Relationships among the genera Ashbya, Eremothecium, Holleya and Nematospora determined from rDNA sequence divergence

Abstract

Species of the genera Ashbya, Eremothecium, Holleya, and Nematospora were compared from extent of divergence in a 580-nucleotide region near the 5′ end of the large subunit (26S) ribosomal DNA gene. The four genera are closely related and comprise a subclade of the hemiascomycetes. Because the taxa show little divergence, it is proposed that all be placed in the genus Eremothecium. The family Eremotheciaceae, fam. nov., is proposed. © 1995 Society for Industrial Microbiology.
