ical or slightly angled, have a thickish wall, and are 10-16^ in 

 length. The conidia may occur on either surface of the sorus 

 as a whitish growth, and are linear, somewhat curved, and 

 30-55/i by 1-2/i in size. 



Host and Distr. : Physalis pitbescens, South Manchester 

 (Thaxter) ; New Haven, Sept. 16, 1902, Sept. 30, 1903 ; 

 Physalis Virginiana, Hamden, Oct. 14, 1903. 



The cultivated strawberry tomato, Physalis pitbescens, is 

 sometimes rather seriously injured by this smut. The figure 

 shows the sori on this host, the spots having a definite darker 

 border. 



Entyloma Linariae Schrot. Fig. 30. The sori show as 

 small, faint, yellowish spots on the under surface of the leaves, 

 and are oval to circular in outline, and l />-2 mm. in diameter. 

 The hyaline or yellowish spores are chiefly subspherical or 

 spherical, smooth, have evident double wall, and are ii-i$h, 

 in length. The conidia have not been observed. 



Host and Distr. : Linaria vulgaris, Westville, Oct. 22, 

 1903. 



This species has been reported on this host only twice in 

 North America. The variety is more common. 



Entyloma Linariae var. Veronicas Wint. The sori are 

 somewhat more evident than in the typical form of the species, 

 showing on both sides of the leaf. The spores also are deeper 

 tinted and larger, 13-16/z, or rarely 19^, in length. 



Host and Distr. : Veronica peregrina, New Haven, May 

 16, 1904. 



Entyloma polysporum (Pk.) Farl. The sori form sub- 

 circular or more irregular, yellowish or (later) dark brown 

 spots, 2-5 mm., in the leaves; the surrounding tissue is often 

 killed, thereby merging the sori. The spores are usually hya- 

 line to yellowish, or more rarely even chestnut brown, ovoid 

 to spherical or somewhat polyhedral, smooth, provided with 

 evident thick double wall, and chiefly 12-17/u in length. Coni- 

 dia, apparently, are lacking. 



Host and Distr. : Ambrosia artemisiccfolia, Cheshire, Aug. 



3. I903- 



The closely related species Entyloma Compositarum Farl., 



also on Compositas as hosts, probably also occurs in this state, 



though not yet reported.
