Description:Associated with prominent stem cankers on Persoonia; cankers were covered by prominent back conidiomata. Conidiomata pycnidial, globose, 90–180 m diam, dark brown, with central ostiole, 20–30 m diam, exuding a crystalline conidial mass; outer conidiomatal wall covered with brown, verruculose, septate hyphae, 2–2.5 m diam; wall of 3–5 layers of brown textura angularis. Conidiophores lining the inner cavity, hyaline, smooth, branched, 1–4-septate, 10–40  2–2.5 m. Conidiogenous cells terminal and intercalary, hyaline, smooth, subcylindrical, phialidic with prominent periclinal thickening, 5–17  2–2.5 m. A few conidiogenous cells also appear to proliferate percurrently. Conidia hyaline, smooth-walled, guttulate, aseptate, subcylindrical, straight, apex obtuse, base truncate, 1–1.5 m diam, (4.5–)5–6(–7)  (2–)2.5(–3) m. Culture characteristics — Colonies erumpent, spreading, surface folded, with moderate aerial mycelium and smooth, lobate margins, reaching 8 mm diam after 2 wk at 25 C.
