 tawny-ochraceous, 10 x 6 /x.

On dung and in rich pastures. Subcaespitose. Closely 

 allied to jB. Boltoni and B. fiavidus ; distinguished from the 

 former by the clear egg-yellow colour of the pileus, which is 

 not darker nor depressed at the disc ; known from the latter 

 by the white stem. 



Bolbitius flavidus. Bolton. 



Pileus 1-2 in. across, glutinous, conical then expanded, but 

 usuallv with the disc a little elevated, maro-in striate and 

 usually split, pale yellow ; gills almost or quite free, about 

 2 lines broad, at first white, then yellow, at length dusky 

 brown, stem about 2 in. high, 2-3 lines thick at the base, 

 slightly thinner upwards, yellow both outside and inside, 

 hollow, veil very fugacious at an early stage, and leaving 

 no mark on the stem; spores elliptical, brown, 10 X 6 /x.

On dunghills, &c. As stated under Bolhitius Boltoni, 

 Fries ; the true species called Agaricus flavidus by Bolton 

 is quite distinct from the species of Fries, the principal 

 points of distinction being that in the present species the 

 pileus is obtuse or subgibbous and not darker at the disc 

 than elsewhere, the free gills, and the plant not becoming 

 dry and pajDcry at maturity, but deliquescing. The following 

 is Bolton's own account. 



The root is small and hard, emitting black-brown fibres. 



The stem is 2 in. high, smooth, largest at the base, hollow, 

 yellow both within and without, and easily splits in yellow 

 shining filaments. 



The curtain is white, extremely light and delicate ; it 

 vanishes in the infancy of the plant, and leaves no mark on 

 the stem. 



The gills are in three series, of a narrow, oblong figure, 

 thin, and tender ; they are at first white, afterwards yellow, 

 and change at last to a dusky brown. 



The pileus at first conical, and covered with a tough,
