Occurrence

Very common

Season

July to October

Habitat

Mixed and deciduous forests. On the ground under eastern white pine.


Identification

When young the cap is convex, bright yellow, and slimy, and the margins are curled under. The cottony remnants of the veil are usually attached to the inside of the margin. As the mushroom matures the cap becomes dry, tacky, and broadly convex to flat. It often has brown streaks, especially near the margin, and sometimes has a small bump (umbo) in the middle.

The stalk does not show the remnants of the veil. It is covered with glandular dots that bruise brown when handled.

There are no gills. The pore surface on the underside of the cap is tightly packed pores.

This chicken-fat mushroom footage strikes me as extremely interesting. The colouration, textures, and morphology are all quite enigmatic. The fungus derives some of its nutrients through a mycorrhizal association with the roots of eastern white pine, receiving carbohydrates from the tree and providing it with minerals that the fungus' extensive mycelium (its "root" structure) collects. It also has pores instead of gills on its underside! They desiccate to beautiful black/brown/yellow hues in this footage.
