Caloplaca aurantia and Caloplaca flavescens (Teloschistaceae, lichen-forming fungi) in the Czech Republic; with notes to their taxonomy and nomenclature

摘要

A revision of Caloplaca aurantia and C. flavescens in the Czech Republic is provided. Both species are confirmed from the territory; their distribution is reviewed and their ecological demands commented upon. Morphological investigations have confirmed the structure of the cortex and shape and colour of the lobes as the best diagnostic characters of both species; the thickness of the cortex has been found to be another useful character. Nomenclatural confusions regarding both species are discussed and clarified.
