SMUT. A prevalent disease c.f njauy ctiltivated cereal 

 grasses and other plants caused by the attack of a 

 fungtis of the class ustilagineae. sometimes prodiicing 

 swellings on various parts of the host, the swellings 

 being eventually filled with brownish or blackish sp<.>res 

 known as chlaniydospores. which emerge, as a tine dust- 

 like powder, when the outer membrane of the hyper- 

 trophic tissues bursts or cracks. The smut on Indian 

 corn may be taken as typical. The disease usually ap- 

 pears first on the leaves. afterwar<ls at the .iunction of 

 leaf-sheath andbla.de: finally tlie earof corn is attacked, 

 and the tassel. On the leaves blisters are found: on 

 the ear, large. whiti<li polished swellings appear. As 

 the spores mature, tije swellings become darker in 

 color, and the inclosing membrane finally rupttires. ex- 

 posing the dark olive-green mass of spores. Unlike 

 most other cereals, maize can be inoculated at any age. 

 Several smuts have been described; viz.. loose smut 

 of oats [UstUago arena'}, maize and teosinte smut 

 ( Ustitagozefi^), stinking smut of wheat ( TiUetia tritici). 

 rye smut { Croct/xtis occulta), onion smut ( rrocijxtis 

 cepulip), and colcbicum smut i Croctistis coJchici). For

 cious, fading a few days after opening. Lvs. with 

 sheathing bases, plicate-venose; fls. membranaceous,
