Perithecia usually densely crowded, forming a uniform crustaceous 

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

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

 times slightly umbilicate, or without any distinct ostiolum, 500-700 mm. 

 diam., often overrun with brown, creeping hyphse. 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 /i. Paraphyses filiform, branching.

 Lepiospora strigosa, Fckl. Symb. Mycol. p. 144. 

 Lasiosphcsria 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. Ostiolum papilliform-conical or obsolete. Spo- 

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



On damp pine wood, Carolina. 



Pries (S. M. JI, p. 448) say's this species is not easily distinguished 

 from L. canescens, 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. intrickta, Pk. Bull. N. Y. State Mus. Nat. Hist. No. 2, p. 23. 



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

 long, 500-600 /j. 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 //. Sporidia 

 crowded, linear, curved or flexuous, greenish-yellow, 40-65x4^-5 /i.

The perithecia, though small, resemble in shape those of Bom- 

 hardia fasciculata. The minutely papillate ostiolum is often con- 

 cealed bv the tomentum 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. strigosa, 

 L. hispida, L. hirsuta, dec.
