Huh - actually I think you technically need a permit to forage in the NY state parks as well - although I'm not sure the penalties for failing to get one. Nor am I sure if the rationale is the same.

"Up to a gallon?" So strange - how does one measure a gallon of fresh mushrooms? They must have commercial licenses too I suppose with larger limits.

I guess I'll check in san francisco as well... although I don't forage for food generally - just a few representative samples of a given species to do a write up on usually.
