Cladonia cornuta (L.) Hoffm.


Podetia grey-green, rather robust, tapering to a point, unbranched or sometimes forked, sorediate in upper part, corticate in lower half, usually squamulose near base, becoming brownish with age, primary squamules not persisting; apothecia very rare, brown, on the tips of the podetia. Widespread but generally rare, more frequent in the Scottish Highlands, predominantly in montane and dune heaths, said also to occur on rotting wood.
