Fool's Conecap Group?

Growing at the side of a path, woodchips were around but it seemed to be growing from soil among grass with a couple of other mushrooms, here's one of the others: http://www.projectnoah.org/spottings/970346007 . smell was like a lot of mushrooms, apricoty, taste not distinctive. About 8cm tall and 3-3.5cm across the cap, I had previously scratched the stipe to check for blue discolouration (there wasn't any) and might have moved the annulus/ring down to about 1/3 of the way up the stipe where I found it later (see the remnant on first photo 1/3 of the way down the stem) and it appeared attached at this point. One side of the annulus looked like it had strong striations (6th photo). The stem was tough and pliable which makes me think it's not a psathyrella? Cap was hygrophanous and possibly has striations or radial wrinkles/striations at the edge. After some research I thought possibly Stropharia coronilla but S. coronilla has adnate-ish gills, and in older fruitbodies the gills turn purple/blackish. A second fruitbody had a rusty brown to darker brown spore sprint. Other species I thought about were Psilocybe cyanescens (before I had scratched the stem to check for blueing), Galerina marginatum (I ruled this out because of substrate, smell and gill attachment). At the moment I think it is probably a Conocybe of which there are severel similar species that can only be distinguished with certainty using a microscope (or, presumably, a DNA sequencer). Conocybe rugosa and C. filaris belong to the group I'm not sure on other species that belong to the group
