From Wikipedia, the free encyclopedia

The non-fruiting body (thallus) grows in rosettes to 3 cm in diameter.[3][4] The rosettes sometimes coalesce with each other.[4] The lobes may appear divided at the tips. It is sometimes tightly appressed to the substrate (adnate), and sometimes not.[3][4] The fruiting bodies (apothecia) are lecanorine, meaning that they are disc-like with a ring or rim of tissue around the disc that is made of tissue similar to the thallus.[3] The tips of the lobes form hood shaped soralia that produce powdery greenish yellow soredia.[3] It prefers growing on elm or oak bark, but can also be found on rocks, bone, or other wood types.[3] In Norway, it has been recorded growing on the bark of various sun-exposed broadleaved trees, including Acer, Betula, Fagus, Fraxinus, Populus, Tilia, and Ulmus.[6] Lichen spot tests on the surface are K+ (purple), C−, KC−, and P−.[3]
