minor E. & E.) These three forms of stylospores are appar¬ 
ently generically connected with the ascigerous form. This last 
mentioned may be only a more mature stage of growth of Sep- 
toria megaspora Speg. which is described as having uniseptate 
spores and perithecia not on spots. The fungus on Hesperaloe 
has typically 3-septate spores and fhe spotted leaves are very 
conspicuous. Dr. Trelease has sent on Agave sp. from Mexico, 
a fungus that in some respects comes nearer Spegazzini’s plant 
but in this, too, the spores are 6-8-septate. Septoria megaspora 
Speg. seems more properly a Phleospora. 
Dothidea yucc^e E. & E.— (Phyllachora yuccse E. & E. 
Torr. Bull. 22:440. 1895.) On leaves of Yucca angustifolia, 
Manitou, Colorado. July, 1895. (Prof. E. T. Harper, 474). 
Stromata gregarious amphigenous, small, sunk in the sub¬ 
stance of the leaf and covered by epidermis which is soon rup¬ 
tured, mostly oblong, mm., surrounding and blackening 
the leaf for § cm. in extent, the adjacent parts of the leaf being 
entirely free from the fungus. Ascigerous cells numerous, small. 
Asci oblong-cylindrical, 75-80x10-12 a. Sporidia mostly bise- 
riate, ovate-oblong, yellow-brown, uniseptate and constricted, 
12-15 x 5~6 /*. 
This is evidently the mature state of the fungus cited above, 
the larger dimensions of the asci being due to their more perfect 
development. 
Hysterographium nucicola (Schw.) Syn. N. A. F. 2080. 
(H. hians E. & E. in Herb.)—On old hickory-nuts lying on the 
ground. Newfield, N. J., April 7, 1902. 
Gregarious elongated f-i mm. long by nearly mm. wide, 
lying in various directions on the matrix, shining black, smooth,, 
not distinctly striate, straight or curved, ends obtuse, lips dis¬ 
tinctly gaping. Asci oblong-clavate, paraphysate, 60-70x12-15 
u Sporidia ovate-oblong biseriate, hyaline, becoming dark 
brown, 4-6-septate, with a longitudinal septum running through 
1-3 of the cells, sometimes distinctly constricted in the middle 
but often scarcely constricted at any of the septa, 15-22x6-9 
In the shape of the perithecia and the partly open lips this 
differs from the description and specimens of H. nucicola Schw. 
in Herb. Schw. at the Acad. Nat. Sci. Philadelphia. The sur¬ 
face of the nut is more or less blackened around each group of 
perithecia but this is more like a discoloration than a crust.
