Lichen  (Caloplaca aractina)

Range

In the UK, the range of this lichen is limited to the Lizard Peninsular, Cornwall where it is quite frequent on coastal rocks. There are other records from the British Isles but these are now believed to be incorrect. It is also found along the coasts of western Europe and from inland southern Europe.

You can view distribution information for this species at the National Biodiversity Network Gateway.

Habitat

This lichen likes sloping rocks, up to 100 metres above high water mark. On the Lizard Peninsular, it is always on serpentine rock. Elsewhere, it seems to prefer silica-rich rocks.
