Cladonia uncialis (L.) F.H.Wigg.
subsp. biuncialis (Hoffm.) M.Choisy
Mature podetia without basal sqamules, individual or in loose clusters, whitish to pale yellow-green or grey-green, hollow, thin-walled and brittle, seeming inflated (especially in oceanic Britain), finely powdery on the inner surface (at least in the upper parts), irregularly dichotomously and trichotomously branched, the branches short and stubby, not forming cups but often terminating in clusters of 2 (to 6), small branches surrounding a central hole, the ultimate branch tips pink-brown and usually dichotomously forked; apothecia brown, very rare. Heaths and moors, widespread, locally very common in the north and west, often lying fragmented on the peat surface.
Much more common in Britain than subsp. uncialis.
