Observation 47804: Limacella “sp-L-CO01” Tulloss & Kuo crypt. temp.

Under fir. Smells like new potatoes (to my wife) or cucumber (to me). This is the first Limacella I’ve found. Looks like L. glischra in pictures, but I wouldn’t say the gluten is “bright reddish brown”, as in PNW Key Council description. Bright yellowish perhaps.

Rod, thanks again for the work on this collection. This was my first MO posting. Glad to see it’s been sequenced and identified.

We got a very good “proposed barcode” sequence from the material you sent.

Thanks for sending this interesting material, Sava.

The sequence we obtained was an almost perfect match for that of Limacellasp-L-CO01” which is a specimen from Colorado. It seems a little younger than your material and is notably paler and not so yellow.


Very best,

Rod Tulloss

Thanks Sava,

This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.

I apologize for answering only the first question this morning. I was in a rush at work and didn’t notice at first that you were asking more than just “true fir or Doug fir”.

(1) Stem color. I don’t believe that the handling changed the color much. The photo was taken immediately when I found the mushrooms. (The third one is still unpicked.) I actually didn’t notice that the stems were much different in color. Perhaps the little difference got emphasized by the use of flash?

(2) Stem length. I’m pretty sure that the entire stem of the younger mushroom is taken out and visible in the photo. I was using a knife. It looks like I cut a piece of the other stem, but I don’t believe that much of it was left in the ground.

(3) County. Klickitat, WA.

(4) Running into this lady again. I tried a week later but was not fortunate enough.

Thanks for your efforts,

It was a true fir (Abies).

When you reported that the mushroom was found under “fir,” what sort of fir was it? Was it “fir” (Abies)? Or “fir” as in “Doug Fir” (Pseudotsuga)?

There is distinct brown on the stem in one specimen. Could that have been caused by handling? Can you suggest an explanation for the fact that one stipe is yellow and the other is grown near the top?

I wonder how far down those stems went. If you run into this lady again, try to dig up her entire stem.

Oh, yes. I need the name for the county in which your collection was made.

[I’m making a website for this mushroom on the new new Amanitaceae site.]

Very best,


Dried Limacellas

Thanks for your comments. I actually tried to dry these Limacellas, but I’m afraid I left them in the desiccator for too long (overnight) so they look almost baked.

Too bad you have no dried specimen…

I don’t think that the cap really fits the original description of L. kauffmanii of which I prepared a summary:

20–75 mm wide, bay brown with a broad “raw sienna”” margin when young, with margin fading to antimony yellow, with surface below gluten somewhat streaked with stripes of lighter and darker yellowish brown, broadly ovoid at first, becoming obtuse, finally expanded with broad low umbo, even; context white or pallid, cottony, somewhat watery at first, becoming thin abruptly at half distance to margin; margin splitting during in situ drying; universal veil as thick, pale yellow gluten pile.

So it sounds like the young caps should be brown, and the older caps should be yellow only at the margin.

I am amazed at the number of different Limacellas that have appeared on MO and in my in-basket in recent years. I think there are a number of species that are poorly understood and need review, but their also seem to be undescribed species. Limacellas should be photographed with great care, described in writing, and dried well. What is missing from the mix right now, are well-documented collections…and type studies of Dr. H. V. Smith’s species as well as those of other N. Americans (not very many) who have named taxa that now are assigned to Limacella.

I’m very interested to see these photos.

Very best,
