Slimy spike

Gomphidius glutinosus

A species of Spike-caps, Also known as Slimy spike cap, Hideous Gomphidius

A stocky, almost imposing mushroom, the slimy spike (Gomphidius glutinosus) has a round bulbous cap and a very thick stalk. This species is one of the more unusual members of the bolete order (Boletales) because it has gills, rather than a spongey pore surface. The "slimy" in this species' common name is well-earned - individuals are almost always coated in a shiny layer of slime.

Cap Diameter:

3 - 15 cm

Odor:

Mild, non-distinctive earthy aroma.
