Description: | Growth in glucose-yeast extract-peptone broth: After 3 days at 25°C, the cells are ovoidal to ellipsoidal, (2.0 –6.0) × (3.0-9.0) µm, single, in pairs, in short chains and clusters, multilateral budding. Sediment is formed. Growth on glucose-yeast extract-peptone agar: Aerobic growth is cream, butyrous, smooth or rough, glossy or dull and convex with entire or crenate margin. Dalmau plate culture on corn meal agar: After 7 days at 25°C, growth under the coverglass show branched, but not poorly differentiated pseudohyphae. True hyphae are not found. Formation of ascospores: Asci are persistent and form one to four spheroidal to ovoidal ascospores. Ascosporulation may be preceded by cell conjugation. | |||
