Notes — Lithohypha (as Lithophila) was introduced by Isola et al. (2016) for a fungus growing on marble stone in Italy. Other than the dark brown hyphae with enteroblastic conidiation, it lacked any visible morphology. Lithohypha aloicola is closely related to L. guttulata, but quite distinct morphologically, producing conidia arranged in chains, and occurring on leaves of Aloe in South Africa. Of interest is the fact that both substrates could be regarded as extreme environments.

Notes — Species of Falcocladium are commonly isolated from leaf litter, and considered to be weak foliar pathogens of Eucalyptus (Crous et al. 1994, 1997, 2018a). Five species are presently known, having been collected on eucalypt leaves in Africa, Asia, Australia and South America. Falcocladium eucalypti represents the second species known from Africa, being closely related to F. sphaeropedunculatum, which is distinct in having sphaeropedunculate vesicles (Crous et al. 1997). Of interest is the fact that one collection originates from Australia, suggesting this fungus could have been introduced to South Africa along with its host. Based on a blastn search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 36050 had highest similarity to Falcocladium sphaeropedunculatum (strain CBS 111294, GenBank EU040220.1; Identities = 625/659 (95 %), 15 gaps (2 %)), Falcocladium turbinatum (strain BCC 22055, GenBank NR_138378.1; Identities = 620/688 (90 %), 41 gaps (5 %)), and Falcocladium multivesiculatum (strain CBS 120386, GenBank EU040217.2; Identities = 597/667 (90 %), 46 gaps (6 %)). The ITS sequences of CPC 36046, 36050 and 38019 are identical (650/650 bases). Closest hits using the LSU sequence of CPC 36050 are Falcocladium sphaeropedunculatum (strain CBS 111292, GenBank EU040218.1; Identities = 842/853 (99 %), no gaps), Falcocladium africanum (strain CPC 34007, GenBank MK047471.1; Identities = 851/863 (99 %), no gaps), and Falcocladium thailandicum (strain CPC 13489, GenBank EU040216.2; Identities = 848/861 (98 %), no gaps). The LSU sequences of CPC 36046, 36050 and 38019 are identical (824/824 bases). Closest hits using the actA sequence of CPC 36050 had highest similarity to Falcocladium africanum (strain CBS 145046, GenBank MK047519.1; Identities = 392/407 (96 %), no gaps), Falcocladium thailandicum (strain CBS 121717, GenBank KM231261.1; Identities = 391/407 (96 %), no gaps), and Falcocladium sphaeropedunculatum (strain CBS 111292, GenBank KM231260.1; Identities = 403/428 (94 %), no gaps). The actA sequences of CPC 36050 and 36046 are identical (651/651 bases), and CPC 36050 and 38019 are almost identical (649/652 bases, of which two bases are represented by an extra repetitive nucleotide). Closest hits using the rpb2 sequence had highest similarity to Falcocladium africanum (strain CBS 145046, GenBank MK047533.1; Identities = 720/836 (86 %), no gaps), Trichoderma austriacum (strain CBS 122494, GenBank FJ860525.1; Identities = 688/904 (76 %), 24 gaps (2 %)), and Trichoderma sulawesense (strain G.J.S. 85-228, GenBank AY391954.1; Identities = 681/893 (76 %), 31 gaps (3 %)).

Crous, HPC 2469, culture CPC 35992 = CBS 146022, ITS and LSU sequences GenBank MN562110.1 and MN567618.1. Notes — Gyrothrix is characterised by producing brown, branched, sterile setae that arise from superficial hyphae, and lageniform conidiogenous cells that form hyaline, aseptate, cylindrical to falcate, straight to slightly curved conidia. Gyrothrix is close to Circinotrichum, but distinguished based on its branched setae (Ellis 1971). Gyrothrix eucalypti is distinguished from G. circinata (setae 80–180 µm, conidia 12–15 × 1.5–1.8 µm) and G. podosperma (setae 120–260 µm, conidia 8–16 × 1.5–2 µm) by the dimensions of its setae and conidia (Ellis 1971). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 36066 had highest similarity to Lopadostoma lechatii (strain CBS 133694, GenBank NR_132032.1; Identities = 373/412 (91 %), 16 gaps (3 %)), Calceomyces lacunosus (strain CBS 633.88, GenBank KY610397.1; Identities = 516/583 (89 %), 18 gaps (3 %)), Anthostomella sp.

Notes — Lareunionomyces was established for a genus of hyphomycetes that resembles Sporendocladia, except that it has a more intricate conidiogenous apparatus (Crous et al. 2016b). Lareunionomyces eucalypticola is phylogenetically related to L. loeiensis (on leaf litter, Thailand). The two species are easily distinguished based on their conidiophores, those of the latter being smaller, 90–150(–165) × 5–6.5 μm, and lacking rhizoids (Crous et al. 2018a). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Lareunionomyces loeiensis (strain BCC 84472, GenBank NR_161149.1; Identities = 511/522 (98 %), 1 gap (0 %)), Lareunionomyces eucalypti (strain CPC 32621, GenBank NR_160352.1; Identities = 526/543 (97 %), 3 gaps (0 %)), and Lareunionomyces syzygii (strain CBS 141326, GenBank NR_145315.1; Identities = 532/553 (96 %), 3 gaps (0 %)).

Etymology. Name refers to the host genus Syzygium from which it was isolated. Classification — Mycosphaerellaceae, Capnodiales, Dothideomycetes. Conidiomata globose, brown, 80–120 µm diam, pycnidial, opening via irregular rupture. Conidiophores lining the inner cavity, hyaline to pale brown, subcylindrical, septate, branched or not, 5 – 20 × 3 – 4 µm.

Culture characteristics — Colonies erumpent, spreading, with moderate aerial mycelium and smooth, lobate margin, reaching 6 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface olivaceous grey, and reverse iron-grey. Typus. South africa, Mpumalanga Province, Nelspruit, on leaves of Syzygium cordatum (Myrtaceae), 9 Aug. 2014, P.W. Crous, HPC 2564 (holotype CBS H-24254, culture ex-type CPC 36323 = CBS 146129, ITS, LSU, actA, cmdA and tef1 sequences GenBank MN562119.1, MN567627.1, MN556787.1, MN556793.1 and MN556822.1, MycoBank MB832874). Notes — Colonies were established from single ascospores shot out onto agar. Germinating ascospores were 1-septate, with germ tubes parallel to the long axis of the spore, germinating from both ends, becoming brown, verruculose, 5 µm diam, not to very slightly constricted at the septum. The sexual morph could not be located on the leaf material, but poor sporulation was induced in culture, and two asci were observed. The asexual morph that formed in culture is relatively nondescript, and the taxon is tentatively named in Stomiopeltis based on DNA sequence similarity to other deposited sequences. However, Stomiopeltis has thyrothecia, and thus cannot belong to the Mycosphaerellaceae, further suggesting that the sexual morph of this fungus will have pseudothecial ascomata. Future collections of the sexual morph will hopefully clarify its taxonomy, and its relationship with Stomiopeltis s.str. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Stomiopeltis phyllanthi (voucher MFLU 18-2115, GenBank NR_163328.1; Identities = 389/426 (91 %), 10 gaps (2 %)), Exopassalora zambiae (strain CBS 112971, GenBank NR_156200.1; Identities = 361/400 (90 %), 8 gaps (2 %)), and Clypeosphaerella quasiparkii (strain IHBF 2280, GenBank MF326624.1; Identities = 419/481 (87 %), 16 gaps (3 %)).

Etymology. Name refers to the host genus Eucalyptus from which it was isolated. Classification — Xylariaceae, Xylariales, Sordariomycetes. Colonies established from ascospores shot out onto agar that were aseptate, hyaline, smooth, ellipsoid, resembling those of Neophysalospora and Clypeophysalospora. Conidiomata sporodochial, 180–200 µm diam, buff to pale brown, consisting of densely aggregated conidiophores in mucoid droplet. Conidiophores subcylindrical, smooth, pale brown at base, branched, septate, 20 – 40 × 2 – 3 µm. Conidiogenous cells hyaline to pale brown, smooth, terminal and intercalary, subcylindrical with apical taper, 7–15 × 1.5 – 2 µm, proliferating inconspicuously sympodially at apex. Conidia solitary, aseptate, hyaline, smooth, subcylindrical, apex subobtuse, base truncate, curved, (13 –)15 –17(–18) × 1.5 µm. In older cultures on oatmeal agar acervular conidiomata develop, 200 – 300 µm diam, brown, opening via irregular flaps, containing a similar asexual morph as observed on sporodochia in young colonies. Culture characteristics — Colonies flat, spreading, with moderate aerial mycelium and smooth, lobate margin, reaching 40 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface and reverse rosy buff. Notes — Xylaria eucalypti is tentatively placed in Xylaria, as it is phylogenetically closely related to the genus. However, the fact that it was cultured from neophysalospora-like ascospores, suggests that it probably represents an undescribed genus in Xylariaceae.

Etymology. Name refers to the host genus Olea from which it was isolated. Classification — Xylariaceae, Xylariales, Sordariomycetes. Associated with pale brown, subcircular, amphigenous leaf spots, 1– 3 cm diam, with red brown border. Cultures were derived from 1–3-septate fusoid, brown ascospores, but ascomata could not be located on host material. Mycelium consisting of hyaline, smooth, branched, septate, 1.5 – 2 µm diam hyphae. Conidiophores solitary, erect, medium brown, smooth, 1– 2-septate, subcylindrical with apical taper, 30 – 50 × 3 µm. Conidiogenous cells integrated, terminal, medium brown, smooth, 20–30 × 2–3 µm, forming a rachis with sympodial loci, pimple-like, 0.5 µm diam, not thickened nor darkened.

Notes — The genus Clypeosphaeria (based on C. mamillana) is a member of the Xylariaceae, and has brown, septate ascospores (Jaklitsch et al. 2016). Although the sexual morph of the present collection could not be traced (other than the geminating ascospores shot out onto agar plates), the xylariaceous asexual morph, ascospores, and DNA phylogeny suggest that it is presently best to accommodate it as a new species of Clypeosphaeria. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Anthostomella eucalyptorum (strain 2741, GenBank AM922205.1; Identities = 432/478 (90 %), 9 gaps (1 %)), and Digitodochium rhodoleucum (strain NBRC 32296, GenBank LC146732.1; Identities = 434/491 (88 %), 23 gaps (4 %)).

Etymology. Name refers to the host genus Maytenus from which it was isolated. Classification — Leptosilliaceae, Xylariales, Sordariomycetes. Conidiomata solitary to aggregated, pycnidial, globose, brown, 180 – 200 µm diam, with central ostiole; wall of 6 – 8 layers of pale brown textura angularis. Conidiophores lining the inner cavity, hyaline, smooth, subcylindrical, 0 – 3-septate, branched at base or not, 7– 30 × 1.5 – 2 µm. Conidiogenous cells hyaline, smooth, subcylindrical, 5–8 × 1.5 µm, proliferating percurrently at apex, at times with three conidia still attached to apex. Conidia hyaline, smooth, aseptate, bean-shaped, slightly curved, inequilateral, inner plane flat, outer plan convex, apex and base rounded toward inner plane, (4 –)5(– 6) × 1.5 µm. Culture characteristics — Colonies erumpent, spreading, with moderate aerial mycelium and smooth, lobate margin, reaching 50 mm diam after 2 wk at 25 °C. On MEA surface dirty white, reverse cinnamon.

Notes — The genus Leptosillia was recently treated by Voglmayr et al. (2019). Although L. mayteni was isolated from leaves, most species of Leptosillia are isolated from bark and twigs. Morphologically, the asexual morph of L. mayteni is most similar to that of L. wienkampii, conidia (5 –)5.5 – 6.2(–7) × (1.4–)1.6–1.9(–2.1) μm, although the two species are phylogenetically quite distinct. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Leptosillia wienkampii (as Leptosillia sp.

Notes — Dactylaria is characterised by having hyaline conidiophores and septate, hyaline conidia formed on denticles (De Hoog 1985). The genus Dactylaria is polyphyletic, and the phylogeny of its type species (D. purpurella) remains unresolved. Nothodactylaria nephrolepidis resembles Dactylaria, but clusters apart from other species considered to belong to Dactylaria s.lat.

Notes — Cyphellophora is characterised by pigmented phialides occurring directly on hyphae or occasionally on flaskshaped conidiogenous cells, and producing small clusters of olivaceous, septate, mostly curved conidia (Cheewangkoon et al. 2009, Crous et al. 2019b). Cyphellophora goniomatis is phylogenetically related to C. guyanensis (from angiosperm, French Guyana, conidia (2–)3–6-septate, (18–)19.7–28(–29) × 1.5–2 µm; Decock et al. 2003), although it has smaller conidia.

Notes — Scolecobasidium represents an older name for the genus commonly referred to as Ochroconis (Seifert et al. 2011). Scolecobasidium blechni is phylogenetically related to Ochroconis cordanae (conidia 1-septate, obovoidal to broadly fusiform, ((5 –)7– 9(–10) × (2.5 –)3 – 3.5 μm; Samerpitak et al. 2014) and O. macrozamiae ((5–)8–10(–12) × (3–)3.5(–4) μm; Crous et al. 2014), but is distinct based on its slightly longer conidia and DNA phylogeny. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Ochroconis cordanae (strain CBS 101179, GenBank KF156020.1; Identities = 548/622 (88 %), 42 gaps (6 %)), Ochroconis macrozamiae (strain CBS 102491, GenBank KF156021.1; Identities = 569/653 (87 %), 48 gaps (7 %)), and Ochroconis musae (strain CBS 145061, GenBank MK442605.1; Identities = 353/404 (87 %), 16 gaps (3 %)).

Notes — Strelitziomyces is closely related to Anungitiomyces, a monotypic genus occurring on Eucalyptus leaf litter in South Africa (Crous et al. 2019a). Anungitiomyces is characterised by brown, erect conidiophores, 0–1-septate, obclavate, hyaline conidia, arising via sympodial conidiogenesis. The main differences between the two genera lie in the lack of pigmentation in Strelitziomyces, and the prominently formed sclerotiumlike bodies. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Anungitiomyces stellenboschiensis (strain CPC 34726, GenBank MK876376.1; Identities = 537/616 (87 %), 31 gaps (5 %)), Rhinocladiella pyriformis (strain CBS 469.94, GenBank MH862476.1; Identities = 379/434 (87 %), 15 gaps (3 %)), and Pseudotruncatella arezzoensis (strain MFLUCC 14-0988, GenBank NR_157489.1; Identities = 352/399 (88 %), 19 gaps (4 %)).

Etymology. Name refers to the host genus Podocarpus from which it was isolated. Classification — Sympoventuriaceae, Venturiales, Dothideomycetes. Mycelium consisting of smooth, medium brown, septate, branched, 1.5 – 2 µm diam hyphae, forming hyphal coils. Conidiophores erect, 1-septate, unbranched, medium brown, smooth, subcylindrical, 9–17 × 2.5–3 µm.

Notes — Scolecobasidium podocarpicola is related to but distinct from species of Scolecobasidium (incl. Ochroconis) based on its conidial morphology, being subcylindrical, 1(– 3)septate, (19 –)22 – 25(– 26) × (2.5 –)3 µm. Of interest is the fact that S. podocarpicola was cultured from spermatia oozing from a spermatogonium, suggesting that it could have a sexual morph, and that it proved to be closely related to a sexual species, Ochroconis sexualis (Samerpitak et al. 2014). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Ochroconis sexualis (strain PPRI 12991, GenBank NR_132049.1; Identities = 454/522 (87 %), 22 gaps (4 %)), Ochroconis mirabilis (strain UTHSC 04-2378, GenBank LM644513.1; Identities = 416/495 (84 %), 32 gaps (6 %)), and Ochroconis icarus (strain CBS 536.69, GenBank MH859368.1; Identities = 400/476 (84 %), 26 gaps (5 %)).

Etymology. Name refers to the host genus Podocarpus from which it was isolated. Classification — Chaetothyriaceae, Chaetothyriales, Eurotiomycetes. Mycelium consisting of pale brown, smooth, septate, branched, 2–3 µm diam hyphae. Conidiophores reduced to phialidic conidiogenous cells arising from superficial hyphae, separate, not aggregated in clusters, ampulliform to subcylindrical, medium brown, smooth, 3 –7 µm long, apex with long cylindrical neck, 1– 3 µm long, slightly flared, base frequently ellipsoid, 3 –7 µm diam, attached to hyphae laterally via small hyphal peg.

