Good evening, Christine.

After a week’s work on a large shipment of DNA sequences. I’m convinced that this is Limacella glischra. Thanks very much.

Go here and see your the impact of the contributions you and others on MO have made to this particular piece of research:


Very best,


We have had a rough look at DNA extracted from the material you sent us, Christine.

Thank you once again for this little gooey learning opportunity.

What we can see so far is this falls into the largest single cluster (probably representing a single species) of Limacella collections that were sampled. We are going through all our data and will have more to say later. From the collections that have the proposed “barcode” gene (nrITS) in common with this mushroom (i.e., are probably the same species) the range extends from Tennessee to Indiana south to Missouri. This is probably very incomplete.

On the other hand, for a Limacella this guy seems to be collected more than most; so it would be interesting to see if we can get material from other areas.

Not even guessing at names yet.

Very best,


Thank you, Christine.

Your packet arrived some time ago; and I just got to accessioning it in the herbarium. I look forward to studying it. More when I know more.

Very best,


So far as I know, yes.

The developing cap of Limacella is said to develop vertically oriented hyphae that turn into gluten (slime) and then a second set of hyphae grow into the slime. Apparently this second and finer (thinner) set of hyphae hold the gluten in place.

This is covered in the “About” pages on the WAO website…here:


Very best,


specialized hyphae

These specialized cells are only present in the genus Limacella? I was able to obtain a spore print, so I have looked at the spores and I was able to collect specimens that were are mature enough to produce spores. Thanks for the info.

The shots of the gluten-supporting hyphae are really nice.[edit]

This isn’t a pileipellis. These are specialized hyphae that hold the gluten in place on the cap of a Limacella. At present, I think they are most analogous to the volval tissues in Amanita. I think these are the first images of this tissue on MO. Congratulations.

I’d be very pleased to have some material that bears spores. Thank you. I have never seen this species so CLOSE. I’ve seen what I thought was glischra fresh, but did not have the opportunity to see them under the magnification you have achieved with a modern digital camera.

Very best,

More fruitbodies found. Thanks for your interest in my observation. I think I can go ahead and let you have these.

I would very much like to borrow this specimen.
