Two new Trichoderma species (Hypocreales, Hypocreaceae) isolated from decaying tubers of Gastrodia elate
Species of Trichoderma are widely distributed around the world. In this study, two new species in Trichoderma, named as T. albidum and T. variegatum, were introduced and illustrated. These species were isolated from diseased tubers of Gastrodia elata in China and identified based on morphological ch...

| description | Species of Trichoderma are widely distributed around the world. In this study, two new species in Trichoderma, named as T. albidum and T. variegatum, were introduced and illustrated. These species were isolated from diseased tubers of Gastrodia elata in China and identified based on morphological characteristics and multi-gene sequence analyses of three loci that is the internal transcribed spacer regions of the ribosomal DNA (ITS), the translation elongation factor 1-α encoding gene (tef1-α) and the gene encoding the second largest nuclear RNA polymerase subunit (rpb2). Distinctions between the new species and their close relatives were discussed. According to results of the phylogenetic analyses, T. albidum belonged to the Harzianum clade and T. variegatum are grouped with species of the Spirale clade. The expansion of two clades provided research foundations for the prevention and control of tuber diseases in G. elata. |
