Colony effuse, brown to dark brown, hairy. Superficial hyphae thinly aggregated, pale brown, smooth. Phialophores solitary or in lax clusters, erect or variously bent; 115-168 µ long, 5-6 µ wide at the base; basal cell slightly inflated, subglobose and up to 7.5 µ diam.; multiseptate, brown or dark brown below, becoming lighter above; with a terminal phialide. Phialides lageniform, 48-58 [53] µ long, pale brown; venter subcylindrical, 20-27 [23.6] x 6-8.5 [7.4] µ; collarette cylindrical, 26-33 [29] x 3.5-4 µ; transition from venter to collarette abrupt; ratio of mean lengths of collarette/venter = 1.2:1. Phialoconidia extruded singly or in short chains; cylindrical, apex rounded, base truncate with a minute marginal frill; unicellular, hyaline, smooth; 13-17 (-18) [15] x 2.5-3 [2.7] µ; mean conidium length/ width ratio = 5.5:1.

Known distribution: New Zealand.

Habitat: On dead leaves of Nothofagus solandri var. cliffortioides.
