A NEW Lemanea from Newfoundland. — Lemanea (Sach- 

 eria) borealis. Sexual shoots evenly tufted, slender, 1-3 cm. 

 or more long by 0.25-0.33 mm. in diameter : sterile base 

 0.5-1 cm. long, slender, gradually tapering into the fertile por- 

 tion, the transition very rarely abrupt : antherid zone when 

 young prominently tuberculate with 2-5 antherid papillae, these 

 disappearing in age so that the older shoots are plane : procarp 

 zone usually cylindrical, rarely constricted in the middle, some- 

 times slightly so near the apex, the result being that in age, with 

 the disappearance of the antherid papillae, the shoots are nearly 

 or quite cylindrical, ihe younger and middle-aged ones appear- 

 ing slightly nodose : procarps arising in both the antherid zone 

 and procarp zone, but not quite reaching the middle of the pro- 

 carp zone : carpospores in tufts throughout the entire length of 

 the shoot, not collected at the antherid zones as in L. fucina and 

 its varieties, but not extending so closely to the middle of 

 the procarp zone as in L. fiiiviatilis : carpospores elliptical to 

 oblong, 25-45 a x 18-25 fi : Chantraiisia stage represented only 

 by fragments at season when collected, but threads 18— 2 5// in 

 diameter, cells 35-45 i'- long, often slightly constricted at the 

 septa : plants of a dull green color on drying, the spores some- 

 times showing a tinge of blue, and darkening, but not blackening 

 the shoots : species of a parasitic Chafitransia {C. vio/acea) some- 

 times present on the old shoots.
