118 ' GEOLOGICAL AND NATURAL HISTORY SURVEY OF CANADA. 



77. BRYUM, Dill. 



(454.) B. arcticum, Bruch & Schimp. ; Lesq. & James, Mosses of 

 N. America, 224. 



On the summit of Mount Albert, Gaspe Co., Que. ; House Mountain 

 south of Lesser Slave Lake, N.W.T. (Macoun.') Melville Island. 

 (Parry.) Eocky Mountains. (Bourgeau.) Smith's Sound, between 

 lat. 78 82. (Dr. Hayes:) Clavering Island, Upernivik. (FL Gr.) 



(455.) B. erubescens, Kindb. (n. sp.) 



Stems short, scarcely 1 cm. high, loosely tufted. Leaves of the 

 innovations green and small ; stem-leaves few, red-brown, not decur- 

 rent, ovate-lanceolate acuminate, red-margined, not revolute at the 

 entire borders ; areolation pellucid, decelerate, upper cells narrow- 

 rhomboidal or hexagonal ; costa red, more or less excurrent ; inner 

 perichetial leaves smaller, immarginate, slightly sinuolate above with 

 a percurrent costa. Capsule small, regular, pendent, narrow-oblong, 

 constricted below the mouth ; cilia appendiculate ; lid convex, mammil- 

 late ; pedicel thin, pale red, 2-3 cm. long. Spores extraordinarily 

 large, about 0*08 mm. Dioecious. 



This species having the habit of a Webera (W. acuminata or W- 

 polymorpha'), has no affinity to the other Eubrya, found in Canada. The 

 small reddish leaves and the large spores distinguish it at once. It 

 grows mixed with Amblystegium porphyrhizon. 



On the roots of a turned-up tree close to the discharge of Lake 

 Louise, Eocky Mountains (No. 178). August 18th, 1891. (Macoun.) 



(456.) B. haematophyllum, Kindb. (n. sp.) ; Canadian Musci, 

 No. 555. 



Stems short, about 1 cm. high, loosely tufted or solitary. Leaves 

 small, red, densely crowded, not decurrent, ovate or ovate-oblong, 

 acute, indistinctly margined, reflexed at the entire borders ; areolation 

 red, nearly uniform and loose ; costa very broad, not, or very short, 

 excurrent ; perichetial leaves oblong-lanceolate. Capsule (not ripe) 

 regular, pendent, obovate ; lid convex, short-apiculate ; pedicel thin, 

 1-2 cm. long. Spores small. Dioecious. 



This species, probably belonging to the section Eubryum, is peculiar 

 in the thick and broad costa of the red and short leaves. 



On wet rocks in the " Dry Canon " near the discharge of Devil's 

 Lake, Eocky Mountains (No. 104). August 10th, 1890. (Macoun.} 



No. 164, collected in the same locality seems to belong here, but the 

 single unripe capsule has a mammillate lid.
