TL;DR: Both asexual and sexual genera are merged into one outline for the phylum Ascomycota, which comprises of three subphyla viz.
Abstract: Taxonomic placement of genera have been changing rapidly as taxonomists widely use DNA sequence data in phylogenetic and evolutionary studies It is essential to update existing databases/outlines based on recent studies, since these sources are widely used as a foundation for other research In this outline, we merge both asexual and sexual genera into one outline The phylum Ascomycota comprises of three subphyla viz Pezizomycotina (including 13 classes, 124 orders and 507 families), Saccharomycotina (including one class, one order and 13 families) and Taphrinomycotina (five classes, five orders and six families) Approximately, 6600 genera have been listed under different taxonomic ranks including auxiliary (intermediate) taxonomic ranks

TL;DR: Both studies reveal that the micro-fungi on Pandanaceae is particularly rich in hyphomycetes.
Abstract: This paper provides illustrated descriptions of micro-fungi newly found on Pandanaceae in China and Thailand. The fungi are accommodated in 31 families. New taxa described include a new family, seven new genera, 65 new species, 16 previously known species. A new family: Malaysiascaceae (Glomerellales). New genera are Acremoniisimulans (Plectosphaerellaceae), Pandanaceomyces, Pseudoachroiostachy (Nectriaceae), Pseudohyaloseta (Niessliaceae), Pseudoornatispora (Stachybotriaceae) and Yunnanomyces (Sympoventuriaceae). New species are Acremoniisimulans thailandensis, Beltrania krabiensis, Beltraniella pandanicola, B. thailandicus, Canalisporium krabiense, C. thailandensis, Clonostachys krabiensis, Curvularia chonburiensis, C. pandanicola, C. thailandicum, C. xishuangbannaensis, Cylindrocladiella xishuangbannaensis, Dictyochaeta pandanicola, Dictyocheirospora nabanheensis, D. pandanicola, D. xishuangbannaensis, Dictyosporium appendiculatum, Di. guttulatum, Di. hongkongensis, Di. krabiense, Di. pandanicola, Distoseptispora thailandica, D. xishuangbannaensis, Helicoma freycinetiae, Hermatomyces biconisporus, Lasiodiplodia chonburiensis, L. pandanicola, Lasionectria krabiense, Menisporopsis pandanicola, Montagnula krabiensis, Musicillium pandanicola, Neofusicoccum pandanicola, Neohelicomyces pandanicola, Neooccultibambusa thailandensis, Neopestalotiopsis chiangmaiensis, N. pandanicola, N. phangngaensis, Pandanaceomyces krabiensis, Paracylindrocarpon nabanheensis, P. pandanicola, P. xishuangbannaensis, Parasarcopodium hongkongensis, Pestalotiopsis krabiensis, P. pandanicola, Polyplosphaeria nabanheensis, P. pandanicola, P. xishuangbannaensis, Pseudoachroiostachys krabiense, Pseudoberkleasmium pandanicola, Pseudochaetosphaeronema pandanicola, Pseudohyaloseta pandanicola, Pseudoornatispora krabiense, Pseudopithomyces pandanicola, Rostriconidium pandanicola, Sirastachys phangngaensis, Stictis pandanicola, Terriera pandanicola, Thozetella pandanicola, Tubeufia freycinetiae, T. parvispora, T. pandanicola, Vermiculariopsiella hongkongensis, Volutella krabiense, V. thailandensis and Yunnanomyces pandanicola. Previous studies of micro-fungi on Pandanaceae have not included phylogenetic support. Inspiration for this study came from the book Fungi Associated with Pandanaceae by Whitton, McKenzie and Hyde in 2012. Both studies reveal that the micro-fungi on Pandanaceae is particularly rich in hyphomycetes. All data presented herein are based on morphological examination of specimens, coupled with phylogenetic sequence data to better integrate taxa into appropriate taxonomic ranks and infer their evolutionary relationships.

