I’m trying to save the specimen. Maybe we can get more out of it.


Thank you, Rod,

for your efforst in ID-ing this interesting amanita. It’s a shame the specimen is too young to make mature spore for a conclusive ID. We were all excited about this one when we found it — it was in perfect condition, untouched by bugs or decay. Alas, we found it too early! John took a GPS reading of the spot, so we know where to look for it next time…

I was able to find a few spores in lateral view for measurement.

Much of the gills surface is immature however. The spores suggest the possibility of an immature specimen of Amanita homolae; but this has never been collected this far south previously. On the other hand A. homolae is not well known. This collection probably will not produce typical results…whatever the species to which it belongs…unfortunately.


The spores are inamyloid and subglobose.

I didn’t get to it until 10 pm.

It’s pretty likely that this is in sect. Vaginatae. It’s immature and has been refrigerated. I’ve got to put it in the dryer in order to have a chance to save it. We may never have a name for it. The appearance is so distinctive. I hope that it is found again.

Very best,


I’m glad you posted images.

The first thing this a.m., I can at least eliminate the possibility of whetstoneae with Melzer’s reagent on the spores.


Yes, Rod

Nina, John and I found it at the North Gate section of the preserve. It would be nice if you could put a name to it…

this p.m. by John and Nina Burghardt.

At least, I think this is the specimen that is now in my ridge. I will take a look at it tomorrow.

Very best,


Could be.

Looks promising. If so it’d be a rare find.

Amanita williamsiae (nom. prov.)

This could be “Williams’ Great Ringless Amanita”.
