The appendix is devoted to an interesting account of the following 
fungi imperfect! i-Tonda, Mycoderma, cerevisiw , Monilia Candida ,, M. 
albicans , Dematium pullulans , Oidium schcenleinii , 0. quinckeanum , 0. 
tonsurans , Hormodendron cladosporioides , Cladosporium lierbarum , 
tosporiumbifur cum , Stachybotrysatra , and Arthrobotrys oligospora. The 
book concludes with a list of errata (by no means complete), a list of 
illustrations, and a general index. It is printed in clear Roman type, 
on good paper, and except for the half-paper cover, which does not 
wear well, is, like most German books, well bound. The illustrations 
are especially praiseworthy, not so much for mechanical execution, 
wherein some are inferior, as for the care with which they have been 
selected to illustrate particular features, and the fact that most of 
them have not been hackneyed by repeated use in other books. The 
illustrations are also numerous enough, by the union of many distinct 
figures into one so-called figure, to give a good general notion of the 
whole subject of fungi. 
In several cases there is an omission of important facts which should 
appear in a work of this charatcer, e. g ., Jensen hot water treat¬ 
ment for smut of oats and wheat, or Humphrey’s discovery of cilia on 
the swarm spores of Adilya. Occasionally also there is a slip, e. g ., 
on page 90 the term u epiplasm ”^s attributed to De Bary with a dif¬ 
ferent meaning from that given in his Morphologie, i. e ., He Bary uses 
it for glycogen mass, but it is here used to designate the residual pro¬ 
toplasm in free cell formation, for which DeBary’s own term is u peri¬ 
plasm^ on pp. 386 and 397 the genus Endopliyllum is said to possess 
no teleutospores, but to have secidiospores which germinate with the 
formation of a promycelium and sporidia, all of which might have come 
from a superficial consideration of the arrangement of the spores or 
from a hasty reading of Winter’s description (Pilze I. p. 251), but 
which can scarcely be admitted if we are to attach any definite mean¬ 
ing to the term teleutospores on p. 439 Gymnoascus reesii is said to be 
the only species of the genus, whereas Winter gives 3 and Saccardo 6. 
Such causes for complaint are, however, comparatively few, the bulk 
of the errors consisting of transpositions, slight omissions, incorrect 
numbering of descriptions (e. g ., fig. 74), and wrong cross-references. 
Of the latter there are at least a hundred, a very considerable number 
for a book of reference. Happily, so far as observed, these mistakes 
do not extend to the index, or the references to literature which are 
quite copious. This book was evidently first issued as part of a larger 
work of some sort (Schenck’s Eandbuchf) and then repaged for issue in 
the present form, and the errors are probably attributable to want of 
care in the revision. 
The treatment of the whole subject of conidia and of the special group 
Saccharomycetes is of particular interest, but to readers already familiar 
with De Bary, the chapters devoted to physiology and biology will no 
doubt seem freshest, while to the beginner the 200 pages devoted to
