Herteliana gagei forme saxicole des chemins

   This morph is characterized by its thallus, surface slightly coarse and not smooth, green to green-bluish, found mainly at the base of rocks and boulders at the junction with the ground in (or bordering) pathways in oceanic woodlands and forests, more seldom at the base of old walls, usually in better-lit areas subjected to direct sun light than the canonical Herteliana gagei type. On mossy rocks, it eliminates all the bryophytes and the thallus margin is devoid of prothallus. Most often sterile but, sometimes, sections with aborted and immersed apothecia surrounded by pycnidia may be observed.N.B. Not to be confused with Baeomyces rufus  that grows on the ground, granulose and Pd+ orange.
