Astern i A radians n. sp .—On living leaves of Capparis cynophal- 
lophora. Florida, 1891. (No. 256, Simpson’s collection.) Peritliecia 
hemispherical, black, rough, with a black, shiny, compressed or sub- 
pyramidal ostiolum, finally collapsing slightly above; about in di¬ 
ameter; hemispherical; densely crowded and radiately arranged in 
orbicular patches 3-4 mm in diameter on the upper side of the leaf. Asci 
' elliptical, briefiy stipitate, 35 by 20//, distinctly paraphysate, paraphyses 
slightly thickened at the apex. Sporidia 8 in an ascus, ovate, 12-15 
by 5-5^//, uniseptate, slightly constricted at the septum, yellowish 
hyaline, becoming brown. 
Acantiiostigma eraxtni n. sp. —On leaves of living Fraxinus 
americana. Near Washington, D. 0., August, 1889. (M. B. Waite.) 
Peritliecia epiphyllous, scattered, superficial, black, sub-hemispherical, 
about 150// in diameter, of parenchymatous texture (astomous?), covered 
with short, black, scattering, spreading bristles 30-40 by 4//. A sci sub- 
ovate, about 35 by 15//, short-stipitate 4 (-8) ? spored. Sporidia (as far as 
seen) 4 in an ascus, clavate, 3-4-septate, 25-30 by 4-5//, deeply constricted 
at the septa, yellowish or greenish hyaline. The upper cell of the 
sporidium is elliptical and broader and shorter than those below. The 
leaf is mottled with reddish brown spots and the peritliecia are scat¬ 
tered alike over these spots and over the green parts of the leaf. 
Coniotiiyrium MusoicoLUM n. sp .—On capsules of Polytrichum. 
Carlin,Ya., August, 1892. Perithecialenticular, membranaceous,black, 
astomous, 75-90// in diameter, covered by the thin epidermis, through 
which it is distinctly visible. Sporules globose, yellow brown, 8-10//. 
This resembles outwardly Stayonospora rauii Ell. on the same host, 
but the sporules are very different. 
Stagonospora baccharidis n. sp .—On living leaves of Baccharis. 
Virginia Beach, Ya., under pine trees, May 28, 1891. (W. T. Swingle.) 
Epiphyllous. Perithecia superficial or nearly so, hemispherical, 110- 
120// in diameter, broadly perforated above, black, of tolerably coarse 
cellular texture. Conidia broad-fusoid, yellowish hyaline, 2-septate, 
nearly straight, 25-30 by 6-7//, arising directly from the cells of the pro- 
ligenous layer, with no perceptible basidia. 
Septoria ampelopsidis n. sp .—On leaves of Ampdopsis quinque- 
folia. Oregon, Ill., September 14, 18S9. (M. B. Waite.) Spots numer¬ 
ous, angular or otherwise irregular, limited by the veirdets of the leaf, 
subconfiuent, greenish at first, becoming dark brown, occupying the 
greater part of the leaf, which becomes mottled with yellow. Perithe¬ 
cia buried in the parenchyma of the leaf, but prominent on both sur¬ 
faces, subglobose, 80-100// i n diameter, perforated. Sporules vermiform 
or clavate-cylindrical, hyaline, 30-50 by 3-3J//, 4-8-septate. This ap¬ 
proaches Cylindrosporium on account of the imperfectly developed 
perithecia. 
Septoria miorospora n. sp.— On leaves of Asprclla hysirix. Craw- 
fordsville, Ind., August, 1890. (E. M. Fisher, No. 101.) Perithecia
