American Slippery Cap or Chickenfat Mushroom , Suillus americanus
Suillaceae or Slippery Cap Family


Medium mushroom, up to about 5 inches across. Cap yellow, slimy, decorated with red brown scales and fibers, Stalk yellow with red-brown markings. With sufficient imagination one could believe that someone had skimmed off the fat from a cooked chicken and dumped it on the ground. A member of the general group called boletes which have pores instead of gills; spores are borne in the pores and released. Pore surface yellow, spongy. Found on the ground in summer or fall, under eastern white pine.

It is mycorrhizzal on pine roots, which means that the fungus grows into the roots and cooperates with the pine; it supplies the pine with minerals pulled from the soil, and the pine provides sugars. Occasionally seen in Wildwood.

Readily identified by its pores and color scheme.
