A AJAXUAL OF MOSSES 



America from the Arctic region south to the northern United 

 States. Reported from the adjacent states of New York and 

 Ohio and to be expected from the northern part of our range. 



2. Encalypta streptocarpa Hedwig. 



(E. contorta Lindberg). 



Densely cespitose, dull or yellowish-green ; stems large, 3 

 to 6 or 7 cm. high, branched, densely radiculose at base; leaves 

 rather crowded, spreading, when dry more or less twisted and 

 crisped, large, 5-6 mm. long, oblong-lingulate, sometimes nar- 

 rowed in the middle, undulate, plane-margined, often incurved and 

 sub-cucullate at apex ; costa strong, reddish, ending below 

 apex, dorsally scabrous ; basal leaf-cells hyaline, rectangular, 

 the marginal narrower, often forming a distinct yellowish 

 border of a few rows of cells, upper leaf-cells hexagonal- 

 quadrate, about .015 mm., papillose, incrassate-pellucid, usual- 

 ly regularly seriate ; perichaetial leaves oblong, abruptly long 

 lanceolate-acuminate: seta long, red; capsule long, cylindric, 

 dextrorsely orange-striate, furrowed when dry ; peristome 

 double, the teeth filiform, papillose, articulate, red, the inner 

 peristome of 16 or 32 filiform pale segments half as long as the 

 teeth and adherent to the latter by the broad punctulate basal 

 membrane : lid narrow, long, rostrate, erect ; calyptra very 

 long, cylindric, ^scabrous at the tip of the long and slender 

 beak, extending considerably below the capsule and laciniate 

 at the border ; spores mature in late summer ; dioicous. 



On rocks, walls, earth, etc., usually on calcareous sub- 

 strata, mainly confined to rough country. Europe, Asia, and 

 from Ontario and Virginia to California. Not yet found fruit- 

 ing in North America. Rare in our region. 



Cambria : Cresson. T. P. James. (Porter's Cata- 



logue). 



Famiy VII. GRIMMIACBAE. 



Autoicous or dioicous: cespitose, dark green to blackish: 

 stem mostly without central strand, radiculose only at the 

 base, branches mostly of equal height, leaves often hyaline- 

 pointed, often piliferous, but rarely crispate, when damp more 

 or less spreading, rarely secund, mostly lanceolate, rarely and 

 then only upwards denticulate, towards the apex and at the 

 margin two to several cells thick, sometimes papillose ; costa 

 complete or nearly so, cells small, often sinuate-walled, above 

 mostly rounded-quadrate, towards the base inflated and mostly 

 pellucid, rectangular to elongate, rarely linear throughout the 

 whole leaf: seta rarely shorter than the capsule; capsule most- 

 ly symmetric, globose to cylindric, mostly smooth, often im- 

 mersed or emergent ; annulus present, or none at all ; teeth 16, 

 mostly separate to the insertion, red to orange, papillose, plane,
