long to subspherical, contain I or 2, rarely 3 or 4, spores, and 

 are 16-32/z in length. The sterile cells usually incompletely 

 cover the spores, are hyaline or yellowish tinted, and sub- 

 spherical to oblong. The spores are reddish brown, oblong 

 to subspherical, often irregularly flattened, smooth, and 11-18^ 

 in length.

The smut possesses some economic importance, since it 

 occurs on cultivated rye. However, it apparently rarely be- 

 comes so abundant in the rye fields of this state as to cause 

 serious injury. So far the writer has been able to find only 

 a single smutted plant, though a number of fields have been 

 examined. 



Urocystis Hypoxyis Thaxt. The sori occur in the inner 

 and basal parts of the flowers, distorting and destroying them 

 more or less, and often run down somewhat on the pedicles ; 

 the infected parts have an irregular oblong shape, and finally 

 disclose the dusty, purple-black spore mass. The spore balls, 

 vary from ovoid to spherical, contain 1-8, chiefly 3-5, spores, 

 and are 25-60/x in length. The sterile cells completely cover 

 the spores, are reddish yellow, ovoid, and 9-14/u in length. 

 The spores are reddish brown, polyhedral, subspherical, or oc- 

 casionally ovoid to oblong, and usually 13-16/x in length.

This smut was originally described from the specimens 

 found by Professor Thaxter of Harvard in West Rock Park, 

 Westville. Since then it has been reported from Massa- 

 chusetts and South America.

The sori occur chiefly in the leaves, being permanently em- 

 bedded in their tissues, and forming discolored but usually 

 scarcely distorted areas. The spores are hyaline or yellowish 

 tinted, rarely darker colored, simple, separate, or occasionally 

 slightly adhering together in rows or irregular masses, and of 

 medium size. Elongated conidia are often produced from the
