NEW NORTH AMERICAN FUNGI. 
103 
scattered, surrounded by the ruptured epidermis, mostly small, 
sometimes flattened above. Sporules clavate-oblong or subfusoid 
oblong, yellowish, 3—7-septate and sometimes constricted at the 
septa, 15—25 x 4—5, ends subobtuse. 
Stagonospora Myric^e, E. & E.—On fallen leaves of Myrica 
cerifera , Newfield, N. J., June ’88. Perithecia hypophyllous, 
scattered, erumpent-superficial, depressed, black, shiny, pierced 
above, 70—80 micr, diam. Sporules cylindrical, hyaline, straight, 
ends rounded, 18—22 x 2 J—3, on very short basidia. Sphcerella 
Myricce E , & E. and Gnomonia Myricai C. & E. occur on the 
same leaves. 
Septoria gallarum E. & E.—On old Solidago galls, Pratt’s 
Falls, N. Y., May ’88. Underwood & Cook, No. 568. Perithecia 
scattered, minute, erumpent, black. Sporules linear-cylindrical, 
slightly curved, yellowish-hyaline,'nucleate, 35—45 x 1 J, abundant. 
Dinemasporium radiatum, E. & E.—On dead twigs of Celtis 
occidentals, West Chester, Pa., Dec. 87. Perithecia erumpent, 
gregarious, \—J mm. diam., cupuliform, the margin fringed with 
stiff, black, continuous hairs 50—70 x 2|—3, incurved when dry. 
Basidia simple, cylindrical, brownish 25—50 x 1J each bearing at 
its apex an ovate-oblong, hyaline, 2—3 nucleate sporule 6—7 x 
2—2J, with a single erect, straight bristle like hair rising from its 
apex and 4—5 horizontally spreading hairs 9—12 micr., long 
radiating from its base at the point of juncture with its basidium. 
The sporules sometimes become faintly uniseptate. The species 
differs from the usual type of Dinemasporium in its uniseptate 
sporules and radiating hairs which resemble the crest of a Pesta- 
lozzia but proceed from the base instead of the apex of the sporule. 
Leptothyriitm castanicolum, E. & E.—On living leaves of 
Castanea vesca, Newfield, N. J., OcC ’88. Scattered over the 
upper surface of the leaf, both on the green parts and on the 
white spots formed bv Gloesporium epiphyllum but its occurrence 
on the spots is only accidental. Perithecia scutellate, of radiate- 
fibrous structure, orbicular, slaty-black, 115—150 micr. diam. 
with the margin even or subcrenate. This must be quite different 
from L. Castanece, Spreng. (Sacc. Syll. Ill, p. 628) which has 
cylyndrical sporules 5—6 x 0, 7. 
Glceosporium podophyllinum, E. & E.—On living leaves of 
Podophyllum peltatum, Concordia, Mo., May ’88, Rev. C. H. 
Demetrio, No. 157. Maculicolous. On light brown (1 cm.) spots 
with a darker greenish border. Acervuli amphigenous, white, 
erumpent. Spores variable in size and shape ovate 12—15 x 5—7
