The spores (conidia) are brown, 2-celled, and are borne within more or less round fruiting structures (pycnidia). Conidial production occurs (probably holoblastically) on short cells that line the inner walls of the pycnidium. There are a number of similar genera that are distinguished on the basis of pycnidial and spore structure. Most species occur on living or dead plants.
Classification: Botryosphaeriaceae (Botryosphaeriales). Holomorphs: Botryosphaeria, Cucurbitaria, Eutryblidiella, Massarina, and others. Ref: Sutton, 1980; Zambettakis 1954, 1955
