Mark Bower found this unusual mushroom in the woods above Bull Creek. It is unusual in that its stem isn't centered in the cap but more off to the side. He identified it as Boletinellus merulioides, a bolete fungus that is found around ash trees this time of year. Most mushrooms associated with particular trees are mycorrhizal, living in symbiosis with tree roots. They absorb minerals from the soil and exchange them with the tree for nutrition the tree produces by photosynthesis. Not so with B. meruliodes, which makes its living off of aphids!
