 Artliur. 



Sph^rella Thalictki, E. & E.— Perithecea hypophyllous, 90 /Jt in 

 diameter, of coarse, cellular structure, with a rather large opening above, 

 hem spheric, (flattened when dry,) scattered on small (2 — 3 mm.), round, 

 white sp )ts with a dark border. Asci sessile, about 36 x 7 /^-. Sporidia 

 crowded, ovate-oblong, granular and nucleate, (becoming uniseptate ?) 

 12—16 X 3— 4i . 



On leaves of T/ialictrum dioicum, Parsippany, IST. J., Prof. Wm. Tre- 

 lease. Sent also from Iowa by Mr. E. VV. Holway. 



Septoria Diervill^, E. & E. Spots dark brown (2—3 mm.), 

 mostly with a thick, swollen, raised border which is more pronounced on 

 the upper side of the leaf and more or less shaded purplish black. Peri- 

 thecia hypophyllous, small, black, innate-erumpent. Spores thread-like, 

 often strongly curved, nucleolate, 25—35 x 1— H /^-, with a slight greenish 

 tinge. 



On living leaves of Diervilla trifldct. Magnolia, Mass.. summer of 1884. 

 Miss C. H. Clarke. 



Melanconium gracile, E. & E.— Pustules rather prominent, 

 bursting out in a seriate manner through longitudinal cracks in the bark. 

 Stroma minuie, whitish. Spores oblong-cylindrical, pale brown, 15—18 

 X 4—5 /^-, oozing out in a dull black mass. 



On dead limbs of hickory, Plainfield, N. J., Geo. F. Meschutt. 



Gymnosporium gramineum, E. & E.— Forming small, black, elon- 

 gated or round patches 1 — 3 mm. in diameter, with the general aspect of 

 Torula herharum, Lk. Spores globose or subovate, 3—4 /^-. 



On dead culms and leaves of Arundinarice, "Low Country,'' South 

 Carolina, June, 1884, H. \V. Ravenel. 



Quite distinct from G. inquinaus, Berk, which also occurs on Arun- 

 dinaria. 



MoNiLiA DIFFUSA, E. & E.— Forms a thin, ferruginous stratum on 

 the matrix. Hyphse inconspicuous, branching into chains of 6 — 10 

 acutely elliptical, simple, subfuscous, spores 7 — 10 x 3—4 and separated 

 from each other by a short, hyaline connecting cell. 



On rotten wood, White Mountains, jS^. H., Sept. 1884; Miss S. Minns. 



Graphium LiNDER^, E. & E.— Amphigenous but mostly hypo- 

 phyllous, on large (i— 1 cm.) indefinitely limited spots of a light yellow 

 color at first but becoming dark brown and sometimes confluent. Hyphse 

 erect, simple, nearly straight, septate, brown, 25—30 x 4—5 /^-, forming 

 little pencil-like fascicles thickly scattered over the affecte i part of the 

 leaf and bearing at their tips the clavate-cylindrical, brown, multisep- 

 tate conidia, 75—85 x 6—7 /> , 



This much resembles G. clavisporum, B. & C.
