Abstract

The nomenclature, chemistry, taxonomy, distribution and ecology of Aspicilia tuberculosa (Ach.) Laundon comb, nov., Buellia ocellata (Flotow) Körber, Pycnothelia papillaria Dufour, Rhizocarpon richardii (Lamy ex Nyl.) Zahlbr. and Rinodina aspersa (Borrer) Laundon comb. nov. are discussed. Aspicilia tuberculosa, related to A. caesiocinerea, has apparently not been collected since c. 1830 and may now be extinct. The name Buellia verruculosa has been wrongly applied and the species should be called B. ocellata. The name Pycnothelia papillaria is retained, but with a modified author citation. Rhizocarpon constrictum is a synonym of R. richardii. Rinodina fatiscens is shown to be a synonym of R. aspersa. The nomenclature of Aspicilia caesiocinerea and Rinodina atrocinerea is also considered, the latter requiring change of author citation.
