Oxneria fallax, also known as the hooded sunburst lichen, is a small yellow-orange to red-orange foliose lichen that grows on bark or rarely on rock or bone.

[2][3]: 130 [4] The non-fruiting body (thallus) grows in rosettes to 3 cm in diameter.

[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.
