I need help with this one – any suggestions?

You were on the right track from the start then (species around grangei are ruled out because of the spore shape). I can’t say I have any experience at all from Lepiota species. Well, except for the more common and less demanding ones that can be found further north, then.

Yes, either L. forquignonii

or the cluster around L.grangei which is more southern … I found it in Italy and Czech Republic. L. forquignonii is known to grow on sandy soil but I am not familiar with var.coniferarum.

How about

Lepiota forquignonii – var. coniferarum, with darker umbo and a bit larger spores…
Gerhard, is that why you asked if it vas green..?

So now at least we can say

it belongs to the section Ovisporae and here it must come close to the vicinity of Lepiota felina I suppose altho the scales are not felina-like.

I have a dried specimen

Will add some info when I have managed to check it more (made some notes from fresh material, but it’s gone with the wind..)

Then it is difficult. Any micro details?

Not greenish

Just very dark brown (the colours look right on my screen). It’s fairly large for a Lepiota, the largest cap 6-7 cm. They were very torn by snails and I couldn’t get a whole fruitbody out of the grass. It’s possibly a brownish ring at the lower part of the stem, and I was wondering if it could be Lepiota ignivolvata? Hmm.. that is supposed to grow in Fagus forests? This was under Pinus (along with Dermoloma and waxcaps, so it could just as well had been an open grassland, I think).

I didn’t notice any particular smell from it. But it was cold, windy and raining that day :-(

Is it greenish on the cap?
