This has an interesting set of tanning processes, but it's funny how SEO saturated this topic is. There are some video results that are probably useful, but 99% of my searches are turning up commercial garbage, and nothing to do with actually making mushroom leather. Iirc from a podcast, sodium carbonate is used to soak amadou mushrooms for a felt-like material, which Paul Stamets uses for his hat. You'll probably need to learn the jargon and terms of art specifying the exact types of mushroom fabrics and materials that can be produced. Good luck!
