Good morning, Irene.

In the last week we obtained a small flood of DNA data concerning Limacella from Jozsef Geml and Tatiana Semenova in Leiden. The material of this observation contributed our obtaining a good set of data for L. guttata. I am very grateful for your contribution of the collection associated with this observation.

Very best,

Rod

This collection is one of those that Dr. Jozsef Geml and his students are using to extract DNA for a history of the genetic development of Agarics (the “aDiv” or “3000 agarics” project). Yesterday, I got the raw output from Dr. Geml that appears to yield an ITS (proposed barcode) sequence from this collection.

Dr. Geml will be trying for two additional genes to contributed to the aDiv project. Hopefully, we can get them from your material.

Again, I want to express my gratitude for your having sent this material to me.

Very best,

Rod

Thank you, Irene.

Dried material of this specimen has arrived in Roosevelt, NJ.

I recommend Andreas’ article that he mentions (below). He treats, L. guttata as the type of a small and unique section of Limacella…and this makes a lot of sense to me as someone just a few years into trying to understand the limacellas of the Americas.

By the way, Irene’s collections just received and other limacellas contributed to my research through MO will appear in greater and greater detail on the new Amanita Studies web site (under construction) that will cover all the taxa of the Amanitaceae. We’re still several months away from a first release of the site.

That makes it rather easy then :-) I don’t have access to your paper, but if I run across a mysterious ringless species, I’ll probably show it here and hope for help.

hello Irene, in Europe there is only one species of Limacella with a membranaceous ring. All others have a velar zone/girdles only or none at all.
I published a paper dealing with the Limacella species with non-slimy stipe: GMINDER, A. (1994a) – Die trockenstieligen Arten der Gattung Limacella in Europa. Zeitschrift für Mykologie 60(2): 377-398. May be you have that journal in reach, there is a key in which still is useful I think.

Thanks Andreas

for having a look at this obs. I also suspected L. guttata but wasn’t sure.
I do have a collection, but I find it difficult to tell Limacellas apart by micro characters (and I don’t know what other species there might be).
