[3][4] It comprises the single species Xanthopsorella texana, a saxicolous (rock-dwelling), squamulose lichen found in the Southern United States and Mexico.

The American lichenologist William Alfred Weber originally named the species Psora texana in 1977.

He collected the type specimen in 1974 from Llano County, Texas in the Guadalupe River canyon along highway 39.

[8] Another taxon proposed for inclusion in the genus, Xanthopsorella llimonae Hertel, Egea & Poelt (1987),[9] has been shown to be synonymous with Glyphopeltis ligustica.

[5] In additional to the type locality in Texas, Xanthopsorella texana has also been recorded in Mexico, including Coahuila, San Luis Potosí, Tamaulipas, and Chiapas.
