The Fungus Among Us The fungus forum is slow going; we don't have as many experts there as we do for the "flashier" plants. More's the pity, but South American fungi don't appear to have been as widely studied as North American and European ones, but I do know that there are at least 4 edible varieties because I purchase them at the farmer's markets. And you're preaching mushrooms to a photographer in close proximity to cloud- and rain-forests! Check these out... I have no idea whatsoever what they are. Except for #4 which are an edible from the Amazon jungle as well as a burn remedy, and which are called "Pig's Ears."
