Honey Mushroom Identification: Armillaria and Lookalikes

This page is for identification, not a guide to eating wild mushrooms. The honey mushroom's most dangerous lookalike, deadly galerina, contains the same amatoxins as the death cap, the toxins behind more than 90% of fatal mushroom poisonings (Wikipedia). MushroomExpert.com, a leading North American identification site, notes that some Armillaria species cannot be told apart without mating studies or DNA. A photo, an app or this page is not enough to decide a mushroom is safe; that decision needs an experienced person examining the actual specimens.

If someone has eaten a wild mushroom and feels unwell, or you do not know what they ate, call Poison Control at 1-800-222-1222; call 911 if they collapse, have a seizure, have trouble breathing or cannot be woken (poison.org). Keep a sample of the mushroom for the experts.

Honey mushrooms grow in dense clusters at the base of living or dead trees and on stumps, usually after rain in late summer and fall (Wikipedia; MushroomExpert.com). Check each of these:

• Cap: 3 to 15 cm, honey-colored, golden yellow when young and fading to yellowish or brownish, sometimes with small dark hairy scales toward the center (Wikipedia; MushroomExpert.com). PEI Untamed describes young caps covered in hair-like projections, darker at the center.
• Gills: whitish, later pinkish or brownish, attached to or running slightly down the stem; covered by a pale veil when young (MushroomExpert.com).
• Stem: 7 to 20 cm long, tapering at the base where clustered stems join, with a thin but persistent white ring, often with a pastel yellow edge (MushroomExpert.com).
• Spore print: white.
• Rhizomorphs: black, bootlace-like strands under bark and in soil, which spread the fungus from tree to tree (Wikipedia). Its mycelium also glows faintly when actively growing.

The spore print is the single most useful check against deadly galerina. Our method: cut the cap from the stem, set it gills-down on paper that is half white and half dark, cover it with a bowl, and leave it for several hours. Honey mushrooms drop a white print (Wikipedia). A rusty-brown print rules out a honey mushroom and points toward galerina (Wikipedia). Wash your hands after handling any wild mushroom.

Wikipedia lists Armillaria mellea among the mushrooms deadly galerina is confused with. The differences:

• Spore print: honey mushroom white; galerina rusty brown.
• Size: galerina caps are 1 to 6 cm, brown to yellow-brown; honey mushroom caps reach 15 cm.
• Gills: galerina's are pale brown when young and tawny at maturity; honey mushroom's are white at first.
• Ring: galerina has a membranous ring on the upper stem, but it can fall off in older specimens; a missing ring does not prove anything.
• Where: galerina grows on decaying conifer wood from summer to autumn, overlapping the honey mushroom's season.

Amatoxin poisoning causes severe abdominal pain, vomiting and diarrhea, then liver and kidney damage, and can kill within about a week (Wikipedia).

• Jack-o'-lantern (Omphalotus illudens): a large orange mushroom up to 15 cm growing in clumps on stumps, buried roots or at the base of hardwoods in eastern North America. Its gills run down the stem and often glow a weak green when fresh. Its spore print is white to cream, so the spore print does not separate it from honey mushrooms; its orange color and gills running down the stem do. It contains illudins, which cause vomiting, cramps and diarrhea (Wikipedia).
• Other Armillaria species: MushroomExpert.com counts about 9 to 10 in North America, some of which look identical. Wikipedia notes that Armillaria gemina lacks the yellow background on the cap.

Treat any clustered mushroom on wood that does not show all the honey mushroom features above as unidentified.

We do not answer this for any particular mushroom. What the sources say: Wikipedia describes the honey mushroom as edible but says it must be cooked, and that specimens from some hosts, such as buckeye or hemlock, can cause gastrointestinal upset; PEI Untamed, a beginner forager's blog, also stresses long cooking and confirming the identification with someone more experienced. MushroomExpert.com deliberately gives no edibility information.

Taken together with the deadly galerina risk above, the only responsible advice is: do not eat any wild mushroom based on a photo, an app result or a web page. Have the specimens examined in person by an experienced local identifier, such as a mycological society.

For gardeners the bigger concern is the tree. Armillaria is a parasite of broadleaf trees and conifers that causes a serious root rot and large economic losses (Wikipedia). UGA Extension's oak disease key lists Armillaria root rot as serious: crown dieback, slower growth, early leaf drop and white fans of fungus between the bark and wood. A ring of honey mushrooms at the base of a declining tree is a reason to call an arborist. See our oak tree fungus identification page for the other symptoms.

For the app or an expert, photograph: the whole cluster where it grows, including what wood it is on; the top of a cap; the gills from below; the stem with its ring; the base where the stems join; and the spore print next to the mushroom. NatureLens can suggest a species from these photos, with free scans every day. For mushrooms, use the result to guide what you check next, never as a decision to eat.
