Abstract

The study includes the following accepted species: Cladortia ciliata Stirt., C. portentosa (Duf.) Zahlbr., C. uncialis (L.) Wigg., C. metacorallifera Asah., C. sulpharina (Michx.) Fr., C. polydactyla (Flörke) Spreng., C. rangiformis Hoffm., C. crispata (Ach.) Flot., C. squamosa (Scop.) Hoffm., C. stricta (Nyl.) Nyl., C. ecmocyna Leight., C. maxima (Asah.) Ahti, C. gracilis (L.) Willd., C. macroceras (Flörke) Ahti, and C. firma (Nyl.) Nyl. New taxa are Cladortia portentosa subsp. pacifica f. decolorans Ahti and Cladonia stricta var. uliginosa Ahti. New combinations are Cladonia portentosa f. subimpexa (Duvign.) Ahti, Cladonia portentosa subsp. pacifica (Ahti) Ahti Cladonia rangiformis var. gracillima (Mont.) Ahti, Cladonia maxima (Asah.) Ahti, and Cladonia macroceras (Flörke) Ahti. The epithets reduced to synonymy include: Cladonia leucophaea des Abb. ( = C. ciliata var. ciliata), C. tenuis (Flörke) Harm. ( = C. ciliata var. tenuis), C. impexa Harm. ( = C. portentosa), C. gonecha (Ach.) Asah. ( = C. sulphurina), C. flabelliformis Vain. ( = C. polydactyla), C. uncialis subsp. dicraea (Ach.) D. Hawksw. ( = C. uncialis subsp. biuncialis), C. crispata var. subcrispata Hennipm. (nom. illeg., but no correct name proposed), C. squamosa var. allosquamosa Hennipm. ( = C. squamosa var. subsquamosa), C. cerasphora Vain. ( = C. stricta var. stricta), C. lepidota (Ach.) Nyl. ( = a nomenclatural synonym of C. phyllophora, but generally applied for C. stricta coll.), C. gracilescens (Flörke) Vain. ( = a nomenclatural synonym of C. phyllophora, but generally applied for C. stricta var. uliginosa), C. nylanderi P. Cout. [ = C.firma (Nyl.) Nyl.], C. firma (Laur.) Kremp. (nom. illeg., but no correct name proposed). C. maxima and C. metacorallifera var. reagens Asah. are reported, as new to Europe, while C. elongata (Jacq.) Hoffm. is excluded from the European flora. New reports on chemistry: C. portentosa subsp. pacifica f, decolorans (perlatolic acid constant, ursolic acid as accessory; no usnic acid), C. stricta var. uliginosa (fumarprotocetraric acid, atranorin), C. maxima (fumarprotocetraric acid constant, atranorin accessory) and C. macroceras (fumarprotocetraric acid).
