WHITE MILDEWS OR BLIGHTS. 179 



lected together into an irregular linear body, wMcli 

 consists principally of the conglomerated sporidia. 



One other very common and troublesome little 

 fungus (Eurotium herhariorum) will for the pre- 

 sent close our examples. This is found creeping 

 over dried plants preserved in herbaria, on 

 decaying fruit, preserves, and various other sub- 

 stances, sometimes animal as well as vegetable, 

 but chiefly the latter. To the naked eye it ap- 

 pears as a myriad of little yellow spherical bodies, 

 of the size of very small pins' heads, resting 

 upon fine cobweb-like threads (fig. 260). When 

 magnified, the surface of the conceptacles is seen to 

 be reticulated (fig. 261). In the interior the spo- 

 ridia are borne, contained also, as in the former 

 instance, in asci. It has been demonstrated almost 

 beyond any doubt, that this mildew is a compound 

 fruited (ascigerous) condition of an equally common 

 mould [Asjpergillus), 



Dr. Shortt, of Chingleput, in a recent report 

 •on the growth and production of Indian Cotton, 

 remarks that the plants are subject to the 

 attacks of a kind of mildew. He writes : — 

 '^ They appear in the form of rounded fibres 

 or thallus, shooting up in the air, having the 

 lamina of the leaf as a base, and feeling villous to 

 the touch. The small fibrillae that form the nap 

 appear shooting up as sharp projections when seen 

 by the naked eye; under the microscope they are 

 found to consist of pointed tubes, interspersed here
