Abstract

In the family Eremotheciaceae, the only genus Eremothecium emend. Kurtzman included five species. However, the calculated pair-wise sequence similarities were very low (93.8-96.8%) among the five species, indicating that the emended genus was not taxonomic homogeneous-natured. Therefore, it is adequate to accommodate the five species to their own separate five genera.
