Gomphidius

About

Gomphidius is a genus of mushrooms, commonly known as spike-caps, that are members of the Boletales, or pored fungi. They appear to have gill-like structures which resemble those of agarics, however the similarity is superficial only. The best-known member is the slimy spike-cap. The genus has a widespread distribution, especially in north temperate areas, and contains 10 species.
