There seems to be some uncertainty as to the citation of the second author. Arnold (1884: 316) on transferring Wahlenberg’s Parmelia peliocypha to the genus Acarospora, retained the original spelling of the specific epithet, whereas Fries (1861: 189) had changed the latter into ‘peliscypha’. However, since both recombinations are based on the same type, ‘peliocypha’ and ‘peliscypha’ should be regarded as orthographic variants. Fries’s transfer is of an earlier date than Arnold’s, but instead of the spelling as used by Fries, the original one should be adhered to (Art. 73).
