Psychromyces

Psychromyces L. Perini & Zalar, in L. Perini, et al., International Journal of Systematic and Evolutionary Microbiology 71 (2, no. 4655): 15 (2021)

Etymology:  Psychromyces (Psy. chro. my’ces. Gr. masc. ad. psychros cold; Gr. masc. n. mykes a fungus; N.L. masc. n. Psychromyces a fungus from the cold).

Diagnosis: Belongs to phylum Basidiomycota, subphylum Pucciniomycotina, class Microbotryomycetes, family Camptobasidiaceae. The genus is circumscribed based on phylogenetic analyses shown with close relationships to the genera Camptobasidium, Glaciozyma and Cryolevonia.

Cultures pink, dimorphic or filamentous, initially yeast-like, after incubation filamentous with some or no remaining yeast colonies. Hyphae septate, clamp connections absent or present. Oblong intercalary teliospores produced after 1 month of incubation. Sexual reproduction in the form of germinating basidia from teliospores and basidiospores is not known, but clamped hyphae indicate its sexual reproduction.

Assimilated C sources: α-d- glucose, sucrose, raffinose and melezitose. Assimilated N sources: nitrate, nitrite and cadaverine. Glucose is not fermented. Urease reaction is positive.

Index Fungorum Number: IF 834189.

Type species: Psychromyces glacialis L. Perini & Zalar, in L. Perini, et al., International Journal of Systematic and Evolutionary Microbiology 71 (2, no. 4655): 15 (2021)
