Cladonia mediterranea Cladonia mediterranea

Best Time to See
Habitat Heathland

A low, pale grey, branching lichen.

Although it bears considerable resemblance in the field to the common species Cladonia portentosa, laboratory research has recently confirmed that it is a species in its own right, rather than just a different form of the commoner species.


Confined to the Lizard peninsula in Cornwall.


Short grassy areas of open heathland.

Key threats

The main threats are the risk of fire and insufficient grazing which would allow coarser vegetation to smother it and increase the fire risk.
