Definitely in the La. cupresseus ballpark, but…

The reddening reaction is a tricky one. In most cases, particularly in
humid weather (a conjecture of mine) it tends to turn quickly to
fuscous. I have had a lot of exposure to these under Cypress.

But in dry weather I have seen collections from the same patch that
hold the carmine red for a long time and it even stays that way in the
dry material. Note how the color is less red towards the cap
trama. Anyway, the microscopy was the same as above.

Of course, I wouldn’t dare to go to Else with a Lepiota question
without having done the microscopy first, or she’ll beat me up and
kick me out.

Have fun,

Microscopic characters? I’m sure they are there…but i didn’t look for them!

don’t know what happened to that fruit body, either….unless Christian or some other taxonomically obsessed (and that’s a good thing!) individual snagged it from the Fair.

probably Leucoagaricus cupresseus

i agree with Josh – this does not look like L. roseifolia, as it is too big, too fleshy, and not the right colours, and it lacks the intense reddening reactions. Microscopical characters?

Really cool.

I wouldn’t be as quick to put that name on it! But then what we have called roseifolia up here i guess is quite different from the true species! There are some cool and poorly known things in the pilatianus group where this may belong. I hope you saved some for Else?
