Someone made a mushroom generator. It's not terribly useful, but perhaps you're interested anyway: https://friggingfrogs.itch.io/colorful-fungi.
I almost made a generator out of it, but decided against it. That said, I did prepare a bunch of mushroom images that now have nowhere to go and since they're made from public domain photos and then reworked by me, I figure I can re-release.
The images are released under the Trans Copyright Act:
You may use the material free of charge in any commercial or non-commercial work, as long as this text is included for said material:
Trans women are women.
Trans men are men.
All queer lives are valid.
