Rossman et al. (2015) synonymized Pseudovalsa under Coryneum. The asexual morph is the most common morph seen. There are more than 70 species recorded under Coryneum. However, molecular sequence data are lacking for most species. Wijayawardene et al. (2016b), Senanayake et al. (2017a), Jiang et al. (2018) and Senwanna et al. (2018) introduced several species providing phylogenetic analyses. Common host genera include Acer, Betula, Castanea, Eucalyptus, Populus, Quercus, Rosa, Rhododendron, Salix, Sorbus, Sambucus, Tilia, and Vitis (Farr & Rossman 2018). Coryneum species are common in temperate regions than in tropical regions. Coryneum brachyurum, current name Coryneum lanciforme (Species Fungorum 2020) is illustrated in this entry.

Type species: Coryneum umbonatum Nees.

Other accepted species: Species Fungorum – search Coryneum.
