Romell: Lind’s Work on Rostrup Herbarium 43 
part in the mycological investigation of Denmark,” “ The plan 
of the work.” 
This part gives a most valuable exposition of the history of 
the mycological exploration of Denmark from the middle of the 
seventeenth century up to the present time. The list of contri- 
butors to this exploration is quite large, and biological notes of 
interest accompany each name, while the most important ones 
are treated in detail and the following are illustrated by portraits, 
viz. : E. Rostrup, Th. Holmskjold, G. C. E. von Oeder, O. E. 
Muller, M. Vahl, C. F. Schumacher, A. S. Oersted, J. C. Fabri- 
cius, E. C. Hansen, J. L. Jensen, M. L. Mortensen, P. Nielsen, 
and C. J. Johanson. 
The second or main part of the work (pages 49-550) gives a 
systematic exposition of all known Danish species (3,324 in num- 
ber) of Phycomycetes, Ascomycetes, Basidiomycetes, and Fungi 
Imperfecti. This is, however, no mere list of names. It is a 
critical and thorough revision of these great groups of fungi with 
diagnoses or interesting comments accompanying a large number 
of the species and with many excellent illustrations. Some of 
the species are here published for the first time. 
As to nomenclature, the author says : “ I have followed the 
rules for nomenclature adopted at the International Congress in 
Brussels, in May, 1910, viz. : that Fries ’ ‘ Systema Mycologicum ’ 
should be the starting point for the nomenclature of the fungi, 
except for the Uredinales, Ustilaginales, and Gasteromycetes, 
which date from Persoon’s ‘ Synopsis.’ ” 
The third part (pages from 555 to the end) contains a “List 
of literature,” “ Index of Danish names,” and “ Index universalis.” 
The work is written in English and can be used with advantage 
all over the world. I cannot abstain from strongly recommending 
it to every mycologist. .The price is 20 danish crowns (about 
53^ dollars).
