The first photo you posted shows a mushroom with petals.

The last one looks like a cup to me.

Some of the others kind of look like mushrooms if you squint your eyes a little.

Unfortunately none serve as any kind of evidence for mushroom use whatsoever.

You make a lot of points and references in your posts, which makes it a bit difficult to do them justice, but, to start I would ask you if you have ever read Wassons (et al) book on Soma being fly agaric? I have, and his argument is thin at best. I also studied Sanskrit for two years, which does not make me an expert at any level, but does allow me both opinions on how it is translated and also insights into the work of professional Sanskritists like Wendy Doniger who collaborate on crank projects like Wasson's.

Concerning my experience, I lived in India for three years and was initiated into a division of the Nath Sampradaya that uses aghori practices, by a "guru", who used a skull as a cup and had participated in various charnel ground practices, who gave me a mantra and taught me certain practices. That was twenty years ago, and I understand it does not make me an expert or give me special credentials, but it does mean that I have had a good look at the thin end of the wedge and saw lots of wired and wonderful and horrible things, but no mushrooms.
