and not as narrow as in S. Andropogi, and the specc. resemble Phyl- 

 lachora graminis more closely than S. Andropogi does. There are 

 also asci, but the sporidia are still immature. This is common around 

 Newfield, but so far, always sterile. It is no doubt a small form of 

 Phyllachora graminis, Pers. 



1485. Sphceria Andropogi, Schw. Small (1 x J mm.), elongated 

 strips of sterile crust with some Vermicularia or Golletotrichum f 



1487. Sphceria canaliculata, Schw. This (sec. Cooke, Grev. 

 XIII, p. 43) is Puccinia cellulosa, Berk. 



1490. Sphceria Panici, Schw. On withered leaves of species 

 of Panicum, and 



1491. Sphceria Agrostidis, Schw. On Agrostis Jiliformis, are 

 apparently referable to Phyllachora. Schweinitz himself remarks 

 that the latter may be only a Var. of P. graminis. 



1492.* Sphceria Iridis, Schw. Frequent (sec. Schw.) on leaves 

 of Iris, at Kaighn's Point, Philadelphia, Pa. Affords elliptical, hyaline 

 stylospores 10x5//, and is different from 1464, Sphceria iridicola, 

 Schw. 



1568. Sphceria Lecythea, Schw. Syn. Car. 155, Fr. S. M. II, 

 p. 460. This (sec. Cke. Grev. XVI, p. 98) is a Sphceropsis. 



1820. Sphceria cesculicola, Fr., is entirely sterile. 



1811. Sphceria Pyrolce, Fr. Black, sterile spots on leaves of 

 Chimaphila umbellata. Sphcerella Pyrolce, Rostr. (p. 282) may not 

 be distinct from this. 



1813. Sphceria frondicola, Fr., on a leaf of Sassafras, is en- 

 tirely sterile; small, subcuticular stromata (or perithecia)? on spots 

 \ cm. across. 



1815. Sphceria carpinicola, Fr. The spec, in Herb. Schw. is 

 a Gloeosporium.. Spores linear, 8-10 x 1J ju, curved. Acervuli flesh- 

 colored, minute, thickly scattered over the under side of the leaf, but 

 not on any spots. 



1817. Sphazria Dianthi, A. & S., var. Saponarice, Kze. The 

 spec, in Herb. Schw. is a Septoria, on round, white spots with a 

 reddish margin, epiphyllous, thickly scattered. Sporules cylindrical, 

 nearly straight, some of them becoming obscurely 3-septate. Septoria 

 Dianthi, Desm.?
