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 with 

 a greenish tint. Perithecia monostichous, ovate, about \ mm. wide 

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

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

 80x6 p. (p. sp.), with a slender base about 40 ju long. Sporidia uni- 

 seriate, navicular, 2-nucleate, becoming opake, 10-12 x4-4| //. 



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

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



Eifused in patches 1-2 cm. long. Perithecia in a single layer, 

 touching each other but hardly confluent, slightly depressed-globose, 

 about | mm. diain., connected and covered, except the black, sub- 

 hemispherical, broadly perforated ostiolum, by a thin, furfuraceo- 

 tomentose, glabrescent, light tawny yellow crust. Asci subcylindrical, 

 1 50 x 10-12 jut, 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. Ohiense, E. & E. (in Herb.) 



Stroma effused for several centimeters and about 2 mm. thick, 

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

 tichous, f-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 /i, with a 

 filiform stipe 30-40 /i long, paraphysate, 8-spored. Sporidia obliquely 

 uniseriate or biseriate, narrow-elliptical, brown, 4.-5 x 2| //. 



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



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

 differs from that species in its effused stroma without any membrana- 

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

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

 paler inside.
