The surface is white, pale pink or yellow at the beginning and becomes brown to black and velvety with a grayish fringe by aging. Reverse is pale or black. By aging, while the colony gets black and velvety, hyphae become visible. Blastoconidia are pale in color. The synchronous development of blastoconidia in tufts is typical.
Hyphae are septate.
They appear hyaline at the beginning and get dark brown by aging. Conidiogenous cells, which are not much differentiated, are either intercalary or located terminally in the hyphae. They form clusters or are located along the hyphae. These conidia continue to multiply by budding and form secondary blastoconidia. As well as blastoconidia, chlamydoconidia and arthroconidia may also be observed.
