Growth on YM agar: After 7 days at 25°C: Colonies grayish to cream-colored, dull, soft, winkled. After 3 days at 25°C, cells ovoidal to cylindroidal, 2.0-3.5 × 3.0-5.0 μm, single, in pairs and chains, reproduction by budding. Dalmau plate culture on Corn Meal Agar: Pseudohyphae consist of chains of ovoidal or cylindroidal cells, sometimes bear small verticals of ovoidal blastoconidia. Formation of ascospores: Strain ST3-5 was homothallic and formed asci that contained 2 hat-shaped ascospores on McClary's acetate agar after 7 days without conjugation of complementary mating types.

Note：
Phaff et al. (1987) reported that most strains of P. kluyveri are heterothallic with 2 to 4 hat-shaped spores in each ascus. But some, including the two-spored strains, appear homothallic.
