Observation 55095: Limacella
When: 2010-10-09
Herbarium specimen reported

Notes: This Limacella fruits every year but in small numbers in the relic dune pine forest near Akademgorodok. I always thought they fall into L. illinita sensu lato but the s.l. issue is bothering me now that I’ve seen the difference between it and the mushroom from this observation:

I agree. “Interesting.”

In the U.S. we have a rubescent “variety” (that I’ve not seen). We have at least two non-rubescent taxa in North America that are called either “limacella” or “limacella var. argillacea” (type of the latter is from California). One of the two taxa I think I can distinguish has been sent to me repeatedly from Florida (see


); the other I know from the Chiricahua Mtns in SE Arizona and from the state of Tlaxcala (also montane habitat) in the central, neovolcanic zone of Mexico (see


). One should also be aware of a poorly known Mexican species:


What I learn about these taxa will end up on the new website as information is accumulated. I have several collections in the herbarium that have not yet been examined microscopically in any way; and so some enrichment of data is possible….when time permits.

I’m afraid that the North American literature on Limacella is rather dated. I’m trying to get as much data together as I can, and put it on the new website.

I suppose we can all try to clear our local fogs. Luckily, communication via the web may be useful in getting a better command of the situation. It seems to me that Irene is most likely to find material that would be of the sort that Fries saw and, hence, is most likely to see the variation present in what one could call the original Friesian concept.

Just because the same name has been used around the world does not necessarily imply that we are not dealing with some local endemism in some places. The puzzle is interesting. At least the puzzle is under discussion…although we may not know enough yet to exactly describe the puzzle. I hope Andreas Gminder will also give his views.

Very best,

Limacella illinita sensu lato seems like a suitable approach.
I’m sure Ret would be interested in collections of both forms.
At least two varieties are described (one american), there could be more.
