2 5~3°/* broad, four- to five-septate, the upper cells vertically or 

 obliquely divided. 



Bark of sugar maple, Ottawa, Canada. September. Prof. 

 J. Macoun. 



Closely related to 5. piriformis but distinct by its larger spores. 

 It is perhaps this fungus which in Grevillea 2: 153, is re- 

 ferred to 5. ccllulosiun, but according to Sylloge Fung. 3 : 804, 

 the spores of that species are much smaller. 



Sphaeropsis fertilis. 



Perithecia numerous, closely and uniformly scattered, erump- 

 ant, surrounded by the elevated remains of the ruptured epidermis, 

 black; spores elliptical or oblong, 1 7-27/1 long, 12.5 p broad. 



Dead branches of green ash, Fraxinus viridis, Rockport, 

 Kansas. February. E. Bartholomew. 



This differs but little from 5. biformis, except in having the 

 perithecia more numerous and more uniform in size and position. 



Chromosporium atrorubrum. 



Effused, forming a thin dark red or rubiginous pulverulent 

 stratum ; spores globose, verrucose, 7.5 fi broad. 



Decaying wood of pine, Ottawa, Canada. September. Ma- 

 coun. 



Under a lens, the spores appear to be collected in minute clus- 

 ters. The hyphae are not conspicuous, the spores forming the 

 chief part of the stratum and giving color to it. The globose 

 spores separate it from C. latcritium and C. mbiginosum. 



Hypomyces purpureus. 



Subiculum effused, purple, permeating, transforming and dis- 

 coloring the matrix ; perithecia minute, sunk in the subiculum, the 

 ostiola emergent, black ; asci cylindrical ; spores fusiform, unisep- 

 ta te, purple, with a cusp-like point at each end, 35~4°^ lon S> 

 7-5 ,« broad, oozing out and forming beautiful purple masses or 

 Patches on the surface of the matrix.