Notes — Ceramothyrium podocarpicola is phylogenetically related to Ceramothyrium, an epiphyllous genus of ascomycetes with Stanhughesia asexual morphs (see Ceramothyrium podocarpi; Crous et al. 2012a). Morphologically, the present collection is quite distinct from Stanhughesia, but we suspect that what we observed in culture is actually a synasexual morph, as the species was originally isolated as a Stanhughesia morph from Podocarpus leaves. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Chaetothyrium agathis (strain MFLUCC 12-0113, GenBank NR_132914.1; Identities = 451/509 (89 %), 22 gaps (4 %)), Ceramothyrium exiguum (strain VTCC F-1209, GenBank NR_159757.1; Identities = 438/499 (88 %), 18 gaps (3 %)), and Ceramothyrium exiguum (strain VTCC F-1209, GenBank LC360297.1; Identities = 438/499 (88 %), 18 gaps (3 %)).

Notes — Pseudopenidiella is characterised by having erect, brown conidiophores, sympodial conidiogenesis, and aseptate conidia with somewhat thickened scars and hila (Bensch et al. 2012, Crous et al. 2012b). Pseudopenidiella podocarpi is related to P. piceae (ramoconidia 8 – 12 × 2 – 3 μm, conidia (6 –)7– 9(–10) × (2.5 –)3 μm; Crous et al. 2012b), but distinct in having larger conidia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 37092 had highest similarity to Pseudopenidiella piceae (strain CBS 131453, GenBank NR_111761.1; Identities = 443/484 (92 %), 9 gaps (1 %)), Morenoina calamicola (strain MFLUCC 14-1162, GenBank NR_154210.1; Identities = 327/394 (83 %), 20 gaps (5 %)), and Leptomelanconium allescheri (strain LA_ kult_01, GenBank MF573935.1; Identities = 314/376 (84 %), 21 gaps (5 %)).

Etymology. The famous milkwood tree in Mossel Bay is over 500 years old. It is commonly known as the Post Office Tree, as in 1500 a sailor left a letter in a shoe at the tree, found by Joao da Nova in 1501 en-route to India. Name derived from L. postalis = postal, and L. officium = service; isolated from leaf litter of the Post Office Tree. Classification — Nectriaceae, Hypocreales, Sordariomycetes. Conidiophores penicillate, comprising a stipe, a penicillate arrangement of fertile branches, a stipe extension and a terminal vesicle; stipe septate, hyaline, smooth, 30–60 × 4–6 µm. Stipe extension aseptate, straight, thick-walled, 100 –150 µm long, with a basal septum, terminating in a thin-walled, narrowly lanceolate to ellipsoid vesicle, 3.5–4 µm wide. Penicillate conidiogenous apparatus with primary branches aseptate, 12–25 × 3.5 – 5 µm, secondary branches aseptate, 18 – 22 × 3.5 – 4 µm, tertiary branches 12–15 × 3.5–4 µm, each terminal branch producing 2 – 4 phialides; phialides cymbiform to cylindrical, hyaline, 12 –15 × 2.5 – 4 µm, with minute periclinal thickening and cylindrical collarette. Conidia cylindrical, rounded at both ends, straight, 1-septate, (10 –)14 –15(–17) × 2(– 2.5) µm, straight, held in clusters by colourless slime.

Etymology. Name refers to its morphological similarity with Periconia brittanica. Classification — Periconiaceae, Pleosporales, Dothideomycetes. Mycelium consisting of brown, verruculose, branched, septate, 2–3 µm diam hyphae. Conidiophores dimorphic. Microconidiophores reduced to conidiogenous cells occurring directly on hyphae, tretic, giving rise to a single conidium, but at times also clusters of conidial chains occur. Macroconidiophores 100–300 × 10–17 µm, solitary, or in clusters of 2–3, arising from a brown stroma, subcylindrical, straight to flexuous, unbranched, dark brown, smooth, thick-walled, base swollen, 15 – 25 µm diam; stipe mostly aseptate, with 2 – 5 septa in upper conidiogenous region; primary branches subcylindrical, brown, verruculose, 0 –1-septate, 10 – 25 × 7–10 µm. Conidiogenous cells terminal and intercalary, occurring in an apical chain on primary, or directly on conidiophore, 10–15 µm long, tretic. Conidia aseptate, spherical, pale to medium brown, with delicate spines, occurring in branched chains, (6 –) 8 –10(–12) µm diam; conidiogenous apparatus usually unilateral on conidiophore. Culture characteristics — Colonies flat, spreading, with sparse aerial mycelium and even margin, covering dish after 2 wk at 25 °C. On MEA, PDA and OA surface and reverse iron-grey. Notes — Periconia was treated by Tanaka et al. (2015). Periconia neobrittanica is similar to P. britannica in having unilateral conidiophores and micro- plus macroconidiophores. It is distinct in that it has larger conidia with delicate spines, and shorter conidiophores (Ellis 1976). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Ascomycete sp. (strain nasa64 from the Atcama desert in Chile, GenBank DQ683977.1; Identities = 528/528 (100 %), no gaps), Periconia aquatica (strain HKAS 92754, GenBank NR_158841.1; Identities = 438/475 (92 %), 5 gaps (1 %)), and Periconia submersa (strain HKAS 92738, GenBank NR_158842.1; Identities = 437/476 (92 %), 6 gaps (1 %)). The ITS sequence is 90 % (439/487, including 11 gaps) similar to Noosia banksiae (strain CPC 17282, GenBank JF951147.1), which represents the most similar species obtained when the LSU sequence was used in the megablast search.

Notes — The Camarosporium complex was recently treated by Wanasinghe et al. (2017). Pseudocamarosporium eucalypti is closely related to P. brabeji (on branch of Platanus sp., Switzerland, conidia ellipsoid or subcylindrical, (9 –)10 –12(–13) × (4 –)5(– 6) μm, 1– 3-transversely septate; Crous et al. 2018b), from which it is distinct by having smaller, 1-septate conidia, (7–)8 – 9(–10) × (4–)5 µm. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Pseudocamarosporium brabeji (strain NWFVA2387, GenBank MG098280.1; Identities = 581/588 (99 %), no gaps), Pseudocamarosporium tilicola (strain MFLUCC 13-0550, GenBank KJ747050.1; Identities = 551/558 (99 %), no gaps), and Pseudocamarosporium piceae (strain cp48, GenBank MK796148.1; Identities = 518/525 (99 %), no gaps).

Notes — Based on the morphology on the host material, the present collection is a passalora-like fungus in the sense of Crous & Braun (2003), but based on its morphology in culture, it is a typical Pseudocercospora (Crous et al. 2013a, Videira et al. 2017). No species of Pseudocercospora is presently known from Heteropyxis natalensis, and thus it is herewith described as new. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Pseudocercospora tamarindi (strain MFLUCC 140805, GenBank KP744461.1; Identities = 496/509 (97 %), 1 gap (0 %)), Pseudocercospora eriodendri (GenBank AF222840.1; Identities = 494/508 (97 %), no gaps), and Pseudocercospora punctata (strain CBS 113315, GenBank EU167582.1; Identities = 524/542 (97 %), no gaps).

Etymology. Name refers to the host genus Juncus from which it was isolated. Classification — Cladosporiaceae, Capnodiales, Dothideomycetes. Ascomata pseudothecial, dark brown, erumpent, globose, 80– 120 µm diam, with central ostiole 10 µm diam; ascomata aggregated in clusters and linked via a brown stroma (in agar, not observed on host); wall of 2–3 layers of brown textura angularis. Asci aparaphysata, fasiculate, bitunicate, subsessile, obovoid, straight to slightly curved, 8-spored, with apical chamber, 30 – 35 × 9 –10 µm. Ascospores multiseriate, hyaline guttulate, constricted at median septum, thick-walled, surrounded by mucoid sheath, tapering towards both ends, but more prominently towards lower end, (9–)11–12(–13.5) × (3.5–)4 µm. Ascospores germinating initially via both ends, 5 – 6 µm diam, becoming brown, verruculose, with mucoid sheath, distorting, the two original ascospore cells dividing into two; outer two cells germinating via two germ tubes parallel to the long axis, inner two cells germinating later, with germ tubes perpendicular to the long axis of the ascospore. Culture characteristics — Colonies flat, spreading, with sparse aerial mycelium and smooth, lobate margin, reaching 30 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface and reverse olivaceous grey. Typus. USA, California, Davis, UC Davis, on culms of Juncus effusus (Juncaceae), 2 Apr. 2019, P.W.

Notes — Cytosporella has eustromatic conidiomata, opening by irregular dehiscence, branched phialidic conidiophores, and hyaline, aseptate, thin-walled, ellipsoid conidia (Sutton 1980). Although the taxonomy of Cytosporella is still in flux, the present collection is tentatively placed in this genus. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had distant hits with Neoacrodontiella eucalypti (strain CBS 145561, GenBank MK876396.1; Identities = 374 / 427 (88 %), 24 gaps (5 %)), Corticifraga peltigerae (strain RP282, GenBank KY661634.1; Identities = 268/289 (93 %), 9 gaps (3 %)), and Taitaia aurea (voucher TU 56326, GenBank NR_160480.1; Identities = 197/203 (97 %), 1 gap (0 %)).

Moreno, Carlavilla, Bellanger, Olariaga, P.-A. Moreau, Bidaud, Loizides & Manjón, sp. nov. Etymology. Referring to its Mediterranean distribution. Classification — Bankeraceae, Thelephorales, Agaricomycetes. Basidiocarps annual, with a central or eccentric stipe. Cap 4–12 (–15) cm broad, convex to plane-convex, later depressed at centre, colour variable, pale grey, brownish grey to ochraceous brown or dark brown when mature, surface dry, smooth, innately fibrillose, breaking up into small scales or cracked, especially at centre; context in cap very pale grey to grey, very pale red when cut, with green tones when desiccated or with 5 % KOH (no reaction with H2O and 5 % NaOH). Margin straight, irregular, concolorous or slightly paler, not hygrophanous, smooth, often incised due to its thinness. Pores small, 1– 3 per mm, round to angular, whitish turning slightly very pale grey upon bruising, grey brown when desiccated. Tubes 2 – 5 mm thick, decurrent, tightly adhered to the context. Stem 2.5–7 × 1–3 cm, cylindrical, sometimes curved, central or eccentric, solid, tapering downwards, of the same colour as the cap or paler, greyish white at the apex, surface smooth to slightly squamulose; context in stem very pale greyish white. Odour not distinctive or sometimes farinaceous, taste bitter in young specimens. Context with green tones when desiccated. Spores 4.5 – 6.7 × 3.3 – 5.2 µm, av. 5.6–4.3 µm (holotype), Qav: 1.3 (n = 20), globose to subglobose, nodulose, without iodine reactions, colourless to very pale yellow-brown; ornamentation formed by broad obtuse nodules appearing furcate. Basidia 4-spored, (14 –)18 – 24 × 5 –7 µm, sterigmata up to 4 µm long, clavate, hyaline. Pleurocystidia and cheilocystidia absent. Context formed by hyphae 1– 2 µm broad. Pileipellis a cutis with cylindrical hyphae, septate, thinwalled to slightly thick-walled (2.5 – 4 µm diam), swollen at septa (8 –10(–16) µm diam), clamped, hyaline or with a faint olivaceous hue in H2O and 5 % KOH. Hyphal system monomitic, hyphae hyaline, thin-walled, clamped. Habitat & Distribution — Growing solitary to gregarious on basic and acidic soils, mainly under Pinus spp. Typus. Spain, Madrid, San Martín de Valdeiglesias, Las Cruces, 30TUK8365, 810 m, under Pinus pinaster, P. pinea, Quercus ilex subsp. ballota and Cistus ladanifer, on acid soil, 30 Nov. 2013, J.C. Campos & M. Hinojosa (holotype AH 44080, ITS and LSU sequences GenBank MN536723 and MN535629, MycoBank MB832765). Notes — Boletopsis mediterraneensis is characterised by its medium to large size, a cap generally not black but with grey or brown tones, with context becoming very pale red when cut, turning green with KOH and acquiring conspicuous green tones when dry. So far, B. mediterraneensis is only known from the Mediterranean area, mostly under Pinus, but also under Cedrus. Our ITS-LSU analyses recovered specimens of B. mediterraneensis in a well-supported clade (see Supplementary Fig. FP1001-2), weakly supported as sister to B. nothofagi, and distinct from other well-supported clades corresponding to B. grisea, B. leucomelaena and B. watlingii. The latter three species form a major supported clade. Although the B. mediterraneensis clade shows phylogenetic structure, attempts to find correlated morphological, ecological or macrochemical characters defining the three major subclades were unsuccessful. Thus, we treat B. mediterraneensis as a single species, rather than a clade including several cryptic species. Boletopsis mediterraneensis has so far been mistaken for B. grisea, and most Mediterranean records of the latter may correspond in fact to B. mediterraneensis. Both species constitute two distinct and well-supported clades (see Supplementary Fig. FP1001-2). Boletopsis grisea is very similar to B. mediterraneensis, but the former differs by its context turning only faintly greenish in KOH in fresh specimens, and black brown upon drying (Niemelä & Saarenoksa 1989). According to our observations, the two species have different distributions. Whereas B. grisea is broadly distributed in the Eurosiberian area and is extremely rare in the Mediterranean area, B. mediterraneensis has a mostly Mediterranean distribution. Boletopsis leucomelaena is characterised by its greyish sepia to black-brown cap surface, turning sepia black in KOH, and by its association with Picea (Niemelä & Saarenoksa 1989). Boletopsis nothofagi has a cap turning blackish upon bruising, becoming black with KOH and is associated with Nothofagus in the Southern Hemisphere (Cooper & Leonard 2012). Boletopsis watlingii (= B. perplexa), described using European material, differs from B. mediterraneensis by its dark cap and slightly smaller basidiospores (4.5 – 4.8(– 5) × 3.5– 4.5 μm) (Watling & Milne 2006).

Pham, A.V. Alexandrova & O.V. Morozova, sp. nov. Etymology. The epithet refers to the pure white colour of the basidiomata. Classification — Boletaceae, Boletales, Agaricomycetes. Basidiomata medium sized, boletoid. Pileus 18 ‒ 35 mm diam, initially hemispherical, becoming convex with slightly appendiculate margin, projecting 1– 2 mm beyond the pores, white (4A1, Kornerup & Wanscher 1978), cream (4A2 ‒ 3) on drying, surface dry, velutinous, tomentose or felted. Hymenophore adnate, up to 4 mm thick, white, becoming cream, except for the edge of the tubes that remain white; pores almost not seen due to long cheilocystidia, round or angular under the cheilocystidia layer, up to 0.3 mm diam. Stipe 60 – 80 × 6 – 8 mm, almost cylindrical, broadened slowly towards the base, solid; longitudinally irregularly striate to irregularly reticulate in an upper part; dry, with transparent drops of exudate in the lower part; white (4A1). Context white, with darker hygrophanous spots in the upper part of stipe, unchanging. Smell weak, taste mild. Spores (12.5 –)13.5 –14(–15.5) × (3.5 –)4 – 5(– 5.5) μm, Q = (2.5 –)3 – 3.5(– 4), fusoid, subfusoid and inequilateral in side view with weak suprahilar depression, yellowish brown in KOH, smooth. Basidia 32–41 × 9.5–11 μm, 4-spored, narrowly clavate to clavate, clampless. Cheilocystidia cylindrical to narrowly clavate, sometimes septate, with terminal cells 37– 85 × 6 – 8 μm, often thick-walled in the upper part, hyaline, forming sterile tube edge. Pleurocystidia 41–70 × 8 –11 μm, lageniform or fusiform. Hymenophoral trama divergent, boletoid. Pileipellis a trichoderm, made up of palisade of chains of swollen elliptic cells, 27– 56 × 12 –15 μm, larger in the base of hairs, smaller in their apex, end cells conical or lageniform or tapering into the long neck, 23 – 52 × 7–13 μm, hyaline. Stipitipellis a caulohymenium of basidiolae-like clavate cells, 19–30 × 7–10 μm, with scattered basidia. Caulocystidia 55–110 × 11–15 μm, cylindrical to narrowly clavate, usually septate. Clamp connections absent. Habit, Habitat & Distribution — Solitary or in groups on soil in evergreen tropical forests. Known from Vietnam. Typus. Vietnam, Dak Lak Province, Krong Bong District, Chu Yang Sin National Park, Krong Kmar, 8 km west of Chu Yang Sin, 12.37958°N, 108.3523°E, 1 680 m alt., mountain polydominant rainforest with the participation of Fagaceae, Magnoliaceae, Theaceae, Podocarpaceae, 1 Apr. 2013, A.V.

