From my notes:
Located on wood chips, latte/light brown in color
5 mm tall from base to top of cap, caps are 5-7 mm across
thick, woody stems
tan, unattached gills
Light brown/tan spore print
(These notes are going to have to become far more detailed if I'm ever going to have success in identification!)
To make a "spore print" you separate the cap from the stem. Place the cap, gill side down, on a white sheet of paper. Cover with an over-turned drinking glass so that it's not disturbed. After several hours, when you remove the glass and the mushroom cap, you will be left with a print of spores on the paper. Spores come in all different colors, from white to orange to to pink to black, and the prints can be really quite beautiful.
My guess is that it's something in the Pluteus genus.
