Lecanographaceae is a family of mostly lichens (also some lichenicolous fungi) in the order Arthoniales.

[1] The family was circumscribed in 2014, prompted by a molecular phylogenetic-based restructuring of the Arthoniales.

The ascomata are narrow and furrowed (lirelliform) to rounded, and there is no margin around the thallus.

The excipulum (a layer of sterile tissue that contains the hymenium) is conspicuous, dark brown, usually closed, without a thalline margin.

The cells divide in two equal parts during the spore septation.