Vietnam, Dak Lak Province, Krong Bong District, Chu Yang Sin National Park, Krong Kmar, 7 km northwest of Chu Yang Sin mountain, 12.414833°N, 108.378222°E, 1 240 m alt., mountain polydominant rainforest with the participation of Fagaceae, Magnoliaceae, Theaceae, Podocarpaceae, 27 May 2014, A.V. Alexandrova & T.H.G. Pham (LE315543, ITS sequence GenBank MN511176). Notes — Boletus candidissimus is characterised by the pure white basidiomata and pileipellis structure consisting of a palisade of hairs composed of chains of swollen elliptic cells, ending by conical or lageniform cells, sometimes tapering into the long neck. White forms lacking pigment appear in the different groups of boletoid fungi. Due to the appendiculate pileus margin and fusoid spores it resembles Leccinum species, from which it differs by the special pileipellis structure, not squamulose stipe and lack of any colour changes of context. Superficially B. candidissimus is close to B. purus (Corner 1972), although that species possesses large clavate cheilocystidia, and a pileipellis consisting of a palisade of clavate cells. The North American species Tylopilus rhoadsiae (Bessette et al. 1999) differs by the adnexed hymenophore, pileipellis and stipitipellis structure, bitter taste and an association with pine. In the phylogenetic tree, sequences of the species are nested within the /Boletoideae clade (data not shown) in the sense of Wu et al. (2016). They do not cluster with any known boletoid genera. In spite of this, we avoid introducing a new genus until more data becomes available. Colour illustrations. Vietnam, Dak Lak Province, Krong Bong District, Chu Yang Sin National Park, type locality.

Additional material examined. braZil, Rio Grande do Norte, Parque Estadual Dunas do Natal, soil, 5 July 2008, E.P. Fazolino (UFRN-Fungos 776). Notes — Based on morphological and molecular characters, Bovista psammophila belongs to the subgenus Globaria, in the genus Bovista (Kreisel 1967), and is recognised by its granulose exoperidium, capillitium lycoperdon-type along the gleba, with numerous pores, presence of mycosclereids in the inner layer of the exostratum, and verrucose basidiospores. Bovista psammophila is closely related to B. aestivalis, B. furfuracea, and B. himalaica. However, B. aestivalis exhibits a compact subgleba, an intermediary-type capillitium in the centre of the gleba with numerous pores, and globose to ovoid basidiospores (Calonge & Demoulin 1975, Demoulin 1979), characters not found in B. psammophila. Bovista furfuracea is morphologically similar to B. psammophila, but B. furfuracea has a lycoperdontype capillitium, with fragile hyphae and numerous septa, smooth to verruculose basidiospores, and a robust rhizomorph (Moyersoen & Demoulin 1996). Bovista himalaica exhibits globose to pyriform basidiomata, rudimentary subgleba, and intermediary-type capillitium along the gleba with no pits (Yousaf et al. 2013), which differs from B. psammophila. Morphological and molecular data (ITS nrDNA) show B. psammophila as a distinct new species. Subgen. Bovista 0.78 0.97 0.98 1 Gen.

Alvarado & Requejo, sp. nov. Etymology. The epithet refers to the place where it was found (Illa de Cortegada, Parque Nacional Marítimo-Terrestre de las Islas Atlánticas, Galicia, Spain). Classification — Hyaloscyphaceae, Helotiales, Leotiomycetes. Apothecia solitary to gregarious (–5), with a short but stout stipe, disc flat to slightly concave, finely pruinose, 0.1– 0.4 cm diam when dry, 0.2 – 0.5 cm upon rehydration; translucent brown to pale yellowish brown when fresh, beige brown to bluish brown when dry; margin elevated, occasionally slightly incurved due to hairs, pruinose, white when dry; receptacle concolorous with the disc or slightly paler, furfuraceous, pruinose when dry. Flesh concolorous with the disc too, or slightly paler. Not hygrophanous. Asci containing 8 uniseriate to biseriate spores, (40–)42–48(–53) × 3.5–4.5(–5) µm, cylindrical to subcylindrical, with a simple septum at the base and a conical or obtuse apex, with a small apical ring structure of the Calycina-type, slightly bluish to brownish red in Lugol´s solution (IKI: 1 % I2; 3 % KI). Ascospores ellipsoid with obtuse apices, hyaline, smooth, with one drop at each end (about 0.5 µm diam), aseptate, about 4–6.5(–7.5) × 2–2.8; 5.2 ± 0.6 × 2.3 ± 0.3, Qn = 2.5 (n = 36) µm after death. Paraphyses filiform, unbranched, 1.75–2(–3.7) µm diam, not exceeding the length of asci, with a rounded apex and abundant small vacuoles, sometimes presenting several septa at the base, Ectal excipulum composed of parallel, slightly interwoven hyphae of (4.5 –)5.5 –7(–10) µm diam, brown coloured with bluish tinges. The terminal cells of the calycle edge are hyphoid, with rounded apices of up to 9 µm wide. Medullary excipulum arranged as a textura porrecta, with disordered, interwoven gelatinized elements. Distribution — Currently known only from the type location in north-western Spain. Phylogeny — The analysis of ITS rDNA suggests that the specimen found in Cortegada represent a distinct lineage of Calycina (clade 2 in Han et al. 2014). No significant phylogenetic relationships with other species of this genus could be inferred, but sub-significant values (PP 0.89, BP 68) suggest a putative relation with C. marina. Notes — Calycina cortegadensis is characterised by its apothecia with an apical disc furfuraceous-pruinose but lacking external hairs, its yellowish beige to bluish brown tones when dried, and its spores measuring 4 – 6.5(–7.5) × 2 – 2.8 µm. The recently proposed lichenicolous species C. alstrupii has similar spore dimensions, (5 –)5.8(–7) × (1.5 –)2.03(– 2.5) µm, but those of C. cortegadensis can be as short as 4 µm. In addition, the apical ring of asci in C. corticatensis becomes slightly blue to reddish brown in Lugol, and young ascomata of C. alstrupii are yellowish cream to pale orange (Suija & Motiejūnaitė 2017). Other species similar to C. alstrupii such as C. venceslai and C. langida can be found in the same locality, but they have different spore dimensions and lack the beige-brown to bluish brown tones when dry (Suija & Motiejūnaitė 2017). The putative phylogenetic relationship with C. marina is not supported by any shared ecological or morphological trait, since C. marina fruits over seaweed, develops pulvinate ascocarps, has spores 8 –13 × 3.3 – 4(– 4.5), and claviform to capitate multiseptate paraphyses (Baral & Rämä 2015).

Habit, Habitat & Distribution — In small groups on poor sandy and clay soil not far from ponds, in a heathland with lichens (Cladonia sp.), and surrounded by Erica arborea, E. cinerea, Calluna vulgaris, Ulex europaeus and Pinus pinaster. Other rare and interesting species found at the same locality included Arrhenia chlorocyanea, Hydropus moserianus, Galerina nana, Psathyrella flexispora, Plectania rhytidia and Rommelaarsia flavovirens.

Notes — Because of its viscid pileus and stipe, decurrent lamellae with non-gelatinised edge but with interwoven trama and sometimes constricted and white spores, this new species fits the genus Chromosera subgenus Oreocybe (Boertmann 1990, Lodge et al. 2013) that already includes C. xanthochroa, C. citrinopallida and C. lilacina. According to Boertmann (1990, 2010), Candusso (1997) and Borgen & Arnolds (2004), C. citrinopallida and C. lilacina have an arctic and alpine distribution while C. xanthochroa can also be found in oceanic temperate areas. Because of its habitat, C. ambigua could therefore be compared with C. xanthochroa, but the latter has the narrowest spores of the subgenus, measuring on average less than 4.5 µm diam, while the average width of the spores of our new species easily reaches 5 µm diam. On the other hand, considering the three species with spores on average larger than 4.5 µm, C. citrinopallida is chrome-yellow and pales to white as it ages, and therefore never presents lilac tones, while C. lilacina has a brownish orange to lilac cap and a lilac stem (Consiglio 1997, Hausknecht et al. 2003, Consiglio & Contu 2007, Boertmann 2010). But as already pointed by Boertmann (1990) and Consiglio & Contu (2007), discoloured specimens of the last two species can only be distinguished by their ecological preferences, C. lilacina being more hygrophilous than C. citrinopallida. Without considering the different ecological preferences of the species, yellow and lilac specimens of C. ambigua can therefore be respectively confused with C. citrinopallida and C. lilacina, from which they differ essentially by their always clearly striate cap vs ‘sometimes short translucently striate from margin’ or ‘± translucently striate’ (Boertmann 2010, see also Borgen & Arnolds 2004). Chromosera viola, which belongs to the subgenus Subomphalia, is readily distinguished by its completely dry pileus and stipe and broad, subglobose and non-constricted spores (Boertmann 2010, Lodge et al. 2013, Sánchez & Gibert 2015).

Culture characteristics — (after 2 wk at 20 °C in the dark): On potato dextrose agar colonies reach 29–32 mm diam, without the presence of diffusible pigments and/or exudates. The morphology of the colony seen on the back is characterised by a velvety mycelium immersed in the agar, radially furrowed, olive-green, while on the obverse of the plate the colony has a flat growth, with a somewhat elevated colony centre, velvety olive-black colour, and dense sporulation. In the outer part of the colony, there is an edge with a white filiform margin. On oatmeal agar the colony reaches 32 – 35 mm diam without presence of diffusible pigments and/or exudates. The colony has round shape, with abundant velvety olive-green aerial mycelium immersed in the agar, profuse sporulation, and presents filiform edges. On malt extract agar, the colony reaches 25 – 27 mm diam, and does not produce diffusible pigments and/or exudates. The colony seen on the back has a rounded shape, dark green colour and opaque texture. On the obverse of the plate, the colony has a flat growth with abundant aerial velvety mycelium of olive-yellow colour immersed in the agar, and filiform edges. On synthetic nutrient-poor agar, colonies reach 23–25 mm diam without presence of diffusible pigments and/or exudates. On the reverse of the plate, a flat round colony of dark green colour is observed. On the obverse of the plate, the colony has olive-green aerial mycelium and profuse sporulation mainly in the centre of the colony. Cardinal temperature for growth — Optimum 20 °C, maximum 25 °C, minimum 5 °C. Notes — Based on the combined analysis of ITS, actA and tef1 markers, Cladosporium fildesense belongs to the C. herbarum complex (Bensch et al. 2015) and is phylogenetically related to C. soldanellae, C. ossifragi and C. spinulosum. Cladosporium spinulosum differs from our new species by the digitate ornamentation of conidia and the absence of secondary ramoconidia (Zalar et al. 2007). Regarding C. soldanellae, this species has stromatic cells and occasionally forms ramoconidia (Bensch et al. 2012) while C. fildesense does not show stromatic cells and ramoconidia were always observed. Finally, C. ossifragi differs from C. fildesense by having shorter conidiogenous cells (5–31 μm long), the muricate conidial ornamentation, and by lacking primary ramoconidia (Schubert et al. 2007). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence are Cladosporium ramotenellum (GenBank MF473250.1; Identities 549/ 549 (100 %), no gaps), Cladosporium cladosporioides SLBB (GenBank JN565298.1; Identities 549/549 (100 %), no gaps), and Cladosporium cucumerinum (GenBank DQ681347.1; Identities 549/551 (99 %), 2 gaps (0 %)).

Notes — Clavulina iris is a species of exceptional morphochromatic variability, often displaying a blend of ochraceous, cream, pink, green and lilac colours all in the same specimen, as well as a mixture of smooth and rugose branches with both blunt and cristate tips. It is common on the island of Cyprus, where it is found from late winter to early spring in a variety of calcareous habitats (300–700 m asl). Lilac tinges are present in very few European species of Clavulina, most notably C. amethystina (Donk 1933), a species originally described in genus Clavaria by Bulliard (1791). European collections identified as this taxon, however, display vibrant violet-lilac colours (Corner 1970), lacking the ochraceous, cream or green tinges seen in C. iris, and cluster in a different phylogenetic lineage (Olariaga et al. 2009; Supplementary Fig. FP1007-1). Clavulina reae, proposed by Olariaga & Salcedo (2012) for collections previously identified as ‘C. cinerea var. gracilis’ (Rea 1918), is also characterised by lilac-grey tinges, but produces smaller, slender and sparsely branched fruit bodies nesting in a distant lineage (Olariaga et al. 2009; Supplementary Fig. FP1007-1). Among the many forms and variants of C. cinerea formerly described, ‘Clavaria cinerea f. sublilascens’ (Bourdot & Galzin 1928), later invalidly renamed ‘Clavulina crassa’ by Corner (1950), is morphologically close to C. iris. We refrain from adopting Bourdot & Galzin’s epithet, because the very short original description could also apply to C. reae, among others, but also because the Arvernian authors did not prospect Mediterranean localities in their description, with their collections likely originating from temperate deciduous forests, where C. iris has yet to be documented. Clavulina iris var. occidentalis Bellanger, P.-A. Moreau & Loizides, var. nov. Differs from the type by more slender, smooth basidiomata and abundant pseudocystidia. Typus. france, Pézilla-de-Conflent, Pathy-Danglade, 26 Nov. 2012, P.-A. Moreau & F. Richard (holotype in Herbarium of the Faculty of Pharmacy of Lille: LIP 0401619; isotype in herb. pers. P.-A. Moreau n° PAM12112617, ITS sequence GenBank MN028410, MycoBank MB832819). Notes — The variability of C. iris is also geographical and, to some extent, phylogenetic. In the type collections from Cyprus specimens are usually stout, early rugose and with few pseudocystidia. Collections from France, on the other hand, all found under Quercus ilex in late autumn, are more slender, smooth and with abundant pseudocystidia (Supplementary Fig. FP1007-2). No significant differences in spore size could be found, but the geographical and subtle morphological patterns correlated to few but significant differences in ITS sequences (1 indel and 2 SNPs), which led us to propose West-European collections at the rank of variety.

Zapata, M.A. Palma, M.J. Aninat & Piont., sp. nov. Etymology. The epithet refers to the rose-coloured aerial mycelia in culture. Classification — Glomerellaceae, Glomerellales, Sordariomycetes. Sexual morph not observed. Asexual morph on synthetic nutrient poor agar (microscopic preparations in 60 % lactic acid, with at least 50 measurements per structure). Vegetative hyphae 1–9.5 μm diam, hyaline, sometimes pale brown, smoothwalled, septate, branched. Chlamydospores not observed. Conidiomata acervular, consisting of conidiophores and setae formed directly on hyphae. Setae abundant, medium brown, smooth-walled, slightly curved or zig-zag-shaped, 0–2-septate, 35 – 90 μm long, base cylindrical, sometimes inflated, 3.5 – 6.5 μm diam at the widest part, tip rounded to acute.

Conidia hyaline, smooth-walled, aseptate, straight, cylindrical to fusiform, with one end round and one end slightly acute, cytoplasm appearing granular, (16 –)18 – 21.5(– 25) × (4 –)5 – 5.5(– 6) μm, mean ± SD = 19.5 ± 1.5 × 5.3 ± 0.3 μm, L/W ratio = 3.7. Appressoria single or in small groups of 2 – 3, medium brown to olive, smooth-walled, clavate, ovate or irregular outline, the edge entire or undulate, sometimes lobate, (6.5–)8–12.5(–16.5) × (4.5–)6–8.5(–9) μm, mean ± SD = 10.5 ± 1.8 × 6.9 ± 0.9 μm, L/W ratio = 1.6.

One strain of C. roseum was collected on the same host and locality to that of Physalospora lapageriae, an older fungus described by Spegazzini (1910) which was later reclassified as Glomerella lapageriae (Petrak & Sydow 1934). However, it proved impossible to compare our asexual fungus with G. lapageriae. Type material of G. lapageriae is deposited at the Museo La Plata (Argentina) and is not currently available for loan to attempt DNA isolation and comparison. Under these circumstances, and considering that C. gloeosporioides, C. godetiae and C. pyricola have also been diagnosed on Copihue by The National Plant Protection Organization in areas close to where C. roseum was found, there is no certainty that G. lapageriae is the same species, and therefore we propose to describe the new strains as a new species. Colletotrichum roseum belongs to the Colletotrichum acutatum species complex (Damm et al. 2012), and is phylogenetically close but clearly distinct from C. kniphofiae. The new species differs from C. kniphofiae by its shorter conidia and characteristic rose-coloured culture. Colletotrichum roseum can be identified with all loci studied, except LSU, with GAPDH and ACT performing best as a diagnostic sequence. Based on a megablast search of NCBIs GenBank nucleotide database restricted to ex-type strains, the closest hit using the GAPDH sequences were C. phormii (GenBank JQ948777, Identities = 238/252 (94.4 %), 3 gaps), C. acerbum (GenBank JQ948790; Identities = 235/252 (93.3 %), 3 gaps) and C. johnstonii (GenBank JQ948775; Identities = 234/252 (92.9 %), 3 gaps).

