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.
