Tilletiopsis derxii, Tilletiopsis oryzicola and Tilletiopsis penniseti, three new species of the ustilagionomycetous anamorphic genus Tilletiopsis isolated from leaves in Thailand.
Four strains of ballistoconidium-forming yeast-like fungi (K-95, K-125, K-132 and K139), isolated from plants collected in Bangkok, Thailand, were assigned to the genus Tilletiopsis based on morphological and chemotaxonomical characteristics. On the basis of sequence data of 18S rDNA and the D1/D2 region of 26S rDNA, strains K-95, K-125 and K-132 were close to T. flava and T fulvescens, and strain K-139 each formed related to T. minor. DNA-DNA reassociation experiments with related species revealed that strains K-125, K-132 and K-139 each formed a new and distinct species whereas strain K-95 was identified as T. flava. Tilletiopsis derxii Takashima et Nakase sp. nov. (JCM 10217T; K-125), Tilletiopsis oryzicola Takashima et Nakase sp. nov. (JCM 10218T; K-132), and Tilletiopsis penniseti Takashima et Nakase sp. nov. (JCM 1021 6T; K- 139) are the names proposed for the new taxa.
