... However, recent studies have shown that Ceratolenta did not cluster with Xylochrysis (Hyde et al. 2021). Species of Xylochrysis morphologically resembles species of Lentomitella, but it differs from Lentomitella in having cylindrical, long-stipitate asci (Réblová 2006;Réblová et al. 2014). Ascomata with a pigmented layer is a unique character observed in the species in Sordariales, Chaetosphaeriales, Calosphaeriales, Xenospadicoidales and Pararamichloridiales, while it only occurs in some other species (Réblová et al. 2014). ...
During surveys of ascomycetous fungi in Sichuan province, China, a new aquicolous taxon, Xylochrysis aquatica, isolated from a decaying trunk of an undetermined wood is described. Xylochrysis aquatica differs from the type species X. lucida in having solitary, smaller ascomata with a short papillate ostiole, without a golden yellow layer of surrounded cells and larger asci with rounded ascospores. The phylogenetic analysis of the combined ITS-LSU-SSU-rpb2-tef1-α sequence data matrix showed that X. aquatica clustered together with X. lucida and formed as different lineages, it can be recognized as a distinct species. A detailed description and an illustration of the novel species are given while a nucleotide comparison of related species is provided.

Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi mainly characterized by perithecial ascomata and inoperculate unitunicate asci. Freshwater Sordariomycetes play an important role in ecosystems and some of them have the potential to produce bioactive compounds. This study documents and reviews the freshwater Sordariomycetes, which is one of the largest and important groups of fungi in aquatic habitats. Based on evidence from DNA sequence data and morphology, we introduce a new order Distoseptisporales, two new families, viz. Ceratosphaeriaceae and Triadelphiaceae, three new genera, viz. Aquafiliformis, Dematiosporium and Neospadicoides, 47 new species, viz. Acrodictys fluminicola, Aquafiliformis lignicola, Aquapteridospora fusiformis, Arthrinium aquaticum, Ascosacculus fusiformis, Atractospora aquatica, Barbatosphaeria lignicola, Ceratosphaeria aquatica, C. lignicola, Chaetosphaeria aquatica, Ch. catenulata, Ch. guttulata, Ch. submersa, Codinaea yunnanensis, Conioscypha aquatica, C. submersa, Cordana aquatica, C. lignicola, Cosmospora aquatica, Cylindrotrichum submersum, Dematiosporium aquaticum, Dictyochaeta cangshanensis, D. ellipsoidea, D. lignicola, D. submersa, Distoseptispora appendiculata, D. lignicola, D. neorostrata, D. obclavata, Hypoxylon lignicola, Lepteutypa aquatica, Myrmecridium aquaticum, Neospadicoides aquatica, N. lignicola, N. yunnanensis, Ophioceras submersum, Peroneutypa lignicola, Phaeoisaria filiformis, Pseudostanjehughesia lignicola, Rhodoveronaea aquatica, Seiridium aquaticum, Sporidesmiella aquatica, Sporidesmium lageniforme, S. lignicola, Tainosphaeria lunata, T. obclavata, Wongia aquatica, two new combinations, viz. Acrodictys aquatica, Cylindrotrichum aquaticum, and 9 new records, viz. Chaetomium globosum, Chaetosphaeria cubensis, Ch. myriocarpa, Cordana abramovii, Co. terrestris, Cuspidatispora xiphiago, Sporidesmiella hyalosperma, Stachybotrys chartarum,S. chlorohalonata. A comprehensive classification of the freshwater Sordariomycetes is presented based on updated literature. Phylogenetic inferences based on DNA sequence analyses of a combined LSU, SSU, RPB2 and TEF1α dataset comprising species of freshwater Sordariomycetes are provided. Detailed information including their habitats distribution, diversity, holotype, specimens collected and classification are provided.
... The "ophiostomataceous" lineage comprised Ceratostomella s. str. and also Barbatosphaeria, Lentomitella, Natantiella, and Xylomelasma ( Höhnel 1906a, R eblov a 2006, Marincowitz et al. 2008, R eblov a & St ep anek 2009). The asexual morphs linked with genera of this lineage are dematiaceous hyphomycetes with holoblastic conidia produced on a sympodially extending rachis or on a terminal cluster of denticles. ...
