This is one of the Amanitas growing in mulch , from this photograph. I was confused, since Amanitas are all mycorrhizal, growing in symbiosis with tree roots. Most of the time you see mushrooms in mulch, they are produced by a fungus that is consuming the mulch. I consulted the experts, one of whom wanted to know if the mushroom had a volva (the remains of the veil that encapsulated the mushroom when it was young) on the base. I dug it out and took this picture. It has a volva, and also has rhizomorphs: threads of rootlike mycelium coming from the base. Amanita rubescens, or a close relative, was the consensus.
