I agree that at the top of the stipe that is the remnant of a weakly structured partial veil.

In the material of praelongispora that I was examining, the dried volva formed a thin, but distinct line around the top of the bulb at about the point at which the curve of the bulb’s “shoulder” began…right at the edge of the nearly flat top of the bulb. In the dried material the limb was very short.

I’m going to try to get Dr. Bas’ drawings of the dried material he examined scanned and on the website. It is close to what I saw, but not exactly the same.

Very best,

Rod

Thanks for taking a look. The specimen I saved ran through the dehydrator and the bulb has sand on it, so I am having a tough time seeing any limb. There is a fine ridge at the edge of the bulb furthest from the stipe, but I can’t decide whether it is sand, volva, or other. Would you say in the first photo that there is a bit of annulus at the very top of the stipe near the gills?

Amanita abrupta usually has a more persistent…

partial veil with many fibrils underneath connecting the lower side to the stipe surface. Also there is a broader top to the bulb and, at least, a few rather thick (relative[y speaking) hyphals “cords” attached at the point of the bulb.

In the top photo on the lower side of the bulb (side toward the bottom of the picture) there seems to be a small piece of a limb. Is the material still available to check whether there is a very short, irregular limb around the top of the bulb and not too close to the stem?

I worked up some older material from Georgia last night and reintroduced myselfe to Amanita praelongispora (the picture on WAO has an atypically narrow bulb).

If you have this species, the spores should be dominantly cylindric.

Very best,

Rod
