Parasitic Bolete - Pseudoboletus parasiticus

    Alt Name
    Xerocomus parasiticus
    Description

    The cap is hemispherical and downy when young, later flat, yellowish brown or darker and up to 5 cm in diameter. The flesh is pale yellow with a mild taste and the spores are olive. The stem is pale yellow to olive. Pseudoboletus parasiticus is unlikely to be confused with any other species, because it occurs only with the Common Earthball, Scleroderma citrinum.
