130 NEW OR NOTEWORTHY FUNGI. 



of ffij. compositarum, is distinguished from the (E. taraxaci K. et S. 

 Avhich is stated to be a stage of P. si/Ivatica Schr., by the very 

 numerous peridia, not seated on discoloured spots, " spreading 

 over the whole leaf, and generally collected into numerous little 

 clusters with single ones scattered between them " (Grev. L c). 

 Specimens of both, collected by Mr. H. T. Soppitt, now lie before 

 me. Mr. Soppitt has experimented with (E. Grevillei, and ia 

 convinced that it is the I. stage of P. variabilis. He generally 

 finds them both together, the upper leaves^affected by the (Ecidium, 

 the lower ones by the Puccinia ; after laying leaves affected with 

 the (Ecidium on a dandelion plant, covered with a bell-glass, in his 

 garden, he found the Puccinia appear in about fourteen days. Mr. 

 Soppitt's specimens of (Ecidium Grevillei are from Grassington, 

 Yorks., August. Dr. AVinter's view of uniting P. variabilis with 

 his P. Jiosculosonwi (compositarum) is inexplicable.

 (1869) p.p. Distinguished from the preceding by the peridia being 

 collected into rather large, dense, amphigenous clusters, seated on 

 a coloured (often purple) spot, with usually about three or four 

 clusters on each leaf. It resembles those (Ecidia which were 

 formerly embraced under the general idea of (Ecidium composi- 

 tarum Mart.

Cups collected in crowded irregular clusters, hypo- rarely epi- 

 phyllous, yellowish, seated on a slightly thickened spot, hemi- 

 spherical, then pierced by a small pore at the apex, at length 

 bluntly conical, with a small irregular aperture, destitute of a 

 proper peridium. Spores irregularly roundish, obovate or poly- 

 gonal, pale orange, averaging 18-25 /x long, 20 /^ thick. 



II. Pustules in small clusters, small, round, pale, soon naked ; 

 spores roundish, pale golden brown in mass, faintly aculeate, with 

 unusually large thickenings round the 1-4 germinal pores, 

 averaging 18-20 fx.. 



III. Pustules scattered or in small clusters, minute, roundish 

 or elliptic to linear, darkish brown ; epidermis persistent, bowl- 

 shaped; spores elliptic or oblong, scarcely constricted, rounded 

 above and below, on very short deciduous pedicels, 26-44 fx
