Abstract

Abstract: Detailed morphological investigations and phylogenetic analyses of the ITS/5.8S nrDNA, mtLSU and RPB 2 of the Umbilicaria crustulosa–U. spodochroa species complex reveal Umbilicaria hirsuta var. meizospora Harm. to be a separate species. The lectotype has been designated in ANGUC and a new combination Umbilicaria meizospora (Harm.) D. M. Masson & Davydov is proposed. Umbilicaria crustulosa var. badiofusca was recognized as the heterotypic synonym of U. meizospora and the lectotype was designated based on Frey's collection preserved in G. We provide a full description of U. meizospora and outline its distribution and ecology. The species is newly reported from Austria.
