Sorry, no photo. However, just found one, and it looks familiar, but I
can't place it.

Parasol shaped, white turning to brown, gills are white (which iirc, is a
bad sign if looking for edible), straight stem, no volval bag (good sign
for
not being poisonous), gills not attached to stem. Found on soil, autumn.

Google for parasol mushroom+images.
I would not like to advise you whether or not it is poisonous.
I often get parasol type mushrooms in my garden but I don't eat them, just
in case.
Apparently some of them are edible and delicious but I don't risk it.
