My first contact with the genus Lecania was in observation 96599 and at the time I was not even sure about the genus. This time I went back to the place and, having found again many specimens, I enlarged the places to observe and found in two other (about 200 and 500 meters from the initial) again plenty of specimens. Due to the abundance of material, I made a selection of specimens to present in the attached photos.
To arrive to the species that I propose for classification, first I saw in CNALH those Lecania spp. having a squamulose thallus: two of them, L. brunonis and L. dudleyi have similar features, though the last one is usually epruinose (contrary to the majority of my specimens). However, their distribution is restricted to North America. Nevertheless, in the Notes of the description of the first of those species in CNALH , it is referred that a similar european species is L. spadicea. Then I looked unsucessfully for a description and sucessfully for images. Here are some links: Liquenes de Almeria, dbiodbs, digitalnatura.
The second of these links has several images that in some sense illustrate the variability of the species, fact that I already realized; The last one displays a photo very much similar to many of mines. Therefore, I’m now convinced that Lecania spadicea is the species of the specimens that I observed.
