Li et al. (2016) introduced this monotypic genus to accommodate coelomycetous taxon, Camporesia sambuci based on the analysis of LSU, ITS, rpb2, and tub2 markers. Camporesia is characterized by globose, superficial to subepidermal, separate, unilocular, ostiolate, and thick-walled pycnidia. The pycnidial wall is composed of cells of the texura angularis, with inner hyaline layers gradually merging with outer dark brown layers. Conidiophores are short, unbranched, hyaline, and emerge from the innermost layer of the wall cells. Conidiogenous cells are hyaline, phialidic, ampuliform, and smooth-walled, with periclinal wall thickening at the tip. Camporesia species have pale brown fusiform conidia that are rounded at both ends, 2–3-septate and smooth-walled (Li et al. 2016). However, the sexual morph remains undetermined. Camporesia sambuci is saprobic on dead plant stems (Li et al. 2016). The genus is distinct from libertella-like species in that it contains pale brown fusiform conidia (Li et al. 2016).
