Description

The roughly spherical to irregularly shaped fruitbodies of the fungus measure 10–21 mm (0.4–0.8 in) in diameter when fresh, although they tend to shrink when dry. They have a hard, wrinkled surface that is yellowish brown or lighter in color. The peridium is 300–570 µm thick. The spores have the shape of narrow ellipsoids, and rarely exceed 5 µm in length. They often contain two oil droplets, but occasionally have three or four.[1]

Habitat and distribution

The fungus is only known from Fort Smith (Northwest Territories), and Newfoundland. In the former location, it was found along a riverbank in spruce woods, while in the latter it grew on mossy slopes in thickets of alder and fir.[1]
