The new species is characterized by a lack of setae surrounding the apothecia and by fusiform, aseptate ascospores containing multiple guttules. Rhexocercosporidium camporesii has larger asci and ascospores than other species of Rhexocercosporidium. Phylogenetic analyses using a combined gene analysis of LSU and ITS sequence data indicated that the new species belongs to Ploettnerulaceae (Helotiales).
