"above ground" and "surface" classifyes as anything that's not Underground (check thisout). For the mobs you specified here, non of them are hardmode (only Giant Fulgy Bulb, Fungo Fish, Truffle worm and Glowing snail are hardmode).

All in all, I think that your surface mushroom biome should be good as long as it's not in Underground.
