Caps on stems; pores below caps [boletes & stemmed polypores]
The fungi in this group produce fruitbodies with pores on the underside of the cap. Mostly the pores are roughly circular but in some species they are elongated. In some species the pores measure a millimetre or more in diameter but in others they are almost invisible to the naked eye and you may need a magnifying glass or hand lens to confirm their presence.

Just clarifying one point. This sighting is not the way they normally start out. It shows the final, mature state that has developed in an unsual way. Normally you'd see some stem& cap growth.

Well, if this conversation hadn't happened I probably wouldn't have understood that's how they start out!

Well that was dumb of me to miss the bit of this in the other sighting you put up!
