Can place mushrooms on non dirt blocks

Confirmed in 1.14.30. Only blocks I found that don’t support mushrooms are glass, ice, scaffolding, and anything non-full or light-producing.

However, I’ll say that to me it makes sense that mushrooms can grow on wood variants and many other quasi-natural blocks like slime and coal.

Thank you for your report!

I think you are describing a different issue, possibly the fact that mushrooms cannot be planted where the light level is >11. That's also likely an intended game mechanic because in real life fungus generally grows in dark places.

i will show a image that mushroom can plant any block when at deep caves.Please do reopen back my ticket @GoldenHelmet.
