Abstract
Two novel yeast species, Asterotremella meifongana sp. nov. and Asterotremella nantouana sp. nov., belonging to Asterotremellaceae within the Trichosporonales, are proposed to accommodate five strains isolated from Taiwanese samples of soil and basidiocarps during 2006-2007. Sequence analysis of the D1/D2 domains of the large subunit rRNA gene revealed that the two species are phylogenetically closely related to species of the genus Asterotremella, which indicates that they are members of the genus. The two species can be further differentiated from other Asterotremella species based on their internal transcribed spacer sequences, as well as on a few physiological test responses. The type strains are A. meifongana SN4S04(T) (=CBS 11424(T) = BCRC 23196(T)) and A. nantouana SN5S06(T) (=CBS 10890(T) = BCRC 23135(T)).
