Ramalina siliquosa chem d = chem 0 sans acides lichéniques.
Chem d = Chem 0: C-, K-, KC-, P-. UV-. This taxon forms small bushes with branches in wide strips, cream-ivory, with few crevices and sometimes small nodules (pycnidia). Apothecia usually numerous, emerging at the margin of the strips, flat to domed disc, cream-pink to cream. Rare taxon (or neglected for lack of chemical tests?) coming on siliceous rocks, little or not acidic, of the xeric supralittoral zone. N.B. Taxon often parasitized by Stigmidium epiramalina and in this case not to be confused with Ramalina cuspidata.
