| Popis: | The species Immersaria cupreoatra has repeatedly been reassigned between Bellemerea and Immersaria. This caused us to reconsider the relationships between Bellemerea and the lecanorine species of Immersaria, and to question the monophyly of Immersaria. Among 25 genera of the family Lecideaceae, most have lecideine apothecia, with the exception of Bellemerea and Koerberiella, which have lecanorine apothecia. According to previous classifications, Immersaria included species with both lecanorine and lecideine apothecia. A five-loci phylogenetic tree (nrITS, nrLSU, RPB1, RPB2 and mtSSU) for Lecideaceae showed that Immersaria was split into two clades: firstly all the lecideine apothecia species, and secondly all the lecanorine apothecia species. The latter were closely related to the remaining lecanorine apothecia genera: Bellemerea and Koerberiella. Therefore, the genus concept of Immersaria was revised accordingly, and a new lecanorine genus Lecaimmeria was proposed. Furthermore, five new species for Immersaria, and seven new species and three new combinations for the new genus Lecaimmeria were proposed. Keys to Immersaria, the new genus Lecaimmeria and allied genera were provided. |
