Recognized by sight: This is A. jacksonii, but there is something EXTREMELY weird going on with the gills! Is this the result of a parasite?

I had seen two, and you got them both. It’s very kind of you to take the time to fix them.

Very best,

Rod

Hello, Patrick.

Just woke up after a long, long day yesterday traveling to and from DC and
participating in the March on Washington.

It looks a bit as though a Hypomyces is starting to attack the entire fruiting
body. There’s a white film over the caps of many of the specimens; and the stem
surface also seems abnormal. There is another disease that attacks some species of section Caesarea…Mycogone rosea.

The margin of the cap is too yellow too soon for jacksonii, I think.

Very best,

Rod

The normal ones all have yellow gills and stipe

Perhaps the color is from the Hypomyces, or whatever it is. I have never found other Caesareae in the picnic area of the park. A. banningiana has been found, but farther away, up in the hills. See my recent A. jacksonii observation.

and it could be a mold or hypomyces of some type. It seems odd that it would affect the button, which does not look much like Aj. Also, Aj in my neck of the woods has yellow gills, ring, and stipe – distinctly yellow even when old. I guess most any mushroom can split as this cap has – especially amanitas – but the striate cap I look for is not here, or it is hidden. The last one I saw had a serrate margin.

but how are you so sure that the base amanita is a jacksonii?
