Thank you so much for your help!
The positive reactions are recorded for white capped species.
Species that are supposedly always negative in North America are the white variants of A. phalloides, A. elliptosperma, and A. magnivelaris. The postives in North America include A. bisporigera (but every once in a while i find one or hear of one that did not change…I have checked this morphologically and genetically…there are a small number of fruiting bodies of bisporigera that are KOH negative), A. ocreata, and A. suballiaceae. There are also KOH+ undescribed white species of the Phalloideae in eastern North America that turn yellow…we just confirmed another one this evening…which brings us to at least four. There are partial pages for three of these on the WAO website:
The fourth still needs to be sorted out a bit more before we create a page, but it seems that there will be another page.
I hope this helps.
The cap turns yellow with KOH, is that typical of Phalloideae?
5 to 10 percent KOH (potassium hydroxide) solution on the cap?
