⚠ Never eat a wild mushroom based on this site. We show where fungi have been recorded, nothing more. We never say any mushroom is edible or safe, and you shouldn't decide that from any website, app or photo. Many deadly mushrooms look like harmless ones. If someone may have eaten a wild mushroom, call Poison Control at 1-800-222-1222 right away.

The 10 most recent dated records in this county, newest first. Data as of October 26, 2026. Records can take weeks or more to reach GBIF, so the newest finds may not show yet. Places are given only as a public park or forest (from the USGS Protected Areas Database) or the nearest town, and the numbered circles on the map cover a general area, not an exact spot.
