wood, finally more compact and interwoven, Perithecia ovate-conical. 

 rugulose, black or brown, confluent with the ostiolum, and clothed 

 with numerous long, divergent, black, loose (not rigid) hairs. At a 

 more advanced stage the pcrithecia are often found broken, leaving 

 little pits in the subiculum. Sporidia (sec. Cooke, Grev. XY. p. 82) 

 30-32 // long. 



On rotten wood, Bethlehem, Pa. (Schweinitz). 



Allied to Z. Rhacodium. Differing principally (sec. Schw.) in 

 the loose surface of the subiculum, the shape of the perithecia, and 

 their loose, hairy covering.

Perithecia mostly closely gregarious, ovate-globose, \ mm. cliam., 

 with a large, subconical, often compressed or deeply quadrisulcate 

 ostiolum, clothed with spreading, brownish-black, scattering, bristle-like 

 hairs, which are longer below. ;md pass gradually into a loose!} 7 inter- 

 woven subiculum of branched, septate, creeping hyphae forming a more 

 or less distinct layer on the matrix. Asci cylindrical, with a short 

 stipe. 1 50-160 x 14-16 a. Sporidia vermiform-cylindrical, curved be- 

 low, becoming brown, and (>-7-septate, 55-62x5-7 //. 



On wood of Juglans itiyra. North Carolina (Curtis). 



Winter makes the sporidia 70-80x7-8 ,. We cannot h'jid any 

 in specimens issued by Thiimen <V Sydow over 62 or 63 ti long, (mostly 

 between 55 and 60 //). 



This seems to differ from L. Jiirsuta principally in its bristly per 

 ithecia. L. hirsuta. L. Rhacodium, and L. lixjtiila are very closely 

 allied. Fries (in S. M. II, p. 450), expresses some doubt as to whether 

 they are specifically distinct, or at least, says that it is difficult to sep- 

 arate them.

Perithecia gregarious but scarcely crowded, clothed with long, 

 straight, acute hairs. Sporidia linear, with 6 septa. 50-62 t u long, 

 dark brown, sometimes sliffhtlv curved.
