Material has been gathered and prepared for distribution in 
Fungi Columbiani preparatory to which it would seem desirable 
to give the species a name. It may be characterized as follows: 
Synchytrium scirpi Davis n. sp., subg. Pycnochytrium.— 
Spots minute, reddish brown. Distortion of the host slight, 
the “galls” seldom projecting more than 50 /*, from the surface 
of the leaf. Resting spores amphigenous, scattered or aggre¬ 
gated, produced singly in the epidermal cells, globose, ovoid, 
elliptical, esuboidal or brick shaped, 60-110 x 50-75 /x in diameter. 
' Epispore dark brown; endospore lighter brown, 3-5 thick. 
Spore contents coarsely granular, staining black with osmid acid. 
On leaves of Scirpus atrovirens Miihk, Kenosha county, 
Wisconsin, August and September.

O. Spermogonia few, in the center of the clusters of aecidia, 
epiphyllous, about 80 fx in diameter. 
I. Aecidia epiphyllous, on yellow spots 1-2 mm. in diameter, 
surrounding the spermagonia mostly 8-10 on the spot, minute, 
160-240 ix in diameter, low, peridia split into irregular segments; 
aecidiospores very irregular in shape and size, globose, ovate, 
angular, elliptical, or with one or both ends acute, and with the 
exception of the globose ones, with both ends thickened up to 8 /x, 
tuberculate, pale brown, 28-40 x 18-26 /x ; germ-pores numerous, 
minute. 
III. Teleutosori black, amphigenous, pulverulent, puncti- 
form, sometimes occurring only on the margin of the underside 
of the leaves, causing a discoloration about 5 mm. in width all 
the way around; teleutospores globose, tuberculate, septa all ver¬ 
tical, apex mostly with a broad cap about 4 fx thick, 28-36 x 
24-38 jx ; pedicel hyaline, fragile, up to 75 /x long. 
On Salvia Sessei Benth. Cuernavaca, Mex. Sept. 26, 1898, 
No. 3012 (type for the aecidium) ; Sept. 30, 1899, No. 3539. 
On Salvia ballotaeflora Benth. New Mex. (type for III.). No 
uredospores could be found, although search was made for them 
each year. If the teleutospores are treated with caustic they swell 
so as to measure 36-44 x 36 and the caps become very distinct. 
The germ-pores of the teleutospores are not all at or near the
