Colonies floccose to powdery.initially white,becoming roseate to purple. Two type of microconidia were observed:lemon-shaped, pyriform to globose O-1septate,6. 5 -10. 0×4. 5-7. 8 μm. and elliptical to allantoid .mostly O-septate,4 -12 × 1. 5-3. 1 μm. Microconidia formed in chains and false heads. Conidiogenous cells were polyphialides and simple phialides. Macroconidia falcate,3-4(5)septate,28-64× 2. 6 - 3. 5 μm.
