To me, this was perhaps the most interesting mushroom of the weekend. Cap color is not what one would associate with xerampalina types. But the following were observed: fishy odor, brown staining on gills, sulcate cap margin (which I believe rules out R. compacta), yellow spore print, Spiny or warty spores (I'm not really sure what the difference is; photo did not capture this). Found growing on a lawn beneath Norway Spruce.
