Easily recognized by its nearly spherical spores (conidia) that are several-celled and strongly roughened. The conidia are usually produced in dense masses from clustered conidiophores (sporodochia). Identification may be difficult at first because isolates often fail to produce conidia in culture. Experienced mycologists easily recognize it by its fast-growing, red, orange or yellow colonies. Heavily sporulating colonies are sometimes encountered but these are less common than the more lightly sporulating or non-sporulating strains. Very common on dead or dying plants; frequently isolated from both outdoor and indoor air.
