Abstract

The morphology and chemistry of the type specimens for the four species of brown Parmelia described by A. N. Oxner have been studied. The correct name for the widely distributed Northern Hemisphere taxon, now generally known as Melanelia substygia (Räsänen) Essl. (Parmelia substygia Räsänen), is now M. tominii (Oxner) Essl. Parmelia borisorum Oxner and Parmelia altaica Oxner are also synonyms of M. tominii. Parmelia teretiuscula Oxner is a synonym of Melanelia stygia (L.) Essl.
