Cladonia uncialis (L.) F. H. Wigg. subsp. uncialis
This taxon is very similar to Cladonia uncialis subsp. biuncialis but differs by its tufts displaying a higher density of podetia more or less erected, predominantly tetra to hexachotomously branched, short terminal branchlets -not whitish powdery- often brown-pinkish towards pointed apices of the podetia, giving a star-like appearance around the central axils (resembles to a cup or a crown). Pycnidia and apothecia rather frequent. Photobiont : trebouxioide. On grey dunes and acid sandy or gravelly soils, much more uncommon than subsp. biuncialis. N.B. Formerly these two taxa were not separate or considered as morphotypes or varieties and hereafter we present our pictures with the usual restrictions as far as the subsp. uncialis is considered, since many puzzling intermediate specimen seem to be found and are difficult to assign to one or the other subsp.; a picture of this taxon taken in the Alps is presented for comparison. N.B. Many modern authors do not distinguish between the two subspecies.
