Colony effuse, brown, hairy, with thin white bloom of conidia. Mycelium immersed and also, here and there, thinly aggregated at the surface, composed of subhyaline to brown hyphae 1.2-2.5 µm wide with some cells swollen up to 3.5 µm wide. Conidiophores solitary and scattered, straight or variously bent, subcylindrical, dark brown below, progressively paler toward the apex, with walls thickened (to 1.8 µm) below and thinner above, 95-190 µm long, usually somewhat inflated up to 10 µm and 2- or 3-lobed at the immediate base then cylindrical, 3.7-5.0 µm wide and 9- to 15-septate, the septa being closer together toward the distal end; the Conidiophoee terminates in a phialide. Phialides lageniform, 34-47 µm long, composed of a subcylindrical venter about half the length of a phialide, and a terminal, cylindrical collarette 2.3-3.1 µm wide. Phialoconidia cylindrical with a bluntly rounded apex and a flattened, marginally frilled base, hyaline, 1-celled, (3.5-) 4.5-5.5 (-6.0) x 1.5-2.0 µm, observed in long chains.

HABITAT: on decayed Cyathea medullaris.
