Lister, G., Two new Mxcetosoa. (Journ. of Bot. XLVIII. March 

 1910. p. 73.) 



Further material has shown that the variety alpinum Lister of 

 Physmnini virescens, Ditm. is a distinct species, and it is here na- 

 med P. alpiniitn. A new species from Colorado is also described, 

 Physanini carnetini, which is allied to P. ßavidmn Peck, but dif- 

 fers in the membranaceous sporangium-wall, in the slender flesh- 

 coloured stalks, and in smaller spores. A. D. Cotton (Kew). 



Petch, T., A list of the Mycetosoa of Ceylon. (Ann. roval 

 bot. Gardens, Peradeniya. IV. 4. Jan. 1910. p. 309—371.) 



The author summarizes the work of previous writers , and gives 

 a copy of the records of Mycetosoa in Berkelej^ and Broome's 

 "Fungi of Ceylon", with re-determinations of the species. An exa- 

 mination of the Ce3'lon species in the herbaria of Kew, British 

 Museum, and Peradeniya has reduced the 66 recorded species to 

 52. A brief account is next given of the growth and habits of My- 

 cetosoa in Ceylon, and it is noted that though the majority of the 

 Ceylon species are to be found in Europe there is a marked 

 difference in their relative abundance. Coviatricha obtiisata, Didy- 

 miiini difforme are rare, and PJiysavuni nutans is seldom found on 

 wood. The commonest Ceylon species are Didymium effusuin, D. 

 nigripes, Physarella mirabilis, Heviitrichia serpida, and H. clavata. 

 The greater rainfall and humidity produces two results not evident 

 in Europe, viz:, the greater tendency of the Plasmodium to wan- 

 der and the greater height from the ground, sometimes over 50 ft, 

 at which the species are found. The author has devoted much time 

 to the study of Mycetosoa^ and during the last few years has worked 

 at the Ceylon species and added many records to the flora of the 

 island. In his final list 102 species are enumerated, and critical 

 notes chiefl}^ dealing with the departures from the normal that 

 occur in Ceylon forms are given. A. D. Cotton (Kew). 



Banepoft, C. K., Fungi causing Diseases of cultivated 

 plants in the West Indies. (West Indian Bull. X. 3. p. 235— 

 268. 1910.) 



A complete list and brief descriptive account of all the fungi 

 which have been reported to be injurious to cultivated plants in the 

 West Indies. The fungi are dealt with in the order of their syste- 

 matic Classification. A few unpublished records have been added by 

 F. W. South, Government mycologist, for the West Indies, 

 together with an appendix dealing with the question of the rela- 

 tionship of Trichosphaeria sacchari Massee, to Thielaviopsis ethaceti- 

 ciis Went; and also the nomenclature of certain fungi in group 

 Spliaerioidaceae Phaeodidymeae. A. D. Cotton (Kew).

 Mori Nom. in Kashmire, with notes on other Mulberry 

 diseases. (Memoirs Dept. Agric. India, Bot. Series. IL 8. April 

 1909. 17 pp. 4 plates.) 



Draws attention to a recent outbreak of the disease caused by 

 Coryneum mori Nom. in Kashmir, a pest hitherto onh' known in 

 Japan whence it was described in 1904.
