Not to sound spammy, but my better half forages for many mushrooms (oyster, hen of the woods, morels, chicken of the woods, coral, puffball, a ton that don't have fun mainstream names for me to remember ). He was previously selling to NYC restaurants but we've since relocated out of that market and have yet have more access to prime forest/woodland environments. What we cannot eat/use ourselves, we are attempting to sell online.
I'd like to propose if anyone is interested here, get in touch. He's a regular on mushroom specific forums online, I'll try and get him over here to participate too. : )
Or, if anyone has suggestions to venues to sell, fire away. I'm hesitant to suggest the farmer's market route because he doesn't have any sort of certification, license, insurance... and people up here honestly seem terrified of poisonous mushrooms.
