I am obsessing about ID ing this mushroom. I live in the subtropics (South Florida) but use leaves for mulching and horse manure mixed with mulch and often get mushrooms in the year. This one had a red cap with the edges of the cap being lighter. The color fading after a few days and looking more like cream/speckled at the end. The stem was cream.light brown color straight. The spore print was a distinct blue/royal blue/navy blue and when it got older brown. The bottom of the cap was clearly spongy (no gills). I forgot to check bruising. The cap had a little nick like an insect had a taste and perhaps stopped tasting:-)
