Taxonomy
Pseudoboletus parasiticus is one of the earliest-diverging lineages of the Boletaceae, after the clade comprising Chalciporus and Buchwaldoboletus.[1]
Description
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
It can be found growing on Scleroderma citrinum earthballs in eastern North America from July to September.[2]
Edibility
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]
