Discina species, Disciotus venosa and Gyromitra melaleucoides (illustrated here) are difficult to identify because it is hard to find mature specimens with spores. Disciotis venosa , a close relative of the morel, is edible if well cooked. However, all of these species are poisonous if eaten raw. Several are suspected of containing hydrazine compounds and are likely to produce abdominal pain, severe headache, and repeated vomiting accompanied by diarrhea commencing between 30 minutes and 2 hours after ingestion. These mushrooms, though not choice, are used as extenders in mushroom cookery.
