This is one our most distinctive lichens of damp siliceous rocks and stream edges. By its grey, warty, granular squamules (phyllocladia) it is instantly recognisable as a species of Stereocaulon but it is the erect stalks called pseudopodetia, each capped with a globe of soralia like a round-headed mapping pin, which makes it stand out from the crowd. Discs are rare. In Ireland, the species is scattered.

Key characteristics
