Discussion:

Anacolia laevisphaera has stiffly erect leaves that give the plants the appearance of a Campylopus. The only other Central American species in the genus, A. campylopus, also has stiffly erect leaves, but differs from A. laevisphaera in its smaller size, unistratose leaves, centrally located papillae, shorter basal leaf cells, and axillary hairs with elongate rather than globose terminal cells. Central American species of Bartramia differ from A. laevisphaera in having leaves strongly sheathing at base.

Stems red, laxly ascending, not or sparsely branched below, hyalodermis absent, central strand well-developed, moderately to strongly tomentose at base; rhizoids reddish brown, lightly papillose; axillary hairs two-celled, lower cell quadrate, brown, upper cell globose, hyaline. Leaves 3–4 mm long, closely spaced, appressed when dry, erect-spreading when wet, ovate-lanceolate, spreading from the insertion; apex narrowly acuminate; margins coarsely double serrate, revolute above; costae excurrent, with low ridges and toothed at back in upper part of leaf; upper cells bistratose, short-rectangular to subquadrate, firm- and straight-walled, pluripapillose at cell ends, 10–15 x 5 μm, lower cells long short-rectangular to linear, firm and straight-walled, smooth, 17–62 x 5–10 μm, alar cells enlarged and bulging in small group with 3–5 rows of enlarged quadrate cells above. Dioicous. Sporophytes not known from Central America. “Sporophyte terminal or lateral by innovation; seta short, straight, less than 1 cm long, reddish brown; capsule nearly spherical, 2–3 mm in diameter, reddish brown when ripe, rugulose when dry, neck lacking, mouth small; exothecial cells quadrate to polygonal, several rows below the mouth transversely elongated, thicker-walled and darker in color; peristome lacking; lid low convex.
