Phylogeny of the genus Trichoderma and occurrence of the most common species. Phylogeny of Trichoderma based on Bayesian analysis of the rpb2 gene (see Methods for details). Only species with major abundance (> 100 nucleotide sequences deposited in NCBI GenBank, April 2018,) are shown. The number of core nucleotide sequences deposited in GeneBank is indicated by the size of the filled circles with T. pleuroticola, N = 103 being the smalles shown. Sections Longibrachiatum and Trichoderma and the Harzianum/Virens clade are indicated by colored vertical bars. Rare Trichoderma spp. (< 100 nucleotide sequences known in public databases) are not shown. Circles for T. reesei and T. viride likely represent false positive values as T. reesei is most studied species, while T. viride is the oldest Trichoderma species name that was assigned to all strains before DNA barcoding became available
