FOURTH REPORT OF THE DIRECTOR I907 75 



The season of 1907 has been singularly like that of 1906 in its 

 unfavorable influence on the mushroom crop. Frequent rains with 

 prevailing low temperature occurred early in the season. These 

 were follo\ved by a long period of dry weather which was exceed- 

 ingly unfavorable to mushroom growth. Notwithstanding these 

 adverse conditions about 25 species of fungi have been added to the 

 list of already known New York species. Of these, seven appear to 

 be new or undescribed. In addition to these, eight species of 

 flowering plants have been added to the State flora, but four of 

 these are introduced plants. One alga, one hepatic moss and 10 

 lichens are among the additions to the flora. Most of these addi- 

 tions are due to the interest and activity of correspondents. Speci- 

 mens of plants of various kinds, representing 125 species not new* 

 to the herbarium, have been collected. These serve to illustrate 

 better and more completely the range and variation of their respec- 

 tive species. A list of the names of these and of those new to the 

 herbarium accompanies this report. 



Tests have been made of the edibility of several species of mush- 

 rooms. Eight of these have been approved and added to the list 

 of edible fungi of New York, bringing the whole number up to 191. 

 Descriptions and colored figures of these w^ill be given in accordance 

 with the plan recently followed. 



In answer to requests for information concerning plants either 

 personally or by letter, 891 identifications of species have been made 

 for 86 applicants. 



Stewart H. Burnham, assistant, has disinfected the collections of 

 1906 which needed such treatment, labeled and arranged them in 

 their proper places, assisted in conducting the correspondence of 

 the office, in the identification of specimens and in giving to inquirers 

 the desired information concerning them. He has continued the 

 work on a card catalogue of the fungi described by the State Bot- 

 anist and prepared a list of these for publication.
