|discussion=<p>L. E. Anderson and V. S. Bryan (1958) stated that Ditrichum schimperi is not uncommon from Vancouver Island and south through the Coastal Ranges to Yosemite Valley. This is the only Ditrichum species along the west coast of North America with large and roughened papillose spores. Ditrichum pallidum from the eastern and southern United States also has large, roughly papillose spores of similar size, but differs in peristome characters. The peristome of D. schimperi is finely papillose, rather than spinose- or spiculose-papillose, is reduced in size, and is irregularly perforate proximally.</p>
