Cladosporium spp. (Cladosporiaceae) isolated from Eucommia ulmoides in China

Abstract

Eucommia ulmoides is a rare tree species in China with high medicinal and gum value. Nine strains of hyphomycetous fungi were isolated from the leaf litter of E. ulmoides in Guizhou Province. Preliminary identifications based on ITS indicated that they belong to the genus Cladosporium. Morphology and phylogenetic analyses based on the internal transcribed spacer regions (ITS) of the nrDNA, the partial translation elongation factor 1-α (tef1) gene and partial of actin (act) gene confirmed that the strains represent four species, including two novel taxa, viz., Cladosporium eucommiae and C. guizhouense and two new substrate records for known species.
