Cytospora Ehrenb.

Index Fungorum number: IF 7904; MycoBank number: MB 7904

Cytospora was introduced by Ehrenberg (1818) and typified by C. chrysosperma (Pers.) Fr. Most Cytospora species are important plant pathogens (Adams et al. 2005; Fan et al. 2020). Cytospora-canker is a destructive disease of numerous hosts and causes serious economic losses. Leucostoma, Valsa, Valsella, and Valseutypella have been treated as the synonyms of Cytospora (Rossman et al. 2015; Senanayake et al. 2017; 2018). Identification of Cytospora species is difficult due to insufficient phylogenetic understanding and overlapping morphological characteristics (Pan et al. 2020). Currently, there are 340 accepted species in Cytospora (Species Fungorum 2023).
