Perithecia usually densely crowded, forming a uniform crustacemis 

 layer, spherical or a little narrowed below, black, lusterless, rough. 

 carbonaceous and brittle, with a small, papillifbrm ostiolum or some- 

 times slio-htlv umbilicate. or without anv distinct ostiolum, 500-700 mm.

diam., often overrun with brown, creeping hyphae. Asci fusoid-clavate, 

 slightly attenuated above and narrowed below into a long stipe-like 

 base, 8-spored, 130-160 x 9-10| //. Sporidia imperfectly biseriate. 

 cylindrical, bent below, continuous or indistinctly uniseptate, hyaline, 

 19-22 x 4 //. Paraphyses filiform, branching.

 La sio splicer ia strigosa, Sacc. Syll. 3574. 



Perithecia crowded, rather large. subglobose or subovate, of a 

 dirty black color, substance tough, clothed with long, stiff, divergent. 

 hoary, bristle-like hairs. < )stiolum papilliform-conical or obsolete. Spo- 

 ridia elongated, somewhat curved, pale brown, continuous, 40x5 //. 



On clamp pine wood, Carolina. 



Fries (S. M. II, p. 448) says this species is not easily distinguished 

 from L. canewHx, but gives these distinctive characters: Perithecia 

 a little larger, tough, covered all over with long, rigid, divergent 

 bristles, much crowded, fibres of the subiculum not becoming crus- 

 taceous-concrescent. 



L. intricata, Pk. Bull. X. Y. State Mus. Nat. Hist. No. 2, p. 23. 



Perithecia scattered or crowded, somewhat elongated, 650-900 // 

 long, 500-600 /z broad, generally narrowed towards the base, obtuse, 

 subfragile, tomentose-hairy, brown or blackish-brown : subiculum very 

 thin or none. Asci slender, elongated, 150-200 x 10-12 p. Sporidia 

 crowded, linear, curved or flexuous, greenish-yellow, 40-65 x4|-5 <i.

The perithecia, though small, resemble in shape those of 

 bardia fasciculata. The minutely papillate ostiolum is often con- 

 cealed by the toinentuni of the perithecia ; this is composed of intri- 

 cate, matted, slender, septate, brown filaments, which, by their soft. 

 tomentose character, readily distinguish this species from L. x 

 L. hispida, L. hirsuta, &c.
