ABSTRACT
A systematic survey of lichens was performed in 2019 in four of the five territories constituting the French Scattered Islands (Europa Island, Juan de Nova, Glorioso Islands, and Tromelin) focusing on the genus Ramalina. Species were characterized using morphological (macroscopic and microscopic) features and an accurate chemical profiling method based on high-performance liquid chromatography coupled with diode-array detection and electrospray ionization tandem mass spectrometry (HPLC-DAD-MS). Five species were found in these territories. Two of them, Ramalina dumeticola and R. ovalis, are already known. Three species are introduced here as new to science: Ramalina gloriosensis sp. nov., R. hivertiana sp. nov., and R. marteaui sp. nov. An identification key is provided for the species found in the area and morphologically closely related taxa.
FUNDING
Species studied in this paper were collected in the frame of the ‘Scattered Island’ inter-agency research consortium (2017–2021) coordinated by the French Southern and Antarctic Lands (TAAF) in partnership with: Centre National de la Recherche Scientifique, Institut de Recherche pour le Développement, Ifremer, Office Français de la Biodiversité, Université de La Réunion & Université de Mayotte. Fieldwork was funded by the inter-agency research consortium and was done jointly by the Conservatoire Botanique National de Mascarin, the Missouri Botanical Garden and the Muséum National d’Histoire Naturelle (UMS 2006 PatriNat OFB – CNRS – MNHN) in the frame of the RECOFFIE (Renforcement des COnnaissances sur la Flore et la Fonge des Iles Éparses) project, implemented as part of the ‘Scattered Island’ inter-agency research consortium (2017–2021). Species chemical profiling was funded by UMR 6226 (Université de Rennes, CNRS, Institut des Sciences Chimiques de Rennes).
