270 PUCCINIA 
Uredospores. Sori amphigenous, on indefinite yellowish 
spots, scattered or in groups, elliptical or linear, soon naked, 
minute, rusty-yellow; spores ellipsoid to ovate, delicately echinu- 
late, yellowish, 20—30 x 15—20p (with 2—4 very distinct 
equatorial germ-pores on one face, McAlpine), 
Teleutospores. Sori very inconspicuous, amphigenous, scat- 
tered, minute, soon naked, elliptical or linear, blackish-brown ; 
spores elliptical or subpyriform or oblong, usually rounded 
above and thickened (up to 8), gently constricted, rounded 
or rarely attenuated below, smooth, chestnut-brown, 28—48 x 
16—22 4; pedicels persistent, brownish, up to 45 long. 
On leaves (living or fading) of Anthoxanthum odoratum. 
Very rare; King’s Lynn, 1884. 
The description is from Sydow, where it is stated that the uredo is 
frequent in mid-Germany, but the teleutospores are exceedingly rare. 
Plowright mentions that, mixed with the uredospores, he found a large 
number of hyaline capitate paraphyses; but Fischer states that the 
specimen in Sydows’ Uredineen (no. 458) has no paraphyses and none are 
mentioned in the description. In a doubtful specimen on Anthoxanthum 
from Switzerland, however, Fischer found paraphyses. McAlpine also 
found no paraphyses, but occasional mesospores, and states that the teleu- 
tospores are much more uncommon than the uredospores. He found his 
specimens on sheath and inflorescence of A. odoratum, as well as on the 
leaves. The only British specimens I have seen are those collected at 
King’s Lynn by Plowright in 1884, but it is also recorded for Yorkshire. 
The suggestion that this is a hetercecious species has so far received no 
confirmation.
