Abstract

The majority of species have been isolated from fungus-feeding insects and particularly from the gut of beetles. In the present study, seven yeast strains were isolated from the gut of species feeding on gleba, the spore-bearing inner mass, of a stinkhorn mushroom belonging to the family . Based on phenotypic, biochemical characterization and sequence analysis of the D1/D2 region of the large subunit rRNA gene and the internal transcribed spacer (ITS) region, two of these yeast strains, DGY3 and DGY4, represented a novel species of the genus . The novel species is closely related to an undescribed species of ST-370 (DQ404513) and with wherein, the novel species differs from by 40 nucleotide substitutions and three gaps (7.7 % sequence variation) in the D1/D2 region and 50 nucleotide substitutions and seven gaps (13.7 % sequence variation) in the ITS region. Several morphological and physiological differences were also observed between and the strains obtained during this study. These data support the proposal of as a novel species, with DGY3 as the holotype and CBS 16329 and MCC 1871 as ex-type strains.
