Colonies on potato dextrose agar at 25°C are white to yellow to drab gray to brown, but never green. Gray is the most common color. Reverse yellow to brown with a yellow diffusing pigment. Exudate, when present, is clear to yellow to purplish-brown. Rapid growth. Texture is woolly to cottony to somewhat granular.
Hyphae are septate and hyaline. Conidial heads are radiate to loosely columnar and biseriate. Conidiophores 30-350 µm, smooth-walled, and brown. Vesicles are globose to subglobose, 7-16 µm in diameter. Metulae and phialides cover the upper portion of the vesicle. Conidia are globose, 3-4.5 µm, with very rough walls. Hülle cells, irregular to elongate in shape, should be searched for, and may be light dependent[531, 1215, 1875, 2202].
This species has been reported as an agent of fungal endocarditis on a prosthetic valve, primary cutaneous disease in immunosuppressed patients , , , , and invasive disseminated disease, , , , and. Strains have been differentiated by random amplification of polymorphic DNA .
