Ramalina cuspidata Chem. cuspidata forma cuspidata

    This chemoptype or form is rather common, and might be considered as the Ramalina cuspidata type. Most often pendent, seldom erect, branches thin, narrow, elongate, mostly terete on their entire length, ivory, cream, whitish,  bases and apices most often blackish. Apothecia, Basque beret-shaped, rare and when present, scarce. On dry vertical walls of rocks in the xeric supralittoral zone. N.B. Seems, at least in part, to correspond to Ramalina cuspidata Chem. b (C-, K+ yellow +/- orange, KC+ yellow, Pd+ orange). N.B. Very close to Ramalina cuspidata Chem. cuspidata f. armorica of which determination is difficult or uncertain (also Chem. b) since the branch section trait is not fully reliable.*
