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