Teleutospores, on C. lanccolatum. much thickened (5—10 ^ct), constricted, attenuated below, smooth, yellowish-brown, 38—56 x 14—21 [jl; pedicels yellowish- hyaline, thick, persistent, as much as 50 [ju long. On Cirsium lanceolatum, Carduus crispus (?). August— October. Not uncommon on the former. (Fig. 96.) This is one of the species in which the upper cell separates from the lower one. It is doubtful if Puccinia Syngenesiarum (Cooke, Handbook, p. 499; Micr. Fung. p. 206) belongs entirely here, as the figure in the latter work (pi. 4, f. 64) does not give the true form of the teleutospore; but the majority of the specimens issued by him under that name are this species. It is very questionable if this species occurs on Carduus crispus, on which it is recorded by Plowright.
