The outcrops ofalkaline volcanic rock from southeastern Spain, in a more or less thermic and arid climatic conditions, show lichen communities contrasting with that studied on acid lava in the same region in: a. Presence of nitrophilous species, mainly silicicolous. b. High presence of calcicolous species, rarely seen on siliceous acid rocks. c. Lack of good number of species typical of the siliceous rocks of SE Spain. d. Prevalence of communities of Peltulion euplocaeand Caloplacion irrubescentis, and absence of them included in the alliances Dimelaenion radiatae and Lecanorion montagnei. A list of 88 species recognized is also afforded. A new subassociation, Acarosporetum heuflerianae subas. caloplacetosum teicholytaeis described.
