Abstract

During a survey of saprobic fungi associated with the medicinal plant Phellodendron amurense in Guizhou Province, China, three taxa were isolated and examined. Based on morphological characteristics and multigene phylogenetic analyses, two novel species, Dictyosporium phellodendri (Dictyosporiaceae, Pleosporales) and Helicosporium phellodendri (Tubeufiaceae, Tubeufiales), are proposed. In addition, Neohelicomyces guizhouensis (Tubeufiaceae, Tubeufiales) is reported as a new host record. Detailed morphological descriptions, illustrations and molecular evidence are provided to support the establishment of these taxa.
