56 Thirty-Second Report on the State Museum. 



latter genus to which I have referred it. Our New York species of Paxillus 

 may be tabulated thus : 



Stem central : 



Pileus glabrous or only the margin tomentose P. involutus Batscli. 



Pileus hairy, less than two inches broad P. strigosus Pk. 



Stem eccentric or lateral : 



Velvety-tomentose, hymenium lamellated P. atrotomentosus Batsch. 



Glabrous, reticulated, hymenium porous P. porosus Berk. 



Stem none « P. panuoides Fr. 



Lactarius Indigo Schw. 



This Lactarius appeared in considerable abundance in August, both in Sand- 

 lake and in G-ansevoort. The younger and fresh plants are generally highly 

 colored and distinctly zonate, especially on the margin, but they fade with age, 

 and generally lose their zonate character. The pileus when moist, is smooth, 

 and subviscid to the touch, the stem is hollow and often spotted, and the 

 spores are yellowish. Wounded places become greenish. It belongs to the 

 section Dapetes, so named doubtless because of the edible qualities of its 

 species. The four New York species of this section are very similar in char- 

 acter, and differ but little except in color and place of growth. They may 

 be tabulated as follows : 



Lamellae when young blue, milk blue L. Indigo >Sc7iw. 



Lamellae when young orange, milk orange L. deliciosus L. 



Lamellae when young purplish-red, milk dark red L. subpurpureus Pk. 



Lamellae when young grayish-yellow, milk pale saffron L. Chelidonium Pk. 



The first and last species usually occur on dry soil under or near pine trees ; 

 the second and third prefer damp soil in and about swamps and among mosses. 



Lactarius sordidus Pk. 



A notable variety occurs in Sandlake. It has a hairy pileus and a green- 

 ish stem. The hairs of the pileus are of a brownish-green color, and toward 

 the margin they separate in tufts or squamules. The pileus, as well as the 

 stem, is more highly colored than in the typical form. It may take the name 

 var. hirsutus. 



Lactarius aquifluus Pk. 



The agreeable aromatic odor, which is present both in the fresh and in the 

 dried plant, is similar to that of L. glyciosmus. 



Russula fcetens Pers. 



The odor of this plant as it occurs with us is not usually fetid or unpleasant. 

 It resembles the odor of cherry bark and might aptly be termed amygdaline. 

 The lamellae are rarely forked and frequently they are quite as equal as in 

 species of the section Fragiles. In this respect it violates the characters of 

 the section Heterophyllae in which the species is placed. It is doubtless this 

 form to which Dr. Curtis gave the name Russula amygdalina. But our 

 plant is scarcely a distinct species, for it does occur with numerous short 

 lamellae intermingled with the longer ones, and the same peculiar odor has 

 been attributed by one writer at least to the European R. fcetens. 



Boletus spectabilis Pk. 



This rare species occurs near Indian Lake in Hamilton County. It was 

 discovered in North Elba in 1869, since which time I had not met with it'. 

 It constitutes with B. pictus and B. paluster a natural group of allied species. 

 When young the tomentum in all of them covers the whole pileus.
