Pseudoschismatomma is a monotypic fungal genus in the family Roccellaceae.

It contains the single species Pseudoschismatomma rufescens, a corticolous (bark-dwelling), crustose lichen.

This species was first described in 1794 by Christiaan Hendrik Persoon as Opegrapha rufescens.

[2] Pseudoschismatomma was circumscribed in 2014 by Damien Ernst and Anders Tehler, following molecular phylogenetic analysis and revision of the Roccellaceae.

It differs from this species in having a distinct brown true exciple.
