Why not P. fragilissima?

Compare with observation 87767, or how about another one of the species in subgenus Candolleana section Fragilissimae assuming there is no pleurocystidia and “Spores (9-)10-12 μ or more long”?

I don’t think there is enough information in this observation yet to say this is P. longipes.

Edit: One way you might possibly distinguish the two macroscopically is the pileus texture, P. fragilissima will have “at first covered
by snow-white evanescent floccose-fibrillose superficial scales, soon glabrous” and P. longipes, “fibrillose becoming glabrous”. As for other species in the group, I’m not sure yet.
