Recognized by sight: This soft Polyporus species almost always fruits from roots or buried wood. If you dig down you can find the point of attachment. I often put this species on my lab exam as a “trick” question, to see if the students can tell the differnce between this and a bolete. (The easiest way to distinguish is that the pores of Polyporus never peel from the flesh of the cap.) There is also the possibiilty that this is Polyporus melanopus, but that is rarer in my experience and is distinguished by microscopic characteristics.

It was soft and rubbery. This mushroom was growing in a little flat spot where two gullies come together. The soil was very rich and deep there, lots of composting sticks and leaves. The mushroom might have been attached to a piece of buried wood.

Was this tough, woody or leathery? If so, it’s one of the stalked polypores. Otherwise a rather oddball bolete.
