Yermicularia discoidea, n. s. On dead culms of Panicum prolif- 
crum. Poiute a la Hache, La., February, 1887. Langlois, 1041. Peri- 
tliecia for some time covered by the epidermis, discoid, J-l millimeter 
in diameter, orbicular or subelliptical, rather thickly aud evenly cov¬ 
ered with straight continuous black bristles 79-80 by 4-5//, and sub- 
bulbouo at base. Sporules falcate with attenuated acute ends, 3-4 
nucleate, hyaline, 35-40 by 5//. This seems to be quite distinct from 
any described species. 
Haplosporella tingens, n. s. On dead culms of Andropogon 
muricatus. St. Martinsville, La., March, 1889. Langlois, 1783. Peri- 
thecia subcespitose, 2-3 together or densely crowded, often seriatelj 
erumpent, becoming nearly superficial, conical, about one-third milli¬ 
meter in diameter and one-half millimeter high. Sporules oblong-ellip¬ 
tical, 18-20 by 9-11//. The culm is tinged slaty-black within. 
Diplodia bambus^:, n. s. On dead stems of Bambusa. Mostly 
near the nodes. Perithecia hemispheric one-third to one-half millime¬ 
ter in diameter, papillate. Sporules elliptical, brown, 1-septate and 
slightly constricted, 15-20 by 8-10//. 
Diplodia cucurbitacej3, n. s. On dead pumpkin-vines. Pointe a 
la Hache, La., March, 1887. Langlois, No. 1049. Perithecia iunate- 
erumpent scattered, their apices projecting aud covered with the black¬ 
ened epidermis. Sporules elliptical, brown, 1 septate, 20-25 by 10-12//. 
Botryodiplodia varians, n. s. On dead limbs of Lagerstrcemia. 
St. Martinsville, La., January, 1889. Langlois, 1784. Perithecia erum¬ 
pent superficial, solitary, oftener connate in clusters of 2-4 or more, con¬ 
ical, rough except the obtusely conic ostioium, about one-half millime¬ 
ter in diameter and a little more than that in height. Sporules elliptical, 
brown mostly continuous, some of them 1-septate, not constricted, 
15-22 by 8-11//. This may be the Diplodia lagerstrcemice , Speg., but 
that is said to have u sublenticular ” perithecia only 200-250// in diam¬ 
eter. 
Hendersonia tini, 7i. s. On dead spots in living leaves of Viburnum 
tinus. Lafayette, La., December, 1887. Spots large (2-3 centimeters), 
cinereous with a purplish-red border. Perithecia amphigenous, pimc- 
tiform, innate-erumpent. Sporules fusoid, nucleolate, nearly straight, 
pale straw-yellow, 22-27 by 2J/z. Approaches Septoria. Probably the 
stylosporous stage of Leptosphaeria tini , E. & E. 
Prosthemiella hysterioides, n. s. On decorticated wood of 
Salix nigra. Near New Orleans, La., September, 1886. Langlois, 1792. 
Acervuli scattered, minute, punctiform or hysteriiform, covered above 
by a spurious perithecium, tinging the wood of a reddish color. 
Conidia in threes, cylindrical, hyaline, nucleate and imperfectly 5-0- 
septate, 30-35 by 1J//, arising from short cylindrical basidia.
