Sclerotial strains produce bright yellow, floccose mycelia. Sclerotial strains produce small numbers of large, fused sclerotial bodies in discrete pockets hidden within the mycelium.
-
Aspergillus alliaceus. No branching was observed in A. alliaceus conidiophores. Sclerotial strains typically produce large numbers of exposed, uniformly-shaped sclerotia across the mycelial surface.
