Looking at it again you could be right because C geotropa normally has an umbo bump in the middle of the cap and these don't appear to. I jumped to this conclusion because I've seen tons of funnel caps recently. Would be able to tell in real life
I'm not a great one for eating things that I'm not absolutely definitely sure of - and I''m very aware of my own identification limitations - so this is generally things that can't really be mistaken for anything else - like chicken of the woods, chanterelles (and black trumpets), and ceps. Clitocybes I'm too unsure of to try. There's just so many species.
I could of course be wrong () and your first hunch could be right, especially as it's exactly the right time of year, but a) they don't look very tall for the size of the caps b) it's unusual IME for Troopers to cluster like that - the trooping tendency is very strong, c) I can't see an umbo either (although it can disappear when they get big enough) and d) something about what twitchers call 'the jizz' (yeah, I know) from above suggests Lactarius to me - can I see a faint concentric pattern??
Anyway all these questions could be put to bed by including photos of the stem and gills - anyone hoping for online ID help please note!
