascospores. Lautitia has prosenchymatous perdial cells, clavate asci with long pedicels, and asymmetric didymosporous ascospores, while other genera in Phaeoaperiaceae have pseudoparenchymatous peridial cells, cylindrical to cylindric-clavate asci which are subsessile to short pedicellate, and phragmosporous, scolecosporous or muriform ascospores (Zhang et al. 2009, 2012; Hyde et al. 2013). It is difficult to place this 233 species in any family or order any thus we refer it to Dothideomycetes, genera incertae sedis. Acknowledgments The Royal Golden Jubilee Ph. D.
