Observation 161308: Rhizocarpon Ramond ex DC.
When: 2014-03-02
Who: zaca
No herbarium specimen

Notes: This was perhaps the most intriguing of the lichens I observed this time. It has the shape including a proeminent prothallus and lived among Rhizocarpon spp. in a boulder. However, the thallus itself consists of very small green squamules with whitish margins. So, is it a Rhizocarpon? I have no alternative for the classification.

I have observed before (obsevation 78970) something that I believed (and still do) to be R. bolanderi); This one looks a bit different, namely the colour of squamules, but this could be a consequence of the rainfall. I think that this is no longer a mistery and, probably, it is R. bolanderi again. Thanks, Jason, for the help.

There is something resembling this in N. Amer.

Consider Rhizocarpon bolanderi. It has the overall habit of a Lecidea atrobrunnea group species, but the spores are clearly brown and muriform. There must be related species in southwest Europe.
