There are two types of Stalagmite Biomes, each having different features, both rarely spawning Nightmare Fissures.
The first type is abundant with normal Stalagmites. However, being their natural habitat, these areas are also heavily infested with Cave Spiders and Spitters which live in Spilagmites. There may be branches of this biome which are not infested, depending on World Generation.
Thulecite Sinkholes are usually found in here.
