Two New Species

Lignicolous freshwater fungi represent one of the largest groups of Ascomycota. This taxonomically highly diverse group plays an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning. The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient is currently being studied in Asia. In this paper, we introduce two novel freshwater taxa viz. Tingoldiago hydeisp. nov. and T. clavatasp. nov. which were collected from freshwater substrates in Eastern Thailand. Morphological comparison based on the size of ascomata, asci and ascospores, as well as multi-gene phylogenetic analyses based on LSU, SSU, ITS and TEF1-α DNA sequences, supports their placement in Tingoldiago (Lentitheciaceae). Descriptions and illustrations of these two new species are provided.

Pseudodactylaria fusiformis sp. nov. was collected during an investigation of freshwater fungi along a north-south latitudinal gradient in the Asian region. Evidence for the new species is provided by morphological comparison and sequence data analysis. Pseudodactylaria fusiformis differs from other species in having hyaline conidiophores and fusiform, 0–1-septate hyaline conidia without a sheath. Phylogenetic analysis based on combined ITS and LSU sequence data was carried out to determine the phylogenetic placement of the species. Six Pseudodactylaria taxa clustered together and formed a monotypic clade representing the genus, and five species are well recognized. Pseudodactylaria fusiformis and P. camporesiana share a sister relationship and they are phylogenetically distinct species. A detailed description and illustration are provided, as well as the comparisons with similar taxa.

A New Species

During an investigation of micro-fungi inhabiting mangrove forests, a new species of Rhytidhysteron was collected and isolated from dead twigs of a mangrove tree. Rhytidhysteron mangrovei sp. nov. is introduced, described, illustrated and compared with accepted species in the genus. Morphological comparison based on the size of exciple, the appearance of ascomata and ascospore septations and size as well as the multi-gene phylogenetic analyses based on LSU, ITS and TEF DNA sequences support its establishment in Rhytidhysteron. Placement of the genus in Hysteriaceae is also well-supported. In addition, phylogenetic analysis and DNA sequence data indicate that Rhytidhysteron mangrovei is closely related to Rhytidhysteron thailandicum. However, R. mangrovei is morphologically distinct from R. thailandicum, by having a relatively smaller size of exciple and perpendicularly rough-striate ascomata.

Abstract We present herein the first phylogenetic analysis of the genus Chelidura and the taxonomic revision of the genus Chelidurella, stat. restit., based on DNA sequences. The results confirm the generic status of Chelidurella Verhoeff, 1902 and Mesochelidura Verhoeff, 1902, and they are removed from the synonymy with Chelidura and reinstated as valid genera. Many individual Chelidurella species are defined based on the combination of a few variable characters on the pygidium and forceps, and the systematics and phylogeny of this genus are unclear. The validity of most of the species is revisited here by molecular phylogenetic analyses, and individual morphological characters are evaluated for their relevance in the identification of all described species. We describe two new species to science, Chelidurella galvagnii Kirstová & Kočárek, sp. nov. from Austria, and C. pseudovignai Kočárek & Kirstová, sp. nov. from Italy and Austria; two species, C. guentheri Galvagni, 1994 and C. tatrica Chládek, 2017 are newly synonymized. Critical diagnostic characters are illustrated, and an identification key for males of Chelidurella is provided.

Greater Mekong Subregion

A collection of lignicolous freshwater fungi in the Greater Mekong Subregion resulted in four interesting dematiaceous hyphomycetes with similar morphology. The taxa had sporodochial colonies, micronematous to semi-macronematous conidiophores and subglobose, ellipsoidal to broadly pyriform, 0–1-septate, dark brown to black conidia. Based on morphological characters and phylogenetic analyses of combined LSU, SSU, ITS and RPB2 sequence data, Parafuscosporella aquatica sp. nov., P. pyriformis sp. nov., Conioscypha tenebrosa and Vanakripa minutiellipsoidea are identified. Parafuscosporella aquatica and P. pyriformis cluster within Fuscosporellaceae (Fuscosporellales), while C. tenebrosa and V. minutiellipsoidea are placed within Conioscyphales. This is the first report on the phylogenetic placement of Vanakripa. Descriptions and illustrations of the new collections are provided.

Two new species, Xylodon bambusinus and X. xinpingensis, are proposed based on morphological and molecular evidences. Both species share the annual growth habit, resupinate basidiomata and monomitic hyphal system with clamped, colorless generative hyphae, smooth, thin-walled basidiospores, but X. bambusinus is characterized by the smooth to tuberculate hymenial surface, presence of capitate and fusiform cystidia, broad ellipsoid basidiospores, while X. xinpingensis by the reticulate hymenophore with cream hymenial surface, and subglobose basidiospores (4.5–6 × 3.5–5 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS+nLSU sequences showed that X. bambusinus was sister to X. subclavatus, while X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus. The nLSU dataset revealed that X. bambusinus grouped with X. asperus and X. brevisetus with lower supports, and that X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus and then with X. rimosissimus without supports. Both morphological and molecular evidences confirmed the placement of two new species in Xylodon. Description and figures from the new species and a key to the known species of Xylodon from China are presented.

A New Species

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.
