WARTY AGARIC. 



TAB. XLVIL 



HpHE root, as in the laft fpecies, is a little fwelled, or ap~ 

 ■*• proaching to a bulb-fhape, efpecially while the plant is 

 young; it is furrounded with a large, white, lobed, permanent 

 volva, which emits a number of fibres from its bafe. 



The ftem is firm, folid, upright, cylindrical, of a brittle 

 fubffance, and four or five inches high. 



The curtain is white, tough, foft and dawny to the touch; 

 it feparates from the pileus all round the rim, without being 

 torn, and remains on the ftem. 



The gills are arranged in three feries, but variable in their 

 refpecfive lengths ; they are deep or broad, white, foft, pliable, 

 and numerous. 



The pileus is globular at its firrr. eruption from the volva, 

 and clofely covered with prominent warts, which are not the 

 fragments of any volva, but of a fubffance fimilar to that of 

 the pileus, and grow thereupon ; they are hard, of a firm tex- 

 ture, and on being forced from the pileus will break its furface; 

 they increafe proportionably with the plant in the progrefs of 

 its growth, and at its maturity are eafily feparable therefrom, 

 leaving pale marks on the parts of the furface which they 

 occupied. 



The colour of the warts is a little paler than that of the 

 furface of the pileus, both are of a brownifh dufky moufe 

 colour; the flefh is thick, white, and brittle. 



Grows in woods, about the roots of trees, but is a rare 

 fpecies here. The fpecimen here reprefented, I gathered in 

 the Shroggs, oppofite Birks-Hall. 



It differs from the A. nobilis and A. mufcarius, in that the 

 inequalities on its furface are growing tubercles, and not loofe 

 fragments.
