734 CONNECTICUT EXPERIMENT STATION REPORT, 



to this disease on a variety of privet called italicum, which was 

 imported from France in the spring previous to our examination 

 in the fall of 1910. The fungus causes diseased areas on the 

 stem and branches, which are not very conspicuous, being slightly 

 sunken and a different color, but when these cankers entirely 

 girdle the branches, the leaves and finally the whole branch above 

 die, and the trouble becomes very evident. The injury at this 

 place was quite noticeable, through the dead branches and one 

 or two dead bushes, but probably the shock of transplanting 

 may have weakened the plaftts so that the trouble was more 

 conspicuous than it would be under more favorable conditions 

 for the host. 



When Atkinson originally described this fungus (Bull. 49, 

 Cornell Exp. Sta.) in 1892, he said nothing about the injury 

 to the host, and we have seen no reference where it is said 

 to have caused conspicuous injury, though it seems to be capable 

 of it. Atkinson obtained cultures of the fungus, described the 

 conidial stage, and suggested that it had a mature stage, which 

 his student, Miss Stoneman, later described (Bot. Gaz. 26: 

 101. 1898) as belonging to the genus Gnomonwpsis, now known 

 as Glomerella. 



Cultures of the fungus were easily obtained by the writer 

 from the cankers, and these produced both the conidial and the 

 asco stages. Miss Stoneman notes the presence in the cultures 

 of setae connected with the conidial stage, but did not find these 

 on the host. The writer, however, found some of these setae 

 with the conidial stage on the host. 



EASPBEEEY, Rubus strigosus. 



RUST, Puccinastrum arcticwn var. americanum Farl. This 

 rust, which was described a few years ago by Professor Farlow 

 (Rhodora 10: 13. 1908), has ordinarily been confused with 

 the uredo stage of Kueneola albida, as, like that species, it forms 

 very small orange outbreaks on the under side of the leaves. 

 Microscopically, however, the two are quite distinct. The uredo 

 stage was sent to the writer from Stamford in September, 1909, 

 on cultivated raspberry, this being the first time it has been 

 found in the state. It apparently did little harm to its host. 

 The secial stage is unknown, though it may be Peridermium 

 balsameum on the balsam fir.
