Saprbic on dead stems of Chromonaela odorata (L.) RM King & H. Rob (Asteraceae). Sexual morph Undetermined. Asexual morph Conidiomata (–280)300–350 × 370–450(500–) µm (x̄= 300.1 × 415.4 µm, n=5), solitary, immersed to semi–immersed with 2–3 locules, globose to subglobose, black. Ostiole absent. Peridium 45–50 (60–) µm wide, multi–layered, comprised of dark brown cells of Textura angularis. Hamanthecium 3–5 µm wide, numerous, hyaline, aseptate, paraphyses. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 1–2 µm wide, holoblastic, cylindrical, hyaline. Conidia 15–20 × 5–10 µm (x̄= 17.23 × 6.9 µm, n=15), aseptate, rough–walled, granular appearance, hyaline to dark brown, ellipsoidal, without appendages.
Culture characteristics: Conidia germinating on PDA within 24 hr, reaching 85 mm after 7 days at room temperature, concentric, flat, irregular, rough surface, greenish–grey.
