and vain search extending over many years; it has been confirmed by 
Tubeuf, Klebahn, and Bub4k. The ecidia of three other species, Melam- 
psorella Symphyti, Pucciniastrum pustulatum and Calyptospora Goeppertiana, 
which also live on the same host, do not cause any deformation of the 
shoots, and can therefore be easily distinguished. ,

[Spermogones. Chiefly hypophyllous, crowded, often spread 
over the whole leaf, orange-yellow. 
Aicidiospores. Aicidia hypophyllous, in two rows parallel 
to the mid-rib, not crowded, shortly 
cylindrical 4—#% mm. high, opening at 
the summit by a cleft, at length torn 
to the base into 8—5 segments; spores.

whole leaf, at first covered by the eae a 
epidermis and a thin peridium, then 
pulverulent ; spores ovate or ellipsoid, finely verruculose, yellow, 
28—35 x 21—28 p, without evident germ-pores. 
[Teleutospores. Hypophyllous, developed within the epi- 
dermal cells, forming large whitish or pinkish patches, many 
crowded in each cell, pale-yellowish, smooth, 11—18 x9—15 u.] 
[Aicidia on leaves of Abies pectinata, May, June;] uredo- 
[and teleutospores] on Symphytum officinale, rather uncommon, 
May to September. (Fig. 271.) 
Only the uredospores have so far been recorded for Britain, but the 
teleutospores would in all probability occur on the same plants at a later 
date, while the zcidia could doubtless be found, if carefully looked for, in
