Description

From ISTA's Common Laboratory Seed Health Testing Methods for Detecting Fungi:

The growth of the fungus on seed is characterized by immature, white heads and mature heads in shades ranging from yellowish cream to green. Conidiophores bearing the heads are clearly seen when the growth is light. They are long and hyaline terminating in bulbous heads. 

Conidia globose to subglobose, usually rough (echinulate) yellowish-green, 3-5μm.
