The Thermoprotei is a class of the Thermoproteota.
The Desulfurococcales is an order of the Thermoprotei, part of the kingdom Archaea. The order encompasses some genera which are all thermophilic, autotrophs which utilise chemical energy, typically by reducing sulfur compounds using hydrogen. Desulfurococcales cells are either regular or irregular coccus in shape, with forms of either discs or dishes. These cells can be single, in pairs, in short chains, or in aciniform formation.
Thermoproteales are an order of archaeans in the class Thermoprotei. They are the only organisms known to lack the SSB proteins, instead possessing the protein ThermoDBP that has displaced them. The rRNA genes of these organisms contain multiple introns, which can be homing endonuclease encoding genes, and their presence can impact the binding of "universal" 16S rRNA primers often used in environmental sequencing surveys.
The Pyrodictiaceae are a family of disc-shaped anaerobic microorganisms belonging to the order Desulfurococcales, in the domain Archaea. Members of this family are distinguished from the other family (Desulfurococcaceae) in the order Desulfurococcales by having an optimal growth temperature above 100 °C, rather than below 100 °C.
Thermofilaceae are a family of archaea in the order Thermoproteales.
In taxonomy, the Thermoproteaceae are a family of the Thermoproteales.

Stetteria is a genus of archaeans in the family Desulfurococcaceae. Up to now there is only one species of this genus known, Stetteria hydrogenophila.
Sulfophobococcus is a genus of the Desulfurococcaceae.
Thermodiscus is a genus of archaea in the family Desulfurococcaceae. The only species is Thermodiscus maritimus.
Thermosphaera is a genus of the Desulfurococcaceae. They are a group of prokaryotic organisms which have been discovered in extremely hot environments such as sulfur springs, volcanoes, and magma pools. Isolates of Thermosphaera were first identified in 1998 from the Obsidian Pool in Yellowstone National Park.
In taxonomy, Hyperthermus is a genus of the Pyrodictiaceae.
Pyrodictium is a genus in the family Pyrodictiaceae. It is a genus of submarine hyperthermophilic Archaea whose optimal growth temperature range is 80 to 105 °C. They have a unique cell structure involving a network of cannulae and flat, disk-shaped cells. Pyrodictium are found in the porous walls of deep-sea vents where the temperatures inside get as high as 400 °C, while the outside marine environment is typically 3 °C. Pyrodictium is apparently able to adapt morphologically to this type of hot–cold habitat.
Pyrolobus is a genus of the Pyrodictiaceae.
Thermofilum is a genus of archaea in the family Thermofilaceae.
Ignisphaera is a genus of the Desulfurococcales. Ignisphaera aggregans is a coccoid- shaped, fourth type strain that is strictly anaerobes with anaerobic respiration. This archaea species are hyperthermophiles that were found in New Zealand's hot springs in Kuirau Park, Rotorua.
