Nectria ipomeae, Halst., Rep. N. Jersey. Agric. Expt. 

 St., 1891, p. 281, figs. Perithecia in little clusters, conico- 

 globose, acutely papillate, verrucosely squamulose, red ; 

 asci cylindric-clavate, 8-spored; spores hyaline, cylindric- 

 oblong, i-septate, slightly constricted at the septum. 



A Fusarium condition is present with this species. 



Nectria pandani, Tul., Fung. CarpoL, iii. p. 7 1 (as a foot- 

 note). Perithecia crowded, globose-ovate, papillate, pallid ; 

 asci cylindrical , 80 X 6 /x ; spores monostichous, shortly 

 lanceolate, straight, 10X4 /*, i-septate. 



Often accompanied by a conidial form scarcely differing 

 from Acrostalagmus dnnabarinus, except in its pale colour. 

 The Nectria springs from pustules of Melanconium pan- 

 dani, Lev., of which it is suspected as being the ascigerous 

 condition.

 p. n, f. 17, 22, 25. Perithecia solitary or 3-5, rarely 

 more, in a cluster, seated on a reddish-brown, well-
