Description

Conidiophores 128-157 μm long (x̄ = 142.5 µm, SD = 14.5, n = 20), 6.5-8.5 μm wide (x̄ = 7.5 µm, SD = 1, n = 20), synnematous, macronematous, septate, unbranched or branched, erect, dark brown at the base, pale brown at fertile, flared apex, sometimes proliferating, 5-8-septate. Conidiogenous cells 37-44 μm long (x̄ = 37.3 µm, SD = 2.1 µm, n = 20), 2.3-4 μm wide (x̄ = 2.5 µm, SD = 1.3 µm, n = 20), monoblastic, terminal, integrated, elongated, pale brown, often separating from the conidium through a break or frill below the base of conidium. Conidia 30-35 μm long (x̄ = 32.5 µm, SD = 2.5 µm, n = 20), 16-19 μm wide (x̄ = 17.5 µm, SD = 1.5 µm, n = 20), 4-septate, ellipsoidal to subglobose, dark brown, pale brown at apical and basal cells, with dark brown to black central cells, with a thick dark band on the central septum; smooth, rounded at apex, truncate at base, sometimes released with part of conidiogenous cell.
