Analysis of the ribosomal DNA of many of the Pezizales showed the genus Gyromitra to be most closely related to the genus Discina, and also Pseudorhizina, Hydnotrya, and only distantly related to Helvella. Thus the four genera are now included in the family Discinaceae.
Gyromitra comes from gyro meaning convoluted and mitra meaning turban.
Some types of Gyromitra are highly poisonous when raw due to the presence of Gyromitrin, although some species are edible when cooked and Gyromitra are sought after in Scandinavian countries. Widespread hemolysis has been reported from ingestion which can result in renal failure. Methemoglobinemia has also been seen, although it is typically responsive to treatment with methylene blue. Seizures can also develop via inhibition of the neurotransmitter GABA.
