Not same specimens

The 3 observations linked to each other here are from different fruiting bodies of the same organism, popping up at different times. (a fortiori the same species.)

Both sections have dry stems. I wasn’t convinced in these pictures that I was seeing a membranous partial veil.

I’m wondering what molecular work will have to say about the Limacella sections. In Amanita the morphologically defined sections are surviving, with the movement of a species here and there between sections…so far.

We need some way of talking about unnamed taxa, and the sections have provided a workable option in the Amanitaceae.

Very best,


Sect. Limacella or Amanitellae?

Pretty simple, smallish pine tree in artificially watered grass in the middle of campus. There is coastal fog here. Very comfortable mediterranean climate.

Largest cap dia. 2.5 – 3cm.

Very cool

Maybe it is the stage of growth, but I don’t recognize this one as something that I’ve seen previously.

It is really fascinating to me the number of potential Limacella species that come out of some parts of the U.S. Was this mushroom located in a place with coastal fog? Knowing more about the ecology would be very interesting to me. Do you have notes on dimensions of the fruiting bodies?

If you can spare any dried material for me to study, I have a small open window for sending Limacellas out for sequencing. Sequences are going to be really useful in sorting the number of unnamed limacellas in North America.

Very best,
