Eating mycelium

So as you can see I had a very thick overlay on this cake, so I decided to scrap it off with a fork and it looked to fluffy and bouncy like a marshmallow. I had to just try a nibble, and it honestly tasted great! It tased like a really fluffy mild tasting mushroom. I usually hate the taste of these kinds of mushrooms, so I was really surprised. Also it didn't bruise blue, so I don't think I'll be tripping at all from the nibbles I had. Has anyone else ever tried the mycelium?
