In view of the morphology of the sooty blotch fungus, 

 as described on the previous pages, it is obvious that it 

 does not belong to any of the genera just discussed, and, 

 moreover, that it possesses characters sufficiently strik- 

 ing and distinctive to warrant the erection of a new genus 

 to receive it. For this I propose the name Gloeodes, 

 gelatinous, referring to the gelatinous interior of the 

 pycnidium, '\\T.th the following generic description: 

 Gloeodes nov. gen. 



Mycelium strictly superficial, dark colored, septate, 

 profusely branched, often anastomosing, constituting a 

 thallus, often fern-like in appearance but occasionally of 

 other types; pycnidia dimidiate, membrano-carbonous, 

 interior gelatinous ; paraphyses present ; conidia oblong, 

 one-celled, hyaline.
