Basidiospores of T. foliicola were irregularly ellipsoid, showing a cyanophilic reaction with or without tubercles. Phylogenetic analyses of the internal transcribed spacer (ITS) and large subunit 28S regions of the fungal nuclear ribosomal RNA gene demonstrated that T. foliicola is a species of Gerhardtia characterized by irregularly shaped basidiospores. Thus, we transferred this species to Gerhardtia foliicola comb. nov. Cultured mycelia of G. foliicola on malt extract agar medium produced cystidia covered with granules and abundant thallic conidia (arthroconidia), with both schizolytic and rhexolytic secession.
