Plants in crowded stands, green; shoots medium-sized in male plants, up to 10 mm long, 1.4-2.2 mm high, 2.8-3.5 mm wide; female plants rather larger, 10-15 mm long, 2.0-2.5 mm high, 3.3-4.5 mm wide, simple or once/twice furcate, segments moderately to widely divergent, apically 2-7 mm long. Stems prostrate, slightly or not tapering proximally, dorsally chlorophyllose, ventrally usually purple, plano-convex in cross section, in male plants apically up to 450 micro meter (10 cell rows) high, 500 micro meter wide, basally 310-350 x 500-550 µm; female plants apically ±500 µm (10-12 cell rows) high, 650 µm wide, basally ±450 x 600 µm. Rhizoids purple, 12.5-20.0 µm wide. Leaves overlapping, widely spreading, succubously inserted smaller apically but soon enlarging, oblong to obovate, sometimes slightly notched above, lobes equal in size or not in male plants, 1300-2125 x 1100-1925 µm, when sides not parallel narrower below, 1000-1300 µm wide; in female plants mostly larger, 1550-2750 x 1550-2575 µm, below 1075-1750 µm; margins generally almost entire, papillae if present, few, only 1 or 2. Leaf cells thin-walled, in male and female plants quite similar, at upper margins subquadrate to rectangular across, 20.0-42.5 x 27.5-40.0(-57.5) µm, at lateral margins long-rectangular, 65-75 x 20.0-37.5 µm; upper laminal cells 5- or 6-sided, 35-50 x 40.0-47.5 µm; middle laminal cells 50-85 x 37.5-62.5 µm; basal cells 62.5-82.5 x 42.5-50.0 µm. Oil bodies 7-12 per cell, spherical to ovoid, up to 5 µm diam., glistening, homogeneous; chloroplasts numerous, ±5 µm diam. Dioicous. Antheridia dorsal on stem, in 1 or 2 rows, short-stalked, globose or ovoid, 220-250 µm diam., each shielded by a perigonial bract, irregular in shape, 370-450 x 200-300 µm, sometimes 2 adjacent ones joined together, margins mostly without papillae, cells in interior 4- or 5-sided, 50-75 x 27.5-37.5 µm. Archegonia in 1 or 2 rows along stem, naked; sometimes 2 in acropetal sequence or 2 adjacent on a branch becoming fertilised. Pseudoperianth near apex to rather more proximal, campanulate, projecting up to 800 µm above leaves, raised on a short stalk, then widely flaring above, 1625-2250 µm long, 2000-3125 µm wide across mouth, margin undulating or sometimes sparsely and shallowly lobed, very rarely with some angular projections, occasional vertically split along side, lateral outgrowths quite common; cells at margin and immediately below comparable in shape and size to those of leaves, but larger at ± midlength, 100-165 x 32.5-50.0 µm, and at base, 175-195 x 75-80 µm. Capsules globose, ±850 µm diam., wall bistratose, cells in inner layer irregularly shaped, some trapezoidal, others triangular or rectangular, 35.0-42.5 x 17.5-37.5 µm, each cell wall with (1)2 or 3 dark brown, nodular and occasionally semi-annular thickenings. Seta 2.9-4.0 mm long, 290-300 x 240 µm in transverse section, 5 or 6 cells across. Spores golden brown to darker brown, hemispherical, 37.5-55.0 µm diam., including lamellae projecting at margin; distal face convex, with 6-8 irregularly branching and sometimes poorly developed lamellae, ±5 µm high and 5-10 µm apart running across face, a few parallel to each other, others in different directions, occasionally anastomosing and forming some complete or incomplete areolae, rarely with a central tubercle, s surface between lamellae highly uneven, granular or mostly coarsely striated; proximal face lacking triradiate mark, flat, covered with irregularly shaped papillae and fine granules in between as well as marginally, up to 20 ‘spines’ projecting around spore periphery, few of them joined by sections of incomplete wing. Elaters yellow, 75.0-157.5 x 7.5-10.0 µm, tapering to the tips or not, smooth, entirely 2-spiral or 3-spiral, often partly 2-spiral and partly 3-spiral, rarely branched. From: Perold, SM. 1999.

Male plants bearing fairly large, somewhat spaced perigonial bracts shielding antheridia; leaves generally with few (1 or 2) or no papillae at margins and with 7-12 oil bodies per median cell; inner capsule wall with ± half the cells per field having semi-annular thickening bands; distal spore face frequently with poorly developed lamellae, surface between them highly uneven and often coarsely striated; perispore at spore periphery absent or very incomplete; elaters always well-formed, (50.0-)75.0-157.5 µm long with strongly developed spiral bands.
