362 THE MICROSCOPIST. 



Family IV. TORULACEI. Mycelium filamentous, grow- 

 ing on the surface of decayed vegetables, bearing erect 

 filaments, terminating in rows of simple or compound 

 spores. 



Gen. 1. Torula. Spores in beaded chains, simple, readily 

 separating, placed on short continuous or septate pedicel. 



2. Bispora. Spores uniseptate. 



3. Septonema. Several transverse septa in the spores. 



4. Alternaria. Cellular spores connected by filiform 

 isthmus. 



5. Sporidesmium. Spores in tufts, straight, subclavate 

 or fusiform, shortly stalked or sessile, transversely sep- 

 tate or cellular. 



6. Sporochisma. Filaments erect, simple, external mem- 

 brane inarticulate. Spores articulate in fours. 



7. Tetraploa. Spores sessile, quadriseptate, in bundles 

 of four, each crowned with a bristle. 



8. Coniothedum. Spores without septa, in heaps, finally 

 separating into a powder. 



9. Echinobotryum. Spores rounded apiculate, in fasci- 

 cles, or erect annulated filaments. 



10. Sporendonema. Erect filaments with single rows 

 of spores in the interior. 



11. Spiloccea. Spores globose, adhering together and to 

 the matrix, forming spots laid bare by separation of epi- 

 dermis. 



12. Achorion. Mycelium ramose, articulated, joints 

 terminating in round, oval, or irregular spores (conidia?). 



13. Speira. Spores connate in concentric filaments, 

 forming horseshoe-like lamina, finally separating. 



14. Trimmatostroma. Spores curved, multiseptate, in 

 beaded rows, separating. 



15. Gyrocerus. Spores connate in spirally coiled fila- 

 ments, separating. 



16. Dictyosporium. Spores tongue-shaped, reticularly 

 cellular.
