Range & Status
This species prefers near-vertical, ultramafic serpentine rocks in sunny, south-facing
positions near the coast. Here it often grows in close association with another rare lichen Collema latzelii . A Mediterranean species, described as new to the British lichen flora from the Lizard Peninsula which remains its only British site. All the known sites lie within a NNR or SSSI. Recent survey work has revealed numerous populations in the Kynance Cove area, some of which are prone to heathland fires.
