Pichia ohmeri (Etchells & T. A. Bell) Kreger-van Rij., Thesis. University of Leiden, the Netherlands 1964.

Synonym: Trichosporon arenicola de lima & Aciole de Queiroz 1972.

 Description: Growth on YM agar: After 7 days at 25°C: Colonies grayish-white, and nearly smooth to finely convoluted. Margins irregularly lobed. After 3 days at 25°C, the cells ovoidal to cylindroidal, 2.0-5.0 × 2.5-7.5 μm, single, in pairs and in short chains. Reproduction by budding. Dalmau plate culture on Corn Meal Agar: Pseudohyphae consist of chains of ovoidal or cylindroidal cells, and sometimes bear small verticals of ovoidal blastoconidia. Formation of ascospores: Strain ST5-3 did not form asci on McClary's acetate agar after 10 days. It should be haploid form.

 Habitat: river water; cucumber brine; pleural fluid; gooseberry jelly; sambal ulak; flowers.

 Note: Kurtzman (2000) reported that P. ohmeri is a heterothallic species that normally isolated in the haploid form and require conjugation of complementary mating types before sporulation. The diploid strains which form unconjugated asci are infrequently isolated.
