Discussion

Campylium laxifolium differs from C. protensum and C. stellatum in being autoicous and having erect or at least less distinctly spreading leaves that are more ovate and gradually narrowed toward the apex. The species is slightly smaller than C. longicuspis and has more weakly concave, more broadly ovate leaves without differentiated acumina. Campylium laxifolium is known from only three localities in North America, but because it was recently described it can be assumed to be more widespread.