Etymology. Named after the host, jakajan, cicada in Thai and cola - Latin suffix meaning ‘inhabitant of, residing on’. Classification — Cordycipitaceae, Hypocreales, Sordariomycetes. Stromata pale yellow (blackish brown after drying), simple, fusiform, fleshy, erect, protruding from the ground with several stromata loosely connected emerging from between the head and the thorax of the cicada nymph, 32–45 mm long. Fertile part on the terminal end c. 1/3 of the stroma. Mycelia scarce, whitish, covering the host, slightly rhizoidal in the soil joining together to form a compact stipe upon emerging from the soil. Perithecia semi-immersed, ovoid, 400 – 650 × 300 – 400 μm. Asci cylindrical, 265–360 × 4–5 μm, ascus tip 2–3 μm. Ascospores whole, bola-shaped, 250 – 310 × 1 µm, terminal part fusiform 54 – 60 × 1 μm, central part filiform, < 1 μm diam. Asexual morph Isaria. Synnemata erect and simple with branching near the apex, often clavate, growing from a white to creamy mycelium which covers the host, powdery and floccose near the apex due to heavy conidiation. Conidiophores consisting of verticillate branches with whorls. Phialides 4 – 5.3(– 6) × 2 – 3.5(– 4) μm, consisting of a globose, oval or occasionally conical swollen basal portion tapering suddenly into a thin neck, 0.5 μm wide. Conidia ellipsoid or cylindrical, mostly symmetrical, rarely slightly curved, (4 –)4.5 – 6(–7) × (1.5 –)2 – 2.5(– 3) μm. Culture characteristics — Discharged ascospores germinated within 24–36 h. Colonies had a white to cream funiculose appearance with a cream reverse. Cultures readily produced phialides and conidia after 2 wk on potato dextrose agar at room temperature showing a powdery appearance due to profuse conidiation. From the sexual morph: Colonies on PDA fast growing, attaining 15 – 20 mm diam within 14 d at 25 °C. Colonies floccose, at first white, turning into cream-brown and looking powdery with age. Phialides flask-shaped with long neck, (4 –)5.5– 8(– 9) × (2 –)2.5 – 3.5 μm. Conidia in long chains, cylindrical, (6 –)7– 9(–10) × 2 – 3 μm.

Notes — Cordyceps jakajanicola is parasitic on cicadas that can be found buried in the soil. The macromorphologies of the natural samples of C. jakajanicola closely resemble Cordyceps bifusispora (Eriksson 1982) by producing fusiform, pale yellow ascomata on the terminal part of the stroma. It differs significantly in the host, sizes of the perithecia, asci and ascospores. In C. jakajanicola, perithecia and asci are longer and wider than those reported for C. bifusispora (300 × 150–170 μm; 200 – 220 × 3 – 4.5 μm; 145 – 220 × 4 μm). It shares similarities with C. lepidopterorum (Mongkolsamrit et al. 2018) in phialide and conidial dimensions. In C. lepidopterorum the phialides and conidia are larger (5 – 8 × 4 – 5 μm; 6 –10 × 3 – 4 μm) compared to C. jakajanicola and differs in their respective hosts. The results of our molecular phylogenetic study strongly support and separate C. jakajanicola from other species. Cordyceps jakajanicola is therefore proposed as a new species belonging to Cordyceps.

The phylogenetic tree was analysed using Maximum parsimony (MP), Maximum likelihood (ML) and Bayesian inference. The MP analysis was conducted on the combined dataset using PAUP v. 4.0b10 (Swofford 2003), adopting random addition sequences (100 replications), with gaps being treated as missing data. A bootstrap (BP) analysis was performed using the maximum parsimony criterion in 1 000 replications. The ML analysis was run with RAxML-VI-HPC2 v. 8.2.12 (Stamatakis 2014) under a GTR model, with 1 000 bootstrap replicates. Bayesian phylogenetic inference was calculated with MrBayes v. 3.2.6 (Ronquist & Huelsenbeck 2003), with 5 M generations and under the same model. Numbers at the significant nodes represent MP bootstrap support values/RAxML bootstrap support values/Bayesian posterior probabilities (BPP) times 100.

Notes — Most of the species in Cordyceps have been reported as parasites of insects such as Coleoptera, Hymenoptera, Lepidoptera, and Orthoptera, producing brightly coloured, fleshy stromata. In this study, Cordyceps kuiburiensis is parasitic on spiders (Araneidae) that can be found buried in the soil. This species is only found in PraktaKhoo Waterfall, Kui Buri National Park, Prachuap Khiri Khan Province. The gross macromorpholColour illustrations.

It differs significantly in the sizes of the perithecia and asci. In C. kuiburiensis, perithecia and asci are longer and wider than those reported for C. ninchukispora (95 –145 × 50 – 60 μm; 75 –100 × 2.1– 3.1 μm) by Su & Wang (1986). Additionally, the ascospores in C. kuiburiensis are filiform, while ascospores in C. ninchukispora are whole, bolashaped, with expanded fusoid end parts, and its hosts are lepidopteran pupae, not spiders. The results of our molecular phylogenetic study strongly support and separate C. kuiburiensis from other species. Cordyceps kuiburiensis is therefore proposed as a new species belonging to Cordyceps.

Etymology. Name refers to the conidial ornamentation of the species. Classification — Ajellomycetaceae, Onygenales, Eurotiomycetes. On potato carrot agar (PCA) at 25 °C. Mycelium consisting of branched, septate, hyaline, smooth- and thin-walled 1– 3 µm diam hyphae. Conidiophores unbranched, erect, cylindrical, 12 – 60 × 1– 2 µm, bearing terminal conidia. Conidia solitary, more rarely in chains of 2 – 3, globose to subglobose, hyaline, verrucose to tuberculate, thick-walled, 6 – 9 × 6 – 8 µm. On malt extract agar (MEA) at 37 °C giant cells of 9–22.5 × 9–14.5 µm, and yeast-like cells of 7.5 –11.8 × 7.5 – 9 were observed after 3 wk. Sexual morph absent. Culture characteristics at 25 °C in 3 wk — Colonies on MEA reaching 17.5–19 mm diam, flat, yellowish white (4A2) to yellowish orange (4B7) (Kornerup & Wanscher 1978), velvety, margin lobulated; reverse yellowish orange (4B7); sporulation sparse. On potato dextrose agar (PDA) reaching 35 – 38 mm, felted, greenish white (282A), irregularly sulcate, margin lobulated; reverse dark green (28F7); sporulation sparse. On PCA reaching 44 – 49 mm diam, cottony, white, margin irregular; reverse colourless; sporulation abundant. Cardinal temperatures for growth — Minimum 15 °C, optimum 30 °C, maximum 37 °C. able to produce the yeast morph at 37 °C as in E. terrestris, but with a faster conversion time (3 wk). Besides, our species differs from the other two by its verrucose to tuberculate conidia, the lack of sessile and intercalary conidia, and colonies with a dark green in reverse when growing on PDA at 25 °C. Colony reverse on PDA in E. coralliformis was pale yellow to olive brown and in E. terrestris yellowish white to pale yellow (Marin-Felix et al. 2015). Our phylogenetic reconstruction with the barcodes LSU, ITS and BenA places E. tuberculata in a basal lineage distant from the clade formed by the other species of Emmonsiellopsis. A megablast search in the NCBIs GenBank nucleotide database using LSU sequences showed that E. tuberculata was 98.83 % (675/683) similar with E. terrestris (CBS 273.77; GenBank KT155190.1) and 97.85 % (684/699) with E. coralliformis (CBS 137500; GenBank NG_059238.1), whereas the similarity using ITS sequences was 90.80 % (533/587) with E. terrestris (CBS 273.77; GenBank NR_153965.1) and 92.98 % (503/541) with E. coralliformis (CBS 137500; GenBank NR_153996.1), respectively. BenA sequences showed a similarity of 80.17 % (380/474) between E. tuberculata and E. terrestris (CBS 273.77; GenBank KT155526.1) and of 79.33 % (330/416) between E. tuberculata and E. coralliformis (CBS 137500; GenBank KY710967.1).

Emmonsiellopsis was characterised by producing blastic conidia, borne sessile or on pedicels, smooth, verrucose to spinulose, rarely septate and intercalary, and by the lack of sexual morph and yeast-like phase (Marin-Felix et al. 2015). Later Jiang et al. (2018) demonstrated the ability of Emmonsiellopsis species in producing yeast-like cells after 4 – 5 wk on MEA, namely at 33 °C in E. coralliformis and at 37 °C in E. terrestris.

Etymology. Named after the Tupi-Guarani word for maize, ‘awaxy ’, referring to the substrate (maize ears and stalks) and geographical location (Arapoti and Guarapuava cities in Paraná, as these names come from the Tupi-Guarani language). Classification — Nectriaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes. On synthetic nutrient agar (SNA) with carnation leaves: Microconidia forming abundantly in false heads in aerial mycelium, arising in monophialides and polyphialides, oval, 7.8 –16 µm (x̅ = 11.7 µm) long, 2.1– 5.7 µm (x̅ = 4.4 µm) wide, aseptate. Chlamydospores absent. Sporodochia tan to cream coloured, formed on the surface of carnation leaves and seldom covered with aerial mycelium, occasionally formed on the surface of carnation leaf agar (CLA) or potato dextrose agar (PDA). Macroconidia 3-septate, 24.1– 43.5 µm (x̅ = 30.4 µm) long, 3.2 – 5.1 µm (x̅ = 4.2 µm) wide, less abundant than microconidia, and observed only in sporodochia. Culture characteristics — Colonies on PDA growing in the dark with average radial growth rate of 5.9 mm/d at 24 °C (reaching 74 – 80 mm diam in 7 d at 24 °C), with abundant aerial mycelium. Colony white, pale pink, pale violet or peach, occasionally becoming dark pink, vinaceous or violet in older cultures. Odour absent. Minimum observed temperature for growth at 16 °C, maximum at 32 °C, and optimal at 23 – 28 °C on potato dextrose agar, oatmeal agar and SNA. Typus. braZil, Paraná, Guarapuava, on rotten stalks of Zea mays (Poaceae), 2016, F. Terasawa (holotype UPCB93138-H, cultures ex-type LGMF1930 = CMRP 4013, ITS, LSU, tef1, tub, cal and rpb2 sequences GenBank MH252922, MN566091, MG839004, MG839013, MK766940 and MK766941, MycoBank MB824048). Notes — Fusarium awaxy was identified as a new member from the American clade of the Fusarium fujikuroi species complex in a phylogenetic analysis using tef1, tub, ITS, cal and rpb2 sequences. Fusarium temperatum and F. subglutinans, both species already described causing maize stalk rot (Leslie & Summerell 2006, Scauflaire et al. 2011) are the closest phylogenetic relatives. Fusarium temperatum and F. subglutinans show some morphological similarities, both producing microconidia on mono- and polyphialides arranged in false heads in the aerial mycelium, only differing in the degree of septation of the macroconidia, as F. temperatum macroconidia are usually 4-septate and F. subglutinans are 3-septate (Scauflaire et al. 2011). Besides the difference in sporodochia colour, there is not a clear morphological delimitation between F. awaxy and F. subglutinans. Nevertheless, many other species morphologically similar to F. subglutinans have been described (e.g., F. bulbicola, F. guttiforme, F. sacchari) and can be properly differentiated only with the use of molecular information (Leslie & Summerell 2006). Fusarium subglutinans and F. temperatum have already been described causing human infections (Al-Hatmi et al. 2014), but F. awaxy did not grow above 32 °C, suggesting inability to cause infection in humans. Colour illustrations. Zea mays growing in a field trial near Curitiba. Fusarium awaxy colony on potato dextrose agar plate; sporodochia on carnation leaves; aerial conidiophores: polyphialide, false head and monophialide; aerial oval conidia (microconidia); sporodochial conidia (macroconidia). Photos: D.A.L. Petters-Vandresen. Scale bars = 10 µm. Additionally, based on a BLAST search and a phylogenetic analysis using tef1 sequences, other strains, which were misidentified as F. subglutinans, are now identified as F. awaxy. Such strains include isolates from Zea mays from China (GenBank KT716223; Identities = 630/630 (100 %)) (Zhang et al. 2016), South Korea (GenBank JX867945; Identities = 641/641 (100 %)) (Kim et al. 2012), Argentina (GenBank MG857113; Identities = 641/641 (100 %)) (Martinez et al. unpubl. data) and Brazil (GenBank KP336408; Identities = 545/ 545 (100 %)) (Faria et al. 2012), as well as one strain isolated from Sorghum bicolor in the USA (GenBank KX681493; Identities = 634/634 (100 %)) (Funnell-Harris et al. 2017). Furthermore, another isolate from Zea mays from South Africa (MRC 115, GenBank MH582309; Identities = 649 /649 (100 %)), which was previously identified both as F. subglutinans and also as a putatively novel species (‘Fusarium sp. 8’) (O’Donnell et al. 2018), can now be referred as F. awaxy.

Unexpanded basidiomata epigeous, dark to pale brown (N70Y99M50 to N60Y99M40; Küppers 2002), globose to subglobose, 1.8 – 6.8 × 2.8 –14 mm, surface cottony, spongy, with hyphal tufts forming an areolate pattern, lacking encrusting debris, presence of subiculum white (N00M00C00) little developed covering the substrate, with rhizomorphs adhered to the base. Expanded basidiomata saccate, 5.7–11.2 × 16.5–30.2 mm (including peristome). Exoperidium splitting into 5 – 6 rays, planar to revolute, recurved under the basidiomata, non-hygroscopic. Mycelial layer dark brown (N70Y99M50, N80Y99M50) when fresh, becoming paler (N60Y99M40, N70Y99M40) when dry, not encrusted with debris, persistent, there is no double layer, surface free of incrustations, cottony and persistent in all basidiomata, formed by hyaline hyphae, acuminate-strangled. Fibrous layer light beige (N00Y50M20), papery surface, formed by filamentous hyphae with thin walls, 0.5–1 µm diam. Pseudoparenquimatous layer white ice (N10M00C00), rimose when dried, persistent, consists of brown hyphae, 13 – 50 × 15 – 47 µm. Endoperidial body pale grey (N60Y20M20), globose, 4–10 × 8–21.3 mm, sessile, glabrous surface. Apophysis and pedicel absent. Peristome fibrillose, slightly delimited, up to 1 mm high, mammiform, same colour as endoperidium. Columella circular to columnar, central, yellowish white (N00C00Y10). Mature gleba dark brown (N90Y70M40). Basidiospores globose, brownish in 5 % KOH, 3 – 4 µm diam [av. = 3.4 ± 1.2 × 3.7 ± 0.5 µm, Qm = 1, n = 20], verrucose in SEM, columnar warts, up to 0.5 µm, rounded at apex. Eucapillitium brownish, thin-walled (< 1 µm diam), 2 – 5 µm diam. pseudoparenquimatous layer that is reddish when fresh (Silva et al. 2013a). The other species of the section are morphologically distinguished by: hirsute mycelial layer and peristome not delimited in G. albonigrum (Calonge & Mata 2004); hirsute mycelial layer and larger basidiospores (up to 6.4 µm) in G. inpaense (Cabral et al. 2014); non-delimited peristome and larger basidiospores (up to 7 µm) in G. ishikawae (Crous et al. 2016a); lightly encrusted mycelial layer, orange to pale brown, and larger basidiospores in G. caririense (Crous et al. 2017a); non-delimited peristome, mycelial layer strongly encrusted with debris and sand, and larger basidiospores (5 – 6 µm) in G. rufescens (Sunhede 1989); and non-delimited peristome, developed subiculum and larger basidiospores (4.8 – 5.6 µm) in G. argentinum (Zamora et al. 2014). Geastrum lanuginosum could be morphologically compared to G. javanicum and G. velutinum, although these species cluster in a different phylogenetic section (sect. Myceliostroma subsect. Velutinae). Furthermore, these two species also have a well-developed subiculum, distinct delimited peristome and an ephemeral mycelial layer without strangulated-acuminate hyphae.

Notes — The phylogenetic analysis grouped Geastrum lanuginosum in the section Exareolata (Zamora et al. 2014) with G. aculeatum, G. albonigrum, G. argentinum, G. caririense, G. echinulatum, G. inpaense, G. ishikawae and G. rufensens. All these species have hyphal projections on their exoperidium, as does G. lanuginosum. Morphologically, G. aculeatum and G. echinulatum are similar to G. lanuginosum; however, G. aculeatum has larger basidiospores (5 –7.5 µm diam) and an exoperidium with aculeate hyphal tufts, and G. echinulatum has a well-developed subiculum, non-delimited peristome, and Colour illustrations.

