48. Cephalozia (Cephaloziella) Sullivantii, (Aust.) Spruce. 



(Jung, divaricata Sulliv. Muse. Allegh. 239; on rotten wood in Can- 

 ada) " quoad habitum et minutiem C. micromerce nostrse persimilis, et 

 cellulis autem pvseminutis et periantbiis ore baud 6-laciniatis longe 

 aliena Cephaloziella vera videretur C. Macounii affinis sed longe minor 

 et stipulifera mihi tamen solum e specimenibus mancis male cognita."

Hab. On rotten elm logs, in swamps at Belleville, Ont. (Macoun.} 



49. Cephalozia (Prionolobus) minima, Austin MSS. 



Dioicous, acrocarpous, green, eflagelliferous, minute. Stems thick, 

 short, simple, capitate, 5 cells in diameter, cortical cells 10-15-seriate. 

 Leaves obovate, broadly ovate or sub-quadrate, sub-carinate, margin 

 quite entire, upper leaves larger, crowded, bifid to ^, segments acute or 

 acutate, broad or narrow. Cells 4-6 sided, very minute, (-016 mm.), 

 trigones wanting, walls moderately thick. Underleaves everywhere 

 present, lower ones entire, broadly subulate ; upper larger, bifid, seg- 

 ments subulate. Bracts 3 pairs, larger than the leaves, subquadrate, 

 bilobed down to J-J, spinulose-dentate with a large tooth near the base 

 on each side ; bracteoles similar, only smaller. Perianth oblong-oval, 

 composed of a single layer of cells, mouth rather wide, sub-entire. 



Male stems more slender, with the antheridia on short postical 

 branches, antheridia 3-4, solitary, very small, roundish.
