cells more distinct; costa less translucent. Hedwigia 32: 245. 1893.— Indi- 

 ana; Illinois; Wisconsin. 



413. Anomodon heteroideus Kindb.— Plants densely tufted, green, 

 finally fuscescent or blackish: stem creeping, subpinnate, much branching 

 and furnished with numerous, small, flagelliform branchlets, densely beset 

 with very small oblong obtuse and nerveless leaves, paraphyllia broad; 

 stem leaves sub-distant, decurrent, appressed when dry, open-erect when 

 moist, from a broadly ovate base, suddenly narrowed to a long subulate or 

 sub-linear acumen, entire, faintly papillose; margins revolute at base; 

 branch leaves more attenuate; cells round oval, marginal basal ones quad- 

 rate; costa vanishing below acumen; dioicous: fruit not found. Mac. Cat. 

 172.— On flat limestone rocks and roots of trees: Ontario and Rocky Moun- 

 tains. 



414. Lescuraa Schimp.— Primary stem obscurely creeping, secondary 

 fertile stems ascending, fasciculately radiculose, pericha;tial branch not 

 radicant: leaves erect-spreading, costate, smooth, sulcate; cells narrowly 

 oval or oblong rhombic, at angles narrowly quadrate: calyptra long, nar- 

 row, sub-tubulose, early deciduous; annulus narrow; teeth confluentin to a 

 basilar membrane, firm, narrowly lanceolate, vermicular verrucose, orange; 

 segments from a narrow membrane, equaling or shorter than teeth, irregu- 

 larly appendiculate, whitish yellow; spores minute.— Synop. Muse. Europ. 



620. 1876. 



415. Lescursea imperfecta C. M. & Kindb.— Tufts loose, green, not 

 shining: stem pinnate, radicant; paraphyllia few: stem-leaves smooth, de- 

 current, often bistriate, from a short ovate base suddenly narrowed into a 

 long subulate or filiform often curved acumen, when dry loosely appressed 

 with a patent acumen, distant and patent-open when moist; basal mar- 

 gins recurved; branch leaves long attenuate; inner cells near the costa ob- 

 long sub-linear, margined sub-quadrate, the others oval-oblong; costa van- 

 ishing in base of acumen; perichastial leaves nerveless; cells sub-linear: cap- 

 sule small, oblong, straight; lid conic, sub-obtuse; peristome double, teeth 

 incurved; cilia short or none, basal membrane indistinct; seta smooth, fine, 

 flexuous: dioicous. Mac. Cat. 170.— On earth and bark at bases of trees: 

 Revelstoke, B. C. 



416. Platygyrium repens ortlioclados Kindb.— Branches elongate, not 

 curved: all basal leaf cells orange; segments linear, not completely free at 

 base, smooth or denticulate at one side, not shorter than teeth. Mac. Cat. 

 172. — On old logs: Ottawa. 



417. Pylaissea pseudo-platygyriuiii Kindb.— Tufts intricate: stem ir- 

 regularly divided, or sub-pinnate; branches thick: leaves crowded, upper 

 glossy green, others finally brown, from ovate-oblong base, long 

 acuminate, acumen sub-filiform, often curved, distinctly denticulate: 

 borders recurved to acumen: cells narrow and confluent except the quad-