TL;DR: Phylogenetic analyses of combined LSU, ITS and TEF1-α sequence data support these two species as distinct and confirm their phylogenetic affinities within the Tubeufiaceae, in particular, Kamalomyces shares a close phylogenetic relationship to Helicoma.
Abstract: Two novel species of bambusicolous fungi in the genus Kamalomyces, collected from northern Thailand, are described and illustrated herein. Kamalomyces bambusicola and K. thailandicus spp. nov. are typical of the genus Kamalomyces (Tubeufiaceae, Tubeufiales) and are morphologically distinct from known species with respect to their size of ascomata, asci and ascospores, ascospore septation and peridium structure, including the subiculum comprising hyphae on the host surface. Morphological examination reveals that the asexual morph of K. bambusicola is associated with its sexual morph in a subiculum forming dictyochlamydosporous conidia, which are similar to the asexual morph of Chlamydotubeufia. Phylogenetic analyses of combined LSU, ITS and TEF1-α sequence data also support these two species as distinct and confirm their phylogenetic affinities within the Tubeufiaceae. In particular, Kamalomyces shares a close phylogenetic relationship to Helicoma.

TL;DR: Maximum likelihood and Bayesian inference analyses of a combined ITS, LSU and RPB2 DNA sequence dataset show that V. yunnana is a new species, belonging to the genus Vamsapriya in Xylariaceae.
Abstract: Vamsapriya yunnana sp. nov., collected from dead bamboo in Yunnan Province of China, is described and illustrated in this paper. The new taxon is characterized by synnematous conidiophores, with enteroblastic, monotretic conidiogenous cells and brown to dark brown, 4–9-septate, fusiform conidia with a long, apical, appendage-like region. The species differs from the type and other species in the genus in having a wider fertile region and rostrate apex of the conidia. Maximum likelihood and Bayesian inference analyses of a combined ITS, LSU and RPB2 DNA sequence dataset show that V. yunnana is a new species, belonging to the genus Vamsapriya in Xylariaceae.

TL;DR: The species is markedly different from extant species of Fissuroma in having broad cylindric-clavate asci with long, club-shaped apical and basal appendages and distinct thick mucilaginous sheath in ascospores.
Abstract: Fissuroma taiwanense sp. nov. was collected from Shihnong Forest Area in Chiayi, Taiwan (Elevation 350m) and is the first report of a Fissuroma species from Hedychium (Zingiberaceae). The species is markedly different from extant species of Fissuroma in having broad cylindric-clavate asci with long, club-shaped apical and basal appendages and distinct thick mucilaginous sheath in ascospores. Combined analyses of LSU, SSU and tef1-α sequence data indicate a close relationship with F. maculans , the type species, but isolates of the new taxon are phylogenetically distinct. The new species is compared with other Fissuroma species and a comprehensive description and micrographs are provided.

TL;DR: A new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China, is reported.
Abstract: In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

TL;DR: Phylogenetic analyses of a combined ITS, LSU and SSU sequence data show that Marinophialophora garethjonesii constitutes an independent lineage with high statistical support basal to the genus Exophiala within the family Herpotrichiellaceae (Chaetothyriales).
Abstract: Marinophialophora garethjonesii sp. nov., representing a novel genus Marinophialophora gen. nov., associated with the basidiomycete fungus, Halocyphina on mangrove wood from Phetchaburi, Thailand, is described and illustrated. Marinophialophora morphologically resembles Phialophora and Junctospora (Herpotrichiellaceae, Chaetothyriales) in having macronematous, unbranched or branched conidiophores, globose to subglobose, solitary, acrogenous, pale to subhyaline, aseptate, conidia in chains and phialidic conidiogenous cells. Marinophialophora mainly differs from other related genera due to its conidia borne in basipetally developing branched chains and septate conidiophores. Phylogenetic analyses of a combined ITS, LSU and SSU sequence data show that Marinophialophora garethjonesii constitutes an independent lineage with high statistical support basal to the genus Exophiala within the family Herpotrichiellaceae (Chaetothyriales). The new marine taxon is described herein with illustrations and relationships inferred from DNA sequence data.

TL;DR: The new Monochaetia sinensis is introduced as a novel taxon with a comprehensive description and illustration and forms a sister clade to M .
Abstract: This study embodies description of a novel Monochaetia species, from dead leaf of a Quercus sp. collected from Lijiang in Yunnan Province, China. Morphologically, it conforms to the characters of Monochaetia by presence of single apical and basal appendage on the conidia. The new species forms a sister clade to M . ilexae in the combined LSU-ITS and TUB2 sequence data based phylogenetic analyses and remain distinct from the latter species in having larger conidia, long apical appendage, long basal appendage and long conidiogenous cells. Therefore, we introduce Monochaetia sinensis as a novel taxon with a comprehensive description and illustration.
