Phyllosticta kalmicola (Schw). 



Depazea kalmicola Schw., Syn. N. Am., No. 1812, (pr. p). On 

 living leaves of Kalmia latifolia. Newfield, N. J. April, 1893. 



Spots amphigenous, orbicular, 1-2 mm. diam., white, with a dark 

 purple margin shading off into reddish-purple. The white is less 

 conspicuous below. Perithecia epiphyllous, depressed globose, sub- 

 cuticular, black, 100-200// diam., sometimes concentrically arranged 

 on the spots, semi-erumpent, but closely covered by the transparent 

 cuticle which is often stellately cleft, but not reflexed, rather broadly 

 pierced above. Sporules oblong elliptical, hyaline, minute (2-3 x l/i). 



The Depazea kalmicola Schw., embraces both a Septoria and a 

 Phyllosticta, not outwardly distinguishable ; the former issued in de 

 Thiimen's Mycotheca, No. 1494, Ell. N. A. F. 344, Roum. F. G. 

 2327 and Rab. F. E. 2792. Ell. and Everhart, N. A. F., 2d Ser. 

 2661 is a different thing, the spots having a raised border and the 

 sporules being longer. The label to this last No. is erroneous. It 

 should read on Kalmia angustifolia, and the Syn., "tSphaeria kalmi- 

 aecola " should be canceled. 



Phyllosticta latifolia E. & E. 



On leaves of Kalmia latifolia, Newfield, N. J. May, 1893. 



Spots amphigenous, orbicular, 3-5 mm. diam., rusty brown with a 

 shaded, dark red border, indistinctly zonate. Perithecia buried, 

 150-200//. diam., the apex rupturing the epidermis but hardly erum- 

 pent, circinately arranged so as to leave an empty space in the center 

 of the spot. Sporules acutely and narrowly elliptical, hyaline, 

 6-8 x 2£— 3£// on basidia about as long as the sporules. 



Differs from Ph. kalmicola (Schw.) in its brown, subzonate 

 spots, circinate perithecia and larger sporules. 



Phyllosticta discincola E. & E. 



On leaves of Forsythia Cult. , Washington, D. C. , Com. D. G. 

 Fairchild. 



Spots amphigeneous, grayish- brown, 1-3 mm. diam., suborbicular, 

 bounded on both sides by a distinct raised line giving the appearance
