How to reproduce
Locate a mushroom room, either by finding one naturally generated:
/locate structure minecraft:mansionOr by spawning one in directly:
/setblock ~ ~ ~ structure_block{mode:"LOAD", name:"woodland_mansion/1x2_a7"}→ ❌ Note that no mushrooms spawn.

While testing for this bug, I came across a mushroom room whose dirt got overrun by moss from a nearby lush caves biome (picture attached). Is this worth reporting as a separate issue?

Yes, that's a separate issue that should be reported, the "same issue" with the stone-types getting replaced by dirt/granite/diorite/andesite/ores also got fixed.
Confirmed in 23w16a.
Loaded up a world in 1.20, and somehow the mushrooms are present.

I saw an another room that mushrooms are present in 1.20.1 besides already mentioned case. And I tried to generate it with structure block, and it had mushrooms. It dropped as item immediately tho - this might be brightness issue I think.
It is, order may have changed slightly in 1.20 so that the mushrooms are in darkness before their brightness check, rather than checking immedietly when placing the structure block by block.
Also tested in 1.20.1 and two mansions I went to had the room and generated with them.
EDIT: It may have been a mod that was fixing it....
Confirmed in 1.21.3
Can confirm in 20w49a. Absolutely no mushrooms are generated here.
