Cryolevonia A. Pontes, Ruethi, B. Frey & J.P. Samp. 2020, in Pontes et al., International journal of systematic and evolutionary microbiology 70(4), 2334-2338. (2020)

Etymology: (Cry.o.le.vo'ni.a. Gr. neut. n. kryos icy cold, frost, refers to the cryophilic nature of this yeast; N.L. fem. n. levonia refers to levon / levonis, a designation for ‘yeast’ in the Romanic/Italic dialect of the inhabitants in mountain region where the yeast was originally found; N.L. fem. n. Cryolevonia).

Diagnosis: The genus is circumscribed by the phylogenetic analyses shown in Figure 1 having therefore as closest relatives the genera Camptobasidium and Glaciozyma of the family Camptobasidiaceae. Sexual reproduction is not known. Cells divide by budding. Hyphae and pseudohyphae can be formed and globose, teliospore-like structures can be observed on aged cultures. Basidia have not been observed. Ballistoconidia are not formed. The genus is ecologically adapted to cold habitats and is psychrophilic with maximum growth temperatures below 20 °C.
