underground pipe, runs into a filter-tank, and then into a roofed 
reservoir. Tufts of a filamentous fungus were found floating in, 
tufts were from centimetr ] , and were s 
obscured by a brown deposit that the details of the filaments were 
difficult to make out. is deposit was found to be rust s 
soluble in dilute hydrochloric acid, and, upon the further addition 
of potassium ferrocyanide, yielded an abundant formation of prussian 
blue. The water in which the plant grew contained a small quantity 
of iron in solution. Now, it is known that some of the lowest fungi 
—Leptothriz, Crenothriz, and Cladothriz—have the power of con- 
verting ferrous bicarbonate to ferric hydrate, and they are even

Apodya should be capable of dealing with iron in a similar way 
seems to be a novel fact. The plant is saprophytic on organic 
matter in running water, for instance, in streams which receive the 
effluent waters from distilleries and paper-mills. Apodya lactea was 
originally described as an alga, and appears in English Floras under 
the name Leptomitus lacteus Ag. It should be added that there is 
still some doubt as to how the plant found its way into the Meole 
water-pipe; but the probable source was not the coal-mine, but a 
water-course near to the filter-tank, and flooded by a long rainy 
season.
