Observation 15918: Pluteus americanus (P. Banerjee & Sundb.) Justo, E.F. Malysheva & Minnis
When: 2008-12-05
No herbarium specimen

Notes: Free gill attachment.

I found this mushroom while digging for another, much larger mushroom. It seemed like it just dropped out of the sky but it was probably growing on a twig on the ground.

Now you removed the ones I thought was Pluteus cyanopus, so I’ll have to remove that suggestion as well.
Eh.. I didn’t manage to do that.

Two species

Dan and Debbie are correct – The first pic is the mysterious pluteus, the rest of them were a Nolanea I was photographing in the parking lot. I removed the incorrect images. I only got one decent shot of the pluteus, but I did recently find the sample so I can do some microscopy.

Two different kinds

I agree, there appears to be two different kinds of Pluteus here. The mushroom in the first photo looks to be psilocybin active; the other does not. Did both specimens have the characteristic smell?

two different species of mushroom?

I don’t believe that the top mushroom, with gray/blue cap, pink gills and thick blue stipe is the same as the slender, striate, brown-capped thin white stipe shrooms pictured below.

maybe we’re both right, and you just need two sightings?

I’ve been calling this the year of the unknown Pluteus, I’ve got 3-4 I’ve got to scope out, and try and get a name on them. I need to get a good source for Pluteus, does any one have a favorite?

lovely little pluteus!
