2 cm. long: asci cylindrical, attenuated at base, 150 — 160 x ioramm. 

 ascospores 8, oblong-elliptical, curved, biguttulate, 26 — 32x10 — 11: 

 mmm.: pataphyses filiform slightly clavate at apex, somewhat 

 branched. Sclerotium black, thin, coriaceous, forked, ^ x i l / 2 cm. 

 In shady woods, near Lincoln, Nebr., (associated with Erythroniwn 

 albidum?) The cups are from 2% to 3^ mm. broad, a single stipe 

 arising from each of the two to three forks of the sclerotium.

78. Puccinia buchloes Schofield, n. sp. III. Amphigenous, or mostly by- 



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 to 36 m 

 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.

79. 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 squarrosa 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 calif omicum 

 Hark, attacks Grindelia robusta Nutt., reducing the flower-heads to 

 one-chird 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.
