Pilopogon is characterized by its long, sheathing perichaetial leaves, cylindrical, smooth, estomate capsules, and straight setae. It is gametophytically close to some Campylopus species. But Central American species of Pilopogon have undifferentiated alar cells, and no species of Campylopus has dorsal costal stereids as well as rectangular, thin-walled, hyaline basal cells that continue up the basal margin in V-shaped pattern. The appressed-leaf habit of Pilopogon also occurs in Aongstroemiawhich has shorter setae, non-sheathing perichaetial leaves, and a narrower costa. Dicranodontium has longer upper leaf cells, leaves sharply contracted into long subulae, non-sheathing perichaetial leaves, and entire calyptra. Frahm (1983) has revised the genus.

Plants slender in loose to dense tufts; stems irregularly branched, equally foliate, sparsely radiculose at base, central strand well-developed. Leaves appressed when dry, erect-spreading when wet, lanceolate, subulate-acuminate above; costa broad, with dorsal and ventral stereids, smooth or ribbed at back; upper cells small, thick-walled; basal cells rectangular, thin-walled, frequently hyaline at extreme base and for some distance along the basal margin; alar cells not differentiated.
