Aschersonia cinnabarina P. Henn., Monsunia 1: 37 (1899) Aschersonia napoleonae Pat. & Har., Bull. Soc. Myc. France 20: 65 (1904)

Teleomorph state: Hypocrella discoidea (B. & Br.) Sacc.

Specimens were found on the underside of mostly dicotyledonous or monocotyledonous leaves of forest plants. Hosts are whiteflies (Aleyrodidae). Stromata usually discoid or laterally oval, neck short (stud-shaped), up to 4 mm diam. up to 2 mm high, pale orange to dark orange, base surrounded by small hypothallus; conidiomata ostioles sunken, each in center or circularly arranged, dark orange to red-brown; pycnidia laterally oval up to 500 µm deep, 450 µm diam. broadest part; paraphyses present, linear up to 250 µm long, 1-1.5 µm diam.; conidia fusoid in fresh material (irregular when dry) 10-12.5 x 1.5-2 µm.   This has a wide distribution from Sri Lanka in the Indian Ocean into the eastern Pacific (Philippines). It has recently also been reported from Australia (Queensland). This is one of the most commonly recorded species of insect fungi in Thailand and is found both on the underside of dicotyledonous forest floor plants and saplings as well as members of the Zingiberaceae. The species was dealt with by Petch (1921) and a complete re-description was made by Hywel-Jones & Evans (1993).
