We have recieved this material and it has been accessioned to Rod’s herbarium. We are scheduling it for DNA sequencing.

Interesting. Both of these mushrooms were found in the same proximity, about 4 feet apart.

Here is the name I couldn’t remember and a link.

This mushroom has only been found a few times; however, it has always been found with with volval sac deep in wet soil and in a state of slimy decay.

I am not saying that “sp-Litten_L-714” is what you have. I don’t think that at all. This is just my example of a relatively deeply inserted species that “sacrifices its stipe base.”

Very best,


The damp soil may also weaken the stem.

I have seen several species in section Vaginatae that, once the cap is above ground, are willing to “discard” the stem base. They simply let it decay…possibly this is because they restrict antibiotic compounds to the upper stem and cap in such a way that the cap can be kept properly oriented while any “excess” stem is simply sacrificed. Excuse me for the anthropomorphic metaphors. I know that mushroom doesn’t make decisions. I’m tryint to describe a possible evolutionary outcome that reduces expenditure of energy on maintaining an entire mushroom once spore liberation is underway with the gills at the “right” angle.

I have a particular amanita in mind…I’ll post it when I remember its name.

Very best,


Yes, was having trouble with damp soil clumped up around the base.

I think I’m guessing in the right direction.

You may need an extraction tool that can reach a greater depth…perhaps a significantly deeper depth.
