Based on chemical features: We got two extended fragments of nrLSU that were a very good match to previous data considering there was a significant gap between them.

Hi Dario
If your interested join the Cville mycological society on facebook. There is a meeting this Sunday to discuss plans for 2017.

Thanks for sending this collection.

It’s great to know that we have another collection of albemarlensis from your site. There seems to be a tendency not to get complete sequences from your material. This might be due to the genetics themselves; but since we have examples of more complete sequences derived in some cases, it might be a problem with drying. I think it’s important to dry the material as soon as it is feasible (after photographs, notes, or other things you may wish to do) and not to dry the material at too high a temperature, In degrees F, try 105 to 115 as best your equipment will permit.

I am still fascinated by these species with the unusual initial characters of nrLSU.

This collection shows a distinct umbo. Did we discuss whether this umbo has unusually hard flesh (in comparison to other amanitas)?

It is quite curious that we have this collection of umbonate taxa in the Penetratrices that seem (small sample size WARNING) to have distinct geographic ranges. My guess is that this may not hold up in the long run. On the other hand, we’ve been finding penetratrix for several years; and all the collections still come from Connecticut (only).

Very best,


Thanks Dario,

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