H. subliiteum, E. & E. (in Herb.) 



Stroma effused, mostly elongated to 5 or more centimeters in 

 length and 2 or more cm. wide, about 1 mm. thick, surface cinereous 

 roughened by the projecting, obtusely conical, darker colored ostiola 

 black inside except the layer next the wood, which is pale yellow witl 

 a greenish tint. Perithecia monostichous, ovate, about ^ mm. widf 

 and a little more than that in height, their vertices slightly raising th( 

 surface of the stroma in a pustuliform manner. Asci cylindrical, 75- 

 80 X 6 /i (p. sp.), with a slender base about 40^/i long. Sporidia uni 

 seriate, navicular, 2-nucleate, becoming opake, 10-J 2x4-4^ //. 



On rotten wood, near St. Martinsville, La. (Langlois, 2276). 



H. Morgan!, E. & E. (in Herb.) 



Effused in patches 1-2 cm. long. Perithecia' in a single layer 

 touching each other but hardly confluent, slightly depressed-globose 

 about I mm. diam., connected and covered, except the black, sub 

 hemispherical, broadly perforated ostiolum, by a thin, furfuraceo 

 tomentose, glabrescent, light tawny yellow ci'ust. Asci subcylindrical 

 1 50 X 10-12 /i, with evanescent, filiform paraphyses. Sporidia over 

 lapping-uniseriate, navicular, brown, 35-38 x 10-12 //. . 



On rotten wood, Ohio (Morgan). 



The apices of the perithecia project, rendering the surface of the 

 stroma mammillate. 



H. Ohi^nse, E. & E. (in Herb.) 



Stroma effused for several centimeters and about 2 mm. thick 

 surface uneven, colliculose, umber color. Perithecia ovate, subdis 

 tichous, |-1 mm. broad and 1-1 J mm. high. Ostiola papilliform, um 

 bilicate-collapsing at the apex, and soon hidden by the heaps of olive 

 brown, discharged sporidia. Asci (p. sp.) clavate, 22 x 6 //, with i 

 filiform stipe 30-40 /z long, paraphysate, 8-spored. Sporidia obliquelj 

 uniseriate or biseriate, narrow-elliptical, brown, 4-5 x 2^ fi. 



On rotten wood, Ohio (Morgan, 883 and 965). 



This might perhaps be considered a var. of H. Petersii, but i 

 differs from that species in its effused stroma without any membrana 

 ceous veil, in its larger perithecia and smaller asci and sporidia. Ii 

 both, the color and texture of the stroma is the same — umber coloi 

 paler inside.
