 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 fruity 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). "VVTien 

 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 considered probablG, 

 but as yet not fully proved, that this mildew is 

 a compound fruited (ascigerous) condition of an 

 equally common mould {Aspergillus), 



Dr. Shortt, of Chingleput, in a recent report 

 on the growth and production of Indian Cotton, 

 remarks that tlie 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 fibrillse 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