Zamora, Dios, G. Moreno, Hern. Caff. & L.S. Domínguez, sp. nov. Etymology. Named after Jorge E. Wright, Argentinian mycologist who contributed to the study of numerous neotropical gasteroid fungi, including the genus Geastrum. Classification — Geastraceae, Geastrales, Phallomycetidae, Agaricomycetes, Agaricomycotina. Immature basidiomata not seen. Mature basidiomata reaching 4 cm diam and 2.5 cm high (including the peristome). Exoperidium opened in 6 – 9 not truly hygrometric rays, but with tips that may be either involute or curved under the exoperidial disk. Mycelial layer densely encrusting debris, bistratificate, with the external part formed by hyaline to pale yellowish, skeletal hyphae with inconspicuous lumen, and the internal part with hyaline, thin-walled, clamped, generative hyphae, difficult to distinguish. Fibrous layer coriaceous, cream-coloured to brownish, formed by yellowish skeletal hyphae with a ± distinct lumen. Pseudoparenchymatous layer pale cream at first, soon becoming brownish, around 1 mm thick when fresh, less than 0.5 mm thick when dried, slightly thicker towards the stalk, not persistent in old basidiomata, formed by thin-walled inflated cells of variable size and shape, up to about 40 μm wide, smaller towards the fibrous layer. Mesoperidium as a pale cream farinaceous cover over the endoperium in young basidiomata, formed by small calcium oxalate dihydrate crystals (≤ 12 μm diam) and some generative hyphae. Endoperidial body prominently stalked, subglobose-applanate to almost disc-like, up to 1.5 cm diam; endoperidium brown to blackish, glabrous, sometimes with distinct concentric grooves in the upper half and radial grooves in the lower half showing the hyphal arrangement, farinaceous when young due to the mesoperidial cover, formed by brownish skeletal hyphae with distinct lumen. Peristome plicate, 2–4 mm high, with 14–20 folds, conical, not delimited to ± distinctly delimited, dark brown. Apophysis very well developed, ring-like, with a solid and an acute edge. Stalk 2 – 4 mm long, brownish. Columella damaged in the studied sporocarps, but intruding at least 1/2 into the glebal mass. Gleba dark brown to blackish. Capillitium formed by yellowish brown to brownish skeletal hyphae, the broadest about 4 – 5.5 µm diam, thick-walled (up to 2.5 µm thick), with visible lumen, unbranched; surface smooth or sometimes covered with irregular debris. Basidiospores globose to subglobose, 4 – 5(– 5.5) µm diam, verrucose, brownish yellow under the compound microscope. Basidiospore ornamentation under the scanning electron microscope well-defined, up to 0.8 µm in height, irregularly baculate, generally isolated or forming short crests, tending to be radially arranged around the hilar appendix. Habitat & Distribution — Growing solitary to gregarious among vegetal debris, in mixed broadleaf forests. Only known from the Humid Chaco (tropical and subtropical grasslands, savannas and shrublands biome) and the ecotone between the Southern Andean Yungas (tropical and subtropical moist broadleaf forests biome) and the Chaco Serrano (tropical and subtropical dry broadleaf forests biome) (Olson et al. 2001).

Notes — The morphological description is based on nine sporocarps from three specimens, and consequently, we expect a much larger intraspecific variation. Intense surveys were conducted during several years to collect additional samples, but without success, so the species appears to be rare. Geastrum wrightii belongs to G. subsect. Sulcostomata (Zamora et al. 2014), and is macromorphologically very close to G. striatum, sharing the very unusual solid, ring-like apophysis under the endoperidium. Both species can be morphologically distinguished by the basidiospore size and colour, 4–5(–5.5) µm and brownish yellow in G. wrightii, vs 5 – 6(– 6.5) µm and distinctly brown in G. striatum. In addition, the ecology and distribution are different, since confirmed records of G. striatum s.str. are only known from temperate areas of the Northern Hemisphere. One specimen of Geastrum aff. striatum (AH 18521) from Mexico shares the small basidiospore size, but the stalk of the endoperidium is much stouter and shorter, and the apophysis less marked, with a blunt edge, as explained in detail by Zamora et al. (2015). The three studied specimens of G. wrightii form a fully supported clade in our multilocus phylogeny, with both G. striatum s.str. and G. aff. striatum from Mexico being well-separated. The three known species in the G. glaucescens group (G. glaucescens, G. papinuttii and G. parvistriatum) are also clearly distinct based on molecular data of the analysed DNA regions, and are further characterised morphologically by the absence of a sharp ring-like apophysis.

Kiss & Vaghefi, sp. nov. Etymology. Name refers to the genus Glandularia, from which this obligate biotrophic fungus was isolated. Classification — Erysiphaceae, Erysiphales, Leotiomycetes. Mycelium on stems, leaves, and sepals, amphigenous, producing dense, white patches that can cover the aerial host plant surfaces. Hyphae hyaline, thin-walled, 3 – 6 µm wide, with simple, nipple-shaped hyphal appressoria. Conidiophores erect, consisting of a foot-cell, 38 – 95 × 9 –15 μm, basal septum at the branching point or up to 2 – 3 µm displaced, increasing in width from base to top, followed by 1– 4 shorter cells, forming catenescent conidia.

Kiss, BRIP 70531, ITS sequence GenBank MN190243. Notes — Golovinomyces contains approximately 60 species of powdery mildew (Braun & Cook 2012), including many common, widespread, plurivorous taxa (Braun et al. 2019). Amongst these, G. orontii s.lat., G. verbenae and G. spadiceus infect diverse host plant species in the Verbenaceae (Braun & Cook 2012, Braun et al. 2019). Glandularia aristigera is a verbenaceous species native to South America that has been naturalised in parts of Australia. Golovinomyces glandulariae is the first powdery mildew reported on Gl. aristigera globally, causing severe local epidemics in 2017–2019 in Australia. One other species, G. verbenae, has been reported on Gl. phlogiflora (Braun & Cook 2012); other Glandularia spp. are not known as hosts of powdery mildews. Golovinomyces glandulariae differs from G. verbenae by having conidiophores with foot-cells followed by up to four shorter cells, Colour illustrations. A roadside population of Glandularia aristigera heavily infected with powdery mildew in Bunya Mountains, Queensland, Australia. A close-up of an infected plant; conidiophores, non-germinating and germinating conidia, and a hyphal appressorium of Golovinomyces glandulariae. Scale bars = 15 μm (conidiophores, conidia), 5 μm (hyphal appressorium). basal septa sometimes 2 – 3 µm displaced from the point of branching, and smaller conidia. ITS sequences are not available in GenBank for G. verbenae, thus the phylogenetic relationship between these two species cannot be determined. Phylogenetically, G. glandulariae is sister to G. magnicellulatus, which is morphologically similar, although its conidia are larger. As of 26 July 2019, the ITS sequence of G. glandulariae is identical to only two Golovinomyces specimens, KR-M-43410 and KR-M-43411, available in GenBank (acc. nos. LC076839 and LC076840, respectively). These were collected from Verbena in Germany and were recognised as representing a distinct lineage, without being identified at the species level (Scholler et al. 2016). The next closest hits using the ITS sequence of G. glandulariae are 10 G. magnicellulatus specimens with four to six nucleotide position differences in the ITS2 sequences. Most of the powdery mildew mycelium on Gl. aristigera consisted of hyphae, conidiophores and conidia of G. glandulariae, although small patches of Podosphaera xanthii were also found on the aerial plant surfaces. Podosphaera xanthii has conidia with fibrosin bodies, which distinguishes it from G. glandulariae. The ITS sequence of P. xanthii was determined in each specimen (acc. nos. MN190026 – MN190029 and MN190244), and these were all identical to those available in GenBank for over 30 other specimens of P. xanthii collected from diverse host plant species in different parts of the world. This is the first report of P. xanthii on Gl. aristigera globally. It has long been known that the same plants, and even the same leaves may be infected by multiple powdery mildew species (Kiss et al. 2008, Desprez-Loustau et al. 2018) as detected in this study. 77/1.0 98/1.0 -/0.96 100/1.0 100/1.0 100/1.0 100/1.0 Maximum likelihood phylogram based on the internal transcribed spacer sequences of the nuclear ribosomal DNA and the intervening 5.8S region.

Fourn. & A.N. Mill., sp. nov. Etymology. Name refers to the very bristly hairs covering the ascomata. Classification — Helminthosphaeriaceae, Sordariales, Sordariomycetes. Ascomata ovoid, papillate, with an obtusely rounded to slightly conical and cruciform apex, 340 – 380 µm diam, 420 – 550 µm high, numerous, densely clustered, superficial, black, barely emerging from a dense, shiny dark brown subiculum with tufts surrounding the ascomata and projecting above, occasionally covering the ascomata entirely; subiculum hyphae dark reddish brown, slightly sinuous, branched, remotely septate, 5 – 8 µm wide, thick-walled with a lumen, walls 1.5–2.5 µm thick, smoothwalled, with rounded tips. Ascomatal wall of textura angularis in surface view, in longitudinal section 2-layered, 40–55 µm thick, inner layer textura prismatica, 5–10 µm thick, composed of 2–5 layers of elongate, flattened, thin-walled, brown cells, outer layer textura angularis, 35–45 µm thick, composed of several layers of thick-walled, brown cells, cells 4.5 –13.5 µm in their greatest dimension, walls 1.8 – 2 µm thick, with Munk’s pores; tubercles composed of clusters of subglobose cells, 6 – 9 µm diam, walls up to 3.5 µm thick, bearing long hyphal hairs indistinguishable from the subiculum hyphae. Ascomatal apex composed of a palisade of thick-walled, rectangular cells converging around the ostiole and terminating as small, opaque cells on the surface, with periphyses arising from an inner hyaline basal layer. Paraphyses filiform, 1.5 – 2.5 µm wide, embedded in a dense mucilaginous matrix, hyaline, sparse, remotely septate, unbranched, persistent. Asci broadly fusiform, 78 – 90 × 13.5 –18 µm, stipitate, stipe 34 – 56 µm, unitunicate, thin-walled, apex truncate; ring narrow, 0.6 – 0.8 × 3 – 3.5 µm, shallow, refractive, I-, faintly stained by blue and blue-black inks; with 8 bi- to triseriate ascospores. Ascospores cylindrical, allantoid, with obtuse ends, (17.5 –)18.5 – 23(– 24) × (4.5 –)5 – 6(– 6.5) µm (av. 21.2 × 5.7), yellowish and aseptate in the ascus before maturity, eventually light to yellow brown and 1-septate, septum medial, thick, blackish brown, not constricted; with large and small guttules, smooth-walled, without sheath or appendages.

Fournier & C. Lechat, MJF 13262 = ILLS00121146. Notes — Helminthosphaeria hispidissima at first appears to resemble Lasiosphaeris hirsuta since they share tuberculate, hairy ascomata (Miller & Huhndorf 2004). However, their ascospores differ greatly being allantoid and lacking appendages in H. hispidissima and vermiform with awl-like appendages in L. hirsuta. Six other species in the Helminthosphaeriaceae possess allantoid to cylindrical and curved ascospores ranging in shape and septation from short, fat and aseptate in H. stuppea and H. tomaculum to longer, narrower and up to 1-septate in Echinosphaeria canescens and Ruzenia spermoides to long, narrow and 1–5-septate in E. heterostoma and Hilberina punctata (Miller et al. 2014). Helminthosphaeria hispidissima is easily distinguished by its brown, 1-septate ascospores, whereas the other six species possess hyaline to pale brown (or brown, but much longer ascospores in E. heterostoma), aseptate or multiseptate (rarely 1-septate) ascospores. 94 64 Echinosphaeria canescens KF765605 Echinosphaeria canescens AY436404 Helminthosphaeria cf. stuppea KF765611 100 100 Ruzenia spermoides KF765618 Ruzenia spermoides AY436421 100 71 Hilberina punctata MN447130 Helminthosphaeria hispidissima MN447129 Heminthosphaeria tomaculum KF765613 Melanochaeta hemipsila AY346292 0.05 Chaetosphaeria ovoidea AF064641 Maximum likelihood tree generated using PhyML in SeaView v. 4.5.4 (Gouy et al. 2010).

Typus. braZil, Minas Gerais, Viçosa, campus of the Universidade Federal de Viçosa, coffee experimental area (Viveiro de Café), on living leaves of Mikania micrantha (Asteraceae), 4 Dec. 2018, R.W. Barreto (holotype VIC 47212, ITS and LSU sequences GenBank MN537723 and MN537725, MycoBank MB832760). Phylogenetic trees constructed from the analysis of Maximum Parsimony and Bayesian Inference demonstrated that the fungus belongs to the Chaetothyriaceae. Many species included in this family are epiphytes, colonising the surface of living leaves with mycelium limited to the host cuticle (Chomnunti et al. 2012). Sequences of the fungus, obtained directly from colonies on living leaves of M. micrantha, formed a clade isolated from other genera of Chaetothyriacae, with high support (bootstrap = 100 / posterior probability = 1) justifying the recognition of a new monotypic genus for this species. The closest genera to Hermetothecium in the phylogenetic study are Phaeosaccardinula and Vonarxia. Fungi in Phaeosaccardinula have ascomata, with a dark, non-setose pellicle, saccate, bitunicate asci and muriform, hyaline to brownish ascospores (Yang et al. 2014). Vonarxia is based on an asexual morph which is sporodochial, with septate setae (Batista et al. 1960). Notes — Numerous attempts to isolate this fungus on a range of general-purpose culture media failed to produce any culture, leading to the conclusion that this is a biotrophic taxon. Furthermore, detailed observations under the compound microscope and via scanning electron microscopy failed to produce any evidence of appressoria, or other penetration structures of leaf tissue, or any internal growth of mycelium. It appears that H. mikaniae-micranthae is an epiphyte relying strictly on plant exudates for its growth and is a specialised colonist of this plant host. Mikania micrantha is a relatively uncommon but widespread ruderal climber in Brazil, frequently associated with marshy areas. However, in its exotic range in the Palaeotropics, especially in Asia, it is highly invasive and damaging (milea-minute weed) in both natural and agricultural ecosystems (Ellison & Sankaran 2017).

Etymology. Refers to the island where the species was found. Classification — Russulaceae, Russulales, Agaricomycetes. Pileus 56 mm diam, planoconvex with depressed centre; margin straight; surface minutely pubescent, wrinkled near the margin, dry, light drab fading to drab grey. Stipe 21 × 8–12 mm, regular and cylindrical, slightly tapering downwards, stuffed; surface smooth, dry, white. Lamellae adnate, some forked near stipe, some crisped, subdistant, more than 1 mm apart halfway the radius, with abundant lamellulae in a regular shortlong-short pattern (3 –7 between two lamellae), cream to pale horn, staining slowly raw sienna; edge concolorous and entire. Context white, brown at the base and in the centre, rapidly turning cinnamon when cut. Smell slightly foetid, like rotting meat. Taste sweet, very slowly faint acrid. Latex white, staining brown. Basidiospores broadly ellipsoid to ellipsoid, (7.3 –) 7.5 –9.5 –11.4(–11.7) × 6 –7.2– 8.4 µm (Q = 1.15–1.32 –1.49); ornamentation amyloid, composed of isolated warts, up to 1 µm high; plage distinct and often weakly centrally to distally amyloid. Basidia 52.5 – 62.5 –72.5 × 9.5 –12 –14(–14.5) µm, subclavate, 4-spored. Pleurocystidia absent. Pseudocystidia inconspicuous, 6.5– 8 µm wide, not emergent. Lamellar edge fertile. Hymenophoral trama mixed, with sphaerocytes, hyphae and abundant lactifers. Pileipellis a dense lamprotrichoderm; terminal elements 22.5–70–117 × 2–3–4 µm, cylindrical, rarely subcapitate, thick-walled, often refringent; subpellis composed of thick-walled interwoven hyphae. Stipitipellis as pileipellis. Distribution — So far only known from the type locality, the North Bay woods on Guana Island. Occurring on sandy soil under Coccoloba uvifera. There is only one other Lactifluus species known from the Greater Antilles or associated with Coccolobo uvifera. Lactarius coccolobae* closely resembles Lactifluus guanensis. However, L. coccolobae has more narrow basidia (8 – 9.5 µm wide), slightly shorter spores (7.2 – 9(–10.8) µm long), lower spore ornamentation (up to 0.3 µm) and a gelatinised pileipellis (Miller et al. 2000). On the other hand, Lactifluus guanensis is easily distinguishable from Lactifluus species from the Lesser Antilles, notably due to the often amyloid plage, the absence of macrocystidia and the lamprotrichoderm structure of the pileipellis consisting of thick-walled elements. Only L. caribaeus also lacks macrocystidia and has a trichodermial pileipellis, but differs by the distinctly smaller and more globose spores (6.6 –7.6– 8.5 × 5.8– 6.3– 6.8 µm (Q = 1.06–1.20 –1.35)) with inamyloid plage, and by the thin-walled terminal elements of the pileipellis. Typus. britiSh Virgin iSleS, Guana Island, North Bay woods, N18°28'42" W64°34', 24 Oct. 1997, D.J. Lodge (holotype GUA-104 (CFMR), ITS sequence GenBank MK046851, MycoBank MB831225). Notes — Lactifluus guanensis belongs to L. subg. Gymnocarpi, which is supported by molecular data (ITS phylogeny: see Supplementary Fig. FP1018), as well as by morphological characters, such as the absence of true pleurolamprocystidia and a brownish colour reaction of the latex and/or the context when exposed to air. Lactifluus guanensis is part of an unnamed section (Clade 1; Clade 9 in De Crop et al. 2017), a section which contains exclusively Neotropical species, mostly species from the Antilles. Morphologically this species has similar characters to the other species in this section (e.g., L. murinipes, L. nebulosus, L. putidus), such as dull basidiocarp colours, brown staining of the latex and context, unpleasant smell and spore ornamentation consisting of isolated warts.

