Abstract

The new genus Pseudolepraria Kukwa, Jabłońska, Kosecka & Guzow-Krzemińska is introduced to accommodate Leprariastephaniana Elix, Flakus & Kukwa. Phylogenetic analyses of nucITS, nucLSU, mtSSU and RPB2 markers recovered the new genus in the family Ramalinaceae with strong support. The genus is characterised by its thick, unstratified thallus composed entirely of soredia-like granules, the presence of 4-O-methylleprolomin, salazinic acid, zeorin and unknown terpenoid, and its phylogenetic position. The new combination, P.stephaniana (Elix, Flakus & Kukwa) Kukwa, Jabłońska, Kosecka & Guzow-Krzemińska, is proposed.

Keywords: Lichenized fungi; Neotropics; morphology; secondary metabolites; sterile lichens; taxonomy.
