NEW OR ORITICAL BRITISH FUNGI 153 
new species of Puccinia, described by Sydow as pew itic upon 
Carduus pyonenpnar L.—P. galatica Syd. I should consider 
P. cardui-pycnocephalt Syd. and P. galatica Syd. as representing 
the two poles ie one species, rather than as two distinct species 
parasitic on the same species of host-plant. 
The following is Sydow’s diagnosis of P. galatic 
Teleutospore sori occurring on both surfaces of fe leaf, not 
forming discoloured mace se Rise or gregarious, minute, - 
becoming pulverulent. Telewtospores elliptical, ends rounded, oe 
not thickensd, pp slightly constricted at the median septum, 
dusky brown, epispore about 3 » thick, delicately punctate, 30-45 
xX 22-28 p, pedicel hyaline, stendae up to 30% long. Uredospores 
are found mixed with the teleutospores, pe ge to sy

ie this country the present species has previously been 
cluded under Puccinia Sawifrage Schlecht., from which it differs 
in having the teleutospore warted instead of striate, and in other

country. It differs from S. Saxifrag@ in the smaller teleutospores

of Saxifraga mutata L. and S. oppositifolia Lapeyr. in Norway
