when I broke it open, the flesh just above the gills as well as the gills appeared to be a sickly greenish colour. The surface of the cap and the flesh just below the surface remained the off white/beige colour. I may have a picture of that, if I do, I will add it.

I, unfortunately didn’t have anything with me to collect specimens, so I won’t have a spore print.

There was an odour, but I can’t place a name to it. It wasn’t radishy/fishy/sweet or anything. It was noticable but not strong.

It’s difficult to tell from the picture but it looks somewhat like a Stropharia aeruginosa or Stropharia caerulea. Was it viscid and is the coloring bluish or blue-green? A spore print would be very useful.
