Cryptococcus socialis sp. nov. and Cryptococcus consortionis sp. nov., Antarctic basidioblastomycetes

New yeasts from the Ross Desert (dry valley area) of Antarctica include Cryptococcus socialis sp. nov. and Cryptococcus consortionis sp. nov. Cryptococcus socialis MYSW A801-3aY1 (= ATCC 56685) requires no vitamins, assimilates L-arabinose, cellobiose, D-glucuronate, maltose, melezitose, raffinose, soluble starch, sucrose, and trehalose, and may be distinguished from all other basidioblastomycetes by the combination of amylose production, cellobiose assimilation, and failure to utilize nitrate, D-galactose, myo-inositol, and mannitol. Its guanine-plus-cytosine content is 56 mol%. Cryptococcus consortionis MYSW A801-3aY92 (= ATCC 56686) requires thiamine, assimilates L-arabinose, D-glucuronate, 2-ketogluconate, salicin, succinate, sucrose, trehalose, and D-xylose, and may be distinguished from all other basidioblastomycetes by the combination of amylose production and failure to utilize nitrate, cellobiose, D-galactose, myo-inositol, and mannitol. Its guanine-plus-cytosine content is 56 mol%.

Cryptococcus friedmannii, a new species of yeast from the Antarctic

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).
