A new species of Trimorphomyces (Basidiomycota, Tremellales) from Taiwan
Kirschner, Roland; Chen, Chee-Jen
A fungus forming gelatinous sporulating structures on a dead branch in Taiwan is described as species of Trimorphomyces, because a hyphal anamorph producing zygoconidia is connected with a teleomorph with longitudinally septate basidia. The species differs from the single other known species in the genus, Trimorphomyces papilionaceus, by the production of the zygoconidium by two neighbouring conidiogenous cells, whereas the zygoconidium is produced by a single conidiogenous cell in T. papilionaceus. In analyses of nuclear large subunit ribosomal RNA gene sequences, a Cryptococcus-like anamorph isolated from the sporulating structure forms clusters with other Trimorphomyces strains. Because the species from Taiwan is morphologically and genetically distinct from T. papilionaceus, it is described as new species. Type studies of the hyphomycete Anastomyces microsporus revealed its identity with the hyphal anamorph of T. papilionaceus.
