Leptochidium

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.
