Placolecis

Placolecis is a genus of lichen-forming fungi in the family Catillariaceae.^[2] It has four species of saxicolous (rock-dwelling) and crustose lichens. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1857.^[3] He did not assign a type species for the genus. Josef Hafellner designated a lectotype for Placolecis balanina in 1984,^[4] but subsequently, this taxon was folded into P. opaca.^[5]
