The present paper represents the fifth contribution in the Genera of Fungi series, linking type species of fungal genera to their morphology and DNA sequence data. This paper focuses on 11 genera of microfungi, for seven of which the type species are neo- or epitypified here: Arthrinium (Arthrinium caricicola; Apiosporaceae, Xylariales, Sordariomyc...

In the present work, an epitype for Sphaeria apiospora , the basionym of the type species of the genus Apiospora , Apiospora montagnei , is selected among collections growing in the host plant species reported in the original protologue, Arundo micrantha . Most samples obtained from localities near that of the lectotype (Perpignan, France) belong to the same species, which is not significantly different from the clade previously named Ap. phragmitis , suggesting that this name is a later synonym of Ap. montagnei . In addition, the name Ap. marianiae is here proposed to accommodate a newly discovered species found in the Balearic Islands (Spain), and the asexual state of Ap. sichuanensis is described for the first time from samples growing in the same islands.

Culture techniques are vital in both traditional and modern fungal taxonomy. Establishing sexual–asexual links and synanamorphs, extracting DNA and secondary metabolites are mainly based on cultures. However, it is widely accepted that a large number of species are not sporulating in nature while others cannot be cultured. Recent ecological studies based on culture-independent methods revealed these unculturable taxa, i.e., dark taxa. Recent fungal diversity estimation studies suggested that environmental sequencing plays a vital role in discovering missing species. However, Sanger sequencing is still the main approach in determining DNA sequences in culturable species. In this paper, we summarize culture-based and culture-independent methods in the study of ascomycetous taxa. High-throughput sequencing of leaf endophytes, leaf litter fungi and fungi in aquatic environments is important to determine dark taxa. Nevertheless, currently, naming dark taxa is not recognized by the ICN, thus provisional naming of them is essential as suggested by several studies.
During an investigation into lignicolous freshwater fungi from the plateau lakes in Yunnan Province, China, two fresh collections of Torula taxa were collected and examined morpholgically.
Torula luguhuensis is characterised by: conidiophores which are semi-macronematous mononematous, erect, septate, smooth, slightly flexuous and pale brown; conidiogenous cells which are holoblastic, mono- to polyblastic, integrated, terminal, terminal or intercalary in conidial chains, doliiform and pale brown; conidia which are branched chains, acrogenous, straight or slightly curved, dark brown to blackish, pale brown or subhyaline at apex, 1–3 septate, strongly constricted at the septa, verruculose or finely echinulate and rounded at both ends. A new species was introduced, based on morphological and phylogenetic analysis of combined ITS, LSU, RPB2 and TEF sequence data. Detailed descriptions and illustrations are provided, with an updated phylogenetic tree depicting intergeneric relationships within the Torulaceae.
While investigating the diversity of lignicolous fungi in Yunnan Province, China, six fresh collections of Torulaceae were collected and identified based on morphological examination and phylogenetic analyses of combined LSU, ITS, SSU, tef1-α , and rpb2 sequence data. Two new species, viz. Neopodoconis yunnanensis and Torula suae , and three new records, viz. T. canangae (new freshwater habitat record), T. masonii (new host record), and T. sundara (new freshwater habitat record) are reported. Detailed descriptions, illustrations, and a phylogenetic tree to show the placement of these species are provided.
Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz. Acrodictys chishuiensis, A. effusa, A. pyriformis, Actinocladium aquaticum, Annulatascus tratensis, Aquabispora setosa, Aqualignicola setosa, Aquimassariosphaeria vermiformis, Ceratosphaeria flava, Chaetosphaeria polygonalis, Conlarium muriforme, Digitodesmium chishuiense, Ellisembia aquirostrata, Fuscosporella atrobrunnea, Halobyssothecium aquifusiforme, H. caohaiense, Hongkongmyces aquisetosus, Kirschsteiniothelia dushanensis, Monilochaetes alsophilae, Mycoenterolobium macrosporum, Myrmecridium splendidum, Neohelicascus griseoflavus, Neohelicomyces denticulatus, Neohelicosporium fluviatile, Neokalmusia aquibrunnea, Neomassariosphaeria aquimucosa, Neomyrmecridium naviculare, Neospadicoides biseptata, Ocellisimilis clavata, Ophioceras thailandense, Paragaeumannomyces aquaticus, Phialoturbella aquilunata, Pleurohelicosporium hyalinum, Pseudodactylaria denticulata, P. longidenticulata, P. uniseptata, Pseudohalonectria aurantiaca, Rhamphoriopsis aquimicrospora, Setoseptoria bambusae, Shrungabeeja fluviatilis, Sporidesmium tratense, S. versicolor, Sporoschisma atroviride, Stanjehughesia aquatica, Thysanorea amniculi, Uvarisporella aquatica and Xylolentia aseptata, with an illustrated account, discussion of their taxonomic placement and comparison with morphological similar taxa. Seven new combinations are introduced, viz. Aquabispora grandispora (≡ Boerlagiomyces grandisporus), A. websteri (≡ Boerlagiomyces websteri), Ceratosphaeria suthepensis (≡ Pseudohalonectria suthepensis), Gamsomyces aquaticus (≡ Pseudobactrodesmium aquaticum), G. malabaricus (≡ Gangliostilbe malabarica), Neocirrenalia nigrospora (≡ Cirrenalia nigrospora), and Rhamphoriopsis glauca (≡ Chloridium glaucum). Ten new geographical records are reported in China and Thailand and nine species are first reported from freshwater habitats. Reference specimens are provided for Diplocladiella scalaroides and Neocirrenalia nigrospora (≡ Cirrenalia nigrospora). Systematic placement of the previously introduced genera Actinocladium, Aqualignicola, and Diplocladiella is first elucidated based on the reference specimens and new collections. Species recollected from China and Thailand are also described and illustrated. The overall trees of freshwater Dothideomycetes and Sordariomycetes collected in this study are provided respectively and genera or family/order trees are constructed for selected taxa.
Torula is an asexual and hyphomycetous genus in the family Torulaceae. Torula species are generally saprophytic. They have a worldwide distribution and abound in humid or freshwater habitats. In order to better understand this genus, we carried out several field collections from Sichuan, China. As a result, we obtained nine Torula isolates from dead woody substrates in terrestrial and freshwater habitats. Based on a biphasic approach of morphological examination and multi-locus phylogenetic analyses (ITS, SSU, LSU, TEF, RPB2), these collections were identified as belonging to seven Torula species. Four of them were new species (Torula chinensis, T. longiconidiophora, T. sichuanensis and T. submersa), and the other three belonged to existing species, though one was found for the first time in China (T. masonii). Morphological and updated phylogenetic delamination of the new discoveries is also discussed. This study provides further insights into our understanding of wood-based Torula species in China.

Stictidaceae comprises taxa with diverse lifestyles. Many species in this family are drought resistant and important for studying fungal adaptation and evolution. Stictidaceae comprises 32 genera, but many of them have been neglected for decades due to the lack of field collections and molecular data. In this study, we introduce a new species Fitzroyomyces hyaloseptisporus and a new combination Fitzroyomyces pandanicola. We also provide additional morphological and molecular data for Ostropomyces pruinosellus and O. thailandicus based on new collections isolated from an unidentified woody dicotyledonous host in Chiang Rai, Thailand. Taxonomic conclusions are made with the aid of morphological evidence and phylogenetic analysis of combined LSU, ITS and mtSSU sequence data. Characteristics such as the shape and septation of ascospores and conidia as well as lifestyles among genera of Stictidaceae are discussed.
