I have been blithely going along with the idea …

that if I got a yellow reaction to KOH on a white “destroying angel” in the NE US I could say something like “bisporigers” group and let it go at that until I needed more details for some project. Now, I’m afraid our life has become more complex. Amanita suballiacea, which was known from the deep south and the Mississippi valley region has not been found in both Michigan and Connecticut. Oddly I came into possession of the two collections on the same weekend.

When something looks like bisporigera we now need to check that determination against A.sp-O01” and A. suballiacea. The latter has spores that are much more frequently broad ellipsoid to ellipsoid than the spores of bisporigera and “sp-O01”.

The WAO website is getting closer to uptodate with this new information with regard to suballiacea and “sp-O01” than with regard to bisporigera.

Genetic studies have been key to bringing this information to the fore. It will take time for the moprhological information on the website to be corrected.

Very best,

Rod
