[en] A field trip in Reunion Island in November 2009 led to the collection of about 450 samples of Peltigerales. We realized a checklist of Peltigerales from Reunion comprizing 69 species, including 11 species reported as new for Reunion Island. Among them and related material from Madagascar and Albertine Rift, we identified 27 species of Sticta, with 14 of them representing probably new species. We realized several phylogenetic analyses on 3 genes (ITS, nuLSU, mtSSU) at the family level on Pannariaceae and Lobariaceae and at the genus level on Erioderma, Lobaria, Pseudocyphellaria and Sticta. We discovered two photomorph pairs, the first one composed of the foliose chloromorph and the Dendriscocaulon-like cyanomorph of Lobaria discolor and the second one composed of both foliose cyanomorph and chloromorph of Sticta dichotoma. We also developed 11 primer pairs to amplify microsatellite regions on the Peltigera dolichorhiza group, based on 454 genomic data. A large variation on those microsatellite regions has been shown.
