　Description： Colony diameters on Czapek’s Agar 2.0-3.0 cm in 10 days at 25°C, wrinkled; conidial heads radiate, yellowish green, olive-ocher or grayish olive to deep grayish olive (R., Plate XXX, XLVI); mycelium white, light buff, seashell pink to pale flesh color (R., Plate XV, XIV); soluble pigment clear to red brown; reverse uncolored, light salmon-orange to grenadine pink or near dull ox-blood red to dull victoria lake (R., Plate II, I); exudate colorless to pale capucine buff (R., Plate III); stipes 80-700 × 3.2-9.5 μm, colorless to pale yellow brownish, thick-walled, smooth, brittle; vesicles 6.0-22.2 μm in diameter, pyriform, spathulate, obovoid, subglobose. Aspergilla biseriate, metulae 3.2-10.3 × 2.4-6.4 μm, covering 1/2 to the entire surface of the vesicle; phialides 3.6-9.5 × 2.0-3.2 μm. Conidia subglobose to ellipsoidal or globose, smooth to conspicuously roughened, 2.4-5.0 μm in diameter. Colony diameters on Malt Extract Agar 2.0-2.4 cm in 10 days at 25°C, plane; conidial heads radiate, celandine green or pea green to sage green (R., Plate XLVII); mycelium white; soluble pigment indistinct red brown; reverse near pale ochraceous-buff to cinnamon-brown (R., Plate XV).

　Note： A. asperescens, A. sydowii and A. versicolor, either in growth rate or colony characteristics, are quite similar to each other. However, A. sydowii colonies are velutineous, color tended to be distinctively blue. Conidia surface ornamentations in A. asperescens are rough whereas A. versicolor are rough to spinose.
