Dermatocarpon moulinsii is a species of saxicolous (rock-dwelling), foliose lichen in the family Verrucariaceae.

It is distinguished from other members of Dermatocarpon by the presence of rhizines on its underside.

In North America, it occurs as mainly a western montane species.

[1] The lichen was originally described by Camille Montagne in 1843 as a species of Endocarpon.

It is named after French naturalist Charles des Moulins, who collected the type specimen in France.
