Cladonia furcata subsp. subrangiformis (L. Scriba ex Sandst.) Pisut

    Differs from Cladonia furcata subsp. furcata s.l., by its colour, darker and more brownish, olive-brown, dark brown; podetia markedly intertwined in shorter and denser tufts. Podetia also covered towards the base by branched excressences or white farinose warts (calcium oxalate concretions). Fertile specimen rare, apothecia subspherical, 0.5-1 mm diam., corymbose, at apices of some branches. Thallus : C-, K+/- pale yellow, KC-, Pd+ red. Rather common, on calcareous or dry calcified dunes (Toninion sedifoliae). This taxon is sometimes considered as an ecotype or a variety. N.B. Some taxa ranked as varieties or morphotypes by the authors of  Cladonia furcata subsp. furcata s.l.  (and more specifically Cladonia furcata subsp. furcata var. palamaea) should not be mistaken with the present taxon which seems mostly present in West France.*
