Cryolevonia schafbergensis

Cryolevonia schafbergensis A. Pontes, J. Ruethi, B. Frey, A. Aires, A. Thomas, D. Overy, B. Halti, R. Kerr & J.P. Sampaio 2020, in Pontes et al., International journal of systematic and evolutionary microbiology 70(4), 2334-2338. (2020)

Etymology: Cryolevonia schafbergensis (schaf.berg.en'sis. N.L. fem. adj. schafbergensis pertaining to Schafberg, the name of a mountain area located up to Pontresina in the upper Engadine valley in Switzerland, where the type strain was isolated).

Diagnosis: After 2 weeks on YM agar at 8 °C cultures have a light pink colour and have a butyrous texture. After 2 weeks of growth on YM agar at 8 °C, cells are elongated (614×23 μm) (Figure 2) and proliferation is done by budding at the distal ends of the cell. On Dalmau plates after 4 weeks at 8 °C, rudimentary pseudohyphae are present but true hyphae are not formed. On potato dextrose agar incubated at 8 °C for 8 weeks inconspicuous stretches of narrow hyphae of approximately 1 μm in diameter and devoid of clamp connections are formed. Occasionally globose to sub-globose teliospore-like structures measuring 610 μm in diameter can be observed on the hyphae. The induction of germination of the teliospore-like structures was unsuccessful, even after a prolonged resting stage of 12 weeks in demineralized water kept at 4 °C.
