On Campanula Rapunculus, C. rotundifolia. Not common. June—August. (Fig. 111.) 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. Nat. Hist. ser. 2, v. 462—" On Jasione montana, Lampeter, J. Bait'; Fischer mentions that he has occasionally met with one-celled teleutospores, which I have not seen.
