Perithecia small (125-150 fi), sphaeroid or elliptical, erumpent, 

 black. Asci subcylindrical, nearly sessile, 55-75 x7-10 ju. Sporidia 

 oblong or subfusiform, slightly colored, 3-5-septate, 20-25 x4-5 ju. 



On dead peduncles of Lycopodiurn clavatum, Adirondack Mts. 

 New York. 



The perithecia are associated with a minutely tufted Clado* 

 xporium. Some of them are laterally compressed. The sporidia are 

 much narrower than in L. Crepini and L. Marcyensis.

Perithecia mostly hypophyllous, gregarious, buried, covered by 

 the epidermis, globose or subdepressed, broadly perforated above, 

 black, 100-150 p. diam. Asci cylindrical or elongated-subclavate, 

 sessile, 8-spored, 70-75x13-14 ft. Sporidia 2- or partly 3-seriate, 

 oblong, obtuse, slightly curved, 3-septate, yellowish, 20-26 x 7-10 pu 

 Paraphyses filiform.

L. polaris, Sacc. SylL II, p. 83, (Sphasria No. 8, Th. Fries in 

 Hedw. 1881, p. 59). 



Perithecia small, immersed, black. Asci cylindric-clavate, with 

 abundant branching paraphyses, 4-spored. Sporidia uniseriate, oblong, 

 obtuse, 3-septate, somewhat constricted at the septa, especially the 

 middle one, cells 1-2-nucleate, obscurely clouded, 28-32x9-10 ji.

We have reluctantly accepted this as a genus distinct from Lepto* 

 xphceria, from which it differs only in its permanently hyaline spo- 

 ridia. Practically it makes little difference whether these hyaline* 

 spored species are recognized under a separate generic name, or 

 considered a section or subgenus of Leptosphceria. In either case
