Taxonomy
editDescription
editThe 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
editXerocomellus 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]
Habitat and ecology
editXerocomellus diffractus is a mycorrhizal fungus, found growing under trees.[1][6] Grow solitary or scattered in troops under both conifers and hardwoods. Fruiting in fall and early winter, or occasionally in spring on the California and Oregon coast, and summer in the Southwest, and at higher elevations.[7]
