5. P. involutus Fr. Pileus 7.5-12.5 cent. (3-5 in.) broad, 

 ochrey-ferruginous, fleshy, firm, convexo-plane then depressed, 

 for the most part central, at the first pubescent, soon becom- 

 ing smooth, somewhat viscid when moist, shining when dry, 

 obtuse and villous round the margin which is at first closely 

 involute, when more fully grown extenuated and acute ; flesh 

 compact, pallid. Stem 5-7.5 cent. (2-3 in.) long, 1-2.5 cent. 

 (Yz-\ in.) thick, fleshy, solid, firm, thickened upwards, more rarely 

 at the same time bulbous at the base, naked, dingy yellowish, 

 commonly spotted. Gills decurrent, rather broad, branched and 

 forming pores behind, when young arcuate, crowded, pallid, at 

 once spotted when touched, at length extended, ferruginous. 



Commonly large, obese, readily distinguished by the pileus being villous 

 round the very involute margin, by the gills anastomosing and forming pores 

 at the base and being dingy-spotted when touched. Pileus more rarely excen- 

 tric, darker in colour in wet, and paler in dry weather. It varies lobed and 

 scaly. 



In woods. Very common. June-Nov. 



Edible ; highly esteemed in Russia. Spores ferruginous, Fr. ; ellipsoid or 

 sphseroid-ellipsoid or oblong-ellipsoid, 8-16x6 mk. K.; 5x6 mk. W.G.S.

6. P. leptopus Fr. Pileus 4-7.5 cent. (iX~3 in -) broad, fus- 

 cous-yellowish, always excentric or lateral, at length depressed 

 but gibbous in the middle, fleshy, thin, dry, covered with dense 

 down, soon torn up into dense villous scales, which are fuscous 

 or yellowish ; flesh yellow. Stem very short, scarcely reaching 

 2.5 cent, (i in.), somewhat incurved, attenuated down ward s, yellow 

 within. Gills simple behind, decurrent but not anastomosing, 

 tense and straight, crowded, very narrow, yellowish, then darker, 

 but not spotted when touched. 



Changeable in stature and form. A remarkable species, with the habit of 

 P. involutus, from which it is readily distinguished by having the gills simple 

 (not anastomosing) at the base.
