STUDYING oo AMERICAN FUNGI IN

October 1 on the S.S. ‘‘Kaiserin Augusta Victoria,’’ of the 
Hamburg-American Line, arriving in Hamburg October 10 and 
leaving the same day by rail for Copenhagen, Denmark, where 
I made the first stop for the purpose of comparing recently 
collected gill-fungi with older specimens collected in tropical 
America. By careful identification in this way, with descrip- 
tions and field notes at hand, it is possible to build up a new 
collection of much greater value both for representation and 
comparison than the types themselve 
At Copenhagen, I examined the aay or more drawings of 
tropical American gill-fungi made by Oersted, copies of which were 
sent by him to Fries and used in describing many of his species. 
Very few specimens representing these species were found, either 
at Copenhagen or elsewhere. Professor Warming and Dr. Osten- 
feld gave mea hearty welcome, and introduced Messrs. Ferdinand 
and Winge, two of their younger botanists. An excursion was 
made through the very compact and well arranged botanical 
garden, after which I took the small steamer to Malmé, where I 
caught the night express to Stockholm and reached Upsala, my 
next objective point, late in the afternoon of October 12.

its similarity to parts of the Adirondacks. e hills are rugged 
and crowned with Norway spruce and Scotch a against which
