Dry hard decorticated wood of American aspen, P o p u 1 u s 

 tremuloides Mx. Thompsons Lake, Albany co. May. 



Pholiota rigidipes n. sp. 



Pileus fleshy, rather thin, broadly convex, sometimes slightly and 

 broadly umbonate, obscurely squamulose with appressed hairy 

 brownish scales more conspicuous in the center, pale yellow or buff, 

 flesh white, tinged with yellow next the gills, taste mild; lamellae 

 thin, rather broad, close, adnexed, brownish ferruginous when 

 mature ; stem equal, slender, stuffed or hollow, more or less flexuous, 

 rigid, floccose squamulose below the slight sometimes evanescent 

 annulus, white and pruinose at the top, pallid below the annulus; 

 spores ellipsoid, 8-10 x 5-6 fi. 



Pileus 5-8 cm broad ; stem 5-7 cm long, 4-6 mm thick. 



Among fallen leaves in woods. Constableville, Lewis co. Sep- 

 tember. 



This species is related to Pholiota terrigena Fr. from 

 which I have separated it because of its more slender habit, white 

 flesh, adnexed lamellae and more slender rigid stem. The margin 

 of the pileus in the dried specimen is obscurely striate. 



Phoma amorphae Sacc.

 Kenwood, Albany co. May. S. H. Burnham. 



Phoma bacteriophila n. sp.

 dermis, then erumpent, scattered or densely gregarious, sometimes 

 crowded and covering the whole branchlet, black ; spores obovate or 

 ellipsoid, hyaline, 6-8 x 4-5 fi. 



Canker spots on young stems of white pine. Pin us strobus 

 L. and on dead branchlets which it completely covers. White Pine

The young trees are killed by a bacterial disease and the dead 

 .spots of the trunk and dead branchlets are attacked by this and 

 other fungi.

 covered with a whitish incrustation ; spores straight, cylindric,
