Personal Investigations 
Two parts of North American Flora, containing descrip- 
tions of 606 species of the higher fleshy fungi, 183 of which 
were new, were published during the year. 
The popular illustrated articles on fungi in Mycologia 
have been continued with the aid of colored plates pre- 
pared by Miss Eaton, 16 species having been treated in 
this series during the year. 
The usual routine of herbarium work and the ever-in- 
creasing number of requests for the determination of speci- 
mens have consumed much time. 
Very little field work has been possible. During a vaca- 
tion of two weeks at Delaware Water Gap, I obtained about 
300 specimens and sufficient information for a preliminary 
report on the fungi of that locality. 
Respectfully submitted, 
W. A. Murritt, 
Assistant Director.
