The visible colonies are widely effused or compact and velutinous, brown¬ish, composed of mostly branched phialophores bearing hyaline to pale straw-coloured globules of phialospores.
The mycelium is immersed and composed of pale brown to dark brown, septate, branched hyphae 2.0-5.4 µm wide. The phialophores are simple or branched, arise singly or in groups of up to 5 from swollen cells of the repent hyphae, and are crowded or form a thin turf 155-550(-750) µm high. The main stalk is straight or bent, brown to dark brown, paler toward the distal end, septate, markedly thick-walled towards the base and thinner-walled above, 5.0-6.5 µm wide just above the basal cell which is up to 14 µm wide, tapering gradually to 1.6-2.4 µm toward the subacute apex. The main stalk bears 1 to 3, straight or flexuous, unilateral or alternate branches arising almost at right angles to the main stalk then curving upward. Secondary and tertiary branches may also develop. The distal sterile ends of the main stalk and branches have the walls ornamented with numerous disc-like excrescences up to 1.6 µm wide and 0.4 µm high.
The phialides, which occur in whorls of 3 to 7, arise just below the distal septa of a series of (1-)2-3(-4) cells of the phialophore; such fertile zones develop toward the bases of the main stalk and its branches. The cells of the phialophores vary considerably in length, those bearing the phialides being as short as 5-0 µm, the others being progressively longer towards the base and apex of the main stalk or its branches. The phialides are sessile, straight, narrowly ovoid to ovoid, generally tightly adpressed to the main stalk or branches that bear them, pale brown to subhyaline, 9.4-13.5(-17.5) µm long, 3.5-4 µm wide below, and 1.0-1.6 µm wide at the tapered, open distal end, which lacks a well defined collarette.
The phialospores are hyaline, strongly or gently curved, falcate, 18-35 µm long, 1.6-2.6 µm wide non-setulate, non-septate, produced in slime and finally enveloping the phialides as a hyaline or pale straw-coloured mass.
