ON GENTIANA 179 
aculeolate, brownish-yellow, 20—80 x 18—24 py, with two, 
rarely three, germ-pores. 
Teleutospores. Sori similar and also on the stems, but 
pulverulent and black-brown ; 
spores ellipsoid to ovoid, 
rounded at both ends, not 
thickened above, but some- 
times with a low broad papilla, 
not constricted, smooth, dark- 
chestnut, 28—38 x 24—30 w; Fig. 128. P. Gentianae. Teleutospore, 
pedicels hyaline, thin, rather  feawih ee pag 
long, very deciduous; occa- 
sionally there are a few mesospores intermixed. 
On Gentiuna acaulis. Uredo- and teleutospores, Kew 
Gardens, August, 1905 (M. C. Cooke), and Horsham (W. G. 
Smith). (Fig. 128.) 
I have a specimen on G. Andrewsii, from the United States, with 
exactly similar teleutospores. The ecidia are said to appear in April and 
June, and more frequently on the stems and peduncles than on the leaves. 
Jaczewski’s AZicidium was on calyx, stem and leaf of G. angustifolia, on 
pale orange spots. 
DisTRIBUTION: Europe, Siberia, East Indies, North 
America.
