Also good-sized mushroom. Though cap is pale grey-brown (see pic #1 of 2), underside and stem are white, white spores. This pic is the underside of the previous photo. This stem is also stringy and fibrous, tough.
Doesn't show it too clearly but it's coming from the dirt beneath this log.
What is it?? Is this the same as Mystery Mushroom #1, previous mushroom.
