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 hyphge. xlsci fusoid-clavate, 

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

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

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

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

Lasiosphtzria strigosa, Sacc. SyH. 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 fi. 



On damp pine wood, Carolina. 



Fries (S. M. II, p. 448) says 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. intricata, Pk. Bull. N. Y. State Mus. Nat. Hist, No. 2, p. 23. 



Perithecia scattered or crowded, somewliat elongated, 650-900 [x 

 long, 500-600 tt 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 pt. Sporidia 

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



On decaying wood and leaves, in damp places, Sandlake, N. Y. 

 (Peck). 



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

 bardia fasciculata. The minutely papillate ostiolum is often con- 

 cealed by 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, &c.
