WITH PLATE XXIX. 
Chrysomyxa Arctostaphyli, n. sp.—Sori hypophyllous on 
red brown spots of about 4™" diameter, arranged into groups, 
flattened, of irregular outline. Depth of the layers 160- | 
240u, spore cells' oblong, about 18 in diameter. 
On Arctostaphylos Uva Ursi. Wisconsin, leg. Dawis (no. 
921), comm. Ellis. 
Chrysomyxa Chiogenis, n. sp.—Spots yellowish or none; 
sori hypophyllous, scattered. Uredo layers appearing, when 
fresh, honey colored; uredospores formed in chains, ovate, 
22-29 X 15-21 #, with colorless, coarsely verrucose mem- 
branes. Teleutosori orange-red, waxy, 95-120 in depth, 
Spores 8-124 in diameter. : 
On Chiogenes serpyllifolia. Wisconsin, June, 1893, leg. 
Davis (no. 6,078), comm. Ellis. 
: By the dimensions of the spores this species is hardly dis- 
tinguishable from C hrysomyxa Pyrole (DC.), but the uredo- 
0 
reba of notice although small, consists in the structure of 
; membranes of the uredospores. In Chr. Chiogenis the 
of be more dense staff-like portions of the membrane are 
like “ig than in Chr. Pyrolez. On the other hand the staff- 
s ru . . 
Ledi (Alb. et Schw.) and Chr. Rhododendri (DC.) than in our 
Species under consideration.
