Dermatocarpon miniatum (L.) Mann and D. reticulatum Magn. have vagrant forms with the gross morphology of D. vagans Imsh. Dermatocarpon vagans is not a distinct species. Rather, it is an environmental modification of D. reticulatum. Optimum habitat for vagrant Dermatocarpon in the western United States has the following characteristics: mostly flat, exposed areas with sparse vegetation; thin rocky basalt soils; seasonal shallow ponding; and a climate with hot dry summers and cold winters.
