Anomobryum concinnatum is a widespread boreal-temperate species, rarely with capsules, identical to material of the synonym A. leptostomoides in gametophyte features. Specimens assigned to the latter are few and produce erect capsules with highly reduced peristomes. These specimens have been interpreted as fertile specimens of A. concinnatum, a name with priority. Because A. concinnatum is rarely separated from A. julaceum, the distributions of the two in North America are tentative; A. concinnatum is the more widespread.
