Perithecia scattered or gregarious, superficial, spherical, clothed 

 with a thin, white, closely adnate, felt-like coat, except the black, 

 papilliform ostiolum, 400-500 // diain. Asci, long clavate-fusoid, with 

 a long stipe. 8-spored, 140-200x12-17 //. Sporidia irregularly 

 arranged, vermiform-cylindrical, mostly curved, continuous, 35-53 x 

 3-4 p. Paraphyses slender, conglutinated. 



Common on rotten wood. 



L. stiipea, E. & E. Bull. Wash. Coll. I, p. 4. (Plate 19) 



Perithecia superficial, gregarious, ovate, about 1 mm. high, densely 

 clothed with dull brown or tow-colored, continuous hairs 200 /j. long 

 and 5-6 /JL thick, often imperfectly toothed towards their extremities. 

 Ostiola obtuse, strongly 4-ribbed. Asci 170-200x18-20 JL (p. sp. 120- 

 150 fj. long), broadest in the middle, attenuated above and contracted 

 into a stipe-like base. Paraphyses abundant, stout, granular, eva- 

 nescent. Sporidia overlapping and crowded subbiseriate, cylindrical, 

 curved, obtuse, granular with a large nucleus in the center, pale brown, 

 34-38 x 8-11 ])., ends rounded and obtuse.

 L. Newfieldiana, E. & E. (in Herb.) 



Perithecia gregarious, superficial, at first depressed-globose, be- 

 coming ovate-conical, |-1 mm. high and ^-| mm. broad, clothed (more 

 densely below) with soft, spreading, brown, septate hairs; similar 

 hairs, more or less branched and loosely interwoven, overspread the 

 matrix between the peritheeia forming a loosely-felted, pilose sub- 

 iculum, which finally disappears more or less, as also do the hairs 

 that clothe the perithecia. Asci siibcylindrical, 150-200 x S //. with 

 abundant paraphyses. Sporidia uniseriate, not crowded, at first hya- 

 line and vermiform-cylindrical, nucleate, 35x4//, with a short, horn- 

 like appendage at each end, the upper end finally enlarging to a 

 narrow-elliptical, brown head 12-14x5-7 //, with a short (7 //), curved
