We have recieved this material and accessioned it to Rod’s Herbarium. We have scheduled it for DNA sequencing.
A edit of substance was made to the above cited comment.
The specimen has a very long stem, compared with other A.bisporigera
show a yellow response to KOH-5% taste
There are five probable species of these “angels” that I know that show a yellow response to KOH (5 – 10% will give a strong reaction).
Amanita sp-O01 often (perhaps not always) has a somewhat “squat” appearance (shorter stem than others listed here):
__Amanita sp-bisporigera04 is known from DNA sequences (often rather large with long stem):
__Amanita sp-bisporigera05 is known from DNA sequences (EDITED: known from only one specimen with pale orange-tan in the center of the cap…not known if this color is always present in the species END OF EDIT):
We are making some progress with learning more about these species (distribution, anatomical characters, etc.) thanks to our own collecting this year and thanks to collections sent to us.
All of the species are known to contain amatoxins or probably contain them.
To establish range information, I am particularly interested in material from Canada in general.
Thank you for your response.
it is large
This looks like one of the large white destroying angels.
I don’t know if Amanita suballiacea extends into Ontario. I have material from Michigan. There are at least two undescribed taxa in the group that I know from only a few collections…although I think at least one of the two is very common.
I’m assuming from the size of the leaves in the picture that this specimen was rather larger. Is that right?
