Family 76. DEMATIACEAE 



Hyphae dark or black, cobwebby, loose, usually rigid, not cohering in definite 

 fascicles ; conidia typically dark and concolorous, but sometimes the hyphae are 

 dark and conidia clear, or the conidia dark and the hyphae clear. This family is 

 parallel with the Moniliaceae and certain intermediate forms must be sought in 

 both places. 



Amerosporae

oblong. 



Micronemeae 



Hyphae very short or scarcely different from the conidia. 



I. Conidia not in chains 



1. Conidia globose to elliptic 



a. Sterile hyphae nearly obsolete Coniosporium 4: 238
