Abstract
BackgroundFreshwater fungi are highly diverse and ecologically important in freshwater systems. In China, more than 1000 species of freshwater fungi are known. Here, we present a brown-spored hyphomycetes that was collected on a submerged decaying bamboo culm in a forest stream in China.New informationPhylogenetic analyses of combined LSU, ITS and TUB2 sequences confirm the placement of our new strain in Veronaea (Herpotrichiellaceae), sister to V.japonica. Veronaeaaquatica sp. nov. differs from related taxa V.compacta and V.japonica in having longer conidiophores and cylindrical to pyriform or subclavate conidia with 0–2 septa. Veronaeaaquatica also has darker brown hyphae compared to V.japonica. A morphological description and detailed illustrations of V.aquatica are provided.
Highlights
Freshwater fungi are those taxa that grow in freshwater bodies for the entirety or only part of their life cycle (Goh and Hyde 1996, Dhanasekaran et al 2006)
Phylogenetic analyses of combined large subunit rDNA (LSU), internal transcribed spacer (ITS) and TUB2 sequences confirm the placement of our new strain in Veronaea (Herpotrichiellaceae), sister to V. japonica
We introduce Veronaea aquatica sp. nov., a freshwater species from submerged decaying bamboo culms collected in a stream in Jiangxi Province, China
