Odontoschisma auct. p.p. 

 Sphagnoecetis auct. p.p. 



Plants coarse, light yellow-green to brownish, rarely tinged with red. Stems 

 irregularly branched, the branches dorsi- or ventral-axillary intercalary, leafy or 

 flagelliform, or small-leaved gemmiparous, or short sexual; stem in transverse section 

 with a cortical layer of 1 or 2 rows of smaller thick-walled cells surrounding a 

 medulla of larger cells with thinner walls and trigones. Rhizoids abundant along the 

 ventral side of the stem. Line of leaf insertion oblique, the leaves succubous. Leaves 

 subrectangular to long ovate-truncate, the cells thin-walled and with very large 

 rounded trigones, the cell cavity stellate. L T nderleaves small, broadly ovate, per- 

 sistent, with abundant stalked or sessile slime cells over the margin and surface. 

 Plants dioicous. Male inflorescence whitish, catkin-like, from the ventral side of 

 the stem or from a flagelliform branch, or rarely terminal on the stem, bracteoles 

 present. Female inflorescence on a short dorsal or ventral branch, the bracts and 

 bracteoles in 3 or 4 series, bifid. Perianth long, whitish, 3-keeled above, the mouth 

 contracted, the 3 lobes incised, long and short ciliate. Gemmae 2-celled, at the tips 

 of leafy shoots.

Plants of medium size to robust, coarse, light yellow-green, brown on drying, 

 rarely tinged with red, prostrate in dense mats or among other bryophytes; stems to 

 3 cm or more long, with leaves 2.5-4 mm wide, irregularly branched, the branches 

 intercalary, dorsi-axillary or ventral-axillary, leafy or flagelliform, or small-leaved 

 and gemmiparous at the tip or sexual; in transverse section the stem 10-14 cells 

 across, the cortical layer of 1 or 2 rows of small cells with thick walls, the medulla 

 of larger cells with thinner walls and large trigones. Rhizoids abundant on the 

 ventral side of the stem. Line of leaf insertion oblique. Leaves large, widely spread- 

 ing, subrectangular, to 2 mm long, 1 mm wide, tending to be plane, the margins 

 more or less undulate or crisped, here and there recurved; cells of the upper part
