Is the Pezizaceae poisonous?

There is a well-known mushroom in the Pezizaceae family called pink crown (Sarcosphaera coronaria). It was once thought to be good food, but this mushroom is in reality prone to be rich in a heavy metal element called arsenic. Eating mushrooms with high contents of heavy metal elements can cause stomach pain and even death. There have been several reported cases of poisoning from this species in a few European countries. Moreover, some mushrooms of the genus Peziza are also considered toxic, such as blistered cup (Peziza vesiculosa). Most members of the genus Peziza are difficult to correctly identify without the use of a microscope. So when you find these mushrooms, do not collect or eat them at random. If you experience discomfort after ingesting them, seek medical help as soon as possible.
