Image Details

Descripción: Picture taken on the 10th March 2007 near Corredor Sanctuary, Llinars del Vallés, Barcelona, on Quercus suber bark.

It is a very rare lichen. It has only been mentioned by Dr. Gomez Bolea from Alt Camp and Montseny area and by Drs. Barreno & Fos at Ribatejo , Portugal. I have found it with Parmelia hypoleucina as in Portugal, according to S. Fos these.
It seems a temperate lichen folowing Clauzade-Ozenda.

Corticolous, small lichen, erect (4-6 cms), cylindrical filamentous thallus, very divergent basal branches, dense, grey-green, growing in tuft, almost no fibrils, scarce small papillae, granulous soralia.
It is easy to distinguish by the red spots on the thallus.

Med. K+ yellow, red after, P+

stictic, menegaziacic and lobaric acids

Very rare or not well-known

Preciosa

Composició impactant i curulla de tonalitats de colors. Felicitats per la captura.

Molt interessant l'explicació i excitant el fet de trobar especímens molt rars i no citats, anteriorment, en zones determinades.
