|discussion=<p><i>Dicranella</i> grevilleana is scarcely distinct from <i>D. schreberiana</i>. In its best expression, its leaves are mostly entire, with cells only about 6 µm wide, and capsules faintly or rarely distinctly striate when dry and empty. <i>Dicranella schreberiana</i>, in a narrow sense, has leaves usually denticulate above, with broader cells, 8–14 µm wide, and smooth capsules. The differences, small and scarcely constant, can perhaps be related to relative environmental wetness. <i>Dicranella schreberiana</i> <i></i>var.<i> robusta</i> also seems no more than an ecotype of particularly wet habitats. It is larger and has serrated leaf margins and particularly broad leaf cells. A large expression of the species greatly resembles <i>D. palustris</i>, which has leaves entire except for crenulations at the extreme apex. Literature reports among the states cited were: New Jersey and Oregon (E. Lawton 1971), Massachusetts (F. J. Hilferty 1960), and Utah (S. Flowers 1973).</p>
