Warped Wart Block is the cyan-teal block that forms the leafy canopy of huge warped fungi in the warped forest, a biome added to the Nether in Minecraft 1.16. Unlike Nether Wart Block, Warped Wart Block has no crafting recipe and no item counterpart — there is no "warped wart" item to place in a grid. The only way to obtain Warped Wart Block is to mine it directly from the tops of giant warped fungi. Warped Wart Block breaks with any tool and always drops itself, but a hoe clears it fastest, and Silk Touch is not required.

Warped Wart Block is purely decorative and, despite the brewing-flavored name, has no potion use and no food value. Builders prize Warped Wart Block for its bright turquoise tone, which pops next to the orange glow of Shroomlight and forms a vivid complementary contrast with the deep red of Nether Wart Block. Warped Wart Block is renewable: grow your own huge warped fungi by using Bone Meal on a Warped Fungus planted on Warped Nylium, then harvest the canopy for an endless supply.
