Byssoloma is large, mostly tropical genus of the Pilocarpaceae with c. 50 species, several of which are foliicolous (Santesson 1952, Lücking 2008). European and Macaronesian species were treated by Sérusiaux (1993, 1998), Sérusiaux & al. (2002), Breuss (2016a,b), and Cannon & al. (2022). All of the Italian species are very rare and often threatened, most of them occurring in small warm-humid areas hosting several subtropical lichens with a relict character.
