Deadly galerina vs honey mushroom: how to tell them apart

Quick answer

A honey mushroom's spore print is white, often visible as white dust on the lower caps of a cluster; the deadly galerina's is rusty brown. The galerina is also smaller: its stems are usually under a quarter inch (0.6 cm) thick and caps rarely pass 1.5 inches, while honey mushrooms are larger, with small dark hairs or scales at the cap center.

Deadly lookalike

The deadly galerina can be fatal.

Unlike the honey mushroom, the deadly galerina (Galerina marginata) contains amatoxins, the same toxins as the death cap, at similar concentrations, according to the University of British Columbia's Mushrooms Up! guide. Amatoxins stop cells from making proteins by blocking the enzyme RNA polymerase II. The Bay Area Mycological Society records that symptoms usually begin 6 to 24 hours after eating, followed by an apparent recovery and then liver damage from about 72 hours. Cooking does not destroy amatoxins.

If someone has eaten a wild mushroom and feels unwell, or may have eaten one of these, call poison control now: 1-800-222-1222 in the US. Do not wait for symptoms.

FAQ

Common questions

How do you tell a honey mushroom from a deadly galerina?

The spore print: white for the honey mushroom, rusty brown for the galerina. Galerina is also smaller and thinner-stemmed, with a smooth cap instead of dark central scales.

Do honey mushrooms and deadly galerina grow together?

They grow in clusters on the same kinds of rotting wood, in overlapping fall seasons. A cluster on a stump can be either one.

Can you tell galerina from honey mushrooms in a photo?

Not with confidence. Color and size vary with age and weather, and a photo cannot show the spore print. White spore dust on the lower caps of a cluster is a useful sign when it shows.
