This species belongs to Group 2, Tribe Excentrici and is 

 related to P. lignatilis, from which it may be separated by its 

 glabrous pileus, adnexed lamellae, more glabrous elongated stem 

 and by the absence of a farinaceous odor. 



Lactarius hibbardae Peck n. sp. 



Pileus fleshy, broadly convex or nearly plane, with or with- 

 out an umbo, slightly zonate, dry, minutely tomentose or 

 pubescent, grayish brown tinged with pink, darker and smoother 

 in the center, even on the thin and sometimes w^avy margin, 

 flesh whitish, odor weak or none, milk white, taste acrid ; lamellae 

 thin, narrow, close, adnate, some of them forked, cream color ; 

 stem equal or slightly tapering upward, stuffed, glabrous below, 

 clothed at the top with a minute whitish tomentum, pinkish 

 white ; spores globose, 6-8 fx broad. 



Pileus 1.5-2.7 cm. broad; stem 2.5-4 cm. long, 3-6 mm. 

 thick. Ground under young pine trees. West Roxbury, Massa- 

 chusetts. October. Miss A. Hibbard. 



The species is related to L. glyciosmus from which it may 

 be separated by the lack of squamules from the pileus. the 

 absence of the very distinct antl peculiar odor of that species 

 and by the different character of the surface of the stem. The 

 plants are sometimes cespitose. The species is dedicated to its 

 discoverer. 



Entoloma suave Peck n, sp. 



Pileus thin, broadly convex, umbilicate, with decurved 

 margin, glabrous, shining, grayish brown ; lamellae moderately 

 close, slightly rounded behind, adnexed, yellowish becoming flesh 

 color ; stem equal or nearly so, glabrous, stuffed, whitish 

 or pale yellow ; spores broadly elliptic or subglobose, even. 6-8 /i 

 long, 5-6 p. broad. 



Pileus about 2.5 cm. broad ; stem about 2.5 cm. long, 2-3 

 mm. thick. On old stumps in swampy places. Ellis, Magnolia 

 and Newton, Massachusetts. November. G. E. Morris. 



This is a very neat and attractive little mushroom, having 

 a very regular glabrous and shining pileus and a beautiful nearly 

 :straight stem. Its peculiar features, which easily separate it 

 from nearly all other species of the genus, are its umbilicate 

 pileus and the even, not angular, spores. 



Leptonia abnormis Peck n. sp. 



Pileus thin convex, broadly umbilicate, glabrous, hygroph- 

 anous, blackish brown, shining and obscurely striatulate on the 

 margin when moist, dark grayish brown when the moisture has 

 escaped, flesh colored like the pileus ; lamellae broad, subdistant,
