Pichia anomala (E. C. Hansen) Kurtzman, Antonie van Leeuwenhoek 50, 209-217. 1984.

 Description: Growth on YM agar: After 7 days at 25°C: Colony white, butyrous. After 3 days at 25°C, cells spheroidal to elongate, 2.0-5.0 × 3.0-6.0 μm, and growing singly, in pairs, or in small clusters. Dalmau plate culture on Corn Meal Agar: Pseudohyphae consist of chains of ovoidal or cylindroidal cells. Formation of ascospores: Strain ST3-1d formed asci that contained 2 to 4 hat-shaped ascospores on McClary's acetate agar after 7 days. It should be sporogenous diploid.

 Note: Kurtzman (2000) reported that P. anomala is heterothallic, but the sporogenous diploid form is usually isolated from nature and diploid cells directly convert to asci and form 1 to 4 hat-shaped ascospores.
