I see how you got there now and it actually even looks promising, however Part G of the key is very confusing & headache inducing…

Is it possible you could add your additional gill close ups showing the pinkish gills to this observation? :)

How I ID’d Psathyrella corrugis…

To be honest, I’m never confident about identifying any fungus apart from a nice fresh Amanita muscaria, but the account of my ID of this example is recorded here: http://www.wildaboutbritain.co.uk/...
Best wishes,

How did you come up with Psathyrella corrugis?

I tried the key & I came up with P. magnispora, but I’m not entirely convinced of that…
