Notes: These specimens were found close to the sea in an upper platform (see the photo of the habitat). They were spread through the soil in little pieces, each one resembling a short hand. I didn’t find nothing similar in the CNALH for the genus Collema, but after some searching found an european species with these characteristics, Collema fragile, that in some circunstances can have a pulvinate thallus like this (see Irish lichens and Wales-lichens). According to these references, C. fragile has “lobe ends splayed, tips of young lobes finely pubescent”. I made some attempts to verify this feature, but it is very difficult to separate inate pruina from natural dust (see the photos attached).
