Fungi 1 new species hyphomycetes phylogeny taxonomy

Abstract

During a survey of microfungi inhabiting freshwater habitats in Guangxi Province, China, a new hyphomycetous species was found. Kirschsteiniothelia guangxiensis is described and illustrated based on morphology and phylogenetic analyses of combined LSU and ITS sequences. It is characterized by macronematous, mononematous, brown to dark brown, occasionally branched conidiophores, monoblastic, percurrent conidiogenous cells, and obclavate, olivaceous brown to brown, multi-euseptate conidia. Furthermore, whether the morphological disparities of dendryphiopsis asexual morph and sporidesmium-like asexual morph are congruent with their phylogenetic clustering are discussed.
