Recognized by sight: another example of the “aprica-like” amanita. yellow-orange cap, exannulate, warts easily removed, close cup of a volva. the specimens here that grow in moss beds are always small. this is just up stream from Canyon sightings, but with poorer soils.

One more step on the road to understanding NA amanitas.

ITS DNA on GenBank

I submitted the ITS DNA sequence for this collection to GenBank under accession KR338837 (https://www.ncbi.nlm.nih.gov/nuccore/KR338837).

The voucher at the MICH herbarium can be found on mycoportal.org at:

this IS the exact fb that was DNA run, but it is representative of all of the distinctively macro-morph collections from both Huck and Canyon.

Here is what Rob had to say about it, after he did some analysis:

“DLVAM04 has strong support (84%) of being distinct from A. muscaria var. regalis and A.muscaria, but seems certain to be within the general muscaria clade. It doesn’t appear to be closely related to A. aprica but you could certainly search GenBank for aprica ITS sequences and add them in to see how far apart they are. I didn’t include the two top hits for DLVAM04 but looking at the accession #s on GenBank for the top 2 hits Rod Tulloss et al. call this "Amanita sp. sp-LG1045’’ and even have a taxon page for it at http://www.ncbi.nlm.nih.gov/... along with a publication “Evidence for strong inter- and intracontinental phylogeographic structure in Amanita muscaria, a wind-dispersed ectomycorrhizal basidiomycete.” If you can’t access the journal article let me know and I can send it to you. Definitely interesting."

So, these are similar to Rod’s Channel Isle amanitas, but not necessarily the exact same sp., definitely within the muscaria clade and definitely NOT aprica!

I am still wrapping my brain around all of these DNA concepts and what they actually mean, and how much user influence has on the outcomes. When one has to manipulate data to get it to “fit,” then human bias can be brought into the mix.

Still, DNA does seem to work very well to show general relatedness.

but this is an easy and unique species to recognize in hand, from the same area where the DNA determined fb was run.

to be in the muscaroid clade.

How cute!
