Classification: Boliniaceae, Boliniales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood. Sexual morph: Ascostromata erect, immersed to semi-immersed, erumpent through bark of host, carbonaceous, black, glabrous, pulvinate, peltate, discoid or valsoid, hemispherical or spherical, sometimes with broad attachment to the substrate. Ascomata perithecial, gregarious, carbonaceous, cylindrical, black, ostiolate, with necks, periphysate. Asci 8-spored, unitunicate, cylindrical, apex rounded, pedicellate, with J- apical ring. Ascospores uniseriate, cylindrical to ellipsoidal, aseptate, pale brown or dark brown, smooth-walled, with guttules. Asexual morph: Undetermined (adapted from Vasilyeva 1997; Vasilyeva et al. 2007).

Notes: Vasilyeva (1997) transferred Camarops pugillus (≡ Sphaeria pugillus Schw.) to Camaropella as generic type. Camaropella species do not have a lopadostomoid type of stromata as found in Camarops, but has special eutypoid and eutypelloid or valsoid forms (Vasilyeva 1997). She also introduced a second species, Camaropella lutea (Vasilyeva et al. 2007). These two species are nested in Boliniales and distant from Camarops tubulina based on phylogenetic analysis (Huhndorf and Miller 2008; Untereiner et al. 2013; Vu et al. 2019). In this study, strains of Camarops amorpha, C. microspora and C. plana, which have pulvinate or peltate stromata (Miller and Huhndorf 2005; Spatafora et al. 2006; Raja et al. 2011), clustered with Camaropella species with 89%ML/0.93PP support, and this clade is distant from Camarops clade (Untereiner et al. 2013; this study). Therefore, we recommend transferring these three Camarops species to Camaropella. However, Camaropella and Camarops are very similar in morphology, in the cylindrical asci, ellipsoidal ascospores and the arrangement type of the ascomata in stroma. The relationship between Camarops and Camaropella needs to be resolved with more collections and sequence data.

Type species: Camaropella pugillus (Schwein.) Lar.N. Vassiljeva, Mikol. Fitopatol. 31(1): 6 (1997).

Other accepted species: Species Fungorum – search Camaropella.
