Hydnum Azure grows on rocks all over the Mania side of the Shivering Isles. They may also be found on the island with the Strange Door. They only grow from the sides of objects like boulders, buildings, or large roots. The plant is large enough that it can be used as a platform to scale the sheer edifices it tends to grow on. The residents of Mania consume the plant's spores as part of their regular diets.
