Very kind of you.
You can also often get KOH from some co-ops and farmer’s supplies as potash.
And cheaply too. I have purchased twice from this company with no issues.
I would also be happy to send you some if online ordering isn’t possible. Email via this site if you need some.
KOH: Maybe from a Chem. Dept. at nearby college or university? You only need 5% solution to get a yellow reaction (although closer to 10% makes it more dramatic).
I just checked to see if we had Coker’s picture of gwyniana on-line on www.amanitaceae.org, and we don’t. I will scan the original publication tomorrow and try to get the image on-line before the weekend is out. [Bug me if it’s not there on Monday.]
The glass plates (I think) of Coker’s photographs are at Chapel Hill. It would be an interesting project to raise the funds to get them on-line and linked to the original publication, which would also have to be placed on-line. Bas said that Coker’s notations on his dried collections were the best Bas saw in any North American herbarium.
Coker was a very good photographer, too.
If you have the opportunity to dry this specimen, it could prove very valuable in sorting through the ellipsoid-spored white taxa in sect. Phalloideae in North America.
