Abstract

Two new species of the yeast genus were isolated from frass obtained from loblolly pines growing in Mississippi. The new taxa, designated and , are heterothallic, and var. proved to be a haploid member of the latter species. The species show interspecific mating, but ascospores from the crosses are infertile. The nuclear deoxyribonucleic acids from the species differ by 2 mol% in guanine plus cytosine content and exhibit low (25%) base sequence complementarity. Deoxyribonucleic acid relatedness was determined spectrophotometrically, and the methodology is given in detail.
