a bed of King Stropharia to me. This is exactly the environment one would expect to find Stropharia rugosa-annulata: recently chipped coarse wood, probably less than 4 inches deep (deeper material gets too hot). Should you care to do so, you should find more ropey strands of rhizomorphs throughout the wood chips. The very large size of the fungi also points to S. r-a. Only very young specimens should be examined for edibility, since they are prone to sclerid fly larvae (maggots) which can riddle even young button mushrooms within days, and the entire sclerid fly lifespan takes only 3 days.

Ok, yeah, I can see that — I went out and inspected the base of the stem very closely, and there are a few small distinct ones.

You can see the rhizomorphs pretty well in your third shot, at the upper left hand corner of the photo.

This could be it … but it does not have any root-like membranes coming out of the bottom such as is shown on this page: http://www.messiah.edu/...
I wish I had noticed these before today when they weren’t already all the way open!!
