Rediscovery of Five Rinodina Species Originally Described from Southwest China and One New Species

Rinodina is a lichenized fungal genus belonging to the Physciaceae, with c. 300 species worldwide. Nearly century ago, Zahlbruckner described five of from Southwest China. The type collections were only records for these species. In present study, new four species: cornutula, R. globulans, handelii, and setschwana, recently species, pluriloculata, are documented based on specimens collected holotype localities. Furthermore, one was discovered: hengduanensis, characterized by areolate subsquamulose thallus, jigsaw-like areoles, lecanorine apothecium, Dirinaria-type ascospores. setschwana transferred Buellia its morphology, chemistry, phylogeny proposed as setschwana. We provide detailed morphological descriptions, pictures, molecular phylogenetic analyses.
