SOME PRESENT DAY ASPECTS OF MYCOLOGY. 



The British Mycological Society may legitimately congratu- 

 late itself upon the impetus recently given to the study of 

 mycology in this country, for its members have been largely 

 responsible for the increased attention now given to this branch 

 of botany. Under the able and energetic direction of the general 

 officers, the Society has greatly increased its membership and 

 has extended its activities with success, so that it is now a 

 very vigorous body, meeting frequently in London or else- 

 where, throughout the year. I am assured also that the efforts 

 of the Society to assist in the mycological education of botanical 

 students, especially in the field, are warmly appreciated. Another 

 activity which has been supported by the Society is the estab- 

 lishment of a collection of pure cultures of fungi in the National 

 Collection of Type Cultures at the Lister Institute, which, it 

 may be hoped, will in time become the premier collection of its 

 kind in the world. The recent establishment of the Imperial 

 Bureau of Mycology under the directorship of Dr E. J. Butler 

 is another indication of the importance which our subject has 

 assumed in the Dominions and Colonies as well as at home. The 

 publication by the Bureau of the " Review of Applied Mycology" 

 is an event of special importance, and all mycologists are 

 grateful for its appearance. 



Mycology is a subject of wide scope, for fungi are aggressive 

 organisms and play a by no means insignificant part in the 

 economy of nature. Our branch of Botany has intimate con- 

 nections with Cytology, Genetics, Protozoology, Medicine, 

 Biochemistry, Plant Physiology and Plant Pathology. Indeed 

 so close is the association between Mycology and Plant Patho- 

 logy that the two are often identified in the minds of the 

 scientific public, and although there are certain differences
