Cladonia verticillata (Hoffm.) Schaer

Synonyms:

Cladonia cervicornis subsp. verticillata (Hoffm.) Ahti



Family: CLADONIACEAE

Habitat: Aerohaline zone

Description

   Differs from  Cladonia cervicornis subsp. cervicornis by its basal squamules, much smaller or absent, lacking whitish colour on lower surface, and markedly smaller in size than podetia. Podetia grow as proliferating tiers from the center of scyphi, up to 2-3 levels and 2-3 cm tall as conspicuous scaffolds. Rather rare, grows on sandy soils of aerohaline heathlands, always in combination with other Cladonia species. N.B. The local tradition is to use the same name for specimen of  Cladonia cervicornis subsp. cervicornis of which podetia are organised in several levels. They may be a local form of Cladonia verticillata, of which the canonical form is different without or with little squamules towards the base and short podetia piled up in 4-5 levels from the syphus center, to 2-5 cm tall, bronze or brown-greenish.
