lei filaments, or cell ularly fleshy ; spores simple, crowded, 

 on simple sporophores arising at summit and on the 

 stalk. 



4. Tuhercularia. Receptacle fleshy, of continuous sterile 

 and threadlike beaded fertile filaments. Finally indurated, 

 floccose, with spores scattered over it, or falling into 

 powder. 



5. Periola. Receptacle cellular, sessile, fertile filaments 

 abbreviated, torulose, mixed with septate lax sterile fila- 

 ments. 



6. Volutella. Receptacle cellular, compact, with long 

 rigid bristles ; spores spindle-shaped, septate, on continu- 

 ous short filaments, all over the receptacle. 



7. Fusarium. Receptacle cellular, gelatinous ; spores 

 spindle-shaped, simple, somewhat curved, on simple fila- 

 ments forming a discoid stratum. 



8. Illosporium. Receptacle sub-gelatinous, diffluent ; 

 spores simple, pellucid, generally with hyaline envelope 

 on short filaments. 



9. Epicoccum. Receptacle cellular, on effused patch ; 

 spores four-sided, cellular, singly to short filaments. 



Family III. DEMATIEI. Mycelium filamentous, spores 

 compound or simple, rising from apices of erect, solid, cor- 

 ticate, subopaque filaments, or produced from solution of 

 the plants. 



Gen. 1. Cephalotrichum. Fertile filaments stalklike, 

 erect, septate, terminating in a globose capitule formed 

 by radiating forked or ternate branches bearing globular 

 spores at the tips. 



2. Sporocybe. Filaments fibrous, subulate, capitate, 

 with simple spores conglobated into a terminal head. 



3. (Edemium. Filaments rigid, erect, almost continu- 

 ous, or annulated, bearing at the sides globular masses of 

 spores. 



4. Myxotrichum. Filaments erect, scarcely septate ;
