been very widely distributed; and the other a small pocket key 

 to the genera of the gill mushrooms published as a chart, which 

 is folded and bound for use in the field. The characters of the 

 genera are shown for the most part by small pen sketches of 

 typical species, and there is a brief illustrated glossary of terms 

 relating to structure. This key may be obtained from The Nor- 

 man, Remington Company, of Baltimore, for one dollar. The 

 great advantage of any chart over a book is the opportunity it 

 gives to compare a specimen at a single glance with every figure 

 on it.

 sidium, Exidia, Tremella, Tremellodendron, Sebacina, Dacry-

" A Critical Study of the Slime-molds of Ontario," by Mary 

 E. Currie, appears in the Transactions of the Royal Canadian In- 

 stitute of Toronto for 191 9. The paper gives interesting descrip- 

 tive and distributional notes of 118 species and varieties, in 29 

 genera ; 47 species and varieties being recorded from Ontario for 

 the first time, 36 being new to Canada, and 5 new to North 

 America. The following were noted as parasites on fungi : Bad- 

 hamia foliicola Lister, B. magna Peck, B. utricularis Berk., Phy- 

 sarum flavicomum Berk., and P. polycephalum Schw. The fol- 

 lowing nine were found at times fruiting on the leaves or stems 

 of grasses or herbaceous plants, and in some cases at least are 

 injurious to these plants: Diachaea leucopoda Rost., Diderma
