Cryptococcus vishniacii

Cryptococcus vishniacii is a fungus species. It consists of 98 un-described imperfect yeast isolated from soil samples in the Antarctica. While all of the isolated samples where greater than 90% similar to each other they were also less than 90% similar to other yeast species. This species grows at 4 degrees Celsius and below but not at 26 degrees Celsius and above. Visually it is characterized as a cream colored mass, lacking psedomycelia. It is nonfermentative and uses glucose, maltose, melezitose, trehalose, and xylose.[1]
