and T. urceolatus he states he found "that the areolation of 

 the leaf afforded a very distinct character, that of urceolatus 

 being shorter, more rectangular and above all more incras- 

 sate, that of all forms of T. mnioides being more irregular, 

 more elongated and with thinner walls.*' He further states 

 that the Labrador plants he has seen all belong to mnioides 

 and that possibly we do not have the true urceolatus in 

 America. The specimens collected at Dawson, however, en- 

 tirely agree with European specimens of the latter, the cell 

 characters being just such as pointed out above (622). 



Funaria calcarea Wahl. On bare earth of river bluff just 

 below Dawson. This species is only to be separated from 

 Mediterranean apparently, by the slightly more serrate leaf 

 and shorter point. Leaf-cells above about .036 x .060 mm. 

 Teeth with about 12 lamellae, 4 or 5 rows of transversely 

 elongated cells about mouth of capsule and rough spores up 

 to .025 mm. (629). 



Funaria hygrometrica (L.) Sibth. Lake Marsh and near 

 Dawson (630). 



Funaria hygrometrica arctica Berggrn. Lower Klondike 

 River. The specimens are mostly from 12 to 20 mm. high. 

 Spores up to .024 mm. The spores of hygrometrica run up 

 to .016 or .018 mm. (691).

 Sheep Camp, Dyea Creek (633). 



Philonotis fontana (L.) Brid. Rather common about Lake 

 Lindeman and Lake Bennett (635). 



Conostomum boreale Swartz. Growing in dense cushions 

 on wet rock near Long Lake, between Chilcoot Pass and 

 Lake Lindeman (634). 



Catoscofiium nigritum (Hedw.) Brid. Dawson. In fine 

 fruit about springs, May 7 (636). 



Meesea trichodes (L.) Spruce. {Meesia uliginosa Hedw.)
