|discussion=<p>Distinctive features of Dicranella hilariana include the yellowish seta, erect, smooth capsule, short leaf cells, and leaf tips that are often blunt and crenulate. The species is subject to considerable variation in length and thickness of cell walls, which vary from subquadrate, this often only at the tips of leaves, to long-rectangular or, even linear owing to thickened side walls. The setae are yellow, but with age they take on a dull brownish or even a reddish hue. Various names have been used for plants with short laminal cells, those with somewhat longer, thin-walled cells, and those with cells linear because of thick and often golden walls. As suggested by the large number of synonyms, differences are at best trivial and completely intergradient. The South Carolina report was by H. A. Crum and L. E. Anderson (1981).</p>
