Abstract

In the course of two independent studies three yeasts have been isolated from temperate deciduous trees in Hungary and Germany. Analyses of nucleotide sequences of D1/D2 domains of the 26S rRNA gene (LSU) suggested that these strains belong to the Meyerozyma clade in Debaryomycetaceae (Saccharomycetales). The phylogenetic analysis of a concatenated alignment of the ITS region and LSU gene sequences confirmed the placement of the three strains in the Meyerozyma clade close to Candida elateridarum. If mixed in proper combinations, the strains formed one to two hat shaped ascospores in deliquescent asci. In addition to the ascospore formation, the three studied strains differed from Candida elateridarum and other members of the Meyerozyma clade in terms of ribosomal gene sequence and some physiological properties. To accommodate the above-noted strains, we describe the new species as Meyerozyma amylolytica sp. nov. (holotype: DSM 27310T; ex-type cultures: NCAIM Y.02140T=MUCL 56454T, allotype: NCAIM Y.01955A; ex-allotype culture: DSM 27468), MB 821663. Additionally, we propose the transfer of five non-ascosporic members of the Meyerozyma clade to the genus Meyerozyma as the following new taxonomic combinations Meyerozyma athensensis f.a., comb. nov. (MB 821664), Meyerozyma carpophila f.a., comb. nov. (MB 821665), Meyerozyma elateridarum f.a., comb. nov. (MB 821666), Meyerozyma neustonensis f.a., comb. nov. (MB 821667), and Meyerozyma smithsonii f.a., comb. nov. (MB 821668).
