On living foliage of Juniperus Virginiana, South Carolina 

 (Ravenel). 



A very distinct and well marked species. The general appear- 

 ance is that of Stigmatea Juniperi, (Desm.), but the microscopical 

 characters are very different, as above noted. The last three species 

 differ in their thicker stroma, which approaches Dothidea. 



D. bullnlata, (Berk.) 



Dothidea bullulata, Berk. Nares. Arct. Expd. II, 322. 



Disks small, bullate, marked by the punctiform ostiola, arising 

 from a filamentose base. Sporidia uniseriate, uniseptate, slightly 

 attenuated at each end, 15 x 6-8 p. 



On leaves, Disco Island. 



D. Arteraisise, (Schw.) 



Spluzria Artemisitz, Schw. Syn. N. Am. 1227. 



Small (4 mm,), ovate, subangular, subcupulate, margined by the 

 lobes of the stellately-ruptured epidermis, erumpent, subconfluent, very 

 black, with the disk rugose. Ostiola urnbilicate, not prominent, 

 numerous. Perithecia globose, minute, hollow, buried in the stroma 

 which is seated on the inner bark, nearly free, black and rugose on 

 both sides, not really confluent, but crowded. Sporidia (sec. Berk. 

 Grew IV, p. 104) oblong, uniseptate, constricted at the septum, 25 // 

 long. 



On branches of Artemisia, Bethlehem, Pa. (Schw.)-. 



DOTHIDEA, Fr. 



Obs. II, p. 347. 



Stroma erumpent, mostly pulvinate or tuberculiform, slightly 

 arched, flat or slightly concave above, black, wrinkled or punctate 

 from the ostiola. Perithecia (cells) sunk in the stroma. Sporidia suit- 

 elliptical or elongated, 2-celled, hyaline or colored. 



* Sporidia continuous, hyaline (Bagnisiella), or colored (Aners- 



waldia). 



D. Ilicis, ke. Texas Fungi, No. 143. 



" Gregarious, erumpent. Pustules elliptical, black, the cells be- 

 ing enclosed in the stroma. Asci clavate. Sporidia elliptical, some- 

 times slightly attenuated towards each end, simple, hyaline, 30 x 10 jt." 



On bark of Ilex opaca, Texas (Ravenel).
