Psilolechiaceae, a new family in Lecanoromycetes of lichenized fungi, is introduced to accommodate all species of Psilolechia with the type species Psilolechia lucida by Miadlikowska et al. (2014), based on phylogenetic analyses. Psilolechiaceae is a monogeneric family classified in the order Lecanorales, comprising crustose lichens with effuse, ecorticate, and leprose thalli, and the species of Psilolechiaceae prefer shaded, humid places. The family Psilolechiaceae is characterized by immarginate apothecia, 8-spored, cylindrical-clavate, elongate K/I+ dark blue tube-like structure, non-amyloid ascus wall, K/I+dark blue outer layer asci, oblong-ovoid to dacryoid, and hyaline ascospores (Miadlikowska et al. 2014).

Type genus: Psilolechia A. Massal.

Other accepted species: Species Fungorum – search Psilolechiaceae
