coriaceo-membranaceous texture. Asci cylindrical, 300-400 x 4-5 p 

 with thread-like paraphyses longer than the asci. Sporidia 8 in an 

 ascus, filiform, continuous, lying parallel. 



On dead leaves of Ulmus, Celtis and Vitis, South Carolina, and 

 on leaves of Smilax, Texas (Ravenel), on leaves of Vitis, New Jersey. 



The specimens on leaves of Vitis and Celtis are darker and 

 smaller than those on Smilax and Ulmus, but do not appear to differ 

 otherwise. 



A. Ravenelii, B. & C. Grev. 1. c. 



Perithecia short, nearly cylindrical at first, then clavate, 300-450 

 fi high, and 70-80 fi thick (while retaining the cylindrical form), be- 

 coming as much as 150 p. thick when clavate, color quite dark. Asci 

 180-210 x 3-4 jut, with filiform paraphyses a little longer than the asci. 

 Sporidia filiform, nearly as long as the asci, separating into joints 

 12-15 fj. long. 



This is a smaller species than A. foliicolum, Berk, from which it 

 is safely distinguished by its jointed sporidia. 



In Rav. F. Am. 735, on leaves of Fraxinus, the specimens in 

 the copies we have seen are too poor to enable one to decide with cer- 

 tainty, but as far as can be ascertained, the sporidia are continuous and 

 if so this No. is referable to A. foliicolum, Berk. 



SELINIA, Karst. 



Symb. ad Mycol. Fenn. Ill, (1876). 



Stromata carnose, at first small, elliptical or tubercular, becoming 

 confluent, irregular, red, covered with a rusty-red conidial layer. 

 Perithecia one or at least only a few in each stroma, buried, globose, 

 pale, carnose, with a thick, conical, prominent ostiolum. Asci elon- 

 gated- ventricose, containing 4-8 continuous, elliptical, hyaline, spo- 

 ridia. Paraphyses filiform, septate. 



S. pulchra, (Winter). 



Hypocreopsis pulchra, Winter in Hedwigia 1875, p. 26. 

 Winteria pulchra, Sacc. Mich. I, p. 281. 

 Selinia pulchra, Sacc. Syll. 4586. 



Stromata at first small, subcorneal in the center, mostly becoming 

 confluent and forming a rusty-red crust, the surface of which is over- 

 spread with a rusty-brown, conidial layer bearing short, cylindrical 

 conidia. Perithecia buried, globose, about J mm. diam., witli thick, 

 conical ostiola. Asci ventricose below, narrower above, sessile, 270 x
