ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 329 



classified under Famago vcigans or Capnodium salicinum, but Neger has 

 demonstrated by artificial cultures that quite a large number of fungi, 

 such as species of Dematmm, Cladosporium, Atichia, Gijroceras, etc., live 

 on the honey-dew. All of the honey-dew forms are distinguished by 

 the gelatinous nature of their cell-walls, which imbibe water readily and 

 thus provide protection against prolonged drought. The fungi are so 

 mixed up on the leaves, and have so many formations in common, that 

 they can only be disentangled and classified by pure cultures. A. L. S. 



Mycological Notes. — Three separate parts of the above notes by 

 C. (t. Lloyd (Cincinnati, Ohio, 1917-18, 717-64, 74 figs.) have come to 

 hand. On the frontispiece of each there is a photograph of Frank H. 

 Ames, P. A. Saccardo, and Johannes Rich respectively, with a bio- 

 graphical note appended in reference to each of these distinguished 

 mycologist?. The author describes and criticizes a large and varied 

 number of the larger fungi which he has received from many parts of 

 the world. The illustrations as usual are copious and instructive.

New or Rare Fungi.— R. G. Fragoso {Bol. Hist. Nat., 1918, 18, 

 78-85) has published a paper on microfungi from Persia. They were 

 found on Phanerogams in the collection made by D. Fernando, which 

 had been determined by Carlos Pau. Most of them are parasites, and a 

 considerable number are new species. A. L. S. 



Diseases of Plants. — Tyozaburo Tanaka {MycoJogia, 1918, 10,^ 

 86-92) describes a number of new microfungi which have been found 

 to be injuring theii' host-plants. A Valsa on Paulownia is analagous to 

 chestnut disease in America, and threatens a loss of valuable timber. 



Arthur S. Rhoales {PMjtopathology, 1918, 10, 86-92) continues 

 his account of some unusual hosts of wood-destroying fungi. Thus, he 

 records SchizophyUum commune on Finus virgmiana. On Ginglco bilola 

 he found Folyporus versicolor and F. Mrstitus. Several other hosts and 

 parasites are given. A. L. S. 



Description and Treatment of Plant Diseases. — A. D. Cotton and 

 Others {Board of Agricidture and Fisheries Leaflets). New editions of 

 a numl)er of leaflets have been issued lately embodying new information 

 on the subjects treated, and especially new methods of control. They 

 are : — No. 39, The Control of Pests of Fruit-trees in Gardens and 

 small Orchards ; No. 77, Finger-and-Toe in Turnips ; No. 131, Apple 

 and Pear Scab ; No. 164, Potato-leaf Curl ; No. 193, Dry-rot of 

 Potatoes ; No. 204, Apple Mildew ; No. 262, Tomato-leaf Rust ; 

 No. 312, The "Blossom-wilt and Canker" Disease of Apple-trees. 

 The diseases treated therein are all due to parasitic fungi, and they have 

 been popularly described and well ilhistrated ; great attention is givtn 

 to the means employed to combat the pests. To each leaflet is appended 

 the statement that : " Copies of this leaflet may be obtained, free of charge 

 and post free, on application to tlie Secretanj, Board of Agriculture and 

 Fisheries, 3, St. James' -square, London, S.W.I. Letters of application so 

 addressed need not be stamped." A. L. S.
