Boletus mirabilis
Common: Admiral Bolete
Description: Cap 5-15cm across, convex to flattened, margin inrolled; vinaceous, dark to reddish violet brown when young, fading to brown to dark brown; moist to soon dry, woolly or even squamulose. Pores yellow-white to olive-yellow; depressed around stem; not staining or staining slightly darker yellow when bruised. Stem 80-150 x 35-50mm; bulbous to club shaped; dry; dark to reddish brown with darker striations. Flesh firm; white, yellow with greyish red streaks in stem. Odor and taste pleasant. Spore print olive-brown.
Habitat: On or near logs or woody debris of fir, hemlock, or western red cedar, Sept - Dec.
Primary keys: bolete round pores; red/brown velvety cap; yellow pores not staining blue; dark reddish-brown stem with streaks; grows on wood
Edibility: Good - it has a slight lemony note under a mild bolete flavor.
Notes: This distictive and common bolete is easy to identify. B. chrysenteron has a lighter cracked cap while B. zelleri has a more red cap. Both have more yellow in the stem with fewer if any striations, the pores typically stain blue, sometimes slowly, and they are terrestrial not wood-lovers. All are frequently attacked by the white-to-yellow cottony Hypomyces chrysospermus, a cousin to the Lobster Mushroom. B. mirabilis - like other boletes - is an excellent mushroom for drying. And like other boletes, beware of worms!
