Abstract in another language

Detailed morphological investigations and phylogenetic analyses of the ITS/5.8S nrDNA reveal Umbilicaria caroliniana to be a member of Lasallia. A new combination, Lasallia caroliniana (Tuck.) Davydov, Peršoh & Rambold comb. nov., is proposed. The circumscription of Lasallia is extended by the character state of eight-spored asci. According to the new concept, Lasallia is distinguished from Umbilicaria by comprising species which combine large, multicellular, brown ascospores and a pustulate thallus. The functionally significant differences in ascospore morphology justify the current division of Umbilicariaceae into Lasallia and Umbilicaria, although Umbilicaria remains paraphyletic.
