Based on past sightings (mostly since 2011; all years where recent records are few), not a forecast. Weather and place matter a lot, and a listing here says nothing about whether a mushroom is safe.

Usually recorded in October in this state:

โš  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.
