Leccinum manzanitae  Leccinum manzanitae is an edible species of bolete fungus in the family Boletaceae. Described as new to science in 1971, it is commonly known as the manzanita bolete for its usual mycorrhizal association with manzanita trees. Its fruit bodies (mushrooms) have sticky reddish to brown caps up to , and its stipes are up to long and thick. They have a whitish background color punctuated with small black scales known as "scabers". Found only in the Pacific Northwest region of the United States and Canada, it is the most common "Leccinum" species in California. The mushroom is edible, although opinions vary as to its quality. "L. manzanitae" can be usually distinguished from other similar bolete mushrooms by its large size, reddish cap, dark scabers on a whitish stipe, and association with manzanita and madrone. "Leccinum manzanitae" was first described by the American mycologist Harry Delbert Thiers in 1971, from collections made in San Mateo County, California, the previous year. In that state, it is known as the manzanita bolete because of its close association with manzanita trees. It is classified in subsection "Versicolores" of the section "Leccinum" in the genus "Leccinum". Closely related species in this section include "L. piceinum", "L. monticola", "L. albostipitatum", and "L. versipelle". The fruit bodies of "Leccinum manzanitae" are sometimes massive, occasionally reaching weights of several pounds. The cap is in diameter, spherical to convex when young, and broadly convex to flattened or cushion-shaped (pulvinate). The surface of the cap is often shallowly to deeply pitted or reticulate, sticky, and covered with pressed-down hairs that are more conspicuous toward the edge of the cap. Its color is dark red during all stages of development. The cap's flesh is thick, white when first exposed, but slowly and irregularly changing to dark brownish-gray with no reddish intermediate state. The change in color upon bruising or injury is often more pronounced in young specimens. The tubes comprising the hymenophore are long, with an adnate attachment to the stipe; their color is pale olive when young and darkens when bruised.
