Observation 177572: Amanita pachysperma G.F. Atk.
When: 2014-09-10

Notes: The stipe bases were buried, which made extracting the volva difficult at best. I managed to get one mostly intact.

Color in photos is true, gray centered caps fading toward the margins. No brown overtones.

Specimens are being preserved for study.

And thank you for taking the time to post a comment for every collection I submit.

These came from a corner of my brother’s property that I remember well. Eventually, I’ll post a few additional details about the habitat.

Thanks Dave,

This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.

I compared the spores…

seen in this obs with some spores I believe to be A. crenulata spores. Assuming the observed crenulata spores have max length about 9 mu, then comparison with the spores in this post (177572) and a little arithmetic produce an estimate of about 15-16 mu for the max spore length observed here.

Eventually, I’ll have a micrometer mounted onto my scope.

Thank you, David.

We’re looking forward to seeing the material.

Very best,

These were in pretty good shape…

when collected. And I got them into the dehydrator not long after collection. So I think this may be some useful material.

It’ll be time to put together another package soon. This will be included.

I suggest pachysperma.

We’ve never found a specimen of pachysperma that yielded DNA…if I remember correctly. This could be a very interesting find.
