New species of freshwater fungi are constantly being introduced following our studies in Asia. In the present paper, Minutisphaera aquaticum sp. nov., is introduced from submerged wood collected in the Mekong River in eastern Thailand, and increases the known diversity of Minutisphaeraceae. Minutisphaera aquaticum is characterized by superficial, small globose, dark brown to black ascomata, bitunicate, fissitunicate, obovoid to broadly cylindrical asci and fusiform, hyaline ascospores with a supra-median primary septum and upper cells that are wider than the lower cells. The multigene phylogenetic analysis places the new taxon in a well-supported clade with the species in Minutisphaeraceae (Minutisphaerales). The new species is compared with other Minutisphaera species, description and illustration are provided.
Congratulations DF Bao and co-authors!
