Abstract

Trichoderma viridescens is recognized as a species complex. Multigene analyses based on the translation elongation factor 1-alpha encoding gene (tef1), a part of the rpb2 gene, encoding the second largest RNA polymerase subunit and the larger subunit of ATP citrate lyase (acl1) reveals thirteen phylogenetic species with little or no phenotypic differentiation. Acl1 is used here for the first time in Trichoderma phylogenetics. The typification of T. viridescens sensu stricto is clarified and Hypocrea viridescens is replaced by the new name T. paraviridescens. Besides these two species, eleven are phylogenetically recognized and Trichoderma olivascens, T. viridarium, T. virilente, T. trixiae, T. viridialbum, T. appalachiense, T. neosinense, T. composticola, T. nothescens and T. sempervirentis are formally described and illustrated. Several species produce yellow diffusing pigment on CMD, particularly after storage at 15 °C, while T. olivascens is characterized by the formation of an olivaceous pigment. The results are compared with earlier publications on this group of species.
