Nature note: wild mushrooms

The two lovely mushrooms that have appeared in grass lawn downstairs of my house last week.

One side of the big mushroom was a bit dry up already, wondering why they came out of nowhere in such a open field without any shade...Maybe because of the a few days rainfall?

Is it any different from what we bought in super market? :) Do you recognize these juicy lovely white mushroom, just cook them for dinner. :).

...and this two photos are captured somewhere near my office, same kind of open field...

I thought mushrooms are growing on the dead wood in those forest, jungle area? A surprise for me from the nature. More nature note here at  Rambling Woods.
