Colonies. On Czapek's agar, growing restrictedly attaining 2 cm diam. after 7 days at 25°C, surface floccose, margin yellowish, changing into brownish towards the centre; reverse yellowish at the margin, grey-brown at the centre, with faintly yellowish secretion diffusing into the surrounding agar; on Czapek's agar + 50% sucrose, growing rapidly attaining 8 cm diam. after 7 days at 25°C, surface floccose, margin thin, whitish, shifting to yellow group, then to yellow-orange at the centre, intermixed with the greenish colour of conidial heads; reverse yellow. Conidiophores. Abundant up to 500 μm or more long; vesicles globose to subglobose, 12-15 μm diam. or more; conidial heads radiate. Conidiogenous cells. Arising directly from the vesicles, 7.5-9.2 × 3.3-4.2 μm. Conidia. Ovate to broadly elliptical with ends often flattened, spinulose under light microscope and lobate-reticulate under SEM, 4.5-5.5 μm long, produced in persistent chains. Ascomata. Abundant, enveloped in orange hyphae, globose to subglobose, up to 130 μm diam., maturing in 7-10 days. Asci. 7.5-11.0 μm. Ascospores. Lenticular, convex wal1s smooth or very faintly roughened under LM, with prominent thin, often recurved equatorial ridges, and a furrow, 3.7-4.5 × 3.3-3.7 μm.

Aspergillus chevalieri is a species of fungus in the genus Aspergillus. It is from the Aspergillus section. The fungi in the Aspergillus section are known for their ability to grow at extremely low water activities. The species was first described in 1926. It has since been reported as an opportunistic pathogen causing skin infections.

The genome of A. chevalieri was sequenced as a part of the Aspergillus whole-genome sequencing project - a project dedicated to performing whole-genome sequencing of all members of the genus Aspergillus. The genome assembly size was 26.41 Mbp.
