Lophiostoma hysterioides, Ell. & Langlois.—On rotten oak 
stumps, St. Martinsville, La., July, 1888. Langlois., 1406. Peri- 
tliecia gregarious, subglobose with their bases slightly sunk in the 
wood, mostly a little less than J mm. diam., ostiolum forming a 
narrow ridge entirely across the perithecia and thus giving them the 
appearance of Hysterium. Ascicylindrical, 60—70 x 5—6 with 
abundant paraphyses. Sporidia biseriate, fusoid, nearly straight, 
3-septate, smoky-hyaline, 14—16 x 3, the next to the upper cell 
swollen. 
Lophiostoma (Lophtospirera) meridionale.— On rotten wood, 
St. Martinsville, La., May, 1888. Langlois No. 1205 Perithecia 
scattered, minute (J mm.) compressed buried in the wood, the 
projecting flattened black ostiolum alone being visible. Asci cla- 
vate—-cylindrical, 75 x 8—9 with abundant paraphyses. Sporidia 
biseriate, fusoid hyaline, slightly curved, 1—septate, and slightly 
constricted, 30—35 x 5. 
Leptosphhsria filamentosa, E. & E.—On dead places in liv¬ 
ing leaves of Yucca filamentosa, Newfield, N. J., July, 1888. 
Perithecia immersed scattered, small (200—225 micr.), depressed- 
globose the upper part slightly raising and barely rupturing the 
cuticle ostiolum not prominent. Asci subcylindrical, 75—80 x 7 
—8, with abundant paraphyses. Sporidia biseriate, oblong-cylin¬ 
drical, 3—septate, yellow, constricted* at the septa, not curved, 
12—15 x 4—5, ends obtuse. The spermogonial stage is a Conio- 
thyrium (C. concentricu?n) ? with small (4 micr.), subglobose, brown 
sporules. The parts of the leaf (mostly the sides or tips) occupied 
by the ascigerou s’'stage of this species are quite dead and already 
partly decayed and brittle. 
Metasphaeria punctulata, E.'& E.—On dead culms of Pan- 
icum Curtisii, St. Martinsville, La., March, 1888. Langlois 1358 
Perithecia scattered, immersed, the surface of the culm remaining, 
quite even but blackened around the small erumpent black ostiola 
or finally more or less uniformly blackened. Perithecia globose 
|| mm. diam. with a white, rather firm nucleus. Asci clavate- 
cylindrical 80—110 x 20 with indistinct paraphyses. Sporidia 
fusoid, slightly curved, 3—septate, hyaline, 40—50 x 6—7. 
Pleospora pustulans, E. & E.—On the exposed inner surface 
of bark of Fraxinns. Clyde, N. Y., April, 1888. O. F. Cook, No. 
538. Perithecia gregarious, membranaceous ovate-globose, §—f 
mm. diam. raising the bark into subconical pustules with the 
papilliform ostiolum erumpent. Asci clavate-cylindrical, with a 
short stipitate base, about 100 x 15 micr., with abundant paraphyses, 
Sporidia uniseriate or subbiseriate varying from ovate to oblong
