Teleutospores. Sori hypophyllous, rarely epiphyllous, often 

 on the petioles and stems, scattered or circi- 

 oate, minute, sometimes (especially on the 

 stems) confluent and larger, long covered by 

 the epidermis, then surrounded by it, round- 

 ish or irregular, ferruginous-brown ; spores 

 ellipsoid or oblong, rounded and not thick- 

 ened above, but with a pale papilla to each 

 germ-pore, constricted, rounded or somewhat 

 attenuated below, smooth, pale-brown, 26 —

tundifolia. 



45 x 12 — 22 ft; pedicels hyaline, thin, deciduous, as long as the 



spore or shorter. 



On Campanula Rapunculus, C. rotundifolia. 

 June — August. (Fig. 111.) 



Not common. 



According to Sydow, the statement in Cooke's Handbook that Jasione 

 montana is one of the hosts of this species is entirely without corroboration 

 and is probably due to an error in the determination of the plant : the 

 statement is copied from the notice in Berk. Ann. Xat. Hist. ser. 2, v. 

 462 — " On Jasione montana, Lampeter, J. Jtalfs." Fischer mentions that 

 he has occasionally met with one-celled teleutospores, which I have not 

 seen. 



Distribution : Central Europe.

Teleutospores. Sori roundish, united in large clusters, often 

 confluent, on discoloured spots on the leaves, or on the petioles 

 forming elongated swollen patches, long covered by the silver- 

 grey epidermis, at length naked, pulverulent, dark-brown ; 

 spores ellipsoid to broadly fusiform, rounded or attenuated 

 above, with a conspicuous colourless papilla, mostly rounded 

 below, scarcely constricted, smooth, chestnut-brown, 28 — 42 x 

 14 — 21 ^ ; pedicels hyaline, delicate, short, deciduous.
