Image Details

Descripción: Picture taken on the 9th April 2007 at "Gorges du Segre", near Mas paturas, in the vecinity of Bains de Llo, Llo, Oriental Pyrenees, France, Catalonia, epihytal,1.380 m. altitude.

Common but overlooked, because its small size. In Catalonia it has been only mentioned once by Dra. Boqueras at Tarragona, Ports.

Difficult genera for "amateur naturalists". There is an urgent need for the revision and good description of species. I would appreciate confirmation of my determination by any professional lichenologyst with enoUgh background to do it. Determination based on P.L.Nimis criteria in Dryades (P.L. Nimis - Checklist of Italoan Lichens, Trieste University.

Foliose lichen, thallus small, with narrow lobes,from grey to dark brown. Isidia/soralia greenish to brown. Apothecia not seen.

Non chemical spot reactions.

Molt bona

Realment l'esforç que estàs fent en la determinació és molt gran i, com molt bé dius, és fonamental una bona descripció de les espècies per assolir-la.

Molt bon macro. Felicitats.
