REPORT OF THE STATE BOTANIST I906 45 



to the mycologist. It occurs in our State on Long Island and so 

 far as known is not found elsewhere within our limits. Its viscid 

 cap is 2-4 inches broad and its stem about as long and 4-6 lines 

 thick. It grows both in thin woods and in open places and occurs 

 during July and August. According to the old rule, which pro- 

 nounced all species of which the broken flesh assumed a blue color 

 to be unfit for food and dangerous, this species should be rejected. 

 But this rule must have its exceptions. I have eaten of this boletus 

 without harm and one of my correspondents writes that he has 

 eaten four caps of it at a meal and considers it an excellent species.

RUGOSE CAP BOLETUS 



State Mus. Bui. 94, p. 20, pi. Q, fig. 6-10. 



The rugose cap boletus is well marked by its yellowish ochraceous 

 cap which is irregularly uneven by unequal and variously shaped 

 pits or depressions in its surface. It is sometimes slightly tinged 

 with red or orange and occasionally embellished with small areolae 

 formed by cracks in the surface. The surface is viscid and siiining 

 when moist and the flesh is white or whitish. The tubes are at first 

 closed but they soon open, are minute, round and yellow, becoming 

 darker with age. The stem is solid and firm in texture, often 

 marked with elevated longitudinal lines or ridges and dotted with 

 numerous points which are variable in color, being either pallid, 

 brownish or yellowish. The cap is 1-3 inches broad, the stem 2-4 

 inches long and 4-8 lines thick. The plants grow in thin woods and 

 may be found in August. They have been found on Long Island 

 but not in other parts of the State. In preparing them for the table 

 it is well to peel away the cuticle and the tubes and discard the stetn. 



NEW YORK SPECIES OF HYGROPHORUS 

 Hygrophorus Fr. 



Hymenophorum continuous with the stem, descending unchanged 

 into the trama ; lamellae acute on the edge, clothed with a hymenium 

 changeable into a waxy mass, not membranaceous ; spores globose 

 elliptic or ovoid, white. 



Terrestrial putrescent fungi with a viscid or moist pileus. 



The waxy character of the hymenium is the chief distinguishing 

 character of the genus. The lamellae are usually thick, distant or 

 subdistant, and their hymenial surfaces somewhat separable from