Alvarado, sp. nov. Etymology. The epithet refers to the place where it was found (Illa de Cortegada, Parque Nacional Marítimo-Terrestre de las Islas Atlánticas, Galicia, Spain). Classification — Mollisiaceae, Helotiales, Leotiomycetes. Apothecia gregarious, from 0.5 – 4 mm diam, first slightly concave and then flattened, irregularly disc-shaped, umbilicated or depressed, sessile, centrally attached to the substrate. Hymenium smooth, wavy, gibbous, yellowish grey when fresh and orange-ochre when dry, with the external and central parts dark grey. Asci cylindrical-clavate 80 –120 × 12 –18 μm, 8-spored, with a conical apex and a base gradually narrowed into a medium-sized stalk with croziers, showing no reaction to IKI (Lugol’s solution), and turning only slightly yellowish in KOH (no ionomidotic reaction). Paraphyses distinctly dimorphic, either cylindrical, inflated (molliform), or slightly broadened at the apex, with refractive vacuolar bodies at the top. In addition, the paraphyses extend beyond the asci. Ascospores elliptical with rounded ends, measuring 15 –18 × 5.5 –7 μm, with 1– 2 small (< 1 μm) guttules at the poles. Ectal excipulum consisting of a brownish texture globose at the base, and globose elements in the surface. The margin lacks conspicuous protruding cells. The medullary tissue consists of gelatinized hyphae. Subicular hyphae sparse, hyaline and thick-walled. All observations made on fresh specimens. Distribution — Currently known only from the type location in north-western Spain. Phylogeny — The analysis of ITS and 28S rDNA suggests that the sample from Cortegada is related with the monophyletic Vibrissea-Loramyces clade (Wang et al. 2006, Hustad & Miller 2011, Han et al. 2014) of the Mollisiaceae s.lat. According to the family concepts proposed by Johnston et al. (2019), M. cortegadensis belongs to the clade of families Mollisiaceae, Loramycetaceae and Vibrisseaceae, which could be merged into the oldest name Mollisiaceae. 8 –14 × 2.8– 3.5 µm, but those of M. cortegadensis can be as long as 18 µm. In addition, M. cortegadensis is drought-tolerant and growing in clusters in the apical part of small decorticated branches of Quercus robur, while M. spectabilis grows on rotten leaves of Q. robur or underneath rotten Quercus logs (Kirschstein 1938). Other species similar to M. spectabilis such as M. elegantior and M. olivascens can be found in the same locality, but they have different spore dimensions and lack the orange ochre tones when dry (Richter & Baral 2008, Le Gal & Mangenot 1958). The putative phylogenetic relationship with M. ligni and M. minutella is only supported by a few shared ecological or morphological trait, since M. ligni has ascospores 6 –10 × 2 – 3 µm, cylindrical paraphyses with low refractive vacuoles (Karsten 1873) and M. minutella, which is sometimes considered a synonym of M. cinerea, has ascospores 7–14 × 2.5 – 3 µm and the apices of asci stain blue in IKI (Karsten 1871).

Notes — Ophiocordyceps khonkaenensis produces ascomata on the terminal part of the stroma. Their hosts are cicada nymphs that can be found buried in soil. This species was only found in Khon Kaen Field Crops Research Center, Khon Kaen Province during the rainy season. It is nested in a clade together with O. longissima and O. sobolifera (Sung et al. 2007). It shares similarity with O. longissima in the colour of the fertile part. However, in O. longissima and also in O. sobolifera, the shape of the fertile part is clavate with a pointed end. Ophiocordyceps khonkaenensis produces broadly ellipsoidal fertile heads and ovoid perithecia but in O. sobolifera the fertile head is cream, not red, and the perithecia are stouter (500 – 600 × 220–260) compared to O. khonkaenensis. It shares similarities with O. heteropoda in the ovoid shape of the fertile area (Sung et al. 2007). However, it differs in the colour of the fertile head, which is mustard yellow to dark brown in O. heteropoda, and the perithecia are ampullaceous, completely immersed, 610 – 660 µm long, around 210 µm wide. Etymology. Named after the location where the species was collected, Khon Kaen Province, Thailand. Classification — Ophiocordycipitaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes. Stromata variable in number, solitary to three, 20–30 mm tall and 2–3 mm wide. Rhizoids flexuous, c. 2 cm long, arising from the head of cicada nymphs living underground. Fertile part distinctly terminal, globose, pinkish red, sterile stroma beneath the fertile part cylindrical, pale pink. Ascomata perithecial, completely immersed, ovoid, (590–)615–675(–700) × (200–)216–263(–300) µm. Asci cylindrical, (237.5–)252–326(–337.5) × 5–5.8(–6) µm with cap, 5 × 5 µm. Ascospores filiform, (300–)314–353(–360) × 1.5–2 µm readily breaking into 32 part-spores, (7–)9–11.5(–13) × 1.5–2 µm. Culture characteristics — Colonies developed from germinating ascospores. The ascospores germinated within 24 h on potato dextrose agar (PDA). Colonies relatively slow-growing, attaining a diameter of 5 mm in 30 d at 25 °C, dark brown with cream edges. Colonies produce brown synnemata after 1 mo with a pruinose area bearing conidiogenous cells and conidia. Conidiogenous cells phialidic, hirsutella-like, (5.5 –) 6.4 – 8.6 (–11) × 2 – 2.7(– 3) µm. Conidia hyaline, fusiform, smoothwalled, (3 –)3.7– 4.9(– 5.5) × (1–)1.5 – 2.3(– 3) µm.

Phylogenetic reconstruction using the Maximum Parsimony (MP) and Maxi-mum Likelihood (ML) (RAxML v. 8.2.10, Stamatakis 2006) multilocus phylogenetic analyses based on nuclear ribosomal small and large subunits (SSU and LSU), the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2) and elongation factor 1-α (TEF) revealed that Ophiocordyceps khonkaenensis is closely related to O. sobolifera and O. longissima. Molecular data of these specimens formed a separate clade from other species of Ophiocordyceps with full bootstrap support (100 %), thus a new species Ophiocordyceps khonkaenensis is introduced.

All four genes distinguish these species. Morphologically, P. lunae is the only of the three that can grow on CYA at 37 °C. Compared to P. chermesinum and P. indicum, the new species generally shows more restricted growth (especially on CYA) (Pitt 1980, Peterson et al. 2005). Microscopically they are very similar except for P. cuddlyae and P. lunae producing longer phialides (up to 10 μm vs 7–8 μm) (Pitt 1980). Penicillium cuddlyae produces ellipsoid conidia compared to the subglobose to broadly ellipsoid conidia of P. lunae.

Notes — Penicillium reconvexovelosoi is phylogenetically related to P. mellis (Barbosa et al. 2018), both included in the section Sclerotiora. Penicillium mellis grows faster than P. reconvexovelosoi on CYA 30 °C (33 – 35 mm) and YES (34 – 36) and grows slower on OA (24 –25), DG18 (24 – 25) and CREA (10 –11). Penicillium reconvexovelosoi does not grow on CYA 37 °C, but P. mellis grows (2 – 4 mm). Penicillium reconvexovelosoi may produce a soluble light brown pigment on CYA and weak acid production on CREA, but P. mellis does not produce soluble pigments in CYA and neither acid on CREA. Penicillium reconvexovelosoi has longer stipes than P. mellis (25 – 40 × 2 – 3.5 μm) and produces mycelial coils, but these structures were not reported for P. mellis. All macroscopic and microscopic measurements were done twice, independently, for isolate CCDCA 11500.

Malysheva & Malysheva, sp. nov. Etymology. The epithet reflects very small, diminutive size of basidiocarps. Classification — Pluteaceae, Agaricales, Agaricomycetes. Basidiocarp tiny. Pileus 9 mm diam, infundibular with concave centre; margin serrated, not striated, slightly undulating; not hygrophanous; surface squamulose, covered with small erect dark brown squamules, densely located at centre and scarce towards margin with white context exhibited between them, and the pattern of the squamules arrangement gives the impression of mottle. Lamellae free, fairly distant, ventricose, white becoming pink, with serrulated, concolorous edges. Stipe 10 × 1–1.5 mm, cylindrical, somewhat broadening towards base, but without basal bulb, whitish or with light ochraceous shades, slightly pruinose. Context in pileus and stipe white. Smell and taste not distinctive. Basidiospores 5.3 –6.2 × 5 –5.8 µm (Lav = 5.7, Wav = 5.3), Q = 1.00 –1.16, Q* = 1.08, globose to subglobose; thick-walled; hyaline in KOH, with one large or numerous small guttules. Basidia 19 – 33 × 7.5 – 8.5 µm, 4-spored, broadly clavate with a medial constriction at maturity. Cheilocystidia rather numerous to abundant, forming sterile layer at the lamella edge, 36–83 × 9–15 µm, mainly clavate or narrowly utriform, rare almost cylindrical, pedicellate (with short to long pedicels), most of them with slimy apical caps or apical drops; slightly thickwalled; hyaline. Pleurocystidia absent. Pileipellis a cutis, made up of ascending bundles of narrowly fusiform or cylindrical thickwalled elements, with intracellular brown pigment, 70–170 × 10–14 µm. Stipitipellis a cutis, made up of long, cylindrical, hyaline hyphae, 4 –10 µm wide. Caulocystidia absent. Clamp connections absent in all parts examined. Habitat & Distribution — Solitary, on fallen branch of deciduous tree, in mixed coniferous-broadleaf forest. So far known only from type locality. Notes — Pluteus liliputianus is characterised by tiny basidiocarps, squamulose dark brown pileus with a peculiar arrangement pattern of squamules, pileipellis organised as a trichoderm with long fusiform terminal elements, absence of pleuro- and caulocystidia, and globose or subglobose basidiospores. Based on its pileipellis structure P. liliputianus is placed in sect. Celluloderma. This new species resembles P. hispidulus, P. exiguus, P. karstedtiae, P. hispidulopsis and P. spurius by its macroscopic features but can be distinguished from them due to microscopic characters. Pluteus liliputianus can be distinguished from the first three species listed mainly by the cheilocystidia shape, as well as shape and size of basidiospores (Vellinga 1990). It differs from P. karstedtiae by having a smaller basidiocarp, differently coloured pileus with more distinct squamation and non-striate margin, larger cheilocystidia, and the pileipellis structure (Menolli et al. 2015). Pluteus hispidulopsis is distinguished by the structure of its pileus surface and colouration, smaller basidiospores (5–5.5 × 4.5–5.5 µm), the presence of pleurocystidia and the pileipellis organised as a cutis (Menolli et al. 2015). Pluteus spurius, another species distributed in the same territory and described herein, is characterised by larger basidiocarps, differently shaped cheilocystidia, pileipellis a cutis, and the presence of caulocystidia. In the phylogenetic analyses, the sequence of P. liliputianus forms an individual branch which is placed close to the group of P. hispidulus.

Malysheva & Malysheva, sp. nov. Etymology. Name reflects the similarity of the newly described species with a group of closely related taxa and the possibility of confusion when definition is based only on macroscopic features. Classification — Pluteaceae, Agaricales, Agaricomycetes. Basidiocarp small. Pileus 10–18 mm diam, at first hemispherical, later applanate and becoming concave, without umbo; margin even, not striated, slightly undulating; not hygrophanous; surface fibrillose-squamulose, covered with small greyish brown or ash brown squamules, densely located at centre, and adpressed fibrils becoming sparse towards margin with white context exhibited between them. Lamellae free, fairly distant, ventricose, white becoming pink, with serrulated, concolorous edges. Stipe 15‒25 × 1‒2.5 mm, cylindrical, somewhat broadening towards base, but without basal bulb, whitish or with light ochraceous shades, slightly pruinose and longitudinally fibrillose. Context in pileus and stipe white. Smell and taste not distinctive. Basidiospores (5.2 –)5.5 –6.5(–7) × (4.8–)5– 5.6(– 6.4) µm (Lav = 5.9, Wav = 5.3), Q = 1.00 –1.22, Q* = 1.10, globose to subglobose; thick-walled; hyaline in KOH, with one large or numerous small guttules. Basidia 20 –35 × 7–8.5 µm, 4-spored, broadly clavate with a medial constriction at maturity. Cheilocystidia rather numerous to abundant, forming sterile layer at the lamella edge, 30 ‒54 × 9.5 ‒15(–17) µm, mainly lageniform, inflated-lageniform or fusiform, rarely utriform or clavate, with short pedicels and often with subglobose apex; thin-walled; hyaline. Pleurocystidia absent. Pileipellis a cutis, made up of slightly thick-walled hyphae, 10–12 µm wide, with intracellular brown pigment; transforming into a trichoderm at centre of pileus, with bundles of fusiform, usually septate, terminal elements more than 100 µm long and 12 ‒22 µm wide. Stipitipellis a cutis, made up of long, cylindrical, hyaline hyphae, 4–8 µm wide. Caulocystidia present in all parts of stipe, scarce, in bundles, cylindrical or fusiform, 50 ‒120 × 8‒10(–14) µm; thin- or slightly thick-walled; hyaline. Clamp connections absent in all parts examined. Habitat & Distribution — Solitary, on decaying deciduous wood or soil, in floodplain broadleaf or mixed coniferous-broadleaf forests. Known from two localities in the Russian Far East. Typus. ruSSia, Primorye Territory, Kedrovaya Pad’ Biosphere Nature Reserve, floodplain of Kedrovaya River, broadleaf forest, on decaying wood of deciduous tree, 4 Sept. 2011, V. Malysheva (holotype LE 312866; ITS and LSU sequences GenBank MK982290 and MK982303, MycoBank MB831299). Additional material examined. ruSSia, Primorye Territory, vicinities of Vladivostok, Ocean Ridge, mixed coniferous-broadleaf forest (Abies holophylla, Pinus koraiensis, Juglans mandshurica, Acer spp.), on soil, 9 Sept. 2013, E. Malysheva (LE 312869, ITS and LSU sequences GenBank MK982289 and MK982302). Notes — Pluteus spurius is characterised by small-sized basidiocarps, with greyish brown coloured and fibrillose-squamulose pileus, serrulated edges of lamellae, pileipellis as a cutis with long fusiform terminal elements, absence of pleurocystidia, numerous caulocystidia, and globose or subglobose basidiospores. Based on its pileipellis structure P. spurius is placed in sect. Celluloderma. Pluteus spurius is morphologically close to P. hispidulus var. hispidulus, P. hispidulus var. cephalocystis, P. exiguus, P. karstedtiae and P. hispidulopsis in terms of basidiocarp size, squamulose pileus of similar colouration, and pileipellis structure, but can be distinguished from them due to other microscopic features (for detailed discussion: see Additional data below). The molecular data (generated nrITS sequences) confirmed the morphological differences between all species discussed and supported the recognition of Pluteus spurius as a separate taxon (see phylogenetic tree on the page with Pluteus liliputianus description = FP1023). Additional data Colour illustrations. Russia, Kedrovaya Pad’ Biosphere Nature Reserve. Basidiocarp; basidiospores; pileipellis; cheilocystidia; basidia (all from holotype). Scale bars = 5 mm (basidiocarp), 10 µm (microscopic structures). Pluteus spurius can be distinguished from P. hispidulus var. hispidulus by the cheilocystidia shape, slightly smaller (vs (5.2–) 6 –8(–8.5) × (4–)5 –6 µm), globose or subglobose basidiospores and the presence of caulocystidia (Vellinga 1990). Pluteus hispidulus var. cephalocystis differs by ellipsoid basidiospores (Vellinga 1990) and the absence of caulocystidia (Malysheva et al. 2016). Pluteus exiguus differs in the shape of cheilocystidia, ellipsoid or slightly amygdaliform basidiospores, and pileipellis organized as a trichoderm (Vellinga 1990). Pluteus karstedtiae is distinguished by sulcate-striate margin of pileus, rare cheilocystidia of slightly different shape, and the absence of caulocystidia (Menolli et al. 2015). In the phylogenetic analyses, the sequences of P. karstedtiae, including one from the holotype, form a sister clade to Pluteus spurius. Pluteus hispidulopsis differs in the fringed margin of pileus, smaller basidiospores (5 –5.5 × 4.5 –5.5 µm), the presence of pleurocystidia, differently shaped cheilocystidia and the absence of caulocystidia (Menolli et al. 2015).

