Extract from Wikipedia article: Chroogomphus rutilus, commonly known as the brown slimecap or the copper spike, is a species of fungus in the Gomphidiaceae family. First described scientifically as Agaricus rutilus by Jacob Christian Schaffer in 1774, it was transferred to the genus Chroogomphus in 1964 by Orson K. Miller, Jr.. The fungus lives ectomycorrhizally with Pinus species, and is found in Europe and North America. The fruit bodies are edible but not highly regarded.
Chroogomphus rutilus is a species of fungus that belongs to the family Gomphaceae. It has a reddish-brown to orange-brown cap and yellow to greenish-yellow stem. In St. Petersburg and Leningrad Oblast, it typically grows in coniferous forests, especially with pine and spruce, from August to October. In north-western Russia, it is widely distributed and can be found in similar habitats, often forming mycorrhizal relationships with tree roots. The fungus is considered edible and is sometimes picked for food in the region.
