Comment on Mycelium vs. Hempcrete as insulation bricks - Advice needed

I can’t comment on the mycelium idea, but I don’t see how hempcrete would help much with your goals of accustic and heat isolation.
I would probably go a different route and use areated cement blocks. They can be bought off the shelf and cut to size, but you can also mix cement slurry with aluminium powder to have it bubble up before the hardening of the cement takes place.

The cool thing about it is that you can form it to any shape you want.
For acoustic insulation, you need more than just a nice material. You need physical structures that allow the sound waves to break and dissipate. I already thought abour the puffed up concrete, but as a sheet only being a few centimetres thick, it weights too much and reflects too much noise.
Acoustic foam, you know, those with pyramids, is great, but often flammable, and, you guessed it, another source of non-recyclable plastic trash some day. I will definitely consider it, but only if I don’t find something else.

Mushrooms in general aren’t great to have in place where people are going to live or be for long time. One of my relatives caught (dunno the english name for it) a condition where mushroom spores cause infection due to inhaling them, when working with mushrooms without respirator, it was pretty bad. Just an anecdote, maybe it’s not really a problem with dead ones.

Sure, mushroom spores can be unhealthy. But they’re only produced by ripe fruiting bodies, and in this case, we have mycelium, basically the “root structure”.
