septate, brown. Conidia oblong, uniseptate, hyaline, 20 —50 !J- long. 

 On leaves of Liriodendron Tidipifera, Yineland, J. October. 



53. Cercospora leptosperma, Pk. SOtli Rep. N. Y. St. Mus , p. 55. 

 Ilyphse tufted, short, hyaline, seated on pale greenish, angular. 



indefinite spots. Conidia colorless, very slender, subfiliform, 75 long, 

 slightly thicker toward the base where there are usually I or 2 obscure 

 septa. 



On living leaves of Aralia nudicauUs, Iowa (Holway.) 



54. Cercospora tuberosa, E. & K. Bull. Torr. Bot. Club, XI, p. IIG. 

 Hypophyllous, on spots (.75— .5 cm.) at first gray and imperfecily 



defined, but at lengtli dirty brown and of irregular outline, angular, 

 elongated and partly limited by the veinlets of the leaf, hyphse arising 

 from a small tubercular base, nearly straight and more or less toothed 

 above, septate, brown, 35 — i5 x 4 Conidia subcylindric, slightly taper- 

 ing upwards, subfuscous, 5— lO-septate, 80—110 x 3.5 — 4 



The spots are darker and more distinctly defined on the upper side of 

 the leaf. This differs from Xo. 15 chiefly in the character of the spots. 



On leaves of Apios tuberosa, Kansas (Kellerman.) 



Cercospora glaucescens. Winter, which is the same as this, was pub- 

 lished in Rab.-Winter Fungi, about the same time that G. tuberosa 

 appeared in the Bulletin, so that it is difficult to say which has prece- 

 dence. Dr. Winter's specimens were from Missouri. 



55. Cercospora elongata, Pk. 33d Rep. N". Y. State Mus., p. 29. 

 Spots irregular, angular, limited by the veinlets of the leaf, often 



confluent, sometimes arid, brown, grayish brown or cinereous. Hyphse 

 amphigenous, tufted, colored, subflexuous. sometimes nodulose. Conidia 

 elongated, obscurely 3— many-septate, attenuated, colorless, 50-150 x 4-5 

 On living leaves of Bipsacus sylvestris, Aug., N. Y. (Peck.) 



56. Cercospora alth^etna, Sacc. Mich. 1, p. 269. 



Spots thickly scattered over the leaf (2—4 mm.), subangular, partly 

 limited by the veinlets of the leaf , olivaceous, becoming grayish-brown, 

 with a narrow, darker, slightly raised border. Hyphse csespitose, amphi- 

 genous, fuscous, nearly snaight, scarcely septate, 40—60 x 5 Conidia 

 fusoid-cylindrical, 3—5 septate, only moderately attenuated above, hya" 

 line. The above notes are from specimens found by Dr. Farlow on 

 Althcea rosea, at Wood's Holl. Mass., and they agree so well w^ith Saccar- 

 do's description of C. althceina that we think it is that species, though we 

 have no authentic specimen for comparison. 



C. malvicola, E. & M., Am. Nat., Oct. '82, p. 810, N. A.F. 821, is 

 probably only a form of this, differing principally in its longer (80 — 112/^ ) 

 hyphse and conidia (75—90 /^.) 



Specimens on Callirrhoe (V) collected by Dr. Kellerman at Great Bend, 

 Ks., Aug. 1884, are essentially the same as A. F. 821, and specimens 

 on Abutilon Avicennce from Manhattan, Ks., Sept. '84, though differing 

 somewhat in general aspect, do not show any marked difference in their
