Anamorph: colonies circular, less frequently irregular, rarely exceeding 1 mm diam., sometimes confluent, appearing zonate with a central region of greyish brown tissue, the periphery medium brown and often with a dark purplish brown raised border. Sporulation hypophyllous, very rarely epiphyllous, sometimes in concentric zones, salmon-pink. Mycelium immersed, composed of branched, septate, hyaline to subhyaline hyphae 2-3 µm diam., forming substomatal, epidermal to subepidermal stromata to 50 µm diam. Conidiophores 23-55 x 4-6 µm, cylindrical, not synnematous, in compact or divergent clusters, straight or flexuous, branched and occasionally 1-septate at the base, smooth, thin-walled, hyaline. Conidiogenous cells terminal, not clearly distinguished from the conidiogenous cells, hyaline, thin-walled, proliferating sympodially, with 1-3 wide flat unthickened scars 2.5-3.5 µm diam. in the upper part. Conidia formed in short dry chains comprised of 2-3 conidia, 25.5-63 x 4-5·5 µm, cylindrical, straight, thin-walled, 0- to 3-septate, hyaline, intercalary conidia truncate at each end, apical conidia truncate at the base, obtuse at the apex, without a gelatinous sheath or appendages.
