Verpa bohemica is a species of fungus in the Morchellaceae family. Commonly known as the early morel (or early false morel) or the wrinkled thimble-cap, it is one of several species known informally as a "false morel". The mushroom has a pale yellow or brown thimble-shaped cap—2 to 4 cm (0.8 to 1.6 in) in diameter by 2 to 5 cm (0.8 to 2.0 in) long—that has a surface wrinkled and ribbed with brain-like convolutions. The cap hangs from the top of a lighter-colored, brittle stem that measures up to 12 cm (4.7 in) long by 1 to 2.5 cm (0.4 to 1.0 in) thick. Microscopically, the mushroom is distinguished by its large spores, typically 60–80 by 15–18 µm, and the presence of only two spores per ascus.
In the field, the mushroom is reliably distinguished from the true morels on the basis of cap attachment: V. bohemica has a cap that hangs completely free from the stem. Although widely considered edible, consumption of the mushroom is generally not advised due to reports of poisoning in susceptible individuals. Poisoning symptoms include gastrointestinal upset and lack of muscular coordination. V. bohemica is found in northern North America, Europe, and Asia. It fruits in early spring, growing on the ground in woods following the snowmelt, before the appearance of "true morels" (genus Morchella). The synonym Ptychoverpa bohemica is often used by European mycologists.
