• Lepraria sylvicola Orange

There are no records for this species at present.

Collected only from north Kerry and west Donegal, L. sylvicola can be a difficult species to nail. Look for brown patches of hyphae in cracks below the otherwise blue-grey powdery thallus that test K+ purple-red. The species is known to favour the bark of sessile oak in the semi-natural woodlands of the west. Chemical analysis is required for certain identification.
