the species is therefore Boletus ananas M.A. Curtis 1848, the basionym of Boletellus ananas. Boletellus ananas, as the type species of the genus Boletellus, is in section Boletellus that Singer based on the scaly, dry cap with red-pink tones, a marginal veil that clasps the stem when immature, and longitudinally ridged spores that are greater than 16 μm long. The genus name Boletellus means "small boletus", while the specific epithet ananas alludes to the name for pineapple, referring to the pineapple-like pattern of scales on the cap surface. The mushroom is commonly known as the "pineapple bolete". Description The cap of B. ananas is wide and plano-convex (flat on one side and rounded on the other). It is covered with squamules (small scales) that can be either pressed against the cap or curved back on itself. The squamules range in color from reddish brown to red-tan, to pink to pinkish gray, and they are more concentrated and more scaly in the center of the cap, extending out of cream to light orange-pink to light pink-red floccose ground. The margin clasps the stem when young; at maturity it separates into triangular veil remnants (appendiculae) that measure 6–12 by 3–10 mm. The color of these appendiculae range from buff-white to faint pink. The flesh is 2–3 mm thick at the edge of the cap, 7–10 mm over the tubes, and 11–18 mm centrally. It is buff white to light yellow, and quickly turns bluish upon exposure to air. The tubes are 1–5 mm long at the margin, 10–20 mm in the center, and 4–6 mm at the stem. They are broadly and deeply depressed around the stem, of irregular lengths, bright yellow to olive-yellow to mustard-yellow, and also rapidly turn blue upon exposure. The pores are the same color as the tubes, and rapidly turn blue-green with pressure; they are angular, and there are about 0.5–1.5 pores per mm. The stem is by wide, and gradually becomes larger towards the base to 10–19 mm. The top part of the stem is cream to pink, the middle finely longitudinally striate, with the striations darkening with handling, red-lavender to brown-red, lighter with age. Immediately above the basal tomentum the stem surface is cream-colored with few striations. The basal tomentum is made of stiff, coarse white hairs over the lower 6–50 mm. The flesh of the stem is solid (i.e., not hollow) white to buff-tan
