The genus Ramalina Ach. (Ascomycota, Lecanoromycetes, Ramalinaceae) from the Scattered Islands (French Southern and Antarctic Lands), with description of three new species

Résumé

A systematic survey of lichens was performed in 2019 in four of the five territories constituting the French Scattered Islands (Europa, Juan de Nova, Glorioso Islands, and Tromelin), with focus on the genus Ramalina. Species were identified and described using morphological (macroscopic and microscopic) features and 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 are listed from these territories, among which two already described: Ramalina dumeticola and Ramalina ovalis, and three novelties described here: Ramalina gloriosensis, Ramalina hivertiana, and Ramalina marteaui. An identification key to a selection of corticolous similar species (with a solid thallus, shrubby or subpendulous at most, and branches flat to canaliculated) is provided.