Deschuyteneer, Heykoop & G. Moreno, sp. nov. Etymology. Name reflects the unusual morphology of its spores. Classification — Psathyrellaceae, Agaricales, Agaricomycetes. Cap 9 – 23 mm broad and 6 –13 mm high, convex to conical convex, flattened convex at maturity, with umbo, ochre-brown, hygrophanous, striate when moist, first drying at the margin that adopts a beige straw colour, leaving the central area with a darker ochre colour, finally light beige ochre colour. Veil fugacious, consisting of white appressed fibrils at margin of pileus, connecting the upper part of stipe, soon evanescent, leaving remnants on the edge of some gills near the stipe. Gills subventricose, adnate, more or less dark blackish greyish coloured, with white edge, but coloured brown in its half near the margin of the cap; lamellulae present. Stem 30–50 × 1.5–3 mm, cylindrical, slightly widened at the base, white to whitish, some with pale creamy ochre tones especially in the lower two thirds. Odour not distinctive. Spores (9.6 –)10.3 –12.3(–13.3) × (5.9 –)6.3 –7.8(– 8.1) µm, av. 10.9 –11.6 × 6.7–7.1; Qav 1.6, ellipsoid and ovoid in frontal view and even a little rounded, asymmetric and amygdaliform in side-view, smooth, germ pore distinct, central, 1–1.5 µm, hilar appendix very tiny, base sometimes truncate giving a subtriangular look in frontal view, dark brown, not opaque, very granular, containing most often one large oil drop. Basidia 4-spored, rarely 2-spored, (21.9–)23.4– 29.4(– 31) × (10.2 –)11.6 –13.5(–15.1) µm, av. 26.5 × 12.6 µm, clavate, hyaline with intracellular content. Pleurocystidia (39.5–)43.7–66.7(–77.3) × (9.5–)10.4–17.4(–19.4) µm, numerous, mostly lageniform with a long neck, some of them shorter (sub)utriform, ventricose or clavate, apex obtuse, very rarely forked, most often widely pedicellate, always thin-walled, hyaline, some of them covered with mucoid droplets or granular deposits which gradually disappear in exsiccate. The importance of these deposits will have to be reassessed after examination of new fresh specimens. Cheilocystidia (23.6–)30.6–43(–55) × (8.2–)9.3–12.4(–14.1) µm, very numerous and densely packed, hyaline, sublageniform, ventricose, clavate, subutriform, often polymorphic, always thin-walled, apex obtuse, sometimes subcapitate, rarely forked. At the half of the lamella-edge close to the cap margin thin-walled cheilocystidia become scattered, fewer in number, intermixed with many clavate marginal cells (= paracystidia), some of them thick-walled and brown coloured. Veil fibrillose, consisting of elongated and septate hyaline hyphae with inflated endings. Clamp connections present. Habitat & Distribution — Gregarious on nitrified calcareous loamy soil among grasses under Conium maculatum, Foeniculum vulgare with Urtica urens. So far only known from Spain and Hungary. Typus. Spain, Madrid, Alcalá de Henares, El Gurugú, on nitrified calcareous loamy soil, among grass with Conium maculatum and Urtica urens, 2 Dec. 2016, G. Moreno & M. Heykoop (holotype AH 33724, ITS and LSU sequences GenBank MF966497 and MN190260, MycoBank MB832058). Notes — Psathyrella ovispora is characterised by the unusual if not unique appearance of its spores which vary from ellipsoid to ovoid, with base sometimes truncate giving a subtriangular look in frontal view, asymmetric and amygdaliform in side-view, containing most often one large oil drop. Other characters are the small to medium sized basidiomata and its gregarious fruiting on calcareous nitrified soils. Psathyrella ovispora was erroneously identified by us as P. fusca (Heykoop et al. 2017). A morphological re-evaluation of our material, comparing it with abundant samples of P. tephrophylla (= P. fusca), has showed that it corresponds to a new species. Moreover, our former cladogram (Heykoop et al. 2017), due to poor sampling, showed a unique P. fusca clade. However, new sequences of P. tephrophylla generated a cladogram (see Supplementary Fig. FP1025-2) in which two very distinct clades can be differentiated, i.e., P. tephrophylla clade A corresponding to P. tephrophylla s.str., and P. tephrophylla clade B corresponding to P. ovispora. The material included by Nagy et al. (2011) in their study as P. fusca is conspecific with P. ovispora. The commonly used name Psathyrella fusca (Schumach.) A. Pearson is illegitimate, and must be rejected, since its basionym Agaricus fuscus Schumach. 1803 is a later homonym of A. fuscus Schaeff. 1774, A. fuscus Batsch 1783 and many others. Therefore, the correct name for Psathyrella fusca s.str. is P. tephrophylla. This nomenclatural problem will be discussed by one of us (Deschuyteneer) in a future paper. Psathyrella ovispora shares with P. tephrophylla similar cheilocystidia and pleurocystidia. However, it differs from the latter by its very different spores, the much smaller basidiomata, by fruiting in a different habitat and by being genetically different. Due to its very wide spores P. ovispora keys out (key B) as P. magnispora in Örstadius et al. (2015). Psathyrella ovispora, however, differs from P. magnispora by its slightly larger basidiomata, the differently shaped spores and cystidia. Besides, P. magnispora is completely different genetically and constitutes the very distinct and monospecific magnispora clade, whereas P. ovispora belongs to the pygmaea clade (Örstadius et al. 2015) Supplementary material FP1025-1 Additional specimens examined.

Moreno & M. Mata, sp. nov. Etymology. Named for Dr Alfio Piva, former Director of the INBio and ex vice-president of the Republic of Costa Rica, recognising his contribution to the conservation of biodiversity. Notes — Psathyrella pivae is characterised by its fibrillose ring, abundant and very long thick-walled pleurocystidia and by growing caespitose on woody debris. Classification — Psathyrellaceae, Agaricales, Agaricomycetes. In our ITS phylogeny (see below) Psathyrella pivae belongs to the pygmaea clade (Örstadius et al. 2015) in which it is significantly related to P. olympiana. Within this monophyletic assemblage P. pivae forms a subclade together with P. pygmaea, P. cloverae and P. olympiana, all of them sharing the presence of more or less thick-walled pleuro- and cheilocystidia, apically covered with a crown of crystals and/or crystalline granular material. This clade has been included by Kits van Waveren (1985) in sect. Spadiceae. However, according to Larsson & Örstadius (2008), Vasutová et al. (2008), Nagy et al. (2013) and Örstadius et al. (2015), sect. Spadiceae turned out to be a polyphyletic taxon including species from two different genera, viz. Psathyrella and Homophron, since the presence of muricate pleurocystidia evolved independently at least in three different clades. Cap 30 – 35 mm broad, applanate to slightly convex, surface fibrillose with appressed fibrils, coffee milky brown coloured. Margin deflexed, hygrophanous, striate when moist. Context of pileus 1 mm thick, 2 mm at centre, concolorous to surface. Veil forming a fibrillose annulus in the upper half of the stipe. Gills up to 5 mm broad, (sub)ventricose, adnate, smooth, coffee brown coloured, lamella-edge white; lamellulae present. Stem 50 – 55 × 4 mm, cylindrical, central, equal, some of them curved, hollow, fibrillose, yellow coffee coloured in the upper part, whitish in the lower part, with some dark brown fibrils at the apex and equipped with a fibrillose ring. Odour and taste not recorded. Spores (8.5 –)9.5 –11 × 5 – 6 µm, av. 9.9 × 5.5 (one collection); Qav 1.79, ellipsoid to phaseoliform, smooth, with small apical germ pore (difficult to see), in NH4OH (10 %) pale brown to orange brown. Basidia 4-spored, 22 – 30 × 9 µm, clavate, hyaline. Pleurocystidia 68 – 90(–100) × 15 – 27 µm, numerous, lageniform to ventricose-fusoid or fusiform, most of them with wall thickened 1–1.5 µm along entire length, often thickest at apex (up to 4 µm), yellowish refractive, very few thinwalled; apex of most cells encrusted with a cap of crystals and/ or crystalline granular material. Cheilocystidia 38 – 50 × 12 –14 µm, very abundant, lageniform to fusoid-ventricose, fusiform or even utriform, with walls thickened but thinner than those of pleurocystidia (rarely thin-walled), yellowish refractive, some of them colourless. Hymenophoral trama in NH4OH (10 %) consisting of hyaline thin-walled hyphae, 2 – 5 µm diam, without encrustations. Clamp connections present. Habitat & Distribution — Caespitose on woody debris.

Basidiomata; cystidia and spores under LM and SEM (all from the holotype). Scale bars = 1 cm (basidiomata), 10 μm (microscopic elements under LM), 5 µm (cystidia under SEM), 2 μm (spores under SEM). Because of the muricate pleurocystidia and the presence of veil Psathyrella pivae keys out in Kits van Waveren’s monograph (1985) close to P. olympiana. Psathyrella pivae, however, differs from P. olympiana genetically and by the presence of a fibrillose annulus, larger spores and much longer pleurocystidia (up to 100 µm in length). Psathyrella pivae is a species with abundant fibrillose veil recalling macroscopically a Stropharia species, and as such it was tentatively identified in the field. Kits van Waveren (1985) included in his monograph P. olympiana f. amstelodamensis, characterised by its strongly developed veil but mentioning “in all other respects this form is identical with P. olympiana”. Moreover, the illustrations of his f. amstelodamensis do not show any annulus on the stipe.

Etymology. Named after Daniel Lindner from the United States Forest Service for his significant contributions to the modern taxonomy of Pseudogymnoascus and his contributions to White-nose Syndrome research. Classification — Pseudeurotiaceae, incertae sedis, Leotiomycetes. On Sabouraud dextrose acidified with 120 µL 85 % lactic acid for optimal pigment production: Conidia borne singly at the tips, globose to obovate, smooth, with one abscission scar 2.8 – 4.1 (3.5, n = 30) µm in length. Intercalary conidia with two abscission scars, globose to truncate, measuring 3 – 4 (3.5, n = 10) µm in length. On oatmeal salt sediment agar: Ascomata gymnothecial, solitary, globose, measuring 181– 311 (220, n = 20) µm diam; greyish orange (5B6; Kornerup & Wanscher 1978); developing rapidly and ripening within 10 d at 25 °C (12 h white fluorescent light / 12 h dark). Ascomatal initials coiled to irregular; peridium is a gymnothecium composed of textura intricata, the peridial hyphae darkly pigmented brownish yellow (5C7), smooth to minutely roughened with distinct appendages measuring 5.1–10.1 (7.6, n = 10) × 1.92 – 3.24 (2.5, n = 10) µm. Asci globose to ovoid, 8-spored, 5.4 – 8 (6.7, n = 84) × 3 – 6.1 (4.7, n = 84) µm in size. Ascospores aseptate, fusoid, smooth, greyish orange (5B6); 2.6 – 4 (3.2, n = 216) × 1.6 – 3 (2.1, n = 216) µm in size. Culture characteristics — (12 h white fluorescent light / 12 h dark at 25 °C): Colonies at first yellow-orange to dark orange (4A7 /8 – 5A8), in age changing to brown-orange to brown (6C8 – 6E8) after 10 d. and colony colouration. Samson (1972) described P. bhattii as being characterised by yellow ascomata and the absence of distinct peridial appendages. However, P. lindneri can be distinguished from P. bhattii based on conidiogenesis (P. bhattii does not produce conidia) and the presence of distinct peridial appendages. Minnis & Lindner (2013), were the first to study many Pseudogymnoascus taxa using modern phylogenetic methods using a multigene approach. In their work, they identified multiple clades of Pseudogymnoascus. The new species described here is identical in the three genes studied to the same three genes from Minnis & Lindner’s 02NH05 isolate deposited in GenBank. Isolate 02NH05 up until this point has remained an undescribed homothallic species since the publication of their work. This work is the first to unite morphological characters used by Samson (1972) with molecular data.

Phylogenetic placement of Pseudogymnoascus lindneri on a maximum parsimony tree with maximum likelihood/maximum parsimony bootstrap support values, generated from the concatenated dataset of three loci (rDNA, TEF and RPB2) using PAUP v. 4.0a build 166 (Swofford 2003). The parsimony analysis generated a single most parsimonious tree via strict consensus. A maximum likelihood analysis was completed using GARLI v. 2.01 (Zwickl 2006) on the CiPRES Science Gateway (Miller et al. 2010). We generated a consensus tree from a single replicate ML analysis with 1 000 bootstrap pseudo-replications. The General Time Reversible (GTR) evolutionary model was used with estimate selected for the proportion of invariant sites, and gamma distribution as the model of rate heterogeneity.

Culture characteristics — (12 h white fluorescent light / 12 h dark at 25 °C): Colonies at first pastel yellow to light yellow (3A3 – 5), in age changing to reddish golden to brown-orange (6C7– 8) after 10 d. Notes — Morphological analyses suggest that P. turneri, P. lindneri and P. bhattii could be sister taxa. They are similar in the morphological characteristics of gymnothecial ascomata production and colony colouration. Samson (1972) described P. bhattii as being characterised by yellow ascomata and the absence of distinct peridial appendages. However, P. turneri can be distinguished from P. bhattii based on conidiogenesis (P. bhattii does not produce conidia) and the presence of distinct peridial appendages. Pseudogymnoascus turneri can be distinguished from P. lindneri based on ascospore dimensions (P. lindneri ascospores are smaller in size: 2.6 – 4 × 1.6 – 3 (3.2 × 2.1 µm, n = 216) and gymnothecial dimensions (P. lindneri gymnothecia are larger, 181–311 µm diam (220, n = 20). Minnis & Lindner (2013) were the first to analyse many Pseudogymnoascus taxa using modern phylogenetic methods using a multigene approach. In their work, they identified multiple clades of Pseudogymnoascus. The new species described here is identical in the three genes analysed to the same three genes from Minnis & Lindner’s 23342-1-I1 isolate. Isolate 23342-1-I1 has remained an undescribed homothallic species since the publication of their work. In addition to the morphological differences elucidated between P. turneri and P. lindneri, there is strong bootstrap support separating these species based on a three-gene-phylogeny.

Hortiboletus rubellus has reddish orange context in the lower stipe, tubes that split lengthwise when torn, and smaller spores, 10 –13 × 4 – 5 µm. Pulchroboletus rubricitrinus has a similarly coloured pileus that lacks a bright yellow margin, has a more yellow, longitudinally striate stipe streaked with red, and has different macrochemical reactions. Aureoboletus mirabilis is found in the Western USA with conifers, has a dark purplish red to reddish brown pileus, a yellow pore surface and context that does not stain blue. Xerocomus morrisii has a brown pileus, yellow context that does not stain blue, a yellow pore surface that becomes brownish orange to brick-red in age, and a punctate stipe. Hemileccinum subglabripes has an ochre to reddish brown pileus, a yellow pore surface that does not stain blue, and red to reddish brown punctae on its stipe. Pulchroboletus sclerotiorum is also distinct based on molecular characters. BLAST searches based on ITS rDNA did not match closely with any known boletes. The most closely related named taxa in GenBank are P. roseoalbidus, P. rubricitrinus, Boletus smithii and Gasteroboletus vividus. However, sequences of these taxa were < 91 % similar across the ITS. ITS sequences provide important insight into the ecology of this new species because they match a sequence from orange sclerotia collected beneath oaks in Massachusetts (Smith & Pfister 2009). Sclerotia of ectomycorrhizal fungi are rarely reported in the literature (Smith et al. 2015) but several other species of ectomycorrhizal Boletales have been shown to form sclerotia, including B. rubropunctus (Smith & Pfister 2009) and Leccinum holopus (Müller & Agerer 1990).

Ullah BS80 (LAH 36220, ITS, LSU, mtSSU and rpb2 sequences GenBank MN053391, MN513043, MN053396 and MN053390). Notes — The type ITS sequence has the closest GenBank BLAST match (98.7 %) with an unidentified Russula from China (GenBank JQ991794) and the most similar sequences identified to species are those of R. tengii (95.6 %) and R. dryadicola (95.6 %). Our multi-locus phylogenetic analysis based on nrITS, rpb2 and mtSSU clearly places R. quercus-floribundae in the R. globispora lineage as sister of two sequences of unidentified Russula from China (for the phylogenetic tree, see Supplementary Fig. FP1030). They form a well-supported clade with R. abbottabadensis from Pakistan and R. heilongjiangensis from China. All Asian species share features typical for the R. globispora lineage: brownish yellow spots on basidiomata, red and soon discolouring pilei and large spores with prominent spines. Russula dryadicola, R. globispora and R. tengii differ in isolated spines of spore ornamentation that do not form chains (Caboň et al. 2019). Russula heilongjiangensis has similar spore ornamentation but has narrower hymenial cystidia on lamellae sides (Li et al. 2018). Russula quercus-floribundae has, together with sequestrate species R. mediterraneensis and R. mattiroloana, the largest spores within the lineage, often exceeding 11 μm (Vidal et al. 2019).

