MILDEWS, RUSTS AND SMUTS 
Teleutospores. Sori scattered, minute, circular or oblong, 
elongated on the leafstalk, powdery, dusky brown ; spores 
elliptical or oblong, ends rounded, tip not thickened, 
scarcely constricted at the septum, netted, brown or yel¬ 
lowish-brown, 24—-36 X 16—25 p, pedicel slender. 
Syn. Puccinia pimpinellae, Strauss, in Plowr., Ured., 
P- 155 (in part). 
On Anthriscus silvestris, Chaerophyllum temulum and 
Myrrhis odorata. Britain and Europe generally. 
CONIUM 
Puccinia conii, Fuckel. 
Uredospores. Sori minute, circular, scattered or rarely 
in clusters, powdery, pale cinnamon, on the under surface 
of the leaves, or on the leafstalks ; spores subglobose or 
elliptical, tip echinulate and thickened, with three' germ- 
pores, pale brownish-yellow, 24—36 x 17—26 p. 
Teleuto spores. Sori similar to those of the uredospores, 
dusky brown, sometimes for a long time covered by the 
epidermis when on the petioles ; spores ovate or oblong- 
ovate, tip rounded, scarcely thickened, scarcely constricted 
at the septum, almost smooth, pale brown, 30—50 x 20— 
30 p', pedicel short, deciduous. 
‘ Distinguished from Puccinia hullata, Winter, by the 
uredospores being smooth, except at the thickened tip.

HERACLEUM 
yijj Puccinia heraclei, Grev. 
Aecidia. In dense irregular or elongated clusters on the 
under surface of the leaves, more especially following the 
veins, very often also on the leafstalks, on slightly thickened 
yellowish or brownish spots, forming cup-shaped pustules, 
the wall scanty ; spores angularly globose, mimitely warted, 
yellowish, 21—32 x 18—28 p. 
Uredospores. Sori scattered, minute, chestnut-brown, 
on both surfaces of the leaf ; spores subglobose or elliptical, 
densely echinulate, pale brown, 25—32 X 19—27 p, with 
three or four germ-tubes. 
; Teleuto spores. Sori minute, scattered, or more or less 
crowded and following the veins, powdery, blackish-brown ; 
spores elliptical, ends rounded, very slightly constricted at
