Perithecia scattered or gregarious, superficial, spherical, clothed 

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

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

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

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

 3-4 ju. 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 [i thick, often imperfectly toothed towards their extremities. 

 Ostiola obtuse, strongly 4-ribbed. Asci 170-200 x 18-20 fi (p. sp. 120- 

 150 ju 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 p., ends rounded and obtuse.

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



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

 coming ovate-conical, j-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 perithecia forming a loosely-felted, pilose sub- 

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

 that clothe the perithecia. Asci subcylindrical, 150-200 x 8 /i, with 

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

 line and vermiform-cylindrical, nucleate, 35 x 4 jjl, 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 ^e), curved
