This map shows locations of death cap mushroom sightings and death cap mushroom poisonings within the province of British Columbia and western Washington.
The death cap mushroom (Amanita phalloides) sightings are based on reports collected by the University of British Columbia, the BC Ministry of Forestry, Lands and Natural Resources, the Forest Pathology Herbarium at the Pacific Forestry Centre, and other regional herbaria contributing to the Consortium of Pacific Northwest Herbaria. Data is reviewed by mycology experts annually. Reported sightings include GPS coordinates; for display purposes, multiple sightings within 30m of each other are represented with a single icon in the map.

- Death cap mushroom sightings and poisonings are verified by professionals by examining photos and specimens of mushrooms. Mushroom specimens may be submitted for visual examination, to determine toxin and DNA profiles. When evidence of a death cap mushroom sighting is reviewed, and evidence confirms the mushroom found is
Amanita phalloides (a death cap mushroom), the sample is vouchered.
- Most death cap mushroom sightings are reported by the public: mycology enthusiasts, citizen scientists, mushroom club members and volunteers. To report a sighting, use the BC government report
