Leptochidium is a genus of lichen-forming fungi in the family Massalongiaceae. It has two species:
Leptochidium albociliatum (Desm.) M.Choisy (1952)
Leptochidium crenatulum (Nyl.) P.M.Jørg. (2006)
The genus was circumscribed by French lichenologist Maurice Choisy in 1952. Leptochidium remained monotypic until 2006, when Per Magnus Jørgensen transferred into it a species originally named Leptogium rivulare var. crenatulum by William Nylander.
