The Morchellaceae is a family of ascomycete fungi. The best known members are the highly-regarded and commercially picked true morels of the genus Morchella, the thimble morels of the genus Verpa, and a genus of cup-shaped fungi Disciotis.
Analysis of the ribosomal DNA of many of the Pezizales showed the three genera Verpa , Morchella, and Disciotis to be closely related. Thus they are now included in the family Morchellaceae.[1]
Genera description
The three genera of Morchellaceae are distinguished by ascocarp morphology. Morchella species have an ascocarp with a sponge-like pileus, with a hollow stipe and pileus. Verpa species have a cup-like or thimble-shaped, smooth or wrinkled pileus above a hollow stipe. Disciotis has a cup-like pileus with vein-like hymenial folds and a small or nonexistent stipe.[2] The ascospores are ellipsoid, smooth, and usually hyaline.[3]
