Jall . i9io.] OBISBIMO-ON THE CONNECTION. 5 



circular or irregular groups, each sorus maesuring 0,2-0,5 mm. 

 in diameter ; teleuto-sori, form and arragement like that of 

 uredo-sorus ; teleutospores subcuticular, at first oblong or club- 

 bed and unicellular, at maturity four-celled, outer wall of the 

 apical cells very much thickened, 37-21 fi long, 9-7 f broad ; 

 sporidia ovate or elliptical, 13 ft long, 8 f broad : — I. on the 

 leaves of Pinus densiflora ; II and III. on the leaves of Aster 

 scaber. 



The uredo-sori of this species first make their appearance at 

 the beginning of June and continue to propagate till August, 

 when teleuto-sori begin to appear and which in turn continue 

 their formation till the middle of November. The teleuto-spores 

 germinate immediately without hybernation and attack the 

 pine leaves. As to the relation of Peridermium Pini-Thanbergii 

 to the other Colesporiutn, we must wait the result of another 

 infection experiments, which I wish to carry on further in some 

 future days.
