Peziza vesiculosa

Peziza vesiculosa is a species of apothecial fungus belonging to the family Pezizaceae. This is a common species of Europe, with scattered records in other parts of the world. The pale, cup-shaped ascocarps can grow quite large (up to 10 cm (3.9 in) in diameter) and often form densely packed groups. It is found on nutrient-rich soils, rotting straw and manure and can often be seen on compost heaps. The edibility of Peziza species, including this one, is poorly known but this species is often considered poisonous.
