Boletus
(from bolos, a mass; in reference to its massy or globular form). ORD. Fungi. The only species of this rather large genus demanding mention is B. edulis, which is considered an excellent article of food. It is easily distinguished, and is often of large size and somewhat unshapely; the pileus is usually of a dusky yellow or brownish hue, but sometimes brighter and more of a chestnut colour; the flesh is white, and does not change to a blue colour when cut (this is a very important characteristic, and should always be noticed). It is a species common in most districts, usually growing in woods, and appearing chiefly in the autumn.
