Xerocomellus diffractus, commonly known as the cracked-cap bolete,[1] is a species of mushroom in the family Boletaceae. It is found in western North America.[2]
Description
The cap is brownish and 3.5–9 centimetres (1+1⁄2–3+1⁄2 in) wide.[3] It develops cracks as it gets older.[1][4] The cracks start out pale to whitish, and turn pinkish as the mushroom gets older.[1] The stipe is 4–9 cm (1+1⁄2–3+1⁄2 in) tall and 7–18 millimetres (1⁄4–3⁄4 in) wide.[5] The flesh is whitish in the cap, yellow in the stem, and stains blue. The spore print is olive brown.[3]
Xerocomellus diffractus sometimes slowly bruises blue.[1][5]
Similar species
Xerocomellus diffractus can be confused with several other species of mushrooms, including X. amylosporus, X. mendocinensis, X. salicola, X. rainisiae, and X. chrysenteron. However, X. amylosporus, X. mendocinensis, X. salicola, and X. rasisiae bruise blue quicker and more intensely, and X. chrysenteron is found in Europe.[6]
