132 THE POLYPORACEAE OF WISCONSIN. 



nate, white and stuffed, then convex, depressed around the stem, ochra- 

 ceous-yellow or brownish-yellow and sometimes separating from the 

 stem by the expansion of the pUeus ; stem equal or slightly tapering up- 

 ward, reticulated either wholly or in the upper part only, colored like 

 the pileus or a little paler, sometimes slightly f urf uraceous ; spores 

 subfusiform, brownish-ochraceous, 12.6 to 18 microns long, 5 to 6 mic- 

 rons broad. 



Pileus 8 to 16 cm. broad ; stem 5 to 10 cm. long, 12.5 to 25 mm. thick. 

 Thin grassy woods. 



Eare. Collected in the margin of the woods around Hemlock Lake 

 near Crandon. 



The largest specimen measured about 10 cm. in diameter ; the stipe 

 was 9 cm. long and 1.2 cm. thick. The pileus was brownish-red, slightly 

 tomentose, convex, thick ; the flesh white. The tubes convex, depressed 

 around the stem, in one specimen they were separating from it. The 

 stem is firm, large, paler than the pileus, especially near the top, reticu- 

 lated near the top. 



The distinguishing characters of this species are the whitish pores, 

 separating from the stipe and the reticulated stem. 



Boletus variipes Peck. 



Pileus convex or nearly plane, soft, dry, squamulose, punctate-squa- 

 mulose or minutely tomentose, grayish or pale grayish-brown, some- 

 times tinged with yellow or ochraceous, flesh white, unchangeable ; tubes 

 convex or nearly plane, slightly depressed around the stem, at first 

 white, then greenish-yellow, their mouths small, subrotund, ochraceous, 

 stuffed when young; stem firm, reticulated, whitish or pallid; spores 

 oblong-fusiform, ochraceous-brown tinged with green, 12.6 to 15 microns 

 long. 5 microns broad. 



Collected near Oakfield. The specimens probably belong to the vari- 

 ety pallidipes. The largest was. 12 cm. in diameter; the stipe 10 cm. 

 long and 1.2 cm. thick. 



The pUeus was plane, grayish-brown minutely tomentose. The stipe 

 short and bulbous at the base, pale brownish, firm somewhat fibrous in 

 texture, not at aU reticulated near the base. 



O. Calopodes. Stipe tJiick, lulbose, typically reticulated; tubes ad- 

 nate, not red.
