🌳 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.
Conifer Forest
Pinaceae (generic)
Ectomycorrhizal
Generic conifer habitat — pine, spruce, fir, hemlock, or Douglas-fir. Shown when the species is reported from conifers without a specific tree.
Small to medium orange-brown mushroom with a pointed cap and yellow-olive tones on the stem. Contains orellanine, a slow-acting kidney toxin with symptoms appearing 3 days to 3 weeks after ingestion — often too late for treatment.
Habitat
Coniferous forests, especially with spruce and pine, across Europe and North America. Late summer through fall.

Look-Alikes
Cantharellus spp. (Chanterelles)
CHOICE EDIBLE but multiple deaths have occurred from chanterelle-hunters accidentally picking orange Cortinarius. Chanterelles have FALSE gills (ridges); Cortinarius has TRUE gills and a rusty-brown spore print.
Gymnopilus spp.
Can also cause problems but less deadly. Bitter taste.
Identification Tips
- ✓NEVER eat orange gilled mushrooms without confirming a white or pale spore print (chanterelles/edibles) vs rust-brown (Cortinarius)
- ✓Feel for webbing (cortina) in young stage — a partial veil of fibers connects cap to stem
- ✓Orellanine symptoms can appear WEEKS after ingestion — kidney transplant is sometimes the only treatment
- ✓Call Poison Control at first suspicion even if you feel fine
