MYCOTHECA UNIVERSALIS. 



No Mycologne of the day enables the student to pursue tlie study 

 thoroughly without the help of dried specimens. The best proof 

 thereof is the great number of works on exsiccated fungi, which 

 appear and increase in number from year to year. However, the 

 compass of all these compilations is comparatively limited, the 

 series containing either isolated classes of fungi, or fungi of 

 different countries only, or, at the utmost, of one part of the world. 

 Works of this kind have never yet been extended to the fungi- of 

 countries beyond Europe, and yet this study is best adapted for the 

 purpose of enlightening the views, of enlarging the insight, and of 

 solving many a problem which now arrests our steps, unable as we 

 are to account for it. All these considerations have stimulated 

 the editor to begin a new work on Fungi-Exsiccates under the title 

 Mycotheca Universalis. 



As is evident from its name, the work is to exhibit fungi from all 

 parts of the world and of all classes of the kingdom of fungi. The 

 editor, already known to Mycologists by his " Fungi austriaci exsic- 

 cati" and "Herbarium mycologicum oeconomicum," will use the 

 greatest exertions to gain for his undertaking collectors in all coun- 

 tries and continents. The assistance of many of the ablest Mycolo- 

 gists has already been secured ; thus for instance the editor has suc- 

 ceeded in procuring the collaboration of the celebrated Dl'. George 

 Winter, of Leipzig, who has engaged to contribute chiefly Ascomy- 

 cetes. Settled and regular contributions have been secured from 

 various parts of Germany, Austria and Hjimgary ; from Great 

 Britain, Switzerland, Italy, Greece, Norway, Denmark, Russia and 

 several states of the United States of North America, together 

 with expectations of contributions from South Africa and Java. 



The arrangement of the work will be similar to the one which 

 has proved satisfactory for years in the works on exsiccated fungi 

 produced by the editor ; viz. : all the specimens are to be delivered 

 loosely wrapped in paper envelopes. Three centuries (by no means 

 more) will be issued yearly. Orders are to be directed to the 

 editor himself; applications being received by each bookseller with 

 an additional cost. 



Every century, ordered from the editor, and upon receipt of the 

 published price, post-free, amounts to 12 Marks German ^ 4 Tha- 

 lers = 7 Florins Dutch = 12 Shill. = 6 Florins (Austrian value) 

 in silver = 15 Francs. 



In the commencement of 1875 the first century is to be 

 issued.
