grayish, tinged with flesh color when mature, beconaing diugv or 

 brownish where wounded; stem minutely scurfy, often irregular or 

 flexuous, reticulated at the top, pallid without and within; spores 

 oblong, brownish flesh color, .0005 to .0006 in. long, .00010 broad. 



Pileus 3 to 4 in. broad; stem 2 to 4 in. long, 4 to 6 lines thick. 



Oak woods. Menands. August. 



It belongs to the tribe Hyporhodii. It has the general appearance 

 of B. modest U!<, but the tubes are not at all yellow. It differs from 

 B. alutarius in color and in having the stem reticulated at the top, not 

 scrupose. Its mild taste will separate it from any form of B. felleus. 



Boletus albellus, n. sp. 



Pileus convex, soft, glabrous, whitish, flesh white, unchangeable; 

 tubes convex, free or nearly so, small, subrotund, whitish, not chang- 

 ing color when wounded; stem glabrous or minutely furfuraceous, 

 substriate, bulbous or thickened at the base, whitish; spores brownish- 

 ochraceous, .00055 to .00065 in. long, .0002 to .00025 broad. 



Pileus 1 to 2 in. broad; stem 1 to 2 in. long, 3 to 6 lines thick. 



Woods. Sandlake. August. 



Closely related to B. scaber, of which it may possibly prove to be 



a dwarf form; but it is easily distinguished by its smooth or only 



slightly scurfy stem without any appearance of the colored dot-like 



squamules which are a constant and characteristic feature of that 



species. 



Polyporus flavovirens, B and B. 



Ground in woods. Selkirk. August. 



Our specimens agi-ee vei-y well with the descrii)tion of P. flavovireiis, 

 except that they are smaller and the dry jilant is not tough and 

 librous. They are to this extent doubtful.

Zahrukie. 



Polyporus mutans, n. sp. 



Resupinate rather thick, tough, following the inequalities of thf 

 wood; pores minute, rotund, short, buff-3'ellow or cream color, becom- 

 ing dingy red or dull incarnate where wounded, the subiculum 

 librous," changing color like the pores, the whole plant assuming an 

 incarnate hue when dried. 



Decaying wood of deciduous trees. Selkirk. August. 



Sometimes a narrow, reflexed obtuse margin of a yellowish-brown 

 color is formed. The pores are often oldique. The species appcarH 

 to be quite distinct by reason of its peculiar colors.
