This is the wrong habitat for Panaeolus. Many Psathyrella have mottled (inaequihymeniiferous) gills too. The microscopy strongly points to Psathyrella due to the elongate ellipsoid spores and the shape of the cystidia.
edit: It’s spelled https://en.wiktionary.org/wiki/inaequihymeniiferous

Thanks for the correction. I was not sure what to write, Panaeolus or Psathyrella; the distinction between the two is not always clear to me. In this example, I was not sure whether one could call these gills mottled or not.
Essential comment—-greatly appreciated.
