Gomphidius smithii, commonly known as Smith's slime spike,[2] is a species of mushroom in the family of Gomphidiaceae. It is found in the Pacific Northwest.[3][4] It accumulates heavy metals.[2]

Description

The cap of Gomphidius smithii is about 1.5-7 centimeters in diameter. It starts out rounded, before becoming convex and eventually flat. The surface of the cap is slimy.[2] The stipe is about 4-7 centimeters long and 0.5-1 centimeters wide, with a veil. Unlike many other Gomphidius species, G. smithii is not yellow at the base of the stipe.[5] The gills are decurrent and start out white, before graying with age.[2] The spore print is dark gray, sometimes almost black.[5]

Habitat and ecology

Gomphidius smithii is found under douglas fir trees.[2] It grows in association with and is likely parasitic to Suillus lakei, a mycorrhizal fungus that grows in association with douglas fir. It may also grow in association with other Suillus species.[6]
