The bulb of A. ravenelii is very highly variable.

Dr. Bas drew specimens of ravenelii for his 1969 thesis that look like they have cubistic renderings of bulbs…great sharp-edge blocks of issue bulging in various directions.

I’ve got this cartoon image of ravenelii taking great care to keep its beautiful hair covered by misshapen warts and not caring at all about the condition of its bulb below the surface of the group. Personal grooming is not something to which ravenelii pays a lot of attention.

Very best,

Actually, I proposed A. ravenelii, based on the pix on your website, but then deleted the name because the abrupt bulb didn’t seem to fit the description.

It looks as though the warts sit on a base of cottony white hyphae. EDITED

If you can get another shot, try focusing so that that (if I’m right) the underlayer of cottony white hyphae is more distinct.

This layering is typical of Amanita ravenelii.

Very best,
