Observation 101520: Collema callopismum A. Massal.

When: 2012-07-15

Collection location: Lourinhã, Portugal [Click for map]

Who: zaca

No specimen available

Growing on a sandstone platform some 20 meters above the sea (see the photo of the habitat). Some features of these specimens:
- Non fertile;
- Pulvinate thallus, made of pieces of small size, consisting of lobes repeatedly branched;
- Not isidiate, but lobes finally appearing somewhat ‘isidioid’.
According to CNALH it must be Collema callopismum. In europe I only found a norwegian site reporting its existence at maritime localities, which is a point in favor of the classification, due to the habitat. It seems to be a rare species.
