Beta-tubulin and Actin gene phylogeny supports as a new species from freshwater habitats in China.

A new species of , (Togniniaceae), was isolated during a diversity study of freshwater fungi from Yunnan Province in China. Morphological and cultural studies of the fungus were carried out and its sexual and asexual morphs (holomorph) are introduced herein. This species is characterised by peculiar long-necked, semi-immersed ascomata with oval to ellipsoid ascospores and ellipsoid to ovoid conidia. Phylogenetic analyses of a combined TUB and ACT gene dataset revealed that strains of constitute a strongly supported independent lineage and are related to and . The number of nucleotide differences, across the genes analysed, also supports establishment of as a new species.
