Honey mushrooms (Armillaria mellea) are all over the Bay Area right now! Thank you rain! Some fun facts about honeys: - they are edible & delicious but CAN cause GI issues for some people and if they are not cooked thoroughly - they are the world’s largest organism! The humongous fungus! A single Armillaria mellea colony in Oregon’s Malheur National Forest spans over 2k acres, making it the largest living organism on Earth by area. It’s estimated to be ~2,500 years old, though it could be much older - the mycelium (the underground network of fungal threads) of Armillaria mellea can glow in the dark - they are a parasite that can kill trees and woody plants by invading their roots. It’s considered a major forest pathogen and is sometimes called the “shoestring fungus” because of the black rhizomorphs (root-like structures) it forms. To identify Armillaria mellea: - Cap should be HONEY-brown to yellowish-brown, often darker in the center. Could have some little scales. Size could range from 1cm–6 inches in diameter. Convex when young, flattening with age. - Gills are usually adnate to decurrent (attached and running slightly down the stem). Gills are white to cream, yellowing with age. - For ringed honeys like in this video, the stem has a white or yellowish ring near the top of the stem. Fibrous (rips like string cheese). - Spores are WHITE. You can verify this by taking a spore print: place the cap gill-side down on a piece of dark paper overnight. - they usually grow in clusters at the base of trees, stumps, or buried wood. It is parasitic and saprobic (feeds on both living and dead wood). - you might even be able to find the mycelial rhizomorphs (“Shoestrings”) if you look for black, root-like threads under the bark of infected trees or in the surrounding soil. These rhizomorphs are a hallmark of honey fungus. As always DO NOT eat anything you’re not 1000% sure of!! :) You can join me on a mushroom walk in the Bay Area - waitlist is on my page!
