SPH^ERIA ORTHOGRAMMA B. & C. 



Old stems of Indian corn. North Grreenbush. Oct. 

 Sterile. 



Sph^eria Partstassije n. sp. 



Perithecia scattered, convex or sub-hemispherical, prom 

 inent, pierced, black ; asci cylindrical ; spores long, narrow, 

 uniseptate, generally constricted at the septum, often slightly 

 curved, colored, .OOIS'-.OOIG' long, with one or two nuclei 

 in each cell. 



Dead stems of Parnassia Caroliniana. Albany. Sept. 



Speleria Arceuthobii n. sp. 



Perithecia small, densely csaspitose, oblong or cylindrical, 

 very obtuse, shining, black ; asci subclavate, fugacious ; 

 spores crowded, globose, colorless, .00016' in diameter. 



Capsules of Arceuthobium pusillum. Forestburgh. 

 Sept. (Plate 1, figs. 10-14.) 



It forms little black tufts, crowning the fruit at the tips 

 of the stems and branches. I have not seen it on the stam- 

 inate plant. I am not fully satisfied that the generic refer- 

 erence is correct, as the perithecia seem to be mouthless. It 

 is interesting to observe the extent to which parasitism pre- 

 vails. The Arceuthobium is a parasite on the spruce, this 

 fungus is parasitic on the Arceuthobium, and in a few 

 instances a third parasite, a minute white mold, was seen 

 on the perithecia of the fungus
