Platygramme is a genus of lichen-forming fungi in the family Graphidaceae consisting of about 30 species.

[1] The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874.

[2] Several features characterise the genus Platygramme: the brown ascospores, an inspersed hymenium, and lirellate fruiting bodies in which some of the tips of the exciple are carbonised and form lamellae (plates).

[3] As of March 2023[update], Species Fungorum (as listed in the Catalogue of Life) accepts 27 species of Platygramme.
