EXTRACTS OF PROCEEDINGS.

of great trouble to Vine-growers for many years. Dr. M. W ard 

 undertook to examine into the cause. 



Tomatoes diseased. — Mr. Morris showed specimens from the 

 gardens at Chiswick attacked by Phytophthora. As this appears 

 to infect the Tomatoes when growing in the open, it is suggested 

 that whenever possible they should be at once transferred indoors 

 to a warmer and drier atmosphere, as Tomatoes require a warmer 

 climate than the average English summer to ripen properly. 

 This treatment appears to invigorate them, and renders them not 

 only less susceptible to the disease, but has been known to check 

 the further growth of the fungus at once. 



Hetercecismal Fungi. — The following communication was 

 received from Mr. Plowright, accompanied by specimens : — 



Puccinia Festuca, n. sp. — This species occurs on Festuca 

 ovina and F. duriuscula. The ascidiospores occur on the common 

 Honeysuckle. After a long series of unsuccessful cultures upon 

 various grasses and other plants, extending over a period of eight 

 years, I was this year induced to try the effect of placing the 

 spores of iEcidium periclymeni on Festuca duriuscula andF. ovina. 

 In both cultures the Uredo was produced. I also succeeded in 

 producing the iEcidium on Lonicera periclymenum from the 

 germinating teleutospores. The last named are in shape some- 

 what similar to those of P. coronata, with which species they 

 have previously been confounded. The material from which the 

 iEcidium was produced is on the table, as well as the artificially 

 produced uredospores and the recidiospores from which they were 

 produced. 



Puccinia Agrostidis, n. sp. — The ^ecidiospores of this species 

 have long been known under the name of ^Ecidium Aquilegiae. 

 Mr. J. H. A. Jenner was kind enough last August to conduct me 

 to a secluded spot in Abbott Wood, near Lewes, where he had for 

 several years previously found the iEcidium on the Wild Colum- 

 bine. We carefully examined the grasses in the vicinity, and 

 came to the conclusion that the teleutospores probably occurred 

 on Agrostis alba. Material was brought home to Lynn, and 

 from it this year the jEcidium was produced on Aquilegia vul- 

 garis. In May of this year Mr. H. T. Soppett conducted me to 

 a spot on the east shore of Lake Windermere where the /Ecidium 

 Aquilegiae occurs. Specimens were obtained from which both 

 Mr. Soppett and myself produced the uredospores on Agrostis
