Conidiophores arising sometimes singly but usually in dense fascicles from the upper cells of the stromata, simple, straight or flexuous, subulate, smooth-walled, brown to very dark brown, septate, 250-950 µm long, 14-26 µm thick at the base, tapering to 8.5-12 µm near the apex, with well-defined, small pores up to 12 whorls at the apex and laterally beneath the upper 1-12 septa. Conidia straight or flexuous, obclavate, smooth-walled, subhyaline to rather pale golden brown, sometimes darker, 6-16 pseudoseptate, 48-118 (68) µm long, 11-20 (15) µm thick in the broadest part, tapering gradually to 5-7 µm near the apex, with a large blackish-brown to black scar at the base.
