USHLA'GO. A genus of fungi, in which the proto- 

 spores are produced in masses, filling the tissues with 

 simple cells of a black colour. They are known as smuts, 

 and are very injurious to corn and grasses. The young 

 fruits or grains seen to be attacked should have the stems 

 cut and burnt before the spores are ripe. Oats and barley 

 often get badly attacked by U. segetum, and grain should 

 be treated with some disinfectant before sowing, if the 

 fungus was present when growing. One pound of sul- 

 phate of copper, dissolved in five quarts of water, is 

 sufficient for a sack of grain (four bushels), which should 

 be steeped in the solution. 



UTRICULAHIA. Bladderwort. (From utriculus, a 

 small skin, or water-bottle made of it ; in reference to 

 the small bladders on the floating or submerged leaves 

 of the plants. Nat. ord. Lentibulariaceas. Allied to 

 Pinguicula.) 



A very large genus of plants spread over the whole 

 world in boggy and wet places, or submerged in water. 

 They float near the surface in summer, and their flower 

 scapes are produced above the water. Divisions. Our 

 native species may be grown in ponds, tanks, or tubs. 

 Moist stove species, such as U. montana, may best be 

 grown in baskets of sphagnum, mixed with small pieces 

 of charcoal and drained with crocks. The small bladders 

 are best developed on the species which live in water, 

 and may be defective or absent from those that grow in 

 sphagnum or moss. In our native species they have a 

 small opening or trap-door which opens inwards, and the 

 interior is furnished with four-branched hairs. Minute 

 animals in the water, either seeking for shelter, or out 

 of curiosity, push against the trap-door, which opens to 

 let them in but closes behind them, thus making prisoners 

 of them. After a time they die, decay, and the nutrient 

 matter of their bodies is absorbed by the branching hairs.
