Colonies are fast growing, suede-like to downy, white to pale yellow in colour, becoming pinkish brown, red, green or yellow with a colourless, yellow or reddish brown reverse. Conidiophores are usually well differentiated and erect, verticillately branched over most of their length, bearing whorls of slender awl-shaped divergent phialides. Conidia are hyaline or brightly coloured, mostly one-celled, and are usually borne in slimy heads (glioconidia).
