A glow lichen is a non-solid, light-emitting block. It can generate, or be placed, on any side of a solid block.

Obtaining

Breaking

Glow lichen can be destroyed with anything, most efficiently with an axe. However, using shears is the only way to obtain glow lichen. Enchanting shears with Efficiency II allows for instant mining.

Natural generation

Glow lichen generates naturally in the interior of caves (at any height) on the surface of stone, andesite, diorite, granite, calcite, tuff, deepslate, and dripstone blocks that are exposed to air or water sources.​ As well as within or upon generated structures, or sometimes even exposed to some surface light. It can be found underwater, but cannot generate in the deep dark biome.

Post-generation

Using bone meal causes glow lichen to spread to a random adjacent block if possible, otherwise the bone meal is not consumed. By fertilizing one lichen with bone meal, it is possible to cover the sides and the top of an adjacent block, but not the back. Otherwise, glow lichen does not spread naturally.

Usage

Light

Glow lichen emits a light level of 7.

Placement

Multiple glow lichens can be placed in the area of one solid block, such as covering three sides of a corner. When such glow lichens are mined, all glow lichens occupying the same block are also mined. Mining with shears causes all glow lichens in the block to drop.

Glow lichens cannot be broken by flowing water or lava, similar to signs. Therefore, they may be used to control the flow of water, but not lava, as Glow Lichens are flammable.

Composting

Placing a glow lichen into a composter has a 50% chance of raising the compost level by 1.

			21w11a				Bone meal can no longer be used on glow lichen if it has no blocks to spread to.
							Glow lichen can now be used on a composter.
			21w13a				The model of glow lichen has been tweaked so that the backside texture is mirrored.
			21w20a				Glow Lichen now drops the correct amount if there's more than one on a block.

1.17.40 Experiment Caves and Cliffs			beta 1.17.40.20				The maximum Y-level that glow lichen can generate has been increased to Y=120.
1.18.0			beta 1.18.0.22				Glow lichen is no longer able to generate anywhere outside of caves.
1.18.10			beta 1.18.10.26				Decreased the light level emitted by glow lichen from 10 to 7 to match Java Edition.

Trivia

• This block was hinted at by Henrik Kniberg, who explained that the glowing ores at Minecraft Live 2020 were prototypes for this.
• If the player removes all directional states using a debug stick, the block becomes invisible, but the light emission remains, unless another block is placed there.
• In real life, the lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungus species in a symbiotic relationship.
