By porch in Whitinsville
On 11/8/10 found another that had a cap of 1 7/8". Got a good spore print. It was cinnamon brown. Decided that it might be an Agrocybe growing on buried wood. This spot is within 10' of the woods. It keyed out as Agrocybe firma through the Mushroom Expert site.
As growing in splash stones under edge of
roof. Cap 1 3/8", stem 1" long and 3/16" thick. No noticeable odor.
Spore print was cinnamon brown.
measured 9.6 x 4.8 microns.
