Four new species of Trichoderma in the Harzianum clade from northern China.

ABSTRACT: The Harzianum clade of Trichoderma comprises many species, which are associated with a wide variety of substrates. In this study, four new species of Trichoderma, namely T. lentinulae, T. vermifimicola, T. xixiacum, and T. zelobreve, were encountered from a fruiting body and compost of Lentinula, soil, and vermicompost. Their colony and mycelial morphology, including features of asexual states, were described. For each species, their DNA sequences were obtained from three loci, the internal transcribed spacer (ITS) regions of the ribosomal DNA, the gene encoding the second largest nuclear RNA polymerase subunit (RPB2), the translation elongation factor 1-α encoding gene (TEF1-α). The analysis combining sequences of the three gene regi
