Growing in a maintained lawn together with Panaeolus foenisecii. Frairly fragile light brown-redishbrown stipe. The light brown-greyish cap shape was mostly convex and a little more bell shaped and darker in younger specimen.

The specimens were a little dry since there was sun about. They grew mostly in partial shade.

Update 15-6-2021: Just took a look at the spores which seem ornamented. I guess this confirms Panaeolus olivaceus.

Update: Alan Rockefeller did DNA sequencing on these and found they match other Panaeolus olivaceus sequences in genbank.
