Four new species of Metschnikowia and the transfer of seven Candida species to Metschnikowia and Clavispora as new combinations.

From comparisons of ITS1-5.8S-ITS2 and gene sequences for nuclear D1/D2 LSU rRNA, nuclear SSU (18S) rRNA, translation elongation factor 1-α (EF1-α) and RNA polymerase II subunit 2 (RPB2), the following four new ascosporogenous yeast species were resolved and are described as Metschnikowia anglica (NRRL Y-7298 [type strain], CBS 15342, MycoBank MB 823167), Metschnikowia leonuri (NRRL Y-6546, CBS 15341, MB 823166), Metschnikowia peoriensis (NRRL Y-5942, CBS 15345, MB 823164) and Metschnikowia rubicola (NRRL Y-6064, CBS 15344, MB 823165). The following six species of Candida are members of the Metschnikowia clade and are proposed for transfer to Metschnikowia as new combinations: Candida chrysomelidarum (NRRL Y-27749, CBS 9904, MB 823223), Candida gelsemii (NRRL Y-48212, CBS 10509, MB 823192), Candida kofuensis (NRRL Y-27226, CBS 8058, MB 823195), Candida picachoensis (NRRL Y-27607, CBS 9804, MB 823197), Candida pimensis (NRRL Y-27619, CBS 9805, MB 823205) and Candida rancensis (NRRL Y-48702, CBS 8174, MB 823224).

Description of Teunomyces gen. nov. for the Candida kruisii clade, Suhomyces gen. nov. for the Candida tanzawaensis clade and Suhomyces kilbournensis sp. nov.

DNA sequence analysis has shown that species of the Candida kruisii clade and species of the C. tanzawaensis clade represent phylogenetically circumscribed genera, which are described as Teunomyces gen. nov.

Occultifur kilbournensis f.a. sp. nov., a new member of the Cystobasidiales associated with maize (Zea mays) cultivation.

During a study of microorganisms associated with maize (Zea mays) cultivation, yeasts were isolated from overwintered stalks, cobs and surrounding soil, which were collected from an agricultural field in south-central Illinois, USA. Predominant among isolates were two species of Cryptococcus (Cr. flavescens, Cr.

Description of Kuraishia piskuri f.a., sp. nov., a new methanol assimilating yeast and transfer of phylogenetically related Candida species to the genera Kuraishia and Nakazawaea as new combinations.

The new anamorphic yeast Kuraishia piskuri, f.a., sp.

Three new anascosporic genera of the Saccharomycotina: Danielozyma gen. nov., Deakozyma gen. nov. and Middelhovenomyces gen. nov.

Three new non-ascosporic, ascomycetous yeast genera are proposed based on their isolation from currently described species and genera. Phylogenetic placement of the genera was determined from analysis of nuclear gene sequences for D1/D2 large subunit rRNA, small subunit rRNA, translation elongation factor-1α and RNA polymerase II, subunits B1 and B2. The new taxa are: Deakozyma gen.
