The Genus Gomphidius
[ Basidiomycetes > Boletales > Gomphidiaceae . . . ]
by Michael Kuo
The mushrooms in Gomphidius are slimy-capped conifer lovers with dark gray to black spore prints, gills that run down the stem, and stems that are often--though not always--bright yellow near the base. The flesh in the cap and stem is white, and observation of this feature is sometimes the best way to separate species of Gomphidius from species of Chroogomphus, which can appear similar.
Recent research has placed Gomphidius and Chroogomphus within the Boletales, near the genus Suillus. Perhaps this is not a big surprise, since species of Suillus are the slimy conifer lovers among boletes.
