Discussion:

In its typical form Campylopus surinamensis is recognized by its short basal rosette of spreading leaves that abruptly give way to an elongate stem with tightly appressed leaves crowned by a comal tuft of spreading leaves. Frequently the comal leaves are hyaline hair-pointed. The leaves on a single plant can be exceedingly variable. When keying plants, leaves from stems bearing appressed leaves should be examined. In these leaves the alar cells are poorly developed, the costa excurrent, and the leaf margins distictly serrate. Important microscopic features of this species include its thin-walled, non-porose basal leaf cells and ridged costa that in cross section has ventral hyalocysts usually smaller than the guide cells. This last feature separates C. surinamensis from all other species except C. flexuosus, C. zygodonticarpus, C. oerstedianus, C. lamprodictyon, C. angustiretis, and C. pilifer.

Frahm's (1991a) report of this species from Honduras is based on a collection from British Honduras" (= Belize).

Plants medium sized, forming loose tufts, yellowish to bright green; stems variously tomentose, to 3.5 cm long. Leaves typically spreading at base, becoming abruptly appressed to the stem, then crowded and spreading in apical comal tufts, exceedingly variable in shape: basal leaves oblong-ovate, acute, to 3 mm long, concave; margins inflexed, serrate at apex, not bordered by elongate cells; upper leaves linear-lanceolate, concave, acute, to 2–4 mm long, serrate or entire, not bordered by elongate cells; costa percurrent in basal leaves, excurrent in others, at times more or less hyaline, ridged on back and dorsally serrate above, frequently spurred, in cross section with ventral hyalocysts equal to or smaller than the guide cells, dorsal stereids well developed; upper cells short to long rhomboidal, firm-walled not pitted, median cells rhomboidal to rectangular, firm-walled, basal cells above the alar cells quadrate to rectangular, thin walled; alar cells of basal leaves inflated, brown, well-developed, alar cells of other leaves poorly developed, hyaline. Perichaetial leaves frequently hyaline hair-tipped. Sporophytes unknown in Central America.
