By A. DeBary. Translated by Henry i’, Garnsey, M. A; revised

A faithful and adequate translation of this invaluable work on fungi 
and fungoid plants places the important facts pertaining to their physi- 
ology, structure and classification within easy reach of every English 
botanist. A feature that characterizes the work above all others on the 
subject is the broad and philosophical treatment, giving not only a con- 
nected view of the whole field, but a systematic arrangement of the sub- 
ject matter based upon ample knowledge and sound deductive reasoning. 
The title indicates the scope of the work, the lichens being included 
with fungi. The course of treatment for the fungi is as follows: general 
histological characteristics of hyphe and growth forms; forms of the my- 
celium ; formation and dissemination of spores; systematic and compar- 
ative account of the several groups, the principal ones being Perono- 
Sporew, Saprolegnieze Mucorini, Entomophtl ,Chytridiez, Ustilaginee, 
Ascomycetes, Uredinez: and Basidiomycetes, covering over 200 pages; 
Spores and their germination; conditions of growth; and parasitism, in-
