The Fissurinaceae are a family of lichen-forming fungi in the order Graphidales.

History
Using molecular data (partial DNA sequencing) in 2012, of fungi in the Graphidaceae family in the Ostropales order. The results showed that Graphidaceae and Thelotremataceae were non-monophyletic and consequently Thelotremataceae was included in Graphidaceae as a synonym. Graphidaceae also included the subfamilies Fissurinoideae and Graphidoideae.

Three subfamilies were then recognized in the Graphidaceae family, Fissurinoideae, Graphidoideae  and Redonographoideae.

However, Kraichak et al. in 2018, ranked Graphidales as a separate order based on a temporal approach, and accepted five separate families; Diploschistaceae, Fissurinaceae, Gomphillaceae, Graphidaceae and Thelotremataceae.
