Mushroom fields are the rarest biome in the overworld — most worlds put them thousands of blocks out to sea. Every seed here has a mushroom island within 600 blocks of spawn, and several put you practically on the mycelium.
These lists retain the 1.21.4 generation model for older worlds and modpacks. Use 26.3 lists for Wilderness Bound; new biomes can change the same seed's layout.
Computed for Java 1.21.4. Spawn and terrain-dependent structure placement remain estimates.
For the current Java 26.3 release, see the main mushroom island seeds — or the same list for 26.3 · 1.20 · 1.19 · 1.18 · 1.16. All 1.21.4 lists live under best 1.21.4 seeds.
