the smaller North American species of sect. Amidella. In the last picture showing the top of the cap toward the lower edge of the cap, there are fainltly pinkish very thin patches of the inner surface of a typical Amidella multilayered volva. I will bet that by now those thin, faintly pink patches have darkened toward a brownish red.

I think the above is further evidence that we are looking at a species of section Amidella.

Very best,

(see righthand side of top photo) and a whitish cap with a patch of membranous volva on it. Is very likely to indicate a species of sect. Amidella. The next thing to check is to see if the base of the stem has a bulb or not. In sect. Amidella, the volval sac is very thick and suggests a bulb, but there is not bulb present the stipe simply expands evenly as you descend it (or narrows evenly as you ascend it). My guess is that this is, indeed, a member of section Amidella.

And Eva’s obs. 139532. They look similar to me.

Maybe we can get R.E.T.’s opinion here.

any nearby trees, Eva?

Gills are notched, serrated. I thought that was only in Lentinula, but obviously this isn’t growing on wood or any kind of coarse woody debris nearby.

Amanita comes to mind, with the enlarged base. So does Tricholoma.
