Abstract

In the family Saccharomycetaceae, the genus Eremothecium Borzi emend. Kurtzman included the five species that were on the whole characterized by the complex distribution of isoprenoid quinone homologues (Q-5, Q-6, Q-7 and Q-9) as well as of needle-shaped ascospore ornamentation. However, the calculated pair-wise sequence similarities among the five species were very low (94.7 - 96.5%) in the 26S rRNA gene D1/D2 domain sequences and so on. The experimental data obtained indicated that the emended genus was not taxonomic homogeneous- but heterogeneous-natured, indicating that the five species should be accommodated to their own separate five genera as Eremothecium cymbalariae, Nematospora coryli, Ashbya gossypii, Crebrothecium ashbyi and Holleya sinecauda.
