long, .0003 to .0004 broad ; paraphyses slightly surpassing the 

 asci, several times forked or multifid at the apex. 



Dead branches of mesquit, Prosopis juUflora. Austin, Texas. 

 November. Underwood. 



This species is apparently related to E. Braziliense.^ from 

 which I have separated it because of its more slender asci and 

 smaller spores. 



Chsetophoma setigera n. sp. 



Perithecia minute, .003 to .005 in. broad, gregarious, epiphyl- 

 lous and amphigenous, subglobose, black, seated on a thin effused 

 superficial separable blackish stratum of interwoven filaments 

 and adorned with a few slender erect or divergent black seta> 

 .003 to .(►Otis in. long; spores numerous, minute, elliptical or 

 oblong, colorless, .00016 to .00024 in. long, .00008 to .0001 broad, 

 often with a minute nucleus at each end. 



Living leaves of coast live oak, Quercits agrifolia. Berkeley, 

 California. March. M. B. Howe. 



Cylindrocolla Dendroctoni Pk. 



(Flora of West Virginia, p. 516.) 



Sporodochia minute, forming irregular masses, white or whitish, 

 somewhat waxy ; sporophores slender, abundantly branched 

 above, often compacted below into a short stem-like base ; spores 

 catenulate, short C3dindrical, subtruncate, colorless, .00016 to 

 .D002 in. long, .00008 to .0001 broad. 



Dead insects, Dertdroctonus frontalis^ and the inner bark of 

 pine just about them. West Yirginia. May. C. F. Millsjpaugh. 



The insects are probably killed by the fungus as they lie dead 

 in the furrows which they had excavated in the inner bark of 

 pine trees, Pinus inops.
