234 PUCCINIA 
Teleutospores. Sori oblong or linear, often confluent, 
generally on the stems, rarely on the leaves (phylloclades), 
blackish-brown ; spores ellipsoid to clavate, thickened (up to 
8 w) and rounded above, very gently constricted, rounded below, 
smooth, brown, 35—52 x 17—26 yw; pedicels hyaline or brown- 
ish, persistent, as long as or longer than the spore; a few 
obovate mesospores intermixed. 
On Asparagus officinales. Aicidia, not common, May; 
uredo- and teleutospores, September—December, rather fre- 
quent. (Fig. 180.) ‘ 
Fischer points out that the connection between the ecidium and the 
other spore-forms has not yet been demonstrated. This disease is often 
very destructive to asparagus beds ; all diseased shoots should be gathered 
and burnt. The best means of prevention is by the selection of resistant 
varieties, and the avoidance of overcrowding.

Spermogones. Numerous, especially at the apex of the 
affected leaves, yellowish, conical. 
[dicidiospores. Aicidia few, scattered, alae deeply im- 
mersed, whitish, the narrow opening only pro- 
jecting; spores minutely verruculose, orange, 
about 15—20 p.] 
Leleutospores. Sori amphigenous, embedded 
in the dried yellowish parts of the leaf, hemi- 
spherical, densely crowded, often confluent, long 
covered by the ashy-grey epidermis which at 
length opens by a cleft, then naked, pulverulent, 
reddish-brown; spores oblong-fusiform or cla- 
vate, not thickened above and rounded or fre- 
quently somewhat narrowed, not constricted,
