Leucangium is a genus of ascomycete fungi.[1] The genus was circumscribed by French mycologist Lucien Quélet in 1883.[2] Although classified in the Helvellaceae in the past (e.g., in Dictionary of the Fungi, 10th edition, 2008),[3] molecular analysis indicates it is closely related to the genus Fischerula and Imaia, and therefore must be placed in the Morchellaceae.[4] The genus includes two species, Leucangium ophthalmosporum Quél. (the type of the genus) and L. carthusianum (Tul. & C. Tul.) Paol., and both of them produce sequestrate (fully or partly underground) ascoma, globose to ellipsoidal ascus (inamyloid and eight-spored), and dark olive-colored to grayish green, smooth, fusiform ascospores.[5]