The genus Ceratostomella has a long history of taxonomic confusion. While species with evanescent asci have been transferred to the Microascales and Ophiostomatales, the taxonomic status of species with persistent asci has not been completely resolved. In previous studies using DNA sequence data, cultures and morphology, several Ceratostomella spp. were allocated in 13 genera in the Eurotiomycetes and Sordariomycetes. In our study, the systematics of the remaining Ceratostomella spp. with persistent asci is revisited with new collection data, cultures and phylogeny based on novel DNA sequences from six nuclear loci. Bayesian inference and Maximum Likelihood analyses support the monophyly of several wood-inhabiting species formerly classified in Ceratostomella and other unknown morphologically similar taxa and their division into four genera, i.e. Lentomitella, Spadicoides, Torrentispora and the newly described Calyptosphaeria. This robust clade represents the order Xenospadicoidales in the Sordariomycetidae. Comparative analysis of the ITS2 secondary structure revealed a genetic variation among Lentomitella isolates; 11 species were recognised, of which five are newly introduced and two are new combinations. Other taxonomic novelties include four new species and eight new combinations in Calyptosphaeria, Spadicoides, and Torrentispora. Molecular data suggest that Spadicoides is polyphyletic. The core of the genus is positioned in the Xenospadicoidales; Spadicoides s. str. is experimentally linked with sexual morphs for the first time. Based on DNA sequence data, the monotypic genera Xenospadicoides and Pseudodiplococcium are reduced to synonymy under Spadicoides, while Fusoidispora and Pseudoannulatascus are synonymised with Torrentispora. Members of the Xenospadicoidales inhabit decaying wood in terrestrial and freshwater environments and share a few morphological characters such as the absence of stromatic tissue, ascomata with a cylindrical or rostrate neck, similar anatomies of the ascomatal walls, thin-walled unitunicate asci with a non-amyloid apical annulus, disintegrating paraphyses, usually ellipsoidal to fusiform ascospores and holoblastic-denticulate or tretic conidiogenesis. Revised Ceratostomella spp. with persistent asci are listed and the taxonomic status of each species is re-evaluated based on revision of the holotype and other representative material, published details and available phylogenetic data.

In order to contribute to the knowledge of the fungal diversity in the Parque Nacional de Ordesa y Monte Perdido, a taxonomic revision of the species collected throught 2014 has been made, classified in three levels: a) new or very special interest species, b) interesting or uncommon species, c) other species. Given the breadth of the territory that has been studied, prospecting areas have been limited to the bassins of the Ara, Arazas, Bellós, Yaga and Cinca rivers.
311 taxa were identified, corresponding 240 to Phyllum Basidiomycota, 61 to Ascomycota and 10 to Myxomycota; the most representative orders are Agaricales, Russulales, Pezizales, Polyporales, Boletales and Helotiales. Among the identified species, have been found 9 between the proposals for the catalog of protected species of the Iberian Peninsula and/ or Aragón.
In this paper a first contribution to the catalog is showed, first as a list of all identified taxa and then, a taxonomic description with its macro and microscopic iconography for 16 of them, corresponding with interesting or uncommon species.

Endophytes fungi have been extensively studied in conifer needles involving culture dependent methods, however little number have been conducted in Pinus radiata and no record have been reported from Tasmania. This study aimed to identify the major group of endophyte fungi isolated from P. radiata needles with varied conditions collected from Tasmania, Victoria and New South Wales plantation and confirmed by phylogenetic analysis of ITS gene. Sixteen endophyte fungi species as member of Sordariomycetes were isolated and Coniochaeta sp. 1 was the most frequently isolated species in this study.
... In ascospore and to some extent ascus morphology, Pisorisporium resembles members of Ceratosphaeria, Ceratosphaerella and Pseudohalonectria of the Magnaporthaceae. They are similar in overall morphol ogy of fusiform, cylindrical to cymbiform, multiseptate, hyaline ascospores , but the three latter genera differ from Pisorisporium in a non-amyloid reaction of the apical annulus, long, sometimes flexuous protruding necks of ascomata and asexual morphs, i.e. harpophora-like and phialophora-like asexual morphs experimentally linked to Ceratosphaeria and the presumed Didy mobotryum-like asexual morph of Ceratosphaerella (Shearer 1989, Réblová 2006, Huhndorf et al. 2008). Moreover, species of Pseudohalonectria and Ceratosphaeria phialidica differ from Pisorisporium by cylindrical to cymbiform asci with ascospores arranged in a fascicle or rarely 4-seriately, while in Pisorispo rium, Ceratosphaeria and Ceratosphaerella the ascospores are predominantly 2-seriate within the ascus. ...
Four morphologically similar specimens of an unidentified perithecial ascomycete were collected on decaying wood submerged in fresh water. Phylogenetic analysis of DNA sequences from protein-coding and ribosomal nuclear loci supports the placement of the unidentified fungus together
with Achroceratosphaeria in a strongly supported monophyletic clade. The four collections are described as two new species of the new genus Pisorisporium characterised by non-stromatic, black, immersed to superficial perithecial ascomata, persistent paraphyses, unitunicate, persistent
asci with an amyloid apical annulus and hyaline, fusiform, cymbiform to cylindrical, transversely multiseptate ascospores with conspicuous guttules. The asexual morph is unknown and no conidia were formed in vitro or on the natural substratum. The clade containing Achroceratosphaeria
and Pisorisporium is introduced as the new order Pisorisporiales, family Pisorisporiaceae in the class Sordariomycetes. It represents a new lineage of aquatic fungi. A sister relationship for Pisorisporiales with the Lulworthiales and Koralionastetales
is weakly supported by Bayesian inference and maximum likelihood analyses. The systematic position of Pisorisporium among morphologically similar perithecial ascomycetes is discussed.
