|discussion=<p><i>Argyrochosma fendleri</i> is occasionally confused with <i>A. limitanea</i>, which can have slightly flexuous rachises and pinna costae. All <i>A. limitanea</i> specimens with slightly flexuous rachises and costae have 32 spores per sporangium, whereas specimens of <i>A. fendleri</i> consistently have 64. This southern Rocky Mountain species is the only member of the genus that is found on acidic substrates such as granite.</p>
