I don’t think it is A. fulva

Nor is it the NE N. American species that is often called A. fulva. The fact that the cap seems to have alternating light and dark zones and is robust is helpful. There is a group of such mushrooms which might be differentiated by the colors of the zones (but I’m not sure). They are not very common, but usually reoccur each year in regions where they do occur. I mostly associate the one with pale grayish yellow or pale olive yellow zones with mixed hardwood forests; however, I’m not sure that I have ever seen this particular zone pattern-color combination previously.

For these reasons I’ve suggested Amanita sp. (section Vaginatae) as the temporary classification.

I am interested in obtaining well-dried, well-photographed, and well-documented collections of unusual members of section Vaginatae from anywhere in the world.

Very best,


No, this one is big

about four or five inches tall, and really meaty. It stuck me as very large and stout for A. vaginata.

Was this as small a species as it seems (down in the grass)? Did the center of the cap appear to have lost its coloration?

If the answers are “yes,” then this could be my unnamed species N9 of section Vaginatae. There will be part of a technical description of this codenamed taxon on the new Amanitaceae website when it is ready for release.

Right now you can see a picture and spore data for this species on the New Jersey Pine Barrens checklist on the old Amanita Studies site.