... Harpophora originally was defined as a hyphomycetous genus in Magnaporthales with phialidic, curved conidia (Gams 2000). According to this broad concept, several genera, for example, Buergenerula, Ceratosphaeria Niessl, Gaeumannomyces, Magnaporthiopsis, Pseudophialophora and Slopeiomyceshave harpophora-like asexual states (Cannon 1994, Réblová 2006, Huhndorf et al. 2008, Zhang et al. 2011, Luo and Zhang 2013, Luo et al. 2014. In this study we demonstrated that Harpophora is a synonym of Gaeumannomyces because the type species of Harpophora is congeneric to Gaeumannomyces. ...
We investigated the phylogenetic relationships among Magnaporthales fungi with harpophora-like asexual states based on DNA sequences of ITS, MCM7, RPB1 and TEF1 genes. The results indicated that these species are polyphyletic. Based on the four-gene phylogeny, the type species of Harpophora, H. radicicola, belongs to Gaeumannomyces and thus Harpophora is treated as a synonym of Gaeumannomyces. In addition a monotypic new genus, Falciphora, is established based on F. oryzae, previous referred as Harpophora oryzae.

... Gams (2000) introduced a new asexual genus, Harpophora W. Gams, to accommodate four Phialophora-like species characterized by fast growing colonies, pigmented phialides with a typical collarette, and strongly curved conidia that were reluctant to germinate on standard media. In Magnaporthaceae, Harpophora-like state was con-nected to, Buergenerula Syd., Ceratosphaeria Niessl and Gaeumannomyces Arx & D.L. Olivier, while Phialophora-like state was found in Magnaporthiopsis J. Luo & N. Zhang (Cannon 1994, Réblová 2006, Huhndorf et al. 2008, Zhang et al. 2011, Luo and Zhang 2013. ...
... The true Phialophora, including the type species P. verrucosa and its relatives, is linked to Capronia Sacc. in Herpotrichiellaceae of Chaetothyriales (Yan et al. 1995, Untereiner and Naveau 1999, de Hoog 1999. Based on phylogenetic studies (Gams 2000, Harrington and McNew 2003, Vijaykrishna et al. 2004, Thongkantha et al. 2009 In Magnaporthaceae, Buergenerula, Ceratosphaeria, Gaeumannomyces and Magnaporthiopsis were reported to have Phialophora-like or Harpophora-like asexual states (Cannon 1994, Réblová 2006, Huhndorf et al. 2008, Zhang et al. 2011, Luo and Zhang 2013. Our six-gene phylogenetic analysis indicates that Magnaporthiopsis (with Phialophora-like anamorphs) is a sister genus of Gaeumannomyces graminis (with Harpophora anamorphs). ...
... Gaeumannomyces cylindrosporus (with Harpophora anamorph) formed a distinct lineage. Ceratosphaeria lampadophora, the type species of the genus, and C. phialidica also produces Harpophora-like anamorphs (Réblová 2006, Huhndorf et al. 2008. Previous LSU and SSU rDNA sequence analyses suggested that it was close to Pseudohalonectria (Huhndorf et al. 2008, Thongkantha et al. 2009). ...
Based on morphology and DNA sequences of SSU, ITS, LSU, MCM7, RPB1 and TEF1 genes, we describe four new species in Magnaporthaceae that are associated with grass roots collected from New Jersey Pine Barrens. A new genus, Pseudophialophora, is erected to accommodate three species, which is characterized by slow growth on potato dextrose agar, curved conidiogenous cells without a conspicuous collarette at the apex and oblong ellipsoidal conidia. Pseudophialophora eragrostis, P. panicorum and P. schizachyrii are assigned to this genus. A new species of Magnaporthiopsis also is reported and named as M. panicorum. Distinctions between them and phylogenetic relationships with other Magnaporthaceae taxa are discussed.
... Material examined – USA, Virginia, Giles County, Salt Pond Mountain, on rotten wood, 5 Aug 2013, L. Vasilyeva, VLA P-2768 (holotype). Notes – The genus Xylomelasma was established recently (Réblová 2006) with two species, X. sordida Réblová and X. novaezelandiae Réblová, both of which have smaller ascospores in comparison with X. moderata. Rather similar is also Lentomitella tomentosa Réblová & J. Fournier, which has somewhat larger ascospores than X. moderata. ...
