Pound and Clements : north American hyphomycetes. 735 



11. SPEGAZZINIA Sacc. Mich. 2:37. 1880, 

 Sporodochia convex, rather dense, black; conidiophores sub- 

 terete, fasciculate; conidia terminal, borne on sterigmata, sar- 

 ciniform, usually cruciate four- celled. 



One species is described for North America. 



12. DHRANIDION Harkn. Bull. Cal. Acad. Sci. 1:163 



1885. 



Sporodochia minute, pulvinate; conidiophores short, branch- 

 ing; conidia acrogenous, subterete, septate, bifurcate, of the 

 shape of a tuning fork. 



One species is described. 



13. EVERHARTIA Sacc. & Ell. Mich. 2:580. 1889. 

 Sporodochia verruciform, fuscous; conidiophores septate, 



subdichotomous or obsolete; conidia densely conglobate, or en- 

 closed in a viscous mass, at first involved in mucus, cylindrical, 

 many septate, once to several times spirally coiled, hyaline. 



Two species are described. In one species the conidiophores 

 are interwoven with sterile hyphae. 



14. TROPOSPORIUM Harkn. Bull. Cal. Acad. Sci. 1:34. 



1884. 



Sporodochia applanate, farinaceous; conidiophores elongate, 

 loose, branching; conidia hyaline, continuous, densely spirally 

 convolute. 



One species is described. , 



The Knyarieae might be divided into three groups, those like 

 Knyaria and Eymenella, with well developed conidiophores and 

 small, continuous or septate conidia; second, those genera with 

 the conidiophores greatly reduced or wanting, comprising 7, 8, 

 9 and 10, and, finally, those with staurosporous or helicospor- 

 ous conidia. But as these groups grade into one another the 

 division has seemed unnecessary. 



Tribe Cylindxocolleae. 



Sporodochium globose, or verruciform, sessile, or substipi- 

 tate; sporophore thin, elongated, generally much branched, 

 hyaline, or fuscous; conidia simple, cylindrical, concolorous, 

 catentate, the chains often branched. ,
