 Description: Growth in glucose-yeast extract-peptone broth: After 3 days at 25°C, the cells are ovoid , subglobose to ellipsoidal, (3.2 –6.4) × (4.0-8.0) µm, single, in pairs, in short chains and clusters, multilateral budding. Sediment is formed, but pellicle is absent. Growth on glucose-yeast extract-peptone agar: Aerobic growth is cream, butyrous, smooth, and glossy. Margin pulvinate with undulate or convex with entire. Dalmau plate culture on corn meal agar: After 7 days at 25°C, hyphae are absent, rudimentary pseudohyphae are formed or not. Formation of ascospores: Ascus is formation by cell conjugation. One to four spores are formed per ascus. The spore is globose, spheroidal and smooth. The species appears homothallic.
