title: Cryptococcus friedmannii, a new species of yeast from the Antarctic.
abstract: Cryptococcus friedmannii Vishniac sp. nov. from an Antarctic cryptoendolithic community is a psychrophilic basidioblastomycete characterized by cream-colored colonies of cells with smooth, layered walls, budding monopolarly, producing amylose and extracellular proteinase, utilizing nitrate and D-alanine (inter alia) as nitrogen sources and L-arabinose, arbutin, cellobiose, D-glucuronate, maltose, melezitose, salicin, soluble starch, trehalose, and D-xylose as carbon sources.  This species differs from all other basidiomycetous yeasts in possessing the following combination of characters:  amylose production (positive), assimilation of cellobiose (positive), D-galactose (negative), myo-inositol (negative),  D-mannitol (negative), and sucrose (negative).
