This is a key to all species of Pyrenula and Eopyrenula known to occur in Italy, for a total of 9 species (Nimis 2016). Pyrenula is a large, mainly tropical genus of the Pyrenulaceae, which is poorly represented in Europe. A worldwide key was published by Aptroot (2012), who accepted 169 species out of the c. 745 named taxa in the genus. Good descriptions and a key to all British species are in Orange (2013). The genus Eopyrenula, with c. 6 species wordlwide, was segregated from Pyrenula owing to the different ascospores and macroconidia, the lack of an involucrellum, and the very small perithecia; a single species occurs in Italy.
