Flavoparmelia caperata forma laevissima Gyeln.

    This morph differs from the canonical type Flavoparmelia caperata f. caperata by its thallus, smooth, without soredia and isidia (or extremely rare) even on apothecia exciple. Common on acid tree barks and also on rocks. There, this morph can be identified by its pleated lobes and its chemical spot tests. N.B. Simple form because there are all forms of passage with the type.
