Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Why do you think it is acuminatus rather than foenisecii or fimicola?
The description of the others says stipe smoothsilky/smooth satiny whereas acuminatus is light-grey pruinose on a dark background. This seems to fit better. Of course the spores of foenisecii are warty and firmicola has smaller spores. Unfortunatley we cannot see them ;)
From the photo alone as with lots of these it is only a best guess so it could be one of the others.
I wasn't aware of that feature of the stipe. I've assumed they can only be ID'd under a microscope, but that's a useful distinction in the field.
