174 British Uvredinee and Ustilagineae. 
Puccinia paludosa. Plow. 
icidiospores—Pseudoperidia irregularly clustered on the leaves, 
petioles, peduncles, stems, and sometimes even on the calices, 
sub-immersed, with torn white edges. Spores subglobose, 
echinulate, hyaline, with orange contents, 15-28 X r1o-16p. 
Uredospores—Sori small, oval or elongated, on yellowish spots, 
light brown, soon naked, and pulverulent. Spores round, 
rarely oval, brown, rough with small, sharply pointed, not 
very numerous warts, 20-25y. 
Teleutospores—Sori small, oval or elongate, rarely roundish, often 
in linear series, black, naked. Spores, upper cell rounded and 
thickened above, often obliquely, lower cell subcylindrical or 
cuneiform, constriction rather marked, smooth, dark brown, 
50-60 x 18-204. Pedicels rather long, brownish, persistent.

fEcidiospores on Pedicularis palustris, June and July. 
Uredospores on Carex vulgaris, stricta, fulva, and panicea (2), 
July and August ; teleutospores, August to June. 
BioLocy.—In June, 1888, I found the zcidiospores at Irstead, 
Norfolk, in company with the last year’s teleutospores. The latter 
germinated freely, and, when applied to Pedicularis palustris, give rise 
to the ascidiospores. Conversely, the zcidiospores, applied to Carex 
vulgaris, give rise to the uredospores and teleutospores. Professor 
Trail has found this species in Orkney. 
Pucecinia obscura. Schrot. 
4 cidiospores—Pseudoperidia on large roundish or elongate dis- 
coloured spots, mostly epiphyllous, shortly cylindrical, with 
torn white edges. Spores irregularly globose, finely echinu- 
late, 18-20 in diameter.
