Anamorph: conidiomata absent. Conidiophores in clusters of 6-20, formed on a compact dark brown to black, superficial basal stroma to 80 µm diam. and one cell thick. Conidiophores 120-170 x 4-6 µm, dark brown at the base and becoming wider (to ca 10 µm) and much paler immediately below the conidium; sometimes proliferating irregularly by extension through a lower, funnel-shaped structure housing the old fertile locus. Conidia monoblastic, not formed in chains, 35-42 x 17-19 µm, ellipsoidal, usually 5-septate, the cells at each end pale brown and the central cells brown to black-brown and often opaque, sometimes with broad black bands at the middle septa, without a gelatinous sheath or appendages.
