57. Septoria lagenophor^, n.sp. 



Spots more or less orbicular, on both surfaces of leaf, dirty fawn 

 to dirty brown, distinct, and from 3-8 mm. in diam. Perithecia 

 minute, innate, subgregarious, black, olivaceous by transmitted 

 light, depressed globose, delicately membranaceous, with distinct 

 round papillate mouth, 80-100 fi diam. Sporules hyaline, filiform, 

 straight, curved or flexuous, apparently 1-2 septate, very slender, 

 19-24: fx long, average 21 /x.

 hillai'dieri, Cass.; Nov., 1902 (Robinson). 



It differs from S. sonchi, Sacc, in the distinct spots, and the 

 slightly smaller perithecia, as well as in the sporules being much 

 more slender. The apparent clear septa may be guttules which 

 occupy the entire breadth of the narrow sporules. Puccinia 

 lagenophorce, Cooke, both in its aecidial and teleuto-form may 

 occur on both surfaces of the spot, which, however, is primarily 

 caused by the Seploi^ia. 



58. Septoria varia, n.sp. 



Spots dry, brown or grey, rather indefinite, sometimes defined 

 by a black line. Perithecia minute, black, immersed, membra- 

 naceous, globose to lenticular, with protruding papillate mouth, 

 80-130 yii. Sporules hyaline, filiform, straight or curved, at first 

 continuous, then at maturity distinctly 3-septate, issuing in 

 tendrils when moist, 35-45 x 1-1 J m-

 1900; Jackson Creek, Oct., 1900 (C. French, Jr.); Kiewa Valley, 

 Nov., 1902 (Robinson). 



There are various species of this genus found on Plantago, but 

 they differ from the above. S. heterochroa, Desm., has spores 

 25 yi long. >S'. inconspicua, B.C., has spores 55 x 2J/li. S. planta- 

 ginisj Sacc, has filiform-clavate spores, and those of S. 2)^a')ita- 

 ginea, Pass., are pluri-septate and 55 x 2^ fx. In aS'. vanhoeffeniiy 

 Henn., the spores are only 15-21 x 2-2 J /x.
