I normally build two farms as that way it seems to go faster. Here's my truffles' house. I didn't know truffle worms spawned above ground.i tend to make them on the surface, or even on sky island height, so that i only need to build a house and get the truffle in it as soon as i hit HM
coolHeres mine. I have no idea what I was going for when I made this but I like it.
the walls look like structural supports. CoolView attachment 64180
Sorry for putting full image (idk how to make it small)
I didn't know glowing mushrooms grew on dirt. Also don't the trees give you more though?Since shrooms only need 1 block to grow, you should make it dirt, empty, dirt for rows. Then put actuators for each dirt, wire it, attatch lever or something to it and then all the shrooms fall down, the one im using drops like 300 shrooms each time. Very easy and efficient.
