Observation 147551: Amanita Pers.
When: 2013-10-05
Herbarium specimen reported

Notes: Jay Justice took it home with him. He had never seen this amanita before.
It started to rain as I took the in situ shot, so I didn’t photograph the volva.
Jay took more photos in the lab.

Recognized by sight: unique and very odd. strongly furrowed, very delicate cap, darker in center. median annulus lepiota-like, consisting of a shaggy ring. long slender stipe, base with short, thick, lobed volva.
Based on microscopic features: inamyloid spores.

Recognized by sight: the jury is still out, but that annulus is awfully lepiota-like.
Based on microscopic features: Jay or I need to look for stipe cystidia and/or gill trama. Hopefully at the AR NAMA this month, if not before.

Received your email note, Debbie. Sounds like an interesting trip to Missouri.

The microscopy of the stipe will reveal whether this is in the Amanitaceae.

There is at least one lepiotoid species with a saccate volva in the Caribbean region…

It was misplaced in Amanita when it was originally described: A. cystidiosa.

that’s exactly what I thought, too!

I did a sketch of the volva after it hit the dryer, and observed it while fresh.

the volva was similar to what we might see in an amidella, but it didn’t stain and the cap striations almost reached the cap center!

It was definitely some kind of an amanita, though, and not a lepiota.

odd bird, eh?

Jay thought that it might be one of the caesars, but that doesn’t really fit nicely, either. I did not pull off the volva to see if the stipe lacked a bulb, but a volva it did have.

Jay has both specimens.

The ring doesn’t seem amanita-like to me…

I hope Jay will make some shots of the stipe base available.
