 Description: Growth in glucose-yeast extract-peptone broth: After 3 days at 25°C, the cells are ellipsoidal to cylindrical, (2.4-4.0) × (4.0-8.8) µm, single, in pairs, and cluster, multilateral budding. Growth on glucose-yeast extract-peptone agar: Aerobic growth is cream-white to dark-red, butyrous, rough or smooth, dull and convex with undulate margin. Dalmau plate culture on corn meal agar: After 7 days at 25°C, growth under the coverglass generally shows moderately pseudohyphae. Ascus and ascospores may form from cell of pseudohyphae. True hyphae are not produced. Formation of ascospores: After 7 days in Kleyn’s medium, one to four spores are formed per ascus. Ascus is evanescent and spore is spheroidal. The strains examined appear homothallic.
