Common Name: Reddening Lepiota
Synonyms: Lepiota americana
Location: Logs, more commonly woodchips
Spore Color: White
Gill Color: White
This mushroom can be found growing on logs, but it is more commonly found growing in woodchips or the ground. First look for white gills that are free from the stem, and a ring on the stem. This should lead you towards Amanita or Lepiota. This mushroom can grow from wood directly, so that may lead you away from those species (as they typically grow on the ground), but this is in the Lepiota family.
The cap should have red scales, that may fade with age. Rubbing the stem should cause it to bruise yellow very quickly, with the bruising eventually turning red over time. The cap, gills, stem, and ring can all bruise red. This mushroom often has an enlarged, swollen base, but not always.
Said to be a good edible.
Chlorophyllum molybdites has green gills and spores at maturity. Chlorophyllum rhacodes has larger brownish scales on the cap and stains orangish on the base when cut. Macrolepiota procera has brown scales on the cap and does not bruise.
Same mushrooms the day after the first picture.

Cell phone shot. This mushroom was found growing directly from a cut log. Red scales have faded.
Notice the yellow bruising on the stem.
The yellow bruising eventually turns a dark red.
This mushroom hiked in a backpack for an hour on trails before this picture was taken.
