Macrocystidia Cucumis?

[KeenTeen17]

Is this cucumber cap?
This was initially IDed as psathyrella pseudogracilis but I can't find that in my Philips so I thought it look like macrocystidia cucumis.

Unfortunately not mate, this is a Psathyrella. Don't ask for species though

Macrocystidia cucumis is darker than this, and it absolutely stinks of cod liver oil. Seriosuly, it's so potent that you'll know if you find it. The species has a slender stipe, not dissimilar to Psathyrella in structure, but different in the fact that the further down the stipe you go, the colour gets darker until at the base it appears black- often with a velvet-like appearance.
