ichaetial leaves from an oblong sheathing base constricted into a rough 

 subula; costa narrower Pedicel pale, at last twisted to the left above when 

 dry. Capsule and peristome as in D. fuscescens. 



Newfoundland: Leading Pickles and Hermitage Bay {Rev. A. C. 

 Waghorne 1893 and 1895). 



Closely allied to D. fuscescens, Turn., to which it might be subordinated 

 as a subspecies, but nevertheless easily distinguished by the leaves more 

 strongly serrate, very rough on the back, less narrowly subulate and the 

 nerve thicker and broader. 



DiCRANUM suBFULvuM R. and C. 



Loosely cespitose, dark green, filled with earth below. Stems erect, 

 1-2 cm high, simple or sparingly braached little radiculose. Leaves erecto- 

 patent, fiexuous. crisped when dry, narrowly lanceolate, acuminate-subulate, 

 subula canaliculate, subentire or minutely denticulate at apex; costa strong, 

 very broad, about half width of leaf base, smooth or nearly so at back; cells 

 very small, opaque, quadrate, scarcely papillose, somewhat larger and quad- 

 rate or short rectangular below, all very chlorophyllose, the alar lax, 

 enlarged, quadrate or subhexagonal, pellucid, yellowish, brownish or sub- 

 hyaline. Flowers and fruit unknown. 



Distinguished from D fulviwi Hook., by the stems not fiexuous, the 

 leaves not tufted, nearly entire, the costa broader, smooth or only very 

 slightly papillose on the back and the supra-alar cells chlorophyllose, 

 scarcely distmct from the others. 



FissiDENS DEciPiENS DcNot var. WiNONENSE R. and C. 



Differs from the type by its smaller size, the smaller and narrower 

 leaves with the pellucid border most often indistinct, and the less opaque 

 areolation. 



Minnesota: Winona (/ M. Holzinger, Mosses of Mi7inesota, No. 6). 



Trichostomum indigens R. and C. 



Very small, gregarious, dirty-green. Stems scarcely 1-2 mm. high. 

 Leaves patent subcirrate when dry, i. 25-1. 75 mm. long, oblong-lingulate, 

 obtuse, apiculate or subacute, margins revolute below, plane above, very 

 minutely crenulate by the projection of the papillae; costa stout, percurrent 

 or vanishing just below the apex; cells minute, rotundate or subquadrate, 

 densely papillose, becoming gradually larger, obloug, rectangular, pellucid 

 ^ and smooth towards the base. Perichaetial leaves from an oblong and 

 loosely recticulate base, linear-lingulate, obtuse or mucronate. Pedicel thin, 

 reddish, paler above 4-6 mm. long, slightly twisted to the left under the 

 •capsule when dry. Ca[)sule small, erect oblong-cylindrical chestnut-colored, 

 about I mm. long. Lid unknown. Annulus simple, teeth of the peristome 

 purple, slightly twisting, on a narrower basilar membrane, segments fili- 

 form, minutely granulose. marked with a longitudinal line, articulate, 

 slightly nodose and partly connected in the lower part. Probably dioicous 

 {male flowers unseen).
