The Asexual Morph of Seriascoma acutisporum (Occultibambusaceae, Pleosporales)

An investigation of freshwater fungi in Thailand resulted in the collection and isolation of a coelomycetous Seriascoma from submerged wood. The combined ITS and LSU sequence data placed the taxon within the sexual morphic Seriascoma acutisporum strains, ZHKUCC 22-0273 and ZHKUCC 22-0274, with high bootstrap support and confirmed the asexual morphic stage of the taxon. Seriascoma acutisporum MFLUCC 24-0091 shares the generic characteristics of having an immersed, eustromatic conidiomata and phialidic, cylindrical to ampulliform, hyaline, aseptate conidiogenous cells bearing hyaline conidia, but with smaller conidiomata and locules compared to other coelomycetous Seriascoma species.
