Myriolecis is a genus of lichen in the family Lecanoraceae. It was originally circumscribed in 1909 by Frederic E. Clements with as the type species. The genus was later reinstated to accommodate the Lecanora disperse group and Arctopeltis. Molecular phylogenetic data showed that this group of species formed a clade that is genetically distinct from Lecanora, and Myriolecis was the oldest name available to hold these species.
