Observation 187796: Limacella “sp-L-CO01” Tulloss & Kuo cryptonom. temp.
When: 2014-11-08

Notes: Growing on a mossy bank near the bottom of a drainage into Jenkinson Lake reservoir, just above 3500 ft. elevation. Closest trees were Pacific yew and Douglas-fir, ponderosa pine also within rooting distance. Under the moss, lots of rotten wood and litter was built up, and the Limacella was growing directly next to pieces of well-rotten wood.
Three fruiting bodies were found, only one mature. Mature pileus had gluten dripping from the margin, and all were very slimy overall.
Pileus 7.3 cm, context very thin except for umbo, which rises 5 mm.
Stipe 11 cm x ~1 cm, tapered to 0.8 cm at apex. No annulus visible, but the upper stipe is free of slime.
Odor slightly farinaceous.
Update: on 12 November, we revisited the site. At least seven new fruiting bodies had emerged, most still very young. I collected the two oldest ones (new photographs) and plan to keep monitoring the site.

We got a pretty good “proposed barcode” sequence from your material. It seems to be a good match to DNA that was previously known to us from Colorado and Washington state. So now we have a triangle of localities for the species. It’s very interesting when data starts to paint a picture of distribution, etc.

Thank you very much for sharing your material with us.

We will eventually add your material here:

Very best,

Thanks Thea,

This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.
Thanks,
Naomi (working with RET)

Good evening, Thea.

I received your package today. Thanks you again for the material and your efforts. We’ll let you know as your material is processed. Hopefully, we get into a queue of sequencing as well as working it up morhologically.

Very best,

Rod

You’re very generous, Thea. Thank you.

I much appreciate the time and effort it takes to dry and send material.

Very best,

Rod

Collection is on its way to you tomorrow

Hi Rod,

Thanks for your interest. This is the first Limacella I’ve found in the Sierra Nevada, and it certainly is different from the very few others I’ve seen elsewhere in California.
The oldest specimen was the only mature one; I kept the larger unopened one moist for another day in hopes that it would open, but it didn’t quite get there. I’ll be checking the spot again in a few days, and will let you know if more have appeared.
All are dried now and I’m sending you half of each fruitbody. It’s all packed up and I’ll take it down to the post office tomorrow morning!

Good morning.

I don’t think I know this species. I have just had the great good fortune to obtain a number of DNA sequences from samples of Limacella. Dominantly, these sequences are from sect. Lubricae collected in the U.S. and Europe. I don’t think this species is represented in the data.

Also, I am unsure if I have ever seen this on MO before. I certainly haven’t seen it in fresh condition.

Would you be willing to share some dried specimens or halves of dried specimens that have caps in different stages of development? I would be very grateful for an opportunity to learn more about this species.

Very best,

Rod Tulloss
