sponum, but the larger acervuli and the firmly conglutinated mass of 
ejected spores are of the same character as in Gloeosporium. In all the 
genuine species of Cylindrosporium , the spores are ejected from the 
minute and usually numerous acervuli in loosely fioccose or pulverulent 
masses which are usually more or less confluent. Cylindrosporium Padi , 
Karst., belongs in this same category. 
Gloeosporium Diospyiii, E. <fc E.— On leaves of Diospyrus Virgini- 
anus. Faulkland, Del., August, 1887. A. Commons, Ko. GOG. Acervuli 
innate, erumpent on the upper side of the leaf on the veinlets of the 
leaf in small, pale-tuberculiform masses ; spores ovate, granular, 6—14 
x 5—7 p. The leaf is more or less yellow and the part occupied by the 
fungus dull olive-brown. 
Gloeosporium prunicolum, E. & E.—On living leaves of Prunus 
Virginiana. Racine, Wis., July, 1887. Dr. J. J. Davis. Maculicola; 
spots irregular, 3—10 millim. in diameter, dark rusty brown, finally 
deciduous ; acervuli innate, minute ; spores elliptical, mostly 4—6 x 24 
P, discharged in minute, whitish heaps on both sides of the leaf but 
more abundantly below. 
Gloeosporium necator, E. & E.—On living canes of black and 
red raspberry. Sent from Evanston, Ill., by Chas. Wheeler, August, 
1881, and from Cobden, Ill., by E. S. .Earle, June, 1884; also received 
from Columbia, Mo., June, 1887, from B. T. Galloway. Spots caulicolous, 
pale, with a slightly raised, dark border, 2—3 millim. in diameter, orbic¬ 
ular or elliptical; spores oblong-elliptical, 5—7 x 3 p, oozing out in an 
amber-colored mass through a single opening in the center of each spot. 
Reported as being very injurious. G. Venetum , Sacc., has spores of about 
the same size but is a foliicolous species. The Illinois specimens were 
reported as PhyllosticM necator , but the fungus is evidently a Gloeospo¬ 
rium. 
Gloeosporium Argemonis, E. & E.—On living leaves of Argemone 
platyceras. Manhattan, Kas., July, 1887. W. T. Swingle. Maculicola; 
spots amphigenous, definite, suborbicular, dirty gray above, purplish 
black below and subzonate, mostly about a half cm. in diameter, with a 
slightly raised, narrow margin; acervuli minute, scattered, mostly 
erumpent below, discharging the spores in small yellowish and amber- 
colored heaps; spores subcylindrical, arcuate, hyaline, granular and 
nucleolate, mostly a little narrower at one end, 22—40 x 24—3 /'-. 
Gloeosporium rostratum, E. & E.—On living leaves of Corylus 
rostrata. British Columbia, May, 1887. Prof. John Macoun. Maculicola; 
spots amphigenous, subrotund, 1—2 millim. in diameter, pale rust color, 
margin narrow and darker; acervuli minute, mostly clustered in the 
center of the spots, amber color, epiphyllous; spores cylindrical, curved, 
35—45 x 24—3 /'-, granular and nucleate, with indications of becoming at 
length three-septate. This is quite different from G. Coryli (Desrn.), 
which is mostly hypophvllous and has spores 12—15 x 5—6 p.
