The taxonomy of the lichen Fuscidea cyathoides (Fuscideaceae, Umbilicariomycetidae, Ascomycota) in Europe

Abstract

Based on morphometric and molecular methods, the taxonomy of the infraspecific taxa of Fuscidea cyathoides (Ach.) V. Wirth & Vězda, var. corticola (Fr.) Kalb and var. sorediata (H. Magn.) Poelt, has been assessed. No formal taxonomic recognition should be attributed to the morphological and ecological variation. Accordingly, var. corticola and var. sorediata are synonymized with F. cyathoides var. cyathoides. New synonyms at the specific level are Fuscidea fagicola (Zschacke) Hafellner & Türk and F. stiriaca (A. Massal.) Hafellner.
