About plant names...

The term "honey mushroom" applies to more than one member of this species. They live on trees or woody shrubs. They are parasitic—they attack living plants, as well as on deadwood. Sometimes, for reasons not yet understood, they "go crazy," causing extensive root rot and destruction.

Identification: Typically the caps are yellow-brown in color. They may be sticky when wet. The caps are convex when the mushrooms are young, but may become concave later. Some are bioluminescent—they glow in the dark. The spores of this mushroom are white.

Armillaria mellea (honey mushroom, honey fungus)

The mycelium that produces honey mushrooms is bioluminescent, creating a soft glow in rotting wood sometimes called "foxfire."

Edibility: Young buttons are very good if the stipe is discarded (or peeled) and the buttons cooked.
