Abstract

A new species of Trichoderma, Trichoderma guizhouense, isolated from soil in Guizhou Province, is described based on morphology and phylogenetic analyses. This species exhibits characteristic Trichoderma morphology but is distinct from related species based on characters of phialides and conidia. Two DNA markers, the translation elongation factor 1 alpha (tef1) and RNA polymerase II subunit b (rpb2) were used for phylogenetic analyses. The correlation between morphological and molecular-based clustering demonstrated two studied isolates are a new species.
