Colony inconspicuous, pale brown. Phialophores solitary or aggregated, straight or variously bent, up to 42 µ long and 4 µ wide at the base, composed of a cylindrical stalk which is pale brown, smooth-walled, indistinctly 1-4-septate; with a terminal phialide. Phialides lageniform, 17-26 [22] µ long; venter ellipsoidal, 9-16 [ 12.5] x 3-4 [3.7] µ; collarette cylindrical, basally fuliginous, 7-11 [8.3] x 1.5-2 µ; transition from venter to collarette abrupt and marked by a constriction in the wall; ratio of mean lengths of collarette and venter = 0.65:1. Phialoconidia catenulate, narrowly clavate to cylindrical; base truncate, apex rounded, slightly wider; unicellular, hyaline, smooth-walled; 3.5-8 [6.2] x 1-2 [1.5] µ; mean conidium length/ width ratio = 4:1.
