be identified. The number of identical species, described under 

 different names, is immense. This evil may be avoided in future 

 if every mycologist, when describing a new fungus, sends a cul- 

 ture to the office of the Association. The author not only is 

 relieved of the cultivation, but every one who is studying kindred 

 species may procure material for comparison. 



" Rather often applications are made to the office, but the col- 

 lection does not grow in proportion to the description of new 

 species. It has often occurred to us that on our requesting a 

 person to send us a culture of a certain recently described fungus, 

 the author was obliged to reply that as the work was passing 

 through the press the cultures were lost. We beg you not to 

 send the new species only but also those of which you have pure 

 cultures and which are not mentioned on our list, published regu- 

 larly in the ' Botanisches Centralblatt/ because many species are 

 asked for which we do not possess. You are requested to tell us 

 whether the species left to our care want frequent renewing. The 

 greater part of our cultures are transferred but once every three 

 months, but many of them want particular care. 



"We beg to state again our terms, which are 3 florins (Dutch 

 money) for non-members and 1.50 florins for the members of the 

 Association."
