<p><strong><em>Distoseptispora hydei</em> sp. nov. (Distoseptisporaceae), a novel lignicolous fungus on decaying bamboo in Thailand</strong></p>

Abstract

In this paper, we described and illustrated a new species of lignicolous fungi, Distoseptispora hydei, found on decaying bamboo in Phitsanulok Province, Thailand. According to the phylogenetic results from combined sequence data (LSU, ITS and RPB2), the new species is distinct from other Distoseptispora species. Distoseptispora hydei is characterized by obpyriform to fusiform conidia with 7–9 distosepta and a hyaline, gelatinous sheath around the tip. Phylogenetic analyses and morphological comparisons with other species of Distoseptispora are provided in this study.

Reappraisal of Immotthia in Dictyosporiaceae, Pleosporales: Introducing Immotthia bambusae sp. nov. and Pseudocyclothyriella clematidis comb. et gen. nov. Based on Morphology and Phylogeny

“…An updated taxonomic treatment of bambusicolous fungi has been conducted since the last decade by Japanese mycologists (Tanaka et al, 2009(Tanaka et al, , 2015 and followed by many Asian mycologists (Liu et al, 2011(Liu et al, , 2012(Liu et al, , 2014(Liu et al, , 2015Dai et al, 2012Dai et al, , 2014aDai et al, ,b,c, 2017Dai et al, , 2018Dai et al, , 2019Phookamsak et al, 2014Phookamsak et al, , 2015Phookamsak et al, , 2018Adamčík et al, 2015;Ariyawansa et al, 2015;Senanayake et al, 2015Senanayake et al, , 2020aJiang et al, 2018Jiang et al, , 2019aSommai et al, 2019;Yang et al, 2019a,b;Jiang H.

To date, more than 1,300 bambusicolous fungi have been reported consisting of 150 basidiomycetes and 1,150 ascomycetes.…”

Two novel species and two new records of Distoseptispora from freshwater habitats in China and Thailand

“…Preliminary identification of genes obtained from fresh strains by GenBank database. The LSU, ITS, SSU, TEF1-α, and RPB2 used for phylogenetic analysis are selected based on the preliminary identification results and the related publications (Yang et al 2018;Monkai et al 2020) Maximum likelihood (ML) analysis was carried out using the RAxML-HPC2 on XSEDE (8.2.12) (Stamatakis 2006;Stamatakis et al 2008) of CIPRES Science Gateway website (Miller et al 2010: http://www.phylo.org/portal2) and the estimated proportion of invariant sites is (GTRGAMMA+I) model.…”

“…This genus is not known for its sexual morph (Su et al 2016;Yang et al 2018;Hyde et al 2019Hyde et al , 2020Luo et al 2019;Sun et al 2020). Currently, 32 species are accepted in the genus of which 13 from terrestrial habitats and 19 were reported from freshwater environments (Su et al 2016;Hyde et al 2016aHyde et al , 2019Hyde et al , 2020Xia et al 2017;Yang et al 2018;Luo et al 2018Luo et al , 2019Monkai et al 2020;Song et al 2020;Sun et al 2020;Li et al 2021; Index Fungorum 2021 http://www.indexfungorum.org).…”

“…Two new species, Distoseptispora bangkokensis and D. lancangjiangensis, are introduced in this study, D. clematidis and D. thysanolaenae are newly recorded from freshwater habitats for the first time in China. Morphological descriptions and illustrations of the species and an updated multi-gene phylogenetic tree are provided to reveal their taxonomic position among the species in the Distoseptisporales, and also provided the comparison of morphological characteristics, habitats and hosts information of species newly added to Distoseptispora after Monkai et al (2020) (Table 2).…”

Novel saprobic Hermatomyces species (Hermatomycetaceae, Pleosporales) from China (Yunnan Province) and Thailand

“…Over the past few decades, the number of studies using a molecular-based approach to study microfungal diversity in the greater Mekong subregion (GMS) has increased rapidly, especially on freshwater and woody litter fungi from China (Yunnan Province) and Thailand (Hapuarachchi et al 2019;Dong et al 2020;Li et al 2020;Monkai et al 2020;Wanasinghe et al 2020Wanasinghe et al , 2021Mortimer et al 2021). Hyde et al (2018) reported that about 96% of fungi from Thailand are new to science.…”
