Lichen

Lichen is a thin plant-like block. It has a regular variant and a smeltable Dead variant. The regular variant generates on the surface in Deep Waters biomes, often on Cragrock Spires, as well as underground in Caverns and Lake Caverns and on Idol Head Statues.

Smelting Recipe[]

Result	Ingredients	Recipe
Dead Lichen + 0.1 XP	Lichen + Any fuel

Growth and Decay[]

Regular Lichen naturally goes through cycles of growth, spreading to nearby blocks slowly over time and eventually dying out.

Dead Lichen does not grow.

Collection[]

Lichen must be harvested with Syrmorite Shears to be collected. When harvested with a Sickle, it instead drops a Lichen Clump, which can then be ground into Ground Lichen.

Compostability[]

Regular Lichen has a compost process time of 7 minutes and 30 seconds and a compost amount of 6. Dead Lichen has a compost process time of 2 minutes and 30 seconds and a compost amount of 6. Visit the Compost page for more information regarding the composting mechanic.

Igniting[]

Lichen can be used to create fire by holding right-click on either its placed or dropped form with an Octine Ingot. Lichen that is adjacent to or on a Block of Octine will also catch fire, although this fire will not spread to further Lichen blocks.
