ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 703 



North American species of Marasmius," and the synopsis to North 

 American species of Heliomyces. Articles on these genera were previously 

 published. 



Field notes * on the Uredinese are contributed by A. 0. Garrett. 

 The species described were collected some thirty miles from Salt Lake 

 City. 



Italian Fungi.f — Teodoro Ferraris publishes a first instalment of a 

 projected list of fungi for Piedmont, which he has been preparing and 

 arranging during the years 11)01-6. He records 289 species, a few of 

 which are new to science. 



C. MassalongoJ states that since the publication of the Veronese flora 

 in 1902, a considerable number of additions have been made to the fungi, 

 and he publishes a list of these, 82 in number. Several are new species, 

 and diagnoses of these are given. 



Plant Diseases.§ — E. Zederbauer describes the canker of pine-trees 

 caused by Dasycypha calyciformis. It enters the tree by wounds caused 

 by injury to the bark or by breaking of branches, etc. Infection appears 

 first in the soft bast, from which it spreads both to the wood and the 

 cortex. 



E. Mead Wilcox || gives an account of diseases that have affected 

 fruit trees in Alabama. He classes them under the plants attacked, 

 beginning with apple, and describing the various rots, cankers, blights, 

 etc. The latter pages of the bulletin are devoted to an account of 

 fungicides, their preparation, and methods of applying them. 



In another paperlf Mead Wilcox takes up the diseases of sweet 

 potato — black and dry rot, scurf, etc. — all due to various forms of fungi. 



A. Stift ** records the damage done to plants in Hungary during the 

 year 1905 both by insects and by fungi. He notes the occurrence 

 of Gymno sporangium Sabiiw, JEcidium Grossularice, and Phyllosticta 

 fragaricola. 



Arsenio Puttemans ft gives an account of the cultivation of lucerne 

 in the state of S. Paulo. It is found that in that region it lasts only 

 three years instead of ten or fifteen years as in the Argentine Republic. 

 The author thinks that its disappearance is due at least in part to the 

 action of various fungal parasites, of which he gives a descriptive list. 

 These are difficult to eradicate, but advice is given as to methods of 

 cultivation that will strengthen the lucerne and render it less liable to 

 disease.
