In the family Mrakiaceae, the type genus Mrakia senseu stricto included the five teleomorphic species with the type species, Mrakia frigida. In contrast, the anamorphic genus Mrakiella sensu stricto did the 10 species with the type species, Mrakiella cryoconiti. Between the two genera, the completely separated clusters were shown in the phylogenetic tree (LSU D1/D2) derived from the MP method. The pair-wise sequence similarity between Mrakia frigida and Mrakiella cryoconiti and Mrakiella aquatica were 98.2% and 96.8%. The calculated pair-wise sequence similarities were 100-99.3% among the five Mrakia species and were 97.1% between Mrakiella cryoconiti and Mrakiella aquatica. The teleomorphic genus Krasilnikovozyma emend. contained the three species with the type species, Krasilnikovozyma curviuscula. Thus, the two teleomorphic genera were taxonomic homogeneous-natured, and the three were characteristic of Q-8.
