(55) STUDIES AND ILLUSTRATIONS OF MUSHROOMS : II. 515 



send by express, the sender should pay the express charges, 

 except where good material prepared and named for the her- 

 barium or museum is contributed, or where the sender is certain 

 that the material is of value, as in the case of some rare 

 specimens. In all cases where a list of the plants is desired in 

 return, the sender should enclose a number with each specimen, 

 so that the names can be given to correspond with the numbers. 

 All desirable material will be preserved and kept in the her- 

 barium here where it will be available for comparison and for 

 study. For this reason the locality and date of collection and 

 other notes of interest should accompany the specimens. After 

 one has had some experience in the collection of these plants 

 and in noting the important characters their specimens will be 

 of more value. It is possible in this way for collectors to aid us 

 in bringing together material from different sources which 

 should assist in making these studies and illustrations of mush- 

 rooms more comprehensive and of wider usefulness. 



From students of the fungi who have duplicate material in any 

 of the groups, the Botanical Department will welcome contri- 

 butions to the herbarium. Such gifts are certain to be of great 

 usefulness at a center where students come for research. Not 

 only is this branch of botanical study, as well as others 

 emphasized, it is important to consider that mycological study 

 here contributes to, and is supplemented by, other fields of 

 research in related departments, as well as in the work of the 

 Experiment Station, and in that of the newly organized College 

 of Forestry. 



Specimens may be sent to either of the following addresses : 

 PROFESSOR GEO. F. ATKINSON,
