Description

On PDA, growth is not particularly rapid. usually white powdery mycelium. The under-surface is often white, but can vary in several colours (yellow, pink and purple are most common). Very little aerial mycelium, although isolates vary. Globose microconidia in abundance are formed in the powdery mycelium.

On malt agar, the mycelium is short, white to yellow or pale orange. Sporodochia are rare.

Conidiophores: Unbranched and branched monophialides and polyphialides.

Macroconidia are absent. Microconidia are abundant, globose shaped, in clumps.

Chlamydospores are absent.

Top plate has a naturally infected wheat seed with typical sparse or powdery mycelium growth, whitish pink with a darker pink/purple center. Bottom plate shows the control culture. Only microconidia are produced, and typically in clumps. Macroconidia and chlamydospores are absent.
