ABSTRACT: Henningsomyces leptus (Basidiomycota) is described as a new species. It is similar to H. candidus in hyphal structure and basidiospores dimensions. However, the new species differs from H. candidus by its longer and thinner tubes, its hyphae at tube-mouth (dissepimental edge) that are shortly branched, and the branches that taper sharply towards the end.
