Halecania
Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics:  uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores (i.e., surrounded by a transparent coat).
