Hypotrachyna penduliloba and Remototrachyna pandani, two new species in the hyperdiverse lichen family Parmeliaceae from Réunion in the Mascarene Archipelago

Abstract

Extensive exploration of lichen diversity in the tiny and remote tropical island of Réunion (Mascarene Archipelago, Indian Ocean) yielded two new species in the hyperdiverse lichen family Parmeliaceae. Morphological, anatomical and chemical characters and molecular inferences from 3 loci (ITS, nuLSU and mtSSU) strongly support their assignment t o H y p o t r a c h y n a ( s u b g e n u s L o n g i l o b a e ) and Remototrachyna. Hypotrachyna producta is further assigned to H. subgenus Longilobae and is newly reported for Réunion as well as Remototrachyna costaricensis.

Three new species of Krogia (Ramalinaceae, lichenised Ascomycota) from the Paleotropics

“…Aptroot et al 2018; Lücking et al 2014; Masson et al 2015; Naksuwankul et al 2016; Sodamuk et al 2017). It seems that the full diversity of tropical lichens is yet to be discovered.…”

The genera Hypotrachyna and Remototrachyna (Parmeliaceae, Ascomycota) in northeastern Argentina

“…Chemistry: Upper cortex K+ yellow, UV-(atranorin, major/minor); medulla K-, C-, KC-, UV-(non-identified fatty acids, all minor). Distribution: America, Africa, Asia, Europe, and Oceania (Sipman et al, 2009;Masson et al, 2015). In South America: Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela (Eliasaro et al, 1998;Sipman et al, 2009), and Argentina.…”
