　Description： Colony diameters on Czapek’s Agar 3.0-3.5 cm in 10 days at 25°C, wrinkled; conidial heads spherical, or splitting into compact divergent columns, cream color, pinkish buff or near dark olive-buff (R., Plate XVI, XXIX, XL); mycelium white, inconspicuously floccose to floccose; exudate uncolored; reverse dull yellow brown to victoria lake (R., Plate I); soluble pigment, pale capucine buff (R., Plate III); stipes 360-1390 × 4.0-16.0 μm, pale yellow to light yellow brown, slightly to coarsely roughened; vesicles spherical to subspherical, 8.8-46.0 μm in diameter. Aspergilla biseriate, metulae covering the entire surface of the vesicle, 4.8-33.3 × 2.4-10.3 μm; phialides 5.6-143.0 × 1.8-4.8 μm. Conidia spherical to subspherical, smooth to irregular rough, 2.0-3.8 . Sclerotia produced by the same isolate, purple, up 1000 μm in diameter. Colony diameters on Malt Extract Agar 5.0-5.5 cm in 10 days at 25°C, more or less floccose; conidial heads globose or splitting into a few columns, near antimony yellow to ochraceous-buff (R., Plate XV); mycelium white, reverse dull yellow brown to pale auburn (R., Plate II).

　Note： Both A. ochraceus and A. ostianus produce sclerotia of similar size (500-1000 μm) in age. However color of sclerotia are distinct, the former is pink to purple, while the latter is cream buff. A. ochraceus differs from A. sclerotiorum by brown rather than yellow co-nidia.
