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.
Tephrocybe rancida has a long root did you see this.
Arrhenia (Omphalina) griseopallida has 10-16 lamellae far fewer than this find.
Did you take a spore print. I think it might be a much darker colour than you would expect for your suggestions and might possibly be an Inocybe.
I unfortunatly did not get a spore print, is this the only way of definitively fining out the variety
A spore print would only be one part of the puzzle. It might have told us the genus or at least ruled out some genus. There are often similar looking fruit-bodies with totally different coloured spores so knowing that would at least give us a starting point. Some species can be confidently identified to family from a photo. Some can even be identified to species but there are huge numbers that need not only a spore print but the size and shape of the spore the size and shape of the internal structure and even with all that it is not always easy.
