|discussion=<p><i>Grimmia muehlenbeckii</i> is closely related to <i>G. trichophylla</i>, and in the past it was frequently regarded as a subspecies or variety of that taxon. H. Deguchi (1978) treated it as a distinct species, followed by A. J. E. Smith (1992). Greven agrees with those treatments. He has seen many specimens that are remarkably uniform and easy to distinguish from <i>G. trichophylla</i> by their small, globose, shiny, dark brown capsules with purple, entire peristome teeth. In contrast, the capsules in <i>G. trichophylla</i> are oblong-ovoid, larger and longer than in <i>G. muehlenbeckii</i>, dull, yellowish brown, and the peristome teeth are orange and cleft. The gametophyte differs from that of <i>G. trichophylla</i> by its blackish green tufts, angled costa with blunt wings protruding on the abaxial side, and ovate-lanceolate leaves with stout, denticulate awns that are often decurrent.</p>
