Two new species in Fuscosporellaceae from freshwater habitats in Thailand

Abstract

A survey of freshwater fungi in Thailand resulted in the discovery of two new species in Fuscosporellaceae, herein described as Fuscosporella aquatica and Mucispora phangngaensis. Fuscosporella aquatica has sporodochial colonies, irregular ellipsoidal and dark brown conidia with vesicular conidiogenous cells. Mucispora phangngaensis has macronematous, solitary conidiophores with percurrent proliferations and dark brown obovoid conidia. Phylogenetic analysis based on combined LSU and ITS sequence data support their placement in Fuscosporella and Mucispora (Fuscosporellaceae, Fuscosporellales). Both species formed distinct clades from their type species and present as the second species in each genus. Descriptions and illustrations of the new taxa are provided. DNA sequence data of Parafuscosporella mucosa (from ex-type strain) are provided in this study, and confirmed its phylogenetic placement.

“…The most specious phylum is Ascomycota, with freshwater representatives in 33 orders from different classes (Jones et al 2009). During the last decade, studies on lignicolous freshwater fungi focused on Ascomycota (Shearer 1993, Hyde et al 1996, Tsui et al 2000, Cai et al 2002, Ho et al 2002, Luo et al 2004, Yang et al 2017, and they are highly diverse in the class Dothideomycetes and Sordariomycetes with a few members of Eurotiomycetes, Orbiliomycetes and seldom Basidiomycetes (Wijayawardene et al 2017(Wijayawardene et al , 2018. In the Dothideomycetes there are two orders: Pleosporales and Jahnulales that support common freshwater fungi (Suetrong et al 2011, Zhang et al 2012 and in Sordariomycetes 14 orders have freshwater members, with Microascales and Savoryellales comprising both marine and freshwater taxa (Jones et al 2009, Zhang et al 2017.…”
