Description :Aspergillus versicolor (Vuill.) Tiraboschi
Colonies on Czapek agar at 25°C attaining a diameter of 1.0-1.5 cm within 7 days, often poorly sporulating after one week but richer after 14 days, either consisting of a dense felt of conidiophores or of aerial and closely interwoven mycelium bearing the conidiophores. Colour at first white, then changing to yellow, orange-yellow to yellow-green, often intermixed with flesh to pink colours. Conidiophores hyaline or slightly pigmented, smooth-walled. Vesicles subglobose to ellipsoidal, 12-16 µm in diam. Phialides borne on metulae, 5.5-8.0 x 2.5-3.0 µm. Metulae 5.0-7.5 x 2.0-2.5 µm.
Conidia globose, 2-3.5 µm in diam, echinulate. Hülle cells sometimes present.
Colonies on MEA growing faster and with less aerial mycelium. Colour mostly in darker green shades.
Good growth on CREA.
Important (toxic) metabolites: sterigmatocystin, nidulotoxin.
Habitat: food, indoor
Common on cheese, cereals, soil, (ground)nuts, spices, dry meat products. The species is very common in indoor environments (Samson and Hoekstra, 1994). Isolates may produce pronounced earthy volatiles. The colony pattern and diameter of indoor isolates may vary, but the micromorphology is often similar.
