wood, finally more compact and interwoven. Peritbecia 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 perithecia are often found broken, leaving 

 little pits in the subiculum. Sporidia {sec. Cooke, Grev. XV. p. 82) 

 30-32 II long. 



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



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

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

 their loose, hair_v covering. 



L. hispida. (Tode,) 



Sphttria hispida, Tode. Fungi Meckl, II, p. 17. 

 Lasiosphixria hispida, Fckl. Symb. p. 147. 

 Bxsicc. Fckl. F. Rh. 949, 2039. — Thum. M. U. 1745. — Sydow M. March. 1482. 



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

 with a large, subconical, often compressed or deeply quadrisulcate 

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

 hairs, which are longer below, and pass gradually into a loosely intei-- 

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

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

 stipe, 150-160 x 14-16 p.. Sporidia vermiform-cylindrical, curved be- 

 low, becoming brown, and 6-7 -septate, 55-62x5-7 ji. 



On wood of Juglans nigra, North Carolina (Curtis). 



Winter makes the sporidia 70-80 x 7-8 //. We cannot find any 

 in specimens issued liy Thiimen & Sydow over 62 or 63 n long, (mostly 

 between 55 and 60 fi). 



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

 ithecia. L. hirsuta, L. Rhacodium, and L. hispida 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. 



L. orth«tricha, (B. & C.) 



Sphxria orUwtricha, B. & C. Grev. IV, p. lo8. 

 Lasiosphtriia orthotricha, Sacc. Syll. 3551. 



Perithecia gregarious but scarcely crowded, clothed with long, 

 straight, acute hairs. Sporidia linear, with 6 septa, 50-62 /z long, 

 dark brown, sometimes slightly curved. 



On decayed Nyssa, South Carolina. 



The characters given do not separate^ this accurately from L. 

 hispida, (Tode).
