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.
1.20 (Trails & Tales) added cherry groves and buried trail ruins to world generation, and 1.20.1 is one of the most-pinned modpack versions — plenty of worlds are still being started on it. Every seed below was verified on 1.20's own generation, not back-ported from a newer list: 1.21 changed worldgen (trial chambers, then the pale garden), so a list verified there can't honestly claim these coordinates.
Verified for Java Edition 1.20 (Trails & Tales). Biomes, terrain and structures are identical across 1.20 – 1.20.6, so any 1.20.x world matches these maps — the only generation change in the patches (1.20.2 made diamond ore more common in the deepslate layers) doesn't affect anything these cards measure.
