Mrakia is a genus of fungi in the order Cystofilobasidiales.[1] The genus comprises yeasts, some of which have a hyphal state forming teliospores from which basidia arise. Mrakia species are typically psychrophilic, many originally isolated from glaciers and frigid environments,[2][3] and are capable of low-temperature fermentation, making them of potential interest in brewing[4] and bioremediation.[5]

The genus was named after the American microbiologist Emil M. Mrak.[6]

The genus Mrakiella was proposed for the anamorphic (yeast) state of Mrakia. Following changes to the International Code of Nomenclature for algae, fungi, and plants, however, the practice of giving different names to teleomorph and anamorph forms of the same fungus was discontinued, meaning that Mrakiella became a synonym of the earlier name Mrakia.[1]
