Colonies on Sabouraud dextrose agar at 25°C are grayish white to yellowish, dull to shiny, and smooth to wrinkled. The two varieties are distinguished by maximum growth temperature. Debaryomyces hansenii var. hansenii has a maximum growth temperature of 35°C while D. hansenii var. fabryi has a maximum growth temperature of 40°C and no growth on cycloheximide. This species is not distinguishable from several other species on Chromager Candida [1069].
On cornmeal following 72 hours incubation at 25°C, usually no pseudohyphae are evident. Rare strains have rudimentary to well-developed pseudohyphae.
Candida famata is an emerging pathogen that has been reported to have decreased susceptibility to amphotericin B [1775], [1776]. This species has been recovered from psoriasis, nails, and wounds [1270], the blood in a stem cell transplant patient [2347], and from the retina [382].
