The specimen in your photographs has a white, thin, membranous partial veil. The partial veil of magnivelaris is thicker a distinctly yellowish cream color and is described as felted. This is a very distinct difference. While we seem to be in a period of some turmoil with regard to taxonomy of white destroying angels, I think that the most probable determination for your material is either A. “sp-S04” or A. elliptosperma.

I just added a new photo (Eva Skific’s) of magnivelaris here:


Very best,
