A COLLECTION OF ECONOMIC AND OTHER FUNGI 

 PREPARED FOR DISTRIBUTION. 



By Flora W. Patterson, Mycologist. 



INTRODUCTION. 



An examination of this list will show the collection to be geograph- 

 ically very limited. It is hoped by the method now proposed to 

 interest a large number of botanists whose collections may help ours 

 to become more general in its nature and enable others to materially 

 enhance the value of their herbaria at small expense. Advanced 

 students in agricultural colleges may, under the directions of their 

 instructors, be able to collect and contribute valuable material that 

 will thus be made available to other workers and at the same time 

 acquire a choice nucleus for their own herbaria. This plan will also 

 accomplish the purpose of an exchange bureau for fungi which will 

 be free from the awkward limitations of the usual exchange bureau. 

 It will be easily adapted to the individual needs and circumstances of 

 all classes interested. 



Much unidentified material is at hand to be worked up which, 

 together with what is expected to be received in response to this issue, 

 will warrant the publication of an additional catalogue as soon as the 

 work can be accomplished. The attempt will be made in the future, 

 as has been with this distribution, to verify all determinations, and 

 no effort will be spared to make the collections as authentic as pub- 

 lished sets of exsiccati. Species have been carefully compared with 

 their types when such were available. Duplicates of all these speci- 

 mens may be examined in our herbarium. 



The general arrangement and the nomenclature of the fungi are in 

 the main that of Saccardo's S} T lloge Fungorum, and the nomenclature 

 of the hosts is from Farlow and Seymour's Host Index and Hooker 

 and Jackson's Index Kewensis. Names marked with an asterisk (*) 

 are from the Index Kewensis. The above works are the ones used 

 for general reference and the arrangement of our herbarium. No 

 attempt has been made to keep strictly up to date with the rearrange- 

 ment of groups by recent monographers, as an exchange like the 

 present may much more appropriately adhere to standard works 

 which are probably accessible to all.
