The Morchellaceae are a family of ascomycete fungi. According to a standard reference work, the family has contained at least 49 species distributed among 4 genera[1], but in 2012, 5 genera producing the sequestrate and hypogeous ascoma have been added[2]. 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. The remaining four genera produce the sequestrate fruit bodies.
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.[3]
General description
Other than the anamorph genus Costantinella, the three remaining 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.[4] The ascospores are ellipsoid, smooth, and usually hyaline.[5]
