Pseudoboletus parasiticus

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

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 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, which is poisonous. ^[3]
