About these 1.18 seeds

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.

1.18 (Caves & Cliffs Part II) rewrote terrain generation completely: world height stretched to Y −64…319, six new mountain biomes, and cave systems bigger than anything before it. It's also where modern seeds begin — a 1.17 seed generates a totally different world — and 1.18.2 is still a heavily-played modpack version. Every seed below was verified on 1.18 generation itself.

Verified for Java Edition 1.18 (Caves & Cliffs Part II). Biomes, terrain and structure locations are identical across 1.18 – 1.18.2, so 1.18.2 modpack worlds match these maps.

For the current Java 26.3 release, see the main mushroom island seeds — or the same list for 26.3 · 1.21.4 · 1.20 · 1.19 · 1.16. All 1.18 lists live under best 1.18 seeds.

Frequently asked questions

How is this different from the main mushroom island seeds page?
These seeds are computed for Java 1.18. The main mushroom island seeds list targets Java 26.3. Match the version on the card; older versions can generate different biomes and structure positions.
Which releases do these seeds work on?
The whole 1.18 line — 1.18 through 1.18.2, including 1.18.2 modpacks: biomes, terrain and structure positions are identical across the patches (1.18.2 only fixed cosmetic generation bugs like underwater snow patches). Later versions keep the same terrain engine but add structures and tweak placements (1.19's ancient cities, 1.20's trail ruins), so verify on our newer lists if you're playing past 1.18.
Do these seeds work on Bedrock Edition?
No — Java and Bedrock generate different worlds from the same seed. These lists are Java Edition only.
