Cladonia alpina
Resembles Cladonia macilenta but the podetia are distinctly taller, up to 4 (–5) cm in height, usually bifurcate or sparingly dichotomously branched in the upper part. Podetia variably sorediate with soredia farinose to subgranular. Thallus C–, K–, KC–, Pd– (or rarely P+ yellow), UV– (barbatic and porphyrilic acids, also thamnolic acid, ± frequent).
Not well known in Britain and the British material needs re-evaluation. An unusually large Cladonia macilenta like material in the uplands should be looked at carefully.
On soil rich in humus and on lignum, also on soil over rocks and walls and on Birch trunks.
Rare. N. and S. Wales, England (Lake District), Scotland (W. Ross) (some records not localised, so not on the map).
Assessed as Data Deficient.
