Cleistothecia on MEA pale yellow to pale brown (2A3), globose, 160-240 μm, sclerotoid with pseudoparenchymature peridium, maturing in 4-6 weeks; asci borne singly, ellipsoidal, subglobose, or globose, 6.1-8.0 × 4.4-5.5 μm, hyaline, containing 8 ascospores; ascospores lenticular with 2 appressed equatorial flanges, wall finely roughened, hyaline, 2.7-3.9 × 2.0-2.2 μm.
Conidiophores and conidia: conidiophores on MEA borne from superficial and aerial mycelium; stipes septate, 170-283 × 1.7-2.8 μm, smooth, thin walled; penicilli mostly biverticillate, less often monoverticillate; metulae in verticils of 2-4, smooth, 11.8-20.7 × 2.8-3.9 μm; phialides in verticils of 4-8, ampulliform, 7.8-10 × 2.8-3.9 μm; collula gradually tapering, with a length 1.1-2.2 μm; conidia subglobose to broadly ellipsoidal, 2.2-3.4 × 1.7-2.5 μm, smooth, thin walled, borne in narrow, entangle columns. |
