What synchronicity, as it turns out I was in the forest today and found this trinity of mushrooms. Now I don't even need to search through my archives to find a group of three mushies growing together. I believe this may be an evil trinity though as its common name is Devil's Urn with the latin name Urnula Craterium. I read these are technically edible but are not very tasty and have a tough texture. But if you are trying to survive in the forest without food they could come in handy.
