these are quite bizarre fbs …

that look like they were dried out during development (not too shocking for San Diego). ;)

Perhaps the “annulus” that we see is just a manifestation of the environment, and not a true annulus at all?

At any rate, further study should tell the tale, and is now perfectly possible.

Yay, Jacob, for saving these!

I wonder if human lawns supply refugia.

I get quite a few collections of Limacella from watered lawns in Florida and East Texas and other places.

An MO post of Amanita thiersii the other day raised the same thoughts (again). Amanita thiersii must really love lawns. All that freshly cut grass supplied regularly during the human lawn-watering season in addition to whatever rain may fall. Oh, yummy! Cellulose!

Very best,


I’d really like to know what a younger specimen looks like.

Very often, Limacella collections are recognized when they are young (and don’t have spores); so it’s cool to have the hope of seeing limacellas with mature spores on them. On the other hand, this group is rather demanding in terms of ID from a picture. :) Can’t have my cake and eat it? Something like that?


Well, that’s cool.

Let’s see if this is really a Limacella. If so, it can’t be in the glioderma group (section Limacella) if that is really a membranous partial veil…which I think I see on several of the stems. All these caveats…oh, well. That’s the way it goes.

First the microscope to check for gluten-retaining hyphae on the cap and the stem and gill tissues, then the tweezers and little plastic centrifuge thingies.

Looking forward to this one, Jacob.

Very best,


I have specimens :)

I don’t report them till they’re pretty dry, in case something happens, but don’t worry about these :)

It’s been at least drizzling most of the time for the last few days! FINALLY

But I have several Limacella obses from the last few months without rain, they were in human-watered spots (like this one, I believe)

do you maybe actually have a specimen?

surely you knew that you had an oddity here.

with a red-brown cap and a farinaceous odor, it sure sounds like this one:


the slime veil is coating the stipe.

nice find, whatever it turns out to be. are you actually getting some rain down that way???

Oh, too bad about the lack of a specimen.

Please give me a little help on what the cap is like so I can get a grip on how you reached Limacella as a possibility.

If this is a Limacella, it could be a new one. The cap looks red-brown. The stem seems to be dry and to have a true partial veil. This would place the species (if a Limacella) in section Amanitellae. There are very few taxa of this section known from the entire world; we have two (according to some folks, one) of these species in North America. The known species (plural or singular) would have caps that appear white to cream to pinkish). It looks like the surface of the cap is red-brown in these photos. What did you see?

If you find this again, I’d really like to see some dried material.

Very best,
