1. Bryhnia NOVAE-ANGLIAE (Sullivant and Lesquereux) Grout 



(Hypnum novae-angliae Sullivant and Lesquereux; Brachythtcium 

 novae-angliae Jaeger and Sauerbeck) 



Plate LXIX 



Widely and loosely matted, bright green outside, dirty green inside, rather 

 rigid: stems prostrate, irregularly sub-pinnately branched, sometimes more or 

 less dendroidal in appearance; branches often indistinctly julaceous; branch- 

 leaves rather loosely imbricate when dry, erect-spreading when moist, broadly 

 ovate, acute to shortly acuminate, concave, decurrent, serrulate, up to 1-1.2 x 

 0.5-0.6 mm, dorsally papillose by reason of the projecting cell-angles, the leaf- 

 apex often twisted about half-around; median leaf-cells about 5-6:1, oblong- 

 hexagonal, somewhat shorter and broader below and at the basal angles; peri- 

 chaetial leaves ovate, abruptly long-acuminate, faintly costate; costa of branch- 

 and stem-leaves reaching to the middle or slightly beyond; stem-leaves similar 

 to the branch-leaves but more broadly triangular-ovate and with more distinct- 

 ly quadrate alar cells, occasionally some inflated, and somewhat excavate: seta 

 ."-hort, very rough, dark castaneous; capsule dark-castaneous, blackish when old, 

 about 4-5:1, reaching about 3.5-4.5 mm in length, oblong, erect, slightly 

 curved; lid conic-acuminate or sub-rostellate; peristome normal; annulus 

 double, large; spores mature in winter. 



On the ground and on stones in swamps and wet, shady places; Europe, 

 Asia, and from eastern Canada to Maryland and Pennsylvania.

{Hypnum graminicolor Bridel; H. Sullivanlii Spruce; 

 Eurhynchium graminicolor Paris) 



Plate LIX 



Small, much more slender than the preceding species, densely to loosely 

 cespitose, pale green, yellowish below: stem.s slender, red, usually not over 1-2 

 cm long, rather irregularly branched with erect branches; branch-leaves reaching 

 about 0.8 x 0.8-0.3 mm, narrowly lance-ovate, long-acuminate, concave, serru- 

 late to the base, marginally refiexed below, the base decurrent, the back strong- 

 ly papillose by reason of the projecting cell-angles, the costa reaching to above 

 the middle; stem-leaves larger, up to 0.8-1.0x0.4-0.5 mm, with a somewhat 

 more slender acumen; median leaf-cells linear-flexuous, incrassate, varying from 

 ■^-8:1, obtuse, the alar sub-quadrate, thin-walled, pellucid; perichaetial leaves 

 cblong, basally sheathing, filiform-acuminate, very faintlv costate: seta about
