Sporidia oblong, obtuse at each end, 3-septatc, constricted at the septa, 

 yellow, 12-15x4-5J> 



Not rare around Bethlehem, Pa. (sec. Schw.). 



Dr. Winter states that the sporidia have one or both the middle 

 cells divided by a longitudinal septum, and that the species can not, 

 therefore, belong in Melanomma.

Perithecia scattered, superficial, or subgregarious, at first globose, 

 soon collapsing to concave or cup-shaped, 250-300 p. diam., minutely 

 rugulose, black. Ostiolum papilliform, minute. Texture of the peri- 

 thecia rather soft, parenchymatous, nearly black. Asci cylindrical, 

 attenuate-stipitate, rounded and thickened at the apex, 110-115 x 10 //, 

 with filiform paraphyses, 8-spored. Sporidia obliquely uniseriate. 

 oblong-elliptical, 18-24x6-7 //, rather obtuse at the ends, 3-septate 

 and constricted at the septa, sparingly muriform, olivaceous, with the 

 extreme cells paler.

Teich. muricata. E. & E. Bull. Wash. Coll. vol. I, p. 5. 



Perithecia superficial, hemispherical, \-\ mm. diam., scattered or 

 subgregarious, olivaceous when fresh, dull black and collapsing above 

 when dry, muricately roughened, and often obscurely radiate-sulcate 

 around the prominent and very slightly compressed ostiolum. Asci 

 125x15 IJL, very evanescent, with abundant, stout, granular paraphyses 

 2J_3 fjt thick. Sporidia oblong-elliptical, 18-25x10-11 /*, 3-septate. 

 and at length muriform and brown.
