BOLETES: SPONGE-PORED FUNGI

Boletus subvelutipes, Suilliellus subvelutipes 1739

Generally boletes have a hemispherical to convex cap, soft flesh, and a layer of attached vertical tubes beneath the cap flesh in which spores are produced and are released. Cap and stem colors commonly change as the fruiting bodies age. This is why mycologists recommend gathering several of the same speciers representing different degrees of maturity. The cap is typically held up by a stem, which may or may not feature addditional characteristics common to genera within the family. A number of boletes, but not all, depending on the species slowly or instantly stain a color in response tp handling and exposure to air. In some, the color may change over time. These and other characteristics are important for learning to identify this important group of mycorrhizal fungi. Some are associated with broad-leaf trees, others with conifers, and some are relatively cosmopolitan.

The above photo of the red-pored Boletus subvelutipes shows the white flesh beneath the cap skin, and the yellow tubes and stem which have instantly turned blue on exposure to air with handling and cutting.
