BOLETUS, L. Touchwood. Fungi with pores beneath; we have nearly 200 species: those with cells beneath are my G. Phorima; Polyporus has a central stem, Dedalea a labyrinth beneath, Fistulina hollow tubes beneath. The true Boletus are sessile, equivalent to Agaricus to make tinder and styptic lint. A. cinnabarinus dies red. B. suberosus is made into corks in Sweden. B. igniarius and B. fomentarius chiefly used for spunk or tinder. B. marginatus exudes an acid. B. odoratus and B. suaveolens smell like anniseed, their powder preserves clothes from insects, used in Europe with honey in phthisis. The B. laricis is tonic and used in fevers. Almost all the fleshy species of Polyporus are edible (Do NOT trust this! -Henriette), test same as for Amanita, B. edulis, B. juglandis, &c. are excellent.
