bloodworm: would you mind adding information about your microscope to your home page? …and come to think of it, post the info about your camera, too. I am also an aspiring mycologist, so I will update my home page with same info.

Spores look like they are becoming ellipsoid …

in the micropicture, that with the upstanding limb on the bulb and the bulb looking like it is narrowing to something like an upside down conical shape on the bottom, belonging to the Phalloideae, located in the eastern US, etc. suggests Amanita elliptosperma as a possibility. I haven’t worked on that species for several years; however, I’ll check to see if what I have is on-line…that’s the goal.

Did you try to expand it after collecting to the point at which it dropped spores?
