Stromata black, formed within the host tissue, later erumpent, usually small and scattered, in C. fructicola confluent to form an effuse crust, bearing perithecia and in some species also pycnidia, perithecia seated on t.he stroma, cespitose, elongated (flaskshaped, barrel-shaped, top-shaped, clavate, etc.) the apex rounded and undifferentiated, or definitely lobed, in C. fructicola flattened into a disc as in Tripospora; not provided with a typical ostiolum, at maturity dehiscent either by a wide opening resulting from one or more deep clefts, or as in C. fructicola, fimbriate-lacerate at the apex and finally dehiscent by a wide funnel-shaped opening; asci ovate to clavate, long-stalked, thin-walled, evanescent, usually 8-spored (varying from i-8), aparaphysate; ascospores when young hyaline, smooth and by mutual pressure polyhedral; at maturity, spherical, brown, thick-walled, echinulate, unicellular; pycnidia seated on the stroma among the perithecia, more or less globose, black; pycnospores hyaline, elongated to fusiform, unicellular.
