OCHROPSORA 329 
AKcidia on leaves of Pinus silvestris; uredo- and teleutospores 
on Campanula glomerata, C. latifolia, C. rotundifolia, C. Tra- 
chehium, C. turbinata, end of July—October, not uncommon ; 
sometimes abundant on cultivated species of Campanula, in 
both uredo- and teleuto-stages. (Figs. 246, 247.) 
Some of the forms on the various species are separated by Klebahn as 
biologically distinct, but the specialisation is not in any case sharply fixed 
(Wirtswechs. Rostp. pp. 365—9). C. Campanulae is also recorded, in 
other countries, on many other species of Campanula and on Phyteuma 
and Specularia. In North America the xcidia are found on Pinus rigida 
but, as in this country, are much less common, or at least less frequently 
observed, than the spore-forms on Campanulaceae. On C. rotundifolia, 
this species and Puccinia Campanulae may be found in company. 
DisTRIBUTION: Europe, North America, China, Japan, East 
Indies. 
OCHROPSORA Dietel. 
Aicidia with cup-shaped peridium. Uredospores solitary, 
on pedicels. Teleutospores united loosely into waxy crusts, 
club-shaped or cylindrical, not thickened above, dividing as 
they mature into four superimposed cells. 
This genus is not closely allied to Coleosporiwm. It is, 
indeed, doubtful whether the character upon which the Coleo- 
sporlacee are united into one group, viz. the internal basidium, 
is really an indication of close affinity. There can be little 
doubt that Chrysopsora, which also has an internal basidium, 
belongs to the Pee and not to the Coleosporiacez.
