Verpa bohemica

Species of fungus

Verpa bohemica is a species of fungus in the family Morchellaceae. The synonym Ptychoverpa bohemica is often used by European mycologists and it is commonly known as the early morel or the wrinkled thimble-cap. The mushroom has a pale yellow or brown thimble-shaped cap—2 to 4 cm in diameter by 2 to 5 cm long—that has a surface wrinkled and ribbed with brain-like convolutions. A feature distinguishing the species from true morels, the cap hangs free from the top of the stem, which is lighter in color, brittle, and up to 12 cm long by 1 to 2.5 cm 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.
