The genera Heppia and Peltula inWestern Europe and Northern Africa are studied. Six species belonging to Heppia and ten species and one variety to Peltula are described. Heppiagigantea Egea & Llimona is described here as new. Three new combinations are proposed: Peltula crispatula (Nyl.) Egea, P. obscuratula (Nyl.) Poelt ex Egea & P. psammophila (Nyl.) Egea. The following taxa are synonimized: Heppia atlantica Gyeln. = H. lutosa (Ach.) Nyl.,Solorinaria collemacea (Weddell) Gyeln. = Peltula obscurans (Nyl.)Gyeln., Heppia subrosulata Stein. and H. granulata R.G. Werner = P.obscuratula (Nyl.) Egea. Heppia cavalieri R.G. Werner, H. faurelii R.G.Werner and H. nevadensis R.G. Werner are excluded from the genera. Frome very species, a complete description and other general dates like distribution, habitat and different observations are given. For every taxon a distribution map is added. By the last, an identification key including all treated species is presented here.
