Colonies epiphyllous or hypophyllous of leaves appearing as blackened areas. Surface mycelia absent. Sexual morph: Ascostromata amphigenous, irregularly and loosely scat- tered, aggregated or confluent, blackened, carbonaceous to membraneous, dark reddish-brown at the margin. Hamathecium composed of numerous, filiform, hyaline or pale greyish-yellow pseudoparaphyses with rounded ends embedded in a gelatinous matrix. Asci bitunicate, fissitunicate, 8-spored, hyaline, cylindrical to cylindrical clavate, short pedicellate, thick-walled. Ascospore 2–3-seriate, ellipsoidal, hyaline, initially guttulate, 2-septate, center cell larger than end cells, obtuse at both ends, smooth-walled. Asexual morph: Conidiomata superficial, multiloculate, dark brown to black, slightly carbonaceous. Conidiophores usually reduced to conidiogenous cells. Conidiogenous cells percurrently proliferating, ampulliform, subcylindrical to cylindrical, discrete, hyaline to pale brown, smooth. Conidia variously shaped, globose to subglobose, pale brown to dark brown, smooth-walled, with basal appendage, cellular, cylindrical to subcylindrical, hyaline, flexuous, thin-walled.
Notes: Spegazzini (1921a, b) introduced Campoa with the type species of Campoa pulcherrima. and later Campoa pulcherrima was synonymized as C. granulosa by Arx (1958). Species of Campoa is characterized by superficial, flat, black ascostromata with filiform pseudoparaphyses, cylindrical to cylindrical clavate asci and ellipsoidal ascospores (Inácio and Cannon 2008).
Type species: Campoa pulcherrima Speg., Boln Acad. nac. Cienc. Córdoba 25: 90 [no. 173, repr. 92] (1921)
Other accepted species: species Fungorum – search Campoa.
