Colonies growing slowly or rapidly depending on the species, aerial mycelium
usually limited, floccose to arachnoid; reverse colourless to dull yellowish. Some
isolates with a distinctive aromatic odour resembling coconut. Conidiation variably
effuse, loosely tufted, or forming compact pustules; white at first, eventually
green (rarely brown). Chlamydospores present in most isolates, frequently abundant.
Conidiophores usually relatively narrow and flexuous; with primary branches
arising at regular intervals, usually paired or in whorls of three, usually short and
not extensively rebranched. Phialides mostly in verticils of 2 or 3, in some strains
up to 5-verticillate, lageniform to subulate. Conidia green (rarely brownish), smoothwalled
to distinctly verrucose, subglobose to obovoid or ellipsoid.
