Fifty four Trichoderma strains were isolated from soil samples collected garlic and onion crops in eight different sites Brazil identified using phylogenetic analysis based on combined ITS region, tef1-α, cal, act rpb2 sequences. The genetic variability of the recovered species was analysed by AFLP their phenotypic determined MALDI-TOF. strain clusters both typing techniques coincided with taxonomic determinations made analysis. showed occurrence asperellum, asperelloides, afroharzianum, hamatum, lentiforme, koningiopsis, longibrachiatum erinaceum, samples. We also describe two new species, harzianum clade section Pachybasium, which we have named azevedoi sp. nov. peberdyi examined T. (three strains) (12 display significant genotypic variability, but form monophyletic clades strong bootstrap posterior probability support are morphologically distinct respective most closely related species.
