Fuscidea multispora is a species of foliicolous (leaf-dwelling), crustose lichen in the family Fuscideaceae.
Found in Bolivia, it is known to occur only in a single high-altitude locality in a national park, where it grows on the leaves of coniferous trees from the genus Podocarpus.
The type specimen was collected from Carrasco National Park (Cochabamba Department) at an altitude of 3,283 m (10,771 ft); here, it was found by the first author growing on the leaves of a Podocarpus tree.
[1] The lichen has a greyish-green to brownish thallus with a verruculose surface texture (as if covered with tiny warts); it reaches a diameter of 3–6 mm (0.12–0.24 in).
Fuscidea multispora contains sekikaic acid, which is a lichen product that can be detected using thin-layer chromatography.
