Abstract
A two-locus phylogenetic hypothesis of the family Roccellaceae is presented based on data from the nuclear ribosomal large subunit (nucLSU) and the second largest subunit of RNA polymerase II (RPB2). This analysis includes 341 sequences (166 newly generated) and 180 specimens representing about 114 species. The genera Lecanactis, Roccellina, Schismatomma and Sigridea were found to be paraphyletic/polyphyletic. In order to make these groups monophyletic, the new genera Crocellina, Diromma, Gyrographa, Gyronactis, Ocellomma, Pseudoschismatomma, Psoronactis and Vigneronia are described. The genus Sagenidium is placed in synonymy with Lecanactis. The new species Enterographa incognita, Gyronactis asiatica and Lecanactis submollis are described. Several species of Opegrapha are transferred to the Roccellaceae. Sorediate morphs are recorded for the first time in the genus Syncesia.
