Caloplaca aractina

Range & Status

A very rare species of coastal siliceous rocks currently known only from the Lizard Peninsula. Old specimens from the Isle of Man, Cumberland and Westerness have been recently re-examined and found not to be this species. During a recent Plantlife survey (2000) C. aractina was found in abundance on serpentine in the Kynance cove area. This species also proved to be unexpectedly frequent on serpentine along the eastern coast of the Peninsula, with at least eight scattered sites from Enys Head to Coverack. None of the populations appear to be threatened.
