176 PUCCINIA 
[4cidiospores. Acidia hypophyllous, on brownish or pur- 
plish spots, more or less circinate, often on the petioles and 
then in elongated patches, cup-shaped, minute, with broad 
recurved torn white margin; spores delicately verruculose, 
pallid-yellow, 17—28 y.] 
Uredospores. Sori scattered or circinate, minute, often 
confluent, soon naked, brown; spores more or less ellipsoid, 
rarely ovate, faintly echinulate, pale-brown, 22—30 x 18—26 p, 
with two or three germ-pores just above the middle. 
Teleutospores. Sori similar, but long 
covered by the grey epidermis, black- 
brown; spores ellipsoid to oblong, ob- 
tuse or rounded above, more or less 
thickened (up to 9 y), gently constricted, 
rounded below, smooth, chestnut-brown, 
38—66 x 18—30 4; with them are 
intermixed (according to Sydow) ovoid 
mesospores, much thickened at the

Teleutospores on Convol- 681. brownish, thick, persistent, up to 
vulus sepium, Poughkeep- 
sie, U.S.A. 35 Be long. 
On Convolvulus sepium (Miss Jelly). June—October. Very 
rare. (Fig. 126.) 
The connection of the ecidiospores with the teleutospores was experi- 
mentally demonstrated by Arthur. According to Fischer, the uredospores 
often have a smooth median equatorial zone, of which I could see no trace. 
I have not seen the ecidia.
