Morchellaceae
The Morchellaceae are a family of ascomycete fungi in the order Pezizales. According to a standard reference work, the family has contained at least 49 species distributed among four genera. However, in 2012, five genera that produce ascoma that are sequestrate and hypogeous were added. 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. Genera '' Costantinella'' (anamorph) '' Disciotis'' (terrestrial) '' Morchella'' (terrestrial) '' Verpa'' (terrestrial) '' Kalapuya'' (hypogeous) '' Imaia'' (hypogeous) '' Leucangium'' (hypogeous) '' Fischerula'' (hypogeous) Descri ...

Leucangium
''Leucangium'' is a genus of ascomycete fungi. The genus was circumscribed by French mycologist Lucien Quélet in 1883. Although classification (biology), classified in the Helvellaceae in the past (''e.g.'', in ''Dictionary of the Fungi'', 10th edition, 2008), molecular phylogenetics, molecular analysis indicates it is closely related to the genus ''Fischerula'' and ''Imaia'', and therefore must be placed in the Morchellaceae. The genus includes two species, ''Leucangium ophthalmosporum'' Quél. (the type species, type of the genus) and ''Leucangium carthusianum, L. carthusianum'' (Tul. & C. Tul.) Paol., and both of them produce wikt:sequestrate, sequestrate (fully or partly underground) ascoma, globose to ellipsoidal ascus (inamyloid and eight-spored), and dark olive-colored to grayish green, smooth, fusiform ascospores.
