Pineapple (now termed pine cones). When European explorers encountered this tropical fruit in the Americas, they called them "pineapples" (first referenced in 1664, for resemblance to pine cones). In the scientific binomial "Ananas comosus", "ananas", the original name of the fruit, comes from the Tupi word "nanas", meaning "excellent fruit", as recorded by André Thevet in 1555, and "comosus", "tufted", refers to the stem of the fruit. Other members of the genus "Ananas" are often called pine, as well, in other languages. The pineapple is a herbaceous perennial, which grows to tall, although sometimes it can be taller. In appearance, the
Boletellus ananas of "B. ananas" is wide and plano-convex (flat on one side and rounded on the other).

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
