Type habitat: On rotten log, Nov. 15, 1893 (Niittall, 

 discov. 1286, 231). 



Sporodochia globose, 100 to no /* diameter, cespitose, 

 forming tufts about i mm. diameter. Hyphse 6 to 8 /x, thick, 

 branched, the branches curved or tortuous. Conidia globose 

 or ovate 6 to 12 /^ diameter. 



Differs from / coccinclbini Cke. in its color, and larger 

 cespitose sporodochia. 

 I. MALiFOLioRUM, J. L. Sheldon, Torreya, 8:139-41 (1908). 



Spots suborbicular, or coalescing and becoming irregular, 

 brown or sometimes mottled with gray and with a small gray 

 spot near the center, 5 to 15 mm. in diameter; sporodochia 

 hypophyllous, minute, gelatinous, yellowish-amber and black- 

 ening, subspherical when moist (i^Ofx), becoming disc-shaped 

 or irregular when dry (60 to lOO/x,) ; sporophores branched; 

 conidia hyaline, oblong, i x 3.5 to 4^. 



On leaves of Mains in various parts of the State (SJieldon), 

 Greenbrier, near \\'hite Sulphur Springs (IVaitc). 



HYMENULA Fr. 

 H. CEREALis E. & E., Proc. Phila. Acad., 1894, 386. 



Type habitat : On wheat straw Triticum sp. brought in 

 from Painesville, Ohio, May 24, 1894 {Nuttall, discov. 1520, 



495)- 



Sporodochia gelatinous, orbicular, yellowish-amber color 



becoming darker, at first sub-pulvinate, becoming depressed 

 or flattened, .5 to .75 mm. diameter. Basidia slender, 25 

 to 30 X 1.25 ju, simple or oftener branched. The branches 

 erect. Conidia hyaline, oblong, minute. 3 to 4 x i to 1.25 fx. 



CYLINDROCOLLA, Bon. 

 C. Dendroctoni Peck, in ]\Iillsp. Flora, W. \'a., 1892, 516. 



Type habitat : On dead insects, Dcndroctonns frontalis,

 (Millspaugh). 



The insects are probably killed by this fvmgus, as they lie 

 dead in their burrows in the inner bark of the tree (Piiins 

 Virginiana). 



Sporodochia minute, forming irregular masses, soft, some- 

 what waxy, white or whitish ; sporophores slender, abun- 

 dantly branched above, often compacted below into a short 

 stem-like base, spores catenulate, short cylindrical, subtrun- 

 cate, colorless, .00016 to .0002 in. long, .00008 to .0001 in. 

 broad.
