Thalli smallish to medium-sized, in crowded, overlying patches; bright green to deep green, areolate, air pores tiny, margins dark red, scalloped or undulating; when dry, thallus margins incurved or raised and clasped together. Branches simple or once/twice pseudodichoto-mously furcate, narrowly to moderately divergent, broadly ovate or oblong, (3-)5-10(-12) mm long, 2.5^1.8 mm wide, 1100-2000 µm thick medianly, in section ± twice wider than thick, apex emarginate; groove deep along entire midline, except where interrupted by gametangia, thallus margins rather obtuse to acute; flanks steep to sloping obliquely, deep purple; ventral face rounded to flattish, green. Scales lateral, covering flanks, obliquely triangular, dark red, to almost black, shiny, in apical scales basal part hyaline, closely imbricate, 1250-1375 µm long, margins entire, sometimes crenate or shortly toothed toward base of distal side, 1075-1200 µm wide across base, apex projecting up to 375 µm above thallus margins, oil cells absent. Dorsal epidermal cells unistratose, hyaline, polygonal, (22.5-)37.5-45.0(-52.0) x 27.5-37.5 (^47.5) µm; air pores slightly raised, small, simple, 5-10 µm wide, 4- or 5(6)-sided, stellate, surrounded by one ring of 4 or 5, rarely 6, small, bluntly wedge-shaped cells, radial walls slightly thickened, partly overlying, or occasionally adjoining larger polygonal cells. Assimilation tissue 400-600 µm thick, air chambers empty, in one storey, bounding walls chlorophyllose, unistratose; storage tissue occupying ventral part of thallus, composed of rounded or angular cells, ± 50 µm wide; oil cells absent. Monoicous. Antheridia in row along midline, proximal to archegonia, immersed, necks hyaline, cylindrical, protruding above dorsal surface of thallus. Archegonia in median row, in flask-shaped cavities, partly sunken into thallus. Involucre ridged, enclosing archegonial groups, ± 600 µm high, irregular, fleshy, crest-like, tinged reddish on top around openings of archegonial necks, these long and turning purple with age. 25. Sporophytes ventrally partly sunken into thallus, dorsally bulging on either side of central crest, capsule globose, wall thin, delicate, lacking thickening bands. Spores (108-)110-115(-125) jum diam., triangular-globular, black, opaque, anisopolar, with ornamentation different on two faces; distal face with 6 or 7 large, central alveoli, up to 30 µm wide, smaller toward margin, generally with a nodule and thin radiating ridges in middle of each, alveolar walls thick; proximal face with triradiate mark distinct, 3 facets with incomplete alveoli, walls irregular, sometimes rather indistinct, wing ± 5 µm wide, entire.
