COLLECTING FUNGI AT DELAWARE WATER 
By WILLIAM А. MURRILL 
The New York Botanical Garden 
The writer's first acquaintance with the region about Delaware 
Water Gap was made on the Decoration Day excursion of the 
Torrey Botanical Club, May 29-31, 1917, a brief account of which 
appeared in Torreya for August, 1917. At that time, with the 
help of other members of the Club, 81 species of the more conspic- 
uous fungi were collected. 
Attracted by the variety of soils, exposures, and host plants 
which this region affords, I spent also a vacation of two weeks 
there, August 1—15, 1917, and secured a fairly representative col- 
lection for that season of the year. I hope some time to be able 
to secure the autumnal species. My collections to date include 
about 200 species, most of which are to be found in the following 
list. 
The abundance of a species is indicated by exponents, the 
numerals 7-5 denoting a definite number of times collected and 
the letters n, nn, and nnn meaning "frequent," “соттоп,” and 
" very common," respectively.
