360 THE MICROSCOPIST. 



2. Papularia. Sporidia quite simple, collected in groups 

 under epiderm of dead plants, set free in a pulverulent 

 patch by the decay of the epidermis. 



3. Stilbospora. Sporidia septate (septa evanescent), full 

 of sporidiola, adhering in a 'nucleus, at length breaking 

 out. 



4. Didymosporium.-^-As the last, but the sporidia didy- 

 rnous (septate in middle). Color black or fuscous. 



5. Cytispora. Sporidia simple, stick-shaped, minute, in 

 a multilocular nucleus, at length opening by a common 

 apical pore and emerging as a gelatinous tendril. 



6. Mdasmia. Sporidia minute, stick-shaped, in a flat, 

 thin nucleus, which bursts at apex and extrudes the spores 

 in a gelatinous globule. 



7. Micropera. Sporidia linear, curved, formed in nu- 

 clei, bursting by distinct pores, and discharged mixed with 

 jelly. 



8. Ceuthospora. Sporidia simple, ovate, contained in 

 several globose nuclei in a common stroma, escaping by a 

 simple lancinate pore. 



9. Nemaspora. Sporidia simple, spindle-shaped, in nu- 

 clei in a common grumous stroma and opening by a com- 

 mon pore. 



10. Discella. Sporidia elongated, simple or uniseptate, 

 stalked, in a nucleus with perithecium. 



11. Cylindrosporium (Glceosporium). Sporidia simple, 

 elliptical, stalked, in nucleus covered only by cuticle of 

 leaf, finally extruded in a gelatinous tendril. 



12. Coryneum. Sporidia spindle-shaped, multiseptate, 

 stalked, crowded, breaking out on surface as a pulvinate 

 disk. 



13. JBactridium. Sporidia spindle-shaped, multiseptate, 

 transparent at ends, tufted on a superficial creeping my- 

 celium. 



14. Eriospora. Sporidia filiform, originally attached in
