Conidiophores: Conidiophores arising from the aerial mycelium of developed pustules, asymmetrically branched, the branches producing phialides directly or rebranching, the secondary branches producing phialides along the length and ending in a single phialide; sometimes the main axis of a conidiophore is terminating in a sterile, septate, branched or unbranched, hypha-like elongation. Phialides: Phialides mainly arising singly, less frequently in appressed to divergent whorls of 2–3, typically curved, ampulliform to broadly lageniform, sometimes hooked or sinuous. Conidia: Conidia green, smooth walled but with conspicuous sinuate, bullate or wing like inflations of the outer wall, ellipsoidal, 4.5–7.5 × 3.5–4.5 µm.

White mycelium producing yellow pustules turning to dark green color with the age. The pustules uniformly spread throughout the plate leaving a concentric green ring at the center. The reverse of the plate is colorless. Conidiophores: The main axis terminates in a septate elongation with a single phialide at its tip and fertile branches arising near the base. Conidiophore branches arising at angles of 90° or less concerning the main axis, paired or not, rebranching sparingly to produce phialides directly or at the tips of short secondary branches.

Mycelium is mostly submerged, less aerial mycelium which is floccose and white. Compact cushioned pustules looking velvety due to the presence of numerous, flexuous sterile conidiophore apices. These pustules are white at first, becoming yellow, then pea-green followed by olive green. Colorless at the reverse of the Petri plate. Conidiophores: Conidiophores in pustules are broad, comprising a regular, undulate and humate sterile elongation with the phialides arising near the base. The lateral branches typically comprise one or a few, broad cells with phialides arising at the tip and along the length. The internodes between branches are short and the phialides densely clustered. Phialides: Phialides are short, broadly ellipsoidal to ovoidal, pyriform and ampulliform, formed on small branches, smooth - walled, hyaline or pale green color. Conidia: Oblong to ellipsoidal and smooth, 5.0–6.0 × 3.0–4.0 µm, green. Chlamydospores: Chlamydospores terminal and intercalary, globose, 4.0–8.0 µm diam.
