Anomodon rostratus forms dense and thick mats, often very extensive, with clustered stems in a pseudoverticillate branching pattern. This species is distinguishable from congeners in the short branch leaves, ending in a hyaline hair-point several cells long (to 0.2+ mm) and one cell thick. The leaf areolation is also more lax; the basal portion of rhomboid cells extends beyond 1/2 the leaf length. The species fruits frequently and abundantly in North America. Despite this, male gametophytes in North America are extremely scarce, even in populations fruiting profusely. The paucity of male plants is probably the reason why sporophytes are virtually unknown elsewhere.
