Charles B. Bessey— 
2 cm. long: asci cylindrical, attenuated at base, 150—160 x Iommm. 
ascospores 8, oblong-elliptical, curved, biguttulate, 26—32 x 10—11: 
mmm.: pataphyses filiform slightly clavate at apex, somewhat 
branched. Sclerotium black, thin, coriaceous, forked, 4% x 1% cm. 
In shady woods, near Lincoln, Nebr., (associated with Arythronium 
albidum?) The cups are from 2% to 34% mm. broad, a single stipe 
arising from each of the two to three forks of the sclerotium.

Puccinia buchloes Schofield, n. sp. III. Amphigenous, or mostly hy- 
pophyllus: sori scattered, or more ot less linear-clustered, epidermis 
of host plant splitting and supporting the edges of the sori: spores 
broadly elliptical, or slightly obovate, 13 to 23 broad by 29 to36m 
mm. long, mostly about 22 by 31 mmm., epispore smooth, light- 
brown, constricted at the septum, slightly thickened at the apex, 
which is obtusely rounded: pedicel stout, once or twice the length 
of the spore, tinted. On Buchloe dactyloides Engelm. Collected by 
J. G. Smith, Lincoln, Nebr., Oct. 1886.

Sorosporium cuneatum Schofield, n. sp. Glomerules nearly globose, 
38 to 48 mmm. in diameter, mostly about 44.5 mmm., bright 
brown, composed of from forty to fifty spores: spores 9 5 to 
11 mmm. long, crowded, and in optical section cuneate in outline, 
all minutely roughened on the basal (exposed) surface. 
In flower heads and stems of Grindelia sguarrosa Dunal. Lincoln, 
Nebr., in the autumn of 1891. 
The fungus attacks not only the heads, completely destroying the 
achenes, but it attacks the stem also, producing gall-like enlarge- 
ments. The spores in the stem are formed immediately under the 
bark. ; 
In California, according to Dr. Harkness, Sorosporium californicum 
Hark. attacks Grindelia robusta Nutt., reducing the flower-heads to 
one-third their natural size. In Nebraska the same reduction oc- 
curs on the lower branches of Grindelia squarrosa Dunal., but on 
the upper branches the parasite has the opposite effect, enlarging 
the heads to more than double their natural size.
