The purpose of this article is to give a general introduction to 

 the subject of poisonous mushrooms and to outline some of the 

 Problems to be solved. A brief paragraph disposes of the edible 

 Discomycetes and then the Hymenomycetes are considered. Eight 

 species of Boletaceae are noted as being poisonous or doubtful. Then 

 twenty species of Agaricaceae are discussed in alphabetical Order, 

 some very briefly others more at length. The Gasteromycetes are 

 mentioned in the concluding paragraph. The paper is illustrated 

 by three Charts reproduced from French Originals. R. J. Pool.

Bien que le parasite s'introduise dans la feuille par la face in- 

 ferieure, on doit continuer ä repandre les bouillies fongicides sur 

 la face superieure, car c'est lä que les spores tombent et germent 

 normalement. Les zoospores gagnent secondairement la face infe- 

 rieure quand la feuille est imbibee uniformement par les pluies 

 prolongees, les rosees et les brouillards. P. Vuillemin.
