Observation 136393: Amanita sect. Vaginatae sensu Zhu L. Yang
When: 2013-06-07

Notes: These were growing in mixed woods.
Caps up to 5.6 cm across with striations up to 9mm long.
Cap color seemed to have a slight greenish tint.
Spores were ~ 9.0-12.0 X 8.0-10.1 microns.
Q(ave) = 1.19. Q(range) = 1.11-1.29.
Closest match that I could find on Rod’s regional checklist was sp-T33.

Thanks for posting this observation with the micro detail.

For persons not familiar with the regional checklist to which Ron refers, it can be found here:

I think there are a couple of other possibilities for an ID because of spore size variation and the small samples sizes for spores measurements of some taxa in the thecklist.

I’m very interested in the species of sect. Vaginatae so I tried to get some data on as many apparently different species as possible; however, I haven’t been able collect enough data to bring the sample sizes up to where I would prefer to have them.

I think that sp-V01 and sp-T16 might also be possibilities in addition to sp-T33. The macroscopic appearance of sp-T16 is especially similar to the appearance of the mushrooms in your photos.

I’d very much like to see your material if that’s possible.

very best,

Rod
