Ascomycota microfungi multi-gene phylogeny taxonomy tropical area Fungi

Abstract

A new species of microfungus, described herein as Trichoderma thailandense was isolated from the pileus surface of oyster mushroom and upland black rice samples in Thailand. This species is described using morphological characteristics and molecular multi-gene analyses. Based on multi-gene phylogenetic analyses of the internal transcribed spacer (ITS) region of the rDNA, RNA polymerase subunit II gene sequences (rpb2), and translation elongation factor 1-α (tef1-α) gene revealed that the position of T. thailandense is well-supported within Harzianum clade of the genus Trichoderma, but distinct from other all other known species. A full description, illustrations and a phylogenetic tree showing the position of T. thailandense are provided.
