There were other types of mushrooms near the Oyster bed. It is difficult for me to convey their size so hopefully by comparing them to the surrounding leaves, pine needles and moss fronds you can get an idea.
These little guys are probably three to four times the size of the head of a pin.
Maybe about the size of a BB for a BB gun.
These flies enjoy roosting on the mushrooms and don't seem to mind my presence.
It is as if they are on a mushroom high and oblivious to everything around them.
He kind of looks to be sitting on a snowy slope with evergreens hanging low.
