abundant than in other fungi. Extracts with petroleum-ether gave fats

Mycological Notes.* — C. G. Lloyd prints No. 18 of these papers, 

 with photographic plates of the plants described. The genera Trichuster, 

 Lanopila, LasiospJucra, Schizostoma, Broomeiu, Buttureopsis, and Gyro- 

 phragmium are passed in review. The latter genus is, he considers, 

 identical with Polyplocium, and is not a true gastromycete. Notes are 

 added on various other subjects, on micro-photographs, an albino 

 Geaster, a colourless form of G. triplex, etc. He has also issued recently 

 " The Lycoperdaceae of Australia, New Zealand and neighbouring 

 Islands,"! with illustrations of the type specimens he has found in the 

 museums of Europe and elsewhere. 



Effects of Copper on Fungi.} — W. Ruhland has studied the question 

 as to the exact effect of Bordeaux mixture when used as a spray on the 

 leaves and on the fungal parasites. In the latter case he considers that 

 the excretions of the hyphas due to metabolism dissolve the copper and 

 thus induce fatal poisoning. Experiments with spores of Aspergillus 

 niger, Botrytis vulgaris Cephulothecium, roseum, and Cluster osporium gave 

 similar results. In some cases washing the poisoned spores with a weak 

 solution of hydrochloric acid restored their vitality. 



Nomenclature of the Organs of Pyrenomycetes and Deuteromy- 

 cetes.§ — G. B. Tra verso goes carefully through the different groups and 

 genera of fungi in these two classes, explaining and exemplifying the 

 terminology of the many forms to be found in the fruiting bodies and 

 in the spores. He adopts the method of classification followed by 

 Saccardo and by almost all mycologists, that of arranging the genera 

 according to the type of spore. He gives an index of the Latin terms 

 used in his paper. 



Sylloge Fungorum.|| — P. A. Saccardo has brought his great work 

 well up to date in this latest issue, which includes all recently published 

 species from Hymenomycetes to Laboulbeniacere, S225 species in all. 

 There are 17 species described for the first time in this volume. A 

 Bibliotheca mycologica by G. B. Traverso is added. There are also 

 host or habitat, generic, and species indices. The volume containing 

 Discomycetes and Deuteromycetes is promised early in 1906. 



Physiological Anatomy of Fungus Galls.! — H. Bitter von Gutten- 

 berg has studied the alteration of tissues or new growths induced by 

 fungus parasites in the host plant. The fungi he examined were species 

 of Albugo, Exouscus, Ustilugo, Pucciniu, and Exobasidium. He describes 

 the galls formed by the fungi and the process by which the cells change 

 their function or are destroyed altogether.
