ABSTRACT
During a mycological survey of freshwater hyphomycetes on submerged leaves in southwest China, a new species, Anacraspedodidymum submersum, was isolated. The new species A. submersum is characterized by having monophialidic conidiogenous cells with funnel shaped collarettes and globose or subglobose, aseptate and hyaline conidia. Morphologically, A. submersum is somewhat similar to A. aquaticum and A. hyalosporum in conidiophores and conidiogenous cells, but can be easily distinguished by its subglobose to globose and smaller conidia. Phylogenetic analysis of combined ITS and LSU sequences show that the new species of Anacraspedodidymum clustered together with the genus Thozetella in Chaetosphaeriaceae. A full description, illustrations and a phylogenetic tree showing the position of A. submersum are provided herein.
