Xanthomendoza fallax (hooded sunburst lichen) is a small yellow-orange to red-orange foliose lichen that grows on bark or rarely on rock or bone.[1] It is found all over the world except very dry areas, with 10 species common in North America.[1][2]:130[3] The nonfruiting body (thallus) grows in rosettes to 3 cm in diameter.[2][3] The rosettes sometimes coalesce with each other.[3] The lobes may appear divided at the tips. It is sometimes tightly appressed to the substrate (adnate), and sometimes not.[2][3] 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.[2] The tips of the lobes form hood shaped soralia that produce powdery greenish yellow soredia.[2] It prefers growing on elm or oak bark, but can also be found on rocks, bone, or other wood types.[2] Lichen spot tests on the surface are K+ purple, C-, KC-, and P-.[2]