Liu & L. Cai, sp. nov. Etymology. Named after the habitat of this fungus, occurring in a cave. Classification — Phaeosphaeriaceae, Pleosporales, Dothideomycetes. Ascomata brown to dark brown, solitary or gregarious, globose to subglobose, semi-immersed, usually covered by aerial mycelia, erumpent. Peridium hyaline to pale brown, 12 – 20 μm wide, with 3 – 5 layers, walls of textura angularis. Asci cylindrical to cylindrical-clavate, 8-spored, wall easy to dissolve and invisible. Ascospores hyaline, fusoid-ellipsoidal with rounded ends, 3-septate and constricted at the first and second septa, the second cell from apex wider than other cells, 17– 28.5 × 3.5–6 μm (av. = 22.4 ± 2.8 × 4.6 ± 0.5 μm). Asexual morph: Conidiophores hyaline, branched, often reduced to conidiogenous cells lining in the inner cavity. Conidiogenous cells hyaline, smooth, ovoid, ampulliform or subcylindrical, aseptate, 5–7.5 × 2–6 μm (av. = 6.3 ± 0.7 × 3.8 ± 1 μm). Conidia aseptate, hyaline, granular to guttulate, surface smooth or roughened, variable in shape and size, globose, ellipsoid or irregularly, 3 –16.5 × 2.5 –10.5 μm (av. = 7.4 ± 3.8 × 5.4 ± 2.1 μm). Culture characteristics — On potato dextrose agar, flat with lobate edge, buff, sometimes olivaceous at the edge, reverse buff, reaching 27– 30 mm diam after 10 d at 25 °C. On malt extract agar, flat with undulate edge, front and reverse buff, reaching 17–18 mm diam after 10 d at 25 °C. Notes — The oligotrophic fungus S. caverna was isolated from carbonatite using 1/2 000 PDA and silica agar (Jiang et al. 2017), and this is the first report of a Setophoma species from a Karst cave. It differs from other Setophoma species, in that the peridium of S. caverna is hyaline, and its ascus wall was difficult to observe, which is probably due to its adaptation to the cave habitat. It is closely related with the tea plant associated species S. longinqua (Liu et al. 2019b), but with low sequence similarity (95 % on ITS, 92 % on tef-1α and 90 % on tub2). Morphologically, they could be easily distinguished from each other by the conidial shape and dimensions (globose or ellipsoid, 3 –16.5 × 2.5 –10.5 μm in S. caverna vs cylindrical or subcylindrical, 4 – 5.5 × 1.5– 2 μm in S. longinqua).

Etymology. Refers to the oblong conidia that distinguish this species from the related S. resinae. Classification — Herpotrichiellaceae, Chaetothyriales, Eurotiomycetes. Ascomata not observed. Conidiomata mononematous or synnematous and arising from dark brown, well-developed subiculum. Synnemata scattered or gregarious, up to about 2 mm tall, dark brown to black, often splayed at the base but with a compact cylindrical stipe c. 60 – 80 µm wide, and a compact, dry, ellipsoidal conidial head c. 300 × 150 µm. Hyphae of stipe brown to dark brown, strictly parallel in the main part of the stipe, infrequently branched, with some anastomoses between adjacent hyphae, frequently septate, cells about 10 – 22 µm long, somewhat interwoven and rough-walled towards the base and (2.5 –)3.5 – 5 µm wide, walls 0.5 –1 µm thick, uneven in outline, smooth-walled and 2 – 3 µm wide in the main body of the stipe. Conidiogenous cells terminal or in pairs at the ends of the stipe hyphae, cylindrical and very similar in size to the conidia, but with a truncate base the same width as the stipe hyphae, 10–13 × 3.5– 4.5 µm, or intercalary and arising as a lateral extension about 7–10.5 × 3.5 µm from a shorter stipe hyphal cell, lacking a basal septum. Conidia in sparingly branched acropetal chains, oblong-ellipsoidal to almost fusiform, (8.5 –)11.5 –15(–18.5) × (2.5 –)3 – 4(– 4.5) µm (length: n = 126, av. = 13.2 μm, SD = 1.9 μm, SE = 0.17 μm, 95 % CI = 0.33; width: n = 126, av. = 3.5 μm, SD = 0.4 μm, SE = 0.04 μm, 95 % CI = 0.07), brown, mostly aseptate, fewer than 5 % of the conidia with a ± central septum, with lateral walls 0.5–1 µm thick, with no visible secession scars, connection almost a point to a flat area about 1.5 µm wide, smooth-walled, sometimes adjacent conidia anastomosing; ramoconidia infrequent, 11–15.5 × 3.5 – 4 µm, usually with just two emerging chains, conidial chains appressed and more or less parallel. Culture characteristics — Colonies after 4 wk at 20 °C on malt extract agar restricted, coal-black, brittle and wrinkled. Synnemata not produced. Typus. canada, New Brunswick, Charlotte County, Campobello Island, Roosevelt Campobello International Park, Fox Farm Trail, 44.849288, -66.966173, on resin on self-pruned branch stub of Picea rubens (Pinaceae), 26 Sept. 2016, J.B. Tanney (holotype DAOM 867433, culture ex-type DAOMC 251618, culture ex-paratype DAOMC 241619; ITS and LSU sequences GenBank MN114116 and MN114118, MycoBank MB831660). Notes — Sorocybe oblongispora differs from the type species, S. resinae, by its longer, narrower conidia (mostly 11.5 –15 × 3 – 4 µm vs 5.5 ‒11 × 2.5‒ 3.5 μm in S. resinae) and ramoconidia (11–15.5 × 3.5 – 4 µm vs 7‒12 × 4 ‒7 um). Both appear to be restricted to conifer resin, where they produce conspicuous synnemata and a less conspicuous mononematous morph. In North America, S. oblongispora occurs on the east coast of Canada on Picea rubens, and S. resinae in the Pacific Northwest of Canada and the USA on Abies, Picea, and Pseudotsuga spp. Sorocybe resinae was described from resin Colour illustrations.

The other two species, S. indica with slimy conidia (Pratibha et al. 2005) and the poorly-known S. tenella (Hughes 1958), seem unlikely to belong in Sorocybe as now circumscribed. Phylogenetic analyses of ITS and LSU sequences confirm that S. oblongispora DAOMC 251618 and S. resinae DAOM 239134 are congeneric (ITS: GenBank EU030275; Identities = 479/499 (96 %), 3 gaps (0 %); LSU: GenBank EU030277; Identities = 867/874 (99 %), 1 gap (0 %)). Our LSU phylogeny places S. oblongispora and S. resinae in a strongly-supported clade sister to Ceratosporella novae-zelandiae (incertae sedis), potentially a long-branch attraction artefact, a sequence misidentified as Lasallia pustulata (Umbilicariaceae, Umbilicariales), and Endococcus fusigera (incertae sedis). This well-supported (PP = 0.97) clade is in turn sister to Verrucaria (Verrucariaceae, Verrucariales). Based on an NCBI GenBank BLASTn query of the S. oblongispora DAOMC 251618 ITS sequence, the closest related taxon after S. resinae is Endococcus fusigera (GenBank FJ645262; Identities = 652/748 (87 %), 22 gaps (2 %)). Seifert et al. (2007) placed S. resinae sister to Capronia villosa (Herpotrichiellaceae, Chaetothyriales) from an ITS phylogeny (GenBank EU030275; Identities = 418/492 (85 %), 3 gaps (3 %)). We cannot confidently place Sorocybe in a family using the available reference sequences and Vu et al.’s (2019) rDNA taxonomic threshold values as a guide, but tentatively maintain this classification of Sorocybe within Herpotrichiellaceae pending further investigation. Sorocybe oblongispora was commonly found in New Brunswick, Canada on Picea rubens resin flows associated with self-pruned branch stubs or wounds. The resin was older and blackish in colour from the proliferation of mycelia from S. oblongispora and an unidentified sooty mould (Capnodiales). Sorocybe oblongispora co-occurred with other resinicolous fungi including Eustilbum aureum, Claussenomyces olivaceus, Lachnellula resinaria, Sarea difformis, S. resinae, and hysteriaceous species. Resinicolous fungi have been little studied in recent years and the known species are poorly represented by public DNA sequences. This recent discovery of Chaenothecopsis claydenii and now S. oblongispora highlights the undiscovered resinicolous fungal diversity of the Acadian forests of eastern Canada.

Inoculated seeds of BMX Bônus 8579 IPRO and M6210 IPRO cultivars had the germination reduced by 50 % and 70 %, respectively, and gave rise to plantlets with damping-off symptoms. Based on the similarity of symptoms, it is very likely that the disease caused by S. vannaccii in soybean is being confused with damping-off caused by Colletotrichum spp. in the field. Further studies should show the real importance of this disease to the soybean crop. Stagonosporopsis spp. has been reported causing diseases in other cultures in Brazil, such as S. caricae in Carica papaya (Aveskamp et al. 2010, Vivas et al. 2014) and S. cucurbitacearum in Luffa cylindrica (Silva et al. 2013b), and also in other countries, such as S. tanaceti, S. chrysanthemi and S. inoxydabilis in Asteraceae in Australia (Vaghefi et al. 2012), S. cucurbitacearum in Cucumis melo in Thailand (Nuangmek et al. 2018) and S. cucurbitacearum, S. citrulli and S. caricae in Cucurbita species (Stewart et al. 2015). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hit using the LSU sequence is Allophoma minor strain CBS 315.83 (GenBank GU238106.1; Identities = 1 326/1 327 (99.9 %), no gaps). Closest hits using the ITS sequence are Stagonosporopsis trachelii isolate NJ1-2 and strain CBS 384.68 (GenBank MH062183.2 and GU237856.1, respectively; Identities = 471/475 (99.2 %), no gaps). The closest hits using the tub2 sequence are S. ligulicola strain SWJ-6 and strain NB-5 (GenBank KJ868169.1 and KJ868168.1, respectively; Identities = 321/333 (96.44 %), 2 gaps (0.3 %)) and S. inoxydabilis strain CBS 425.90 (GenBank GU237693.1; Identities = 321/333 (96.44 %), 2 gaps (0.3 %)). The closest hit using the tef-1α sequence is Neodidymella thailandicum strain MFLUCC 11-0140 (GenBank MG520938.1; Identities = 884/ 902 (98.0 %), no gaps).

Notes — A BLAST search against an ex-type reference sequence dataset placed the new species in Talaromyces sect. Trachyspermi (Yilmaz et al. 2014). A multigene phylogeny based on ITS, BenA, CaM and RPB2 resolves T. clemensii as sister to T. diversus. All four genes distinguish between these species. Morphologically, both species are distinguished by poor growth on CYA. Talaromyces clemensii is distinguished from T. diversus by its inability of growth on CYA at 37 °C, and more restricted growth on OA (10 –11 vs 25 – 40 mm).

Notes — Tuber lucentum is distinguished from T. gennadii and T. lacunosum based on its very small ascomata, its gleba lacking isolated locules or continuous labyrinthine locules, and ITS sequence identity. The evolutionary history of 22 taxa was inferred using the Maximum Parsimony and the Neighbour-Joining methods. The bootstrap consensus tree inferred from 500 replicates is taken to represent the evolutionary history of the taxa analysed. Branches corresponding to partitions reproduced in less than 50 % bootstrap replicates are collapsed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) are shown next to the branches. The MP tree was obtained using the Close-Neighbour-Interchange algorithm with search level 3. The evolutionary distances were computed using the Maximum Composite Likelihood method. All positions containing gaps and missing data were eliminated from the dataset (Complete Deletion option). There were a total of 487 positions in the final dataset, out of which 114 were parsimony informative. Maximum Parsimony and the Neighbour-Joining were similar in bootstrap support. Phylogenetic analyses were conducted in MEGA 4.

Notes — The genus Veloporphyrellus was originally described based on V. pantoleucus from Costa Rica (Gómez & Singer 1984). It is characterised by the whitish to pink tubular hymenophore, the pinkish to brownish pink spore print, the smooth, elongate to fusiform basidiospores, trichodermial pileipellis and the extending membranous veil remnants on the pileus margin which often embraces the apex of the stipe (Wu et al. 2016). Li et al. (2014) considered the genus as monophyletic. However, in the work of Wu et al. (2016) its monophyly was questioned because species of this genus nested into two clades. Considering the morphological similarities and following latest work (Wu et al. 2016) we treat our new species as Veloporphyrellus until further data are available. The closest species is V. gracilioides, from which the new species differs by the brighter reddish- or orange-brown colour of the basidiomata and less developed pileus margin. Due to macromorphology V. vulpinus resembles Austroboletus gracilis, with the exception of the non-reticulate stipe surface. But like other Austroboletus species A. gracilis possesses ornamented pitted spores, while the spores of Veloporphyrellus are smooth. Colour illustrations.

Etymology. Referring to the fungus growing on submerged plant debris. Classification — Venturiaceae, Venturiales, Dothideomycetes. Mycelium consisting of branched, septate, subhyaline to pale olivaceous, smooth-walled 2–5 µm diam hyphae. Conidiophores mononematous, growing laterally on hyphae, micronematous, reduced to a conidiogenous cell, or macronematous, erect, unbranched, more rarely branched, subcylindrical, pale olivaceous, smooth-walled, up to 30 µm long. Conidiogenous cells terminal, polyblastic, with up to three denticle-like conidiogenous loci, smooth-walled, pale olivaceous, 11–24 × 2–4 µm, forming conidia in simple or branched acropetal chains. Ramoconidia 0(–1)-septate, cylindrical, with truncate base, up to three terminal or subterminal conidiogenous loci, smooth-walled, pale olivaceous, 13 – 24 × 2 – 4 µm. Conidia fusiform, ellipsoidal or cylindrical, 0(– 2)-septate, pale olivaceous, smooth-walled, 7–15 × 3– 4(– 5) µm. Sexual morph not observed.

On potato carrot agar (PCA) reaching 8 –10 mm, brownish grey (4F2), velvety, flat, aerial mycelium scarce, regular margin; reverse black. On oatmeal agar (OA) reaching 8–10 mm diam, grey (4F1), velvety, flat, aerial mycelium scarce, regular margin; reverse dark brown (6F8). Cardinal temperature for growth — Minimum 5 °C, optimum 20 °C, maximum 25 °C. Typus. Spain, Segovia, Riaza, on submerged plant debris, May 2018, I. Iturrieta-González, V. Magaña-Dueñas & D. García (holotype CBS H-24081, cultures ex-type FMR 17405; ITS and LSU sequences GenBank LR536046 and LR536048, MycoBank MB831789). Notes — Based on a megablast search of NCBIs GenBank nucleotide database, the LSU sequence of Venturia submersa showed a similarity of 99.77 % (857/859) with the sequence of V. barriae (CBS 621.84, GenBank EU035431) and of 99.42 % (854/859) with that of V. hystrioides (CBS 117727, GenBank 0.02 Colour illustrations. Riaza, Segovia, Spain. Colony sporulating on PCA after 2 wk at 25 °C; conidiophores and conidia after 10 d. Scale bars 10 mm (colony), 10 µm (microscopic structures). EU035459); while the ITS sequence was 96.44 % (488/506) similar with that of the latter species (CBS 117727, GenBank EU035459) and 95.46 % (484/ 507) with V. barriae (CBS 621.84, GenBank EU035431). The phylogenetic reconstruction using ITS barcodes of different accepted Venturia species, including the type V. inaequalis, showed that the new species was located in an unsupported clade together with V. barriae, V. hystrioides, V. inopina, V. populina, V. tremulae and V. saliciperda, being closely related with the former two species. Venturia barriae, formerly Fusicladium fagi, and V. hystrioides, formerly Capronia hystrioides, were described from decaying leaves of Fagus sylvatica and from scar of cherry fruit, respectively (Dugan et al. 1995, Crous et al. 2007c, Rossman et al. 2015). Morphologically, our new species differs from V. barriae in having longer conidiophores (up to 30 µm long vs up to 15 µm long in V. barriae), commonly aseptate and shorter conidia (7–15 µm vs up to 40 µm in V. barriae), and slower growth on PDA after 4 wk in darkness (23 mm in V. submersa vs 50 mm at 25 °C in V. barriae). Venturia hystrioides differs from V. submersa in the absence of macronematous conidiophores, larger ramoconidia (up to 30 µm long) with more septa (0 – 3), and by its more rapid growth on PDA and OA (reaching 40 mm after 2 wk at 25 °C in dark) (Crous et al. 2007c).
