Placolecis
Placolecis is a genus of lichen-forming fungi in the family Catillariaceae. 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. He did not assign a type species for the genus. Josef Hafellner designated a lectotype for Placolecis balanina in 1984, but subsequently, this taxon was folded into P. opaca. Species
Placolecis kunmingensis  – China
Placolecis loekoesiana 
Placolecis opaca 
Placolecis sublaevis  – China

The taxon once known as Placolecis plumbea  is now considered synonymous with Pectenia plumbea. References
