The following taxa are synonimized: Heppiaatlantica Gyeln. = H. lutosa (Ach.) Nyl., Solorinaria collemacea(Weddell) Gyeln. = Peltula obscurans (Nyl.) Gyeln., Heppia subrosulataStein. and H. granulata R.G. Werner = P. obscuratula (Nyl.) Egea. Heppiacavalieri R.G. Werner, H. faurelii R.G. Werner and H. nevadensis R.G.Werner are excluded from the genera. From every species, a complete description and other general dates like distribution, habitat and different observations are given.
