Assistance and Investigation 
Dr. Marshall A. Howe, Curator, has had charge of the 
collection of algae and also that of the hepatics, and has con- 
tinued his studies of the marine algae of the West Indian 
region. In collaboration with Dr. M. Foslie of Trondhjem, 
Norway, he has published during the year two papers on 
algae belonging to the family Corallinaceae. One of these, 
‘¢New American Coralline Algae,” with 14 plates, appeared 
in the Garden BuLLETIN; the second, on ‘* Two new Coral- 
line Algae from Culebra, Porto Rico,” with 4 plates, was 
published in the Bulletin of the Torrey Botanical Club. 
The month of March was devoted to explorations in Porto 
Rico, in company with Dr. and Mrs. Britton, and in Decem- 
ber he went to Jamaica to collect and study the marine algae 
of that island. Dr. Howe has continued to edit Zorreya and 
has had a share in the work of instruction in nature study 
carried on by the Garden in connection with the public 
schools of the city. 
Dr. W. A. Murrill, First Assistant, has cared for the my- 
cological collection. In addition to the regular routine work 
connected with this collection, he has determined and reported 
upon about three thousand specimens of fungi sent in from vari- 
ous parts of this country and of Europe. He spent the summer 
studying type specimens in several important groups of the 
higher fungi at the principal mycological herbaria of Europe. 
A very serious disease of the native chestnut, epidemic about 
New York City, has been investigated and published upon 
by him during the year. His work upon the Polyporaceae 
of North America is now nearly complete and will soon be 
in shape for publication. 
Mr. R. S. Williams, Assistant Curator, has been occupied 
in remounting and arranging the entire lichen collection, and 
at the same time incorporating with it the large duplicate set 
of lichens of the Leighton collection recently received from
