Conidiophore | : | Arising from the surface of the agar or from aerial hyphae, 50-100 μm long, smooth, typically branched along the length in a verticillate fashion. |
Phialides | : | Divergent from point of attachment to the conidiophore, straight, tapering slightly from base to tip, 9-15 μm long, 2.5-3.9 μm wide in the middle, 2.5-3.0 μm wide at the base; periclinal thickening visible at the tip. |
Conidia | : | Green, typically clavate to ellipsoidal or subglobose, often with a truncate or slightly protuberant base, 3.5-5 χ 2.5-3 μm, L/W 1.4-1.8, smooth, held in drops of pale green to colorless, watery liquid. |
Chlamydospores | : | Chlamydospore produced abundantly, globose to subglobose. |
Stromata | : | Solitary to gregarious, 1-5 mm diam circular to elliptic in outline, centrally but broadly attached, at first yellow but becoming slightly rufous with age |
Ascospores | : | Green, more or less monomorphic and subglobose, thick walled, warted, distal part (2.5-)3.5-4.0 χ (3.0-)3.3-3.7(-4.07) μm, proximal part (2.8-)3.0-4.0(-5.0) χ (2.2-)2.7-3.7(-4.0) μm. |
