I didn’t take any measurements at the time I had the mushroom in hand. However, I was able to locate the exact spot on the countertop where the picture had been taken and measure the length of hairline scratches on its surface. Hence, by solving a simple arithmetic problem I now arrive at the following measurements: ~3.2" tall; cap diameter = 2.5"; stipe diameter = ~0.25" near the apex, 0.28" at mid-section and 0.375" at the widest part of the bulb.

Lepiota cortinarius has a fibrillose partial veil…

like this example from Alaska last year:

This cool reddening lepiota looks to have a membranous veil…

Flammeotincta is a small, delicate Lepiota…what size was this one? Lepiota flammeotinctoides is a newly named species, similar but more robust, but it is unknown whether it occurs on the east coast. We need Else to be more bi-coastal!

Not every species that we collect has a good name, alas.

is an Eastern species which bruises orange and then darkens to dark brown. I do not think L. cortinarius bruises. I will post an old image of L. brunnescens.
It is a chameleon with the color of the fruitings depending on environmental conditions.

How about

That’s what I thought it was till I read in Phillip’s that L. flammeotincta is actually a Pacific Coast species…

looks like a good visual match. Else V. would probably have a better idea though.
