Ciliate strap-lichen Heterodermia leucomela

Best Time to See
Habitat Coastal

A white, branching lichen.

Distinctive long black hairs round the edge of each strap like frond.


It used to be distributed in several counties in southern England but is now restricted to a few coastal sites in Cornwall, the Isles of Scilly, and Wales.


Sunny, mossy or grassy cliffs.

Key threats

The main threats are smothering by ivy, bracken or gorse, which also poses a fire risk, and potentially also trampling by visitors on the South West Coast Path which passes near to some populations.
