often 2-6 mm. long and so elevated in the center as to become conical. 

 Rather rare on dead stems of Smilax rotundifolia, Salem, N. C. 

 Sporidia (sec. Cke. Grev. XIII, p. 37) allantoid, 12-14 fi long. 



D. subferruginea, B. & Rav. in Rav. Fungi Car. IV, No. 44. 



Exsicc. EH. & Evrht. N. A. F. 2d Ser. 1558. 



Stromata scattered or subseriately confluent, conical from a sub- 

 orbicular base. 1-3 mm. diam., black on the outside, composed inside 

 of the scarcely altered substance of the bark, the apex splitting the 

 epidermis in a sublaciniate manner, but scarcely raising it into pus- 

 tules. Perithecia 8-20 in a stroma, small (about 200 jm diam.), brown, 

 buried in the bottom of the stroma. Ostiola short-cylindrical or elon- 

 gated, (50-250 jul long), smooth at the apex. Asci not well made out. 

 Sporidia (free spores) allantoid, nearly hyaline, 5-6xl-l| fi, only 

 slightly curved. 



On bark of dead oak, South Carolina (Ravenel). 



The stroma is entirely wanting below. 



D. Ceanothi, Cke. & Hark. Grev. XIII, p. 17. 



Stromata wait-like, innate-erumpent, black, round, closely sur- 

 rounded by the ruptured epidermis, black within. Perithecia com- 

 pressed and of various shapes. Ostiola short, stellate-sulcate. Asci 

 clavate, 8-spored. Sporidia cylindrical, curved, rounded at the ends, 

 yellowish-hyaline, 12-14 x 2 fi. 



On branches of Ceanothus, California (Harkness). 



D. eapnostoma, B. & Rav. in Rav. Fungi Car. IV, No. 42. 



Stromata scattered, small (1 mm.), erumpent, not circumscribed. 

 Perithecia few (3-6), globose, black, not deeply buried, rather less 

 than I mm. diam. T necks short, with prominent, short-cylindrical, per 

 fo rated ostiola, piercing the slightly pustulate epidermis together. 

 Asci stipitate, p. sp. 25-30 x 4 fi. Sporidia subbiseriate, 8 in an ascus, 

 allantoid, slightly curved, yellowish-hyaline, 5-7 x \\ [jl. 



On dead limbs of Morus, South Carolina (Ravenel). 



The stromatic material in which the perithecia lie is very scanty, 

 and of a dark color. Differs from D. infuscans, E. & E., in its cylin- 

 drical ostiola. 



D. Callicarpge, B. & Rav. in Rav. Fungi Car. IV, No. 41. 



Stromata thickly scattered, small, (1-1 J mm.), conic-hemispherical, 

 erumpent, white inside, not circumscribed. Perithecia 3-8, about J
