Observation 276198: Collema parvum Degel.

When: 2017-05-07

Collection location: Planalto das Cezaredas, Portugal [Click for map]

Who: zaca

No specimen available

Growing on calcareous rock.
There is a group of similar species with very small thalli: C. dichotomum, C. fragile, C. multipartitum, C. parvum. The first and the third lack isidia, thus being ruled out. On the other hand, the second has hialine hairs on the upper surface of the thallus, which does not seems to be the case. Hence, only C. parvum remains.
