Deadly Galerina

Galerina marginata

Mushroom ID is a rule-out game. Every entry below describes something that looks similar — learn the differences before eating.

Honey MushroomArmillaria mellea

☠️ Deadly

Honey mushrooms have WHITE SPORE PRINTS, cream gills, and grow in big clusters from wood with a distinctive ring. Deadly galerinas have RUST-BROWN SPORE PRINTS, brown gills, and grow singly or in small groups ON THE SAME WOOD. Always take a spore print before eating honeys.

Liberty CapPsilocybe semilanceata

☠️ Deadly

Both are small brown-capped mushrooms, but deadly galerina grows on WOOD with a distinctive ring on the stem and RUST-BROWN spores. Liberty caps grow in GRASS with no ring and PURPLE-BLACK spores. Substrate + spore color separate them.

🌳 Host Trees & Plants

This species is found with or partners with the following hosts. Ectomycorrhizal hosts (green border) form a root-level partnership; ericoid / arbutoid shrubs (purple border) share the same mycorrhizal networks.

Identification Tips

• ✓Take a spore print on every small brown mushroom on wood — galerina is rust-brown
• ✓Bruise test: galerina does NOT stain blue; psilocybes do
• ✓Never eat Galerina regardless of preparation — amatoxins are not destroyed by cooking, drying, or fermentation
• ✓Same medical emergency as death cap — call Poison Control and head to ER
