Observation 32218: Amanita whetstoneae Tulloss nom. prov.
When: 2009-09-05
No herbarium specimen

Notes: Initially, I believed this was one of the Amanita vaginatae group, but I’m not confident and would appreciate others opinions.
This appears to be an aging specimen with the cap edges drawing inward. Nevertheless, this was a very attractive mushroom with an interesting textured sheathing that reminded me of birch tree bark.

Thanks Debbie. I’m grateful to have this site for learning from others with more experience. The design of the group is excellent given the complexities of fungi and in helping folks like me who have just discovered how pleasurable and interesting mycology is. Thanks again, Mark

good eye.

I went down that same wrong path when I collected this species for the first time. It’s quite distinctive, as well as reminescent of the vaginatae.

You’re welcome, Mark.

I think this has as good a chance of being A. whestoneae Tulloss nom. prov. (of sect. Amidella) as it does of being in sect. Vaginatae.

Very best,
