PHYTOLOGY AND THERAPEUTICS. 167 
Perithecia scattered, compressed, about 14 mm. long, partly covered by the 
loosened fibers of the wood. Sporules oblong-elliptical, 10-14x5-6 micros. Not 
constricted. Differs from D. microsporella Sacc., especially in its compressed 
perithecia. 
231. Hendersonia lophiostomoides E, & B., n. sp. 
On decorticated, weather-beaten limbs of Maclura aurantiaca, Rooks county, 
Kansas, March 31, 1897. (No. 2352.) 
Perithecia scattered, erumpent-superficial, 400-500 micros in diam., subglo- 
bose, partly covered by the loosened fibers of the wood. Ostiolum mostly com- 
pressed, as in Lophiostoma. Sporules oblong-elliptical, brown, 3-septate but 
scarcely constricted, rounded and obtuse at the ends, 12-20x6-8 micros. At first 
hyaline and uniseptate. 
232. Stagonospora cytisporoides HE. & B.,n. sp. 
On dead branches of Amorpha fruticosa, Rooks county, Kansas, February 
20, 1897. (No. 2372.) 
Perithecia scattered, subcuticular, about 144 mm_ in diameter, raising the epi- 
dermis into pustules pierced by the small white disc with a single perforation. 
Sporules oblong-cylindrical, hyaline, 3-4-nucleate, often becoming 2-3-septate, 
12-15 x3-315 micros. 
233. Camarosporium juglandis E. & B., n. sp. 
On dead limbs of Juglans nigra, Rooks county, Kansas, January 9, 1899. 
(No. 2531.) : 
Perithecia thickly scattered and sometimes partly connected by a slight stro- 
matic crust, small, mostly less than 15 mm. in diameter, globose, covered by the 
epidermis, which is raised into pustules perforated at the apex. Sporules variable 
in size and shape, from subglobose, 8-12 micros in diameter, to ovate or elliptical, 
12-25 micros in diameter, 3-septate. The larger ones constricted at the septa and 
submuriform. 
234. Cladotrichum brassice E. & B., n. sp. 
On old cabbage leaves (Brassica oleracea), Rooks county, Kansas, April 
22, 1897. (No. 2399.) 
Forming dense, subolivaceous, subpulvinate tufts, 1 mm. to 15 cm. across, 
and thickly scattered over both sides of the leaf. Fertile hyphe erect, sparingly 
branched and sparingly septate, swollen at intervals, yellowish-brown, 110-150 x6 
-~7 micros. Conidia oblong-elliptical, brown, 12—20x 10-12 micros, 1-(exception- 
ally 3-) septate. 
HYPHOMYCETES (MILDEWS).
