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. 



I), bullulata, (Berk.) 



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



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

 from a filamentose base. Sporidia uniseriate, uniseptate, slightly 

 attenuated at each end, 15 x 6-8 1 //. 



On leaves, Disco Island. 



D. Artemisia, (Sclnv.) 



SphcEt-ia Artemisia;, 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 umbilicate, 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. 

 Grev. 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 sub- 

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



'* Sporidia conthruoux, hyaline (Bagnisiella), or colored (Auers- 



ivaldia). 



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



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

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

 times slio-htlv attenuated towards each end, simple, hyaline, 30 x 10 u."
