Argyrochosma incana has been collected at about 10 localities in the flora area, all within 50 km of the Mexican border. Most herbarium specimens were previously identified as A. limitanea, which is easily distinguished from A. incana by the characteristics given in the key. In addition, all known plants of A. limitanea have 32 spores per sporangium; those of A. incana have 64. Although A. incana shows considerable morphologic and biochemical diversity in Mexico, populations in the United States are relatively uniform.
