Nomenclatural Notes on Cladonia Species

Abstract

AbstractThe nomenclature and in part also the taxonomy of the following European lichens is discussed: Cladonia cervicornis (Ach.) Flotow subsp. cervicornis and subsp. verticillata (Hoffm.) Ahti comb. nov., C. bacilliformis (Nyl.) Glück, C. portentosa (Dufour) Coem., C. anomaea (Ach.) Ahti & P. James comb. nov. (syn. C. pityrea (Flörke) Fr.), C. conista Robbins ex Allen, C. conoidea Ahti sp. nov. (syn. C. conistea sensu Asah.: contains atranorin and fumarprotocetraric acid, type from England), C. bacillaris Nyl., C. coniocraea auct., and C. ochrochlora Flörke.The African lichen ‘Cladonia gorgonina (Bory) Eschw.’ is typified and its nomenclatural status reconsidered. Under the valid name Cladonia gorgonea Eschw. it is reduced to the synonymy of Cladia aggregata (Swartz) Nyl. The correct name for Cladonia gorgonina auct. is C. glaucopallida Vainio. A list of the new lichen taxa proposed by J. B. Bory, which were invalidly published by Flörke in 1809, is also presented.
