Glow Lichen can generate mid-air with no supporting blocks attached. I found this issue in the Portal Room in a Stronghold, but I am unsure if it is limited to that.
Glow Lichen would break if I added a supporting block and then remove that new supporting block.
I was on a Single Biome world as Dripstone Caves
