Xanthomendoza fallax fungi kingdom
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. The nonfruiting body (thallus) grows in rosettes to 3 cm in diameter. The rosettes sometimes coalesce with each other. The lobes may appear divided at the tips. It is sometimes tightly appressed to the substrate (adnate), and sometimes not. 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. The tips of the lobes form hood shaped soralia that produce powdery greenish yellow soredia. It prefers growing on oak bark in California, but can also be found on rock and other wood. Lichen spot tests on the surface are K+ purple, C-, KC-, and P-.
