Armillaria solidipes

Armillaria solidipes
(Honey Mushroom, Shoestring Root Rot, Armillaria mellea)


Grows in the woods, usually at the base of tree stumps. It is typically associated with Aspen in Colorado although sometimes they're found with conifers too. They typically show up later into the season. The first week of September is a good time to go out and look for them in Aspen groves.


Also known as Shoestring Root Rot. Black rhizomorphs grow underground spreading the disease from tree to tree which resemble shoe strings. Armillaria species are considered a tree pathogen and are responsible for killing many trees each year.

They are considered edible when well cooked for most people. Some people have adverse reactions as these mushrooms do contain toxins which can cause gastrointestinal upset. It is my understanding that there are many toxins which are still being studied. They are considered mildly poisonous raw.

We also have another similar ringless honey mushroom.
