Sphenolobus sp nov Plants in mats close to the soil, on earth or forest debris, to 3, occasionally to 5 mm long, bent. Dioecous. Leaves approximate to overlapping, somewhat secund. Bifid, broadest about middle; .25 to .3 mm long when mature, by .3, 5mm to .38 mm broad. Lobes obtuse to subacute, sinus open, subcute to lunate. usually subacute. Leaves somewhat obliquely inserted, and secund. Stem with numerous dirty hyaline rhizoids. Underleaves none, except rarely one between the bracts. Cell walls firm, but without trigones, chlorophyll showing up rather plainly. Surface papillose, the papillae showing on both surface (looking down thro microscope) and on edge or surface when folded. Variable in size, shape and arrangement, averaging around 18 mic. Border cells with tendency to be quadrate. Very little larger in size below. Antheridial bracts somewhat similar to leaves, but a little larger, and more saccate, the antherids single in the bracts, and large for the size of the plant, averaging 130 mic. Second pair of bracts, a little larger than leaves, but otherwise similar. Bracts variable 2 to 3 fid, decidedly larger than leaves, sharp pointed to apiculate. Perianth cylindrical to near top, where slightly or more contracted, into short plicae. Avg .14 mm long by .8 mm broad. Teeth numerous and coarse, and variable, from 1 to 5 celled in a single row, or much broader at base, frequently cut into mouth of perianth. Dioecous, antheridial bracts terminal on all examined. Young shoots with smaller and more distant leaves, more acute. Gemmae rare, angular, reddish, irregular in shape, from irregular round to irregular angular. Gemmae deforming tips of upper leaves. Avg 13 mic. (Note, lengths of leaves should be .25 to .3 mm long by .35 to .38 mm broad, shifting the decimal point. This seems to cover the common variations. Type 3864, on forest floor, at Nordegg, Pine Forests. (Alberta) where not rare
