Limacella is so interesting…and so neglected in North America…

I really appreciate your collections.

We are also very fortunate that Dr. Geml is willing to take on the sequencing task in his lab in Leiden and that Dr. Nagy (Szeged Univ., Hungary) asked me to participate in the Agaricales Diverisification Project (“aDiv” or “3,000 agarics”) by designing the sampling of Amanita and Limacella. That was a good motivation to go after as much of Limacella as could be managed.

You can begin to see the effect/results by the appearance, disappearance, and combination of temporary codes on the WAO website:

This mutability can also be traced in the site news over the last year or two:

Thanks, again.

Very best,

Thanks so much, Rod

for all the new information on these observations.

An addition….

The material from the present observation and the material of MO #156614, as might be expected since, they were collected from the same site, yielded exactly the same “proposed fungal barcode” sequence. This sequence is very close to that of Limacellasp-CMP0152” from SE Arizona and central Mexico. We are awaiting sequences of at least one more gene from Drew’s two collections.

Very best,

Rod

Thanks to Tatiana Semenova and Jozsef Geml, we now have genetic data to utilize in clarifiying the picture slightly. We also have genetic data from this particular collection, which excludes inclusion of the collection in L. subillinita.

With the new data in hand, Limacella subillinita has known distribution from Florida around the Gulf of Mexico and the Caribbean Sea to to the state of Chiapas, Mexico and, thence, to Panama. There is no evidence for its existence in North America west of the plains or, indeed, at any significant distance from the Gulf of Mexico. The collection Tulloss 8-31-94-E is assignable to the Chiricahua Mycoflora Project entity called Limacellasp-CMP1052.” The Florida collection made by the late Robert Williams (10.×.1995) is clearly assignable to Limacella subillinita on genetic and morphological grounds.

Therefore, the set of names of relevance to this observation has shrunken to four:

http://www.amanitaceae.org?Limacella%20illinita%20var.%20argillacea/...
http://www.amanitaceae.org?Limacella%20sp-CMP0152 http://www.amanitaceae.org?Limacella%20illinita%20var.%20rubescens/...
http://www.amanitaceae.org?Limacella%20illinita%20sensu%20H.%20V.%20Smith/...

Of the remaining, L. illinita var. rubescens has red staining slime, which is not visible in Drew’s photographs.

We are now left with the question of what Dr. Helen Smith meant by her usage of illinita and by her variety illinita var. argillacea. Material that may be relevant has been located in herbaria. This material in question was collected in California and Oregon by Drs. Helen and Alexander Smith more or less 70 years ago. The plan is to borrow this material with permission to sequence it. There is some chance of being able to extract DNA using “forensic” methods.

Thanks, Drew, for this interesting material.

Very best,

Rod Tulloss

Two collections from the same site would be useful. EDITED FOR MISCOUNT

Thank you for your willingness to send material.

Also, thank you for pointing out the site-is-the-same situation.

I went back to count the taxa that have been named at an infraspecific level in L. illinita or were considered close to illinita or called illinita by authors and collectors: I get a current count of [BEGIN EDIT} five to seven [END EDIT]in North America, excluding the European illinita. There may be some duplication among the names and temporary codes. Here’s what there is with regard to WAO links:

http://www.amanitaceae.org?Limacella%20illinita%20var.%20argillacea/...
http://www.amanitaceae.org?Limacella%20illinita%20var.%20rubescens/...
http://www.amanitaceae.org?Limacella%20subillinita
http://www.amanitaceae.org?Limacella%20illinita%20sensu%20H.%20V.%20Smith/...
http://www.amanitaceae.org?Limacella%20sp-CMP0152
http://www.amanitaceae.org?Limacella%20sp-Tulloss-8-31-94-E
http://www.amanitaceae.org?Limacella%20sp-Williams-10-x-1995

The first two temporary codes could be the same thing.

The last temporary code could be subillinita.

Very best,

Rod

I would be glad to send this collection, though I’m wondering if you noticed that observation #156614 (which I sent to you) is from the same location. Let me know if you still want this one.

Thanks for your comments on the taxonomy.

Best,

Drew

Thanks. I should point out that though the westside and eastside weather patterns in WA often overlap, it is not always the case. The fungi have their differences as well. Westside Cascades as opposed to westside Rockies. We have had rains that began the middle of August – much earlier than usual. Haven’t had much in a couple of weeks though. Haven’t followed the westside rain situation too closely.

Hello, Drew.

Would you be willing to send me a part of your collection from this observation?

I don’t think that it is illinita in the strict sense of the Friesian name. However, it might be the North American Limacella illinita var. argillaceae H. V. Smith which was described from the U.S. West Coast (south of you in California). I am not sure how many taxa are called illinita in North America, but I think that at least three species are treated under that name.

A very pretty set of specimens.

Very best,

Rod Tulloss

nice!

maybe these will stick around for the NAMA foray in October! I have never found this genus.

are you getting good rain up that way?
