Description
Cap: Hemispheric to convex, shades of brown, velvety to smooth; flesh pale yellow. Pores: Yellow to olivaceous, occasionally with rusty stains. Stalk: Nearly equal, usually curved, yellow densely covered with dark fibrils; white / pale yellow mycelium at base.
Relationships
Found solitary or in small groups attached at base to fruiting bodies of Common Earthball (Scleroderma citrinum). Although commonly referred to as "parasitic," the relationship may be much more complex. Usually found in hardwood forests (oaks) or mixed forests with hemlocks. (J. Solem, pers. comm.)

Pseudoboletus parasiticus, previously known as Boletus parasiticus and Xerocomus parasiticus, and commonly known as the parasitic bolete, is a rare bolete mushroom found on Scleroderma citrinum earthballs in North America.
Taxonomy
[edit]Pseudoboletus parasiticus is one of the earliest-diverging lineages of the Boletaceae, after the clade comprising Chalciporus and Buchwaldoboletus.[1]
Description
[edit]The cap is hemispherical when young,[citation needed] later flat, yellowish brown or darker and up to 6 centimetres (2+1⁄4 in) wide.[2] The yellow stem is 3–7 cm (1–3 in) tall and 6–15 millimetres (1⁄4–5⁄8 in) thick.[2] The flesh is pale yellow and the spore print is olive brown.[2]
Habitat and distribution
[edit]It can be found growing on Scleroderma citrinum earthballs in eastern North America from July to September.[2]
Edibility
[edit]While edible, it is not recommended to do so, due to concerns about being poisoned by its host, the common earthball, which is poisonous.[3]
