It belongs to 'Cladonia pyxidata' group of lichens having trumpet like podetia when not sterile. There are several members of this group not always easy to be determined to species level. They usually have very similar, small ground (primary) squamules. The size, shape, surface of podetia and color of eventually present apothecia or pycnidia are important distinguishing field characters, chemical tests help a lot in confirmation of determinations. Cladonia fimbriata has slender, stout podetia, with relatively shallow cups (abruptly joined to long stalks in mature podetia) with mostly even margins except when fertile having apothecia or pycnidia (in the form of small brown dots - see Fig. 14). Their surface is allover covered by very small, farinose soredia and sometimes with relatively few, if any, small secondary squamules. (1) V.
