146 THE POLYPORACEAE OF WISCONSIN. 



above the annulus, red, or red with yellow stains below; spores pur- 

 plish-brown, 12.6 to 15 microns long, 6.3 to 8.2 microns wide. 



Pileus 5 to 12.5 cm. broad; stem 8 to 12.5 cm. long, 8 to 12.5 mm 

 thick. Thin woods in swamps. Specimens of this species were col- 

 lected near Algoma in tamarack swamps by Mr. B. 0. Dodge, near 

 Crandon in a tamarack and spruce swamp by myself in August, 1905, 

 and at Elkhart Lake. About a dozen specimens were growing out of 

 two tussocks having an area of about 4 square feet. A few days after 

 they had been gathered another crop was growing at the same 

 place. The largest specimen was 7 cm. in diameter; the stipe 7 cm. 

 in height and 7 mm. in thickness. 



The pileus was very viscid, substance soft, red with yellow cracks, be- 

 coming tomentose, grayish-red, scaly or squamose; flesh yellowish, 

 slowly becoming duller when bruised. 



The distinctive feature of the species is the reddish-gelatinous mem- 

 branous, translucent veil which soon breaks down leaving a small gela- 

 tinous annulus and sometimes leaving the margin fringed or appendicu- 

 late. When mature, the specimens look very much like old specimens 

 of Boletinus pictus in color, from which, however, the species is quite 

 distinct. 



Boletus albus Peck. 



Pileus convex, viscid when moist, white, flesh white or yellowish; 

 tubes plane, small or medium, subrotund, adnate, whitish, becoming 

 yellow or ochraceous; stem equal or slightly tapering downward, both 

 it and the tube glandular-dotted, white, sometimes tinged with pink 

 toward the base; spores ochraceous, subfusiform 7.6 to 8.9 microns 

 long, 4 microns broad, stem 4 to 7.5 cm. long, 6 to 12 mm. thick. Woods, 

 especially pine and hemlock. 



A group of this peculiar little Boletus was found near Hazelhurst in 

 August 1904 growing out of some very rotten hemlock or pine. The 

 largest pileus was 4 cm. in diameter, 1 cm. thick ; the tubes 3 mm. long ; 

 the stipe 7 cm. long and 4 mm. thick. 



They grew in bunches but not cespitose; the pilei were very viscid 

 convex, the cuticle separable from the snow-white flesh. The pores were 

 white, adnate, short, glandulose, excreting a dirty-milky, astringent 

 fluid which dries on the mouths and stem giving rise to the grayish- 

 white glandules. The stem is white, tapering upwards. The tubes and 

 flesh sometimes change to pink very slowly, where bruised. When dry 

 the specimens have a dull pinkish-brown color.
