Thanks for the offer. And… For my purposes, it is really important the a dried specimen matches to a specific photograph.

With any luck, you’ll hit on this species again in the same (or another place) and get a collection/photo link that’s certain. If you place a scrap of paper with a number on it to the side of the photo (where it can be cropped out) and put the same piece of paper in the bag with the specimen and then on the dryer with the specimen. You’ve got a CSI-type track from collection to photo and back. By putting different numbers on different pieces of paper, you (of course) can avoid some of the screw ups that can happen. Having a little notebook to track the numbers, the dates, the sites, and your field IDs brings you up a notch in managing your data, photos, collections, etc. After the notebook comes a computerized version of the notebook, then…. You are in danger of getting hooked on the databasing of everything….etc., etc.

Very best,

I have one dried specimen and spores from that patch, but I am unsure which photograph matches it. I think it is the second photo I posted where the mushroom is picked. I have more photos on my HD of fruitings from this patch as well.

If this is of any interest to you, let me know.

In posting the taxon page for ameripanthera…

…I discovered the photos I took of this species myself are really old and crumby looking.


I’m looking for dried collections that are backed up by photos posted here on mushroomobserver.org … or the other way around…good photos posted on MO that have dried vouchers that can be shared with RET.

If the material conforms with already collected material of ameripanthera, the dried material and the images will both improve the future publication of the species name…if I get to it in this lifetime…and will enrich the taxon page for ameripanthera on www.amanitaceae.org.

Thanks in advance for any help that can be provided.

Very best,


Because Tim’s post brings up the question…

Look at the technical tab.

I have never seen such a dark pantherina myself, altho I know that they occur. According to Michael Beug, who has analyzed the toxins, these dark forms are the most toxic in a spectrum of pantherina color from darkest to pale tan.

Pigment is often more concentrated in the young cap’s skin.


No problem

Thanks for the ID confirmation. I don’t usually find them quite this dark.

Thank you, Tim

Thanks for the added picture, Tim.

I think your ID is probable.

Very best,

I added a picture of the base of another specimen picked on a different date in the same area, I know it isn’t ideal but it is all I have!

Do you have a pic of the base?

Any pix of the base?
