Aecidium zephyranthis sp. nov. 
Spermagonia sordid yellowish, occupying circular yellowish 
spots I-2 mm. in diameter ; spermatia globose or subglobose, 2-3 # 
diameter. . 
Pseudoperidia amphigenous, crowded in 1-4 irregular circular 
series about the spermagonial spots, short with white torn edges, 
200-300 # diameter, cells irregularly quadrangular or pentagonal, 
21~35 4 diameter, closely reticulated, appearing densely and ml-

On leaves of Zephyranthes sp. near Tlalpam, Valley of Mexico, 
Mexico, Dr. J. N. Rose, no. 5478, July 15 ,1901. Witha $- or 
1- in, objective the cells of the pseudoperidia appear papillate but 
with a ;1,- oil immersion the surface is seen to be densely reticulate- 
ridged. 
Diatrypella rimosa sp. nov. 
Stromata scattered or somewhat gregarious, erumpent, mostly 
elliptical, sometimes suborbicular, white within, 1-3 mm. long 
mostly 2 mm., slightly constricted at the base, closely surrounded 
by the ruptured epidermis and a black circumscribing line whi 
reaches to the wood leaving a whitish scar when the bark 18 ff 
moved ; disk plane or slightly convex, nearly smooth except for 
the slightly prominent indistinctly 4-sulcate ostiola, transve y 
rimose ; perithecia 5-15, monostichous, ovate or angular by mutu 
pressure; asci elongate-clavate, long-stipitate, paraphysate, af 
135 x 6-7 4 (p. sp. 60-70 x 6-7); paraphyses numerous, slender, 
multiguttulate, longer than the asci; sporidia numerous, yellowish-

Type material on A/nus sp., Wallowa Lake, Oregon, no. 980 
C. L. S., 1899, distributed in Griffiths, West American Fungi 2° 
320. Apparently most nearly related to D. discoidea alnt Cooke. = 
differs in having the surface of the disk almost pure black, the oe om 
less conspicuous and not so distinctly stellate, and also in its rimose 
character. 
From D. tocciacana it differs in the form and color of the 
stroma, the stroma being contracted at the base instead of enlarg 
From D. verrucaeformis it differs in its more regular, get 
darker and rimose stroma and less conspicuous and less regu! 
ostiola as well as in the measurements of the asci.
