Underside is dark getting paler close to the margins. The high humidity change the apothecia colour to green.
It is one of the first lichens colonizing new surfaces. Generally on tree barks rich in nutrients, specially on planifolia, in very well illuminated places, and moderate humidity. Very common in south Europe. This one was found on the bark of a Holm oak.
