Notes: Found growing on a pile of leaves, mulched, after a heavy snowstorm/ice/heavy rains, under tall near old-growth Douglas fir. Growing at the I-5 northbound rest area near Wilsonville, Oregon.

Habitat suggests this may be a Lepista, but does not appear to be L. nuda (which I have also found after frosts and freezes – it appears to have an anti-freeze compound in it).
