I like the name. Boreal(northern), soror (sister). Makes me want to study latin and greek.

Yet another name…

that has been applied to this type amanita is “Amanita strangulata.”

I agree, Phil. The names are changing too often to accommodate the authors of field guides. One nice thing about Mushroom Observer is that the forum provides a relatively easy way for hobbyists like us to keep up with he changes.

Having said this, changes occur in accordance with rules that govern nomenclature. The name “Amanita borealisorora” is listed as “nom. prov.”, meaning it’s admittance is still contingent upon certain acceptance criteria. Thus, “Amanita ceciliae” may or may not still be the best name to apply here, dependent upon your point of view. I believe this discussion has taken place at least one other time here on MO… specifically in reference to this species.

Reading your comments about the basal structure of this mushroom increases my confidence about its identity. IMO it’s good to allow old names to stand alongside new ones with appropriate levels of confidence. Given the provisional status of the name “Amanita borealisorora”, you and Herbert have convinced me to adjust my proposal/votes accordingly.

This was formerly A. inaurata. If names continue to change-and they will- authors will have to find a way to electronically update our books. The bottom of that stipe did have charcoal spots on it which made iding it easy. The bottom portion was broken off during handling, or I would have photographed it.

the eastern NA version of “ceciliae” is borealisorora. Looks like this specimen is one of these. But one of the key characters, the gray basal volva that partially collapses and partially disintegrates, is not seen here.
