L. carthusianum L. ophthalmosporum 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.

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.
