Descripción: |
Picture taken on the 24th February 2007, "Mirador" close to Can Penyacans, vertical surface, enriched, close the road, 1.200 m. altitude, Montseny, Barcelona.
This lichen is not included in the Base DBC. It was already mentioned by Dr. Nestor Hladún (Aportació a la Flora, morfologia i vegetació dels líquens de la part alta del Montseny, pag.128) and it has been found in the same place. It is relatively common.
Saxícolous, foliose lichen, forming rosettes, but not always, lobes flat or a little convex, with branches, upper part grey colour, with pseudocyphella, dots white-ochre, sorediated, soralia at the tips of the lobes, lip-shaped, with the age often globose, laminal too, lower side black, rizhinae. No apothecia.
Cortex K+, Cl-
Medulla K+
Look at Flechtenbilder images by Ulrich Kirschbaum.
I suggest reading the following work related to Physcia:
Atienza,V & E. Barreno (1989). Estudio morfológico al M.E.B. y comportamiento ecológico de algunos táxones epifíticos del género Physcia. Anal. Jard. Bot. Madrid 46 (1):283-294.
A very professional paper and that it is possible to obtain through internet.
