206 PUCCINIA 
’ 
oblong to clavate, rounded above and not thickened, evidently 
constricted, usually attenuated below, 
smooth, brown, 55—90 x 20—35 w (or 
even 100 u long); pedicels hyaline, per- 
sistent, very long, (reaching 160 4). 
On Buaxus sempervirens. Rather 
common. September, October, lasting 
through the winter and following spring. 
(Fig. 153.) 
The spores of this species easily fall apart 
into their component cells. Ed. Fischer proved 
that it has only the one spore-form : he gives 
(.c.) figures showing the effect upon the leaf 
of an infection by the basidiospores. Accord- 
ing to him, the teleutospores germinate in 
spring, and infect the delicate young leaves. 
The mycelium grows slowly. During the 
summer and autumn the infected spot becomes 
much thickened : the sori are produced in late 
; autumn or during the following winter. This 
z= Nee = Sia is exactly in accordance with the suggestion 
: made by Plowright (/.c.), without any experi- 
mental evidence being at that time available. 
DISTRIBUTION: Europe and Persia.

Teleutospores. Sori hypophyllous or amphigenous, and on 
the petioles and stems, on conspicuous yellow or orange spots, 
scattered but close together, small, hemispherical or on the 
stems elongated, pulvinate, compact, hard, at first pale-reddish, 
then reddish-brown; spores oblong to subfusoid, attenuated 
at both ends or rarely rounded above, thickened at the apex, 
gently constricted, smooth, yellowish-brown, 35—75 x 12—26 p; 
pedicels hyaline, persistent, short or as much as 150 long; 
one-, three-, or even four-celled spores also occur.
