Species Description - Plants small to medium-sized, mostly soft but sometimes ± stiff, in dull, mostly pale green, sometimes black- or purple-tinged, often large, epiphytic colonies; stems to ca. 7 cm long, but often only ca. 3 cm, freely and irregularly to pinnately branched, the branches simple to irregularly bipinnate, mostly ca. 1 cm long, but to ca. 5 cm at times, complanate-foliate. Branch and stem leaves scarcely differentiated in structure but stem leaves often somewhat smaller, less complanate, and soon eroded leaving stem ± naked, branch leaves strongly complanate, mostly wide-spreading, asymmetric, curved oblong-ligulate, broadly rounded to truncate, undulate dry or moist, clasping the branches, cordate to small-auriculate, 1.4-2.5 x 0.5-0.8 mm; margins serrulate-crenulate at apex, distantly serrulate below, inflexed on one side below; costa single, slender, ending ca. 3/4 the leaf length; cells irregularly long-hexagonal, 10-25 x 5-8 µm, firm- to thick-walled, ± porose, becoming shorter in a large band across the leaf apex, these short-rectangular to subquadrate or rarely oblate, becoming more elongate and more conspicuously porose toward the insertion. Autoicous and synoicous. Perichaetial ramenta longer than the perichaetial leaves and emerging from them and overtopping the capsules, loriform, to 3 mm long. Setae ca. 0.25 mm long; capsules immersed (in ramenta), ca. 1.5 mm long. Calyptrae mitrate-campanulate.
