EDIBLE FUNGI.* 

 Sheathed Agaric (Amanitopsis vaginata) (Fig. 8). 



The cap is bell-shaped, gradually becoming quite flat, with 

 a slight central boss, edge grooved, mouse-grey or lead- 

 colour, 3 to 5 inches across ; gills persistently white ; stem 

 elongated, rather slender, whitish, the base enclosed in a loose 

 sheath or volva, 4 to 6 inches high. 



This is found amongst grass, in woods, &c, during the 

 autumn. 



It may be distinguished from certain undesirable kinds, 

 which present a somewhat similar appearance, by the per- 

 sistently white gills. 



The aroma is very delicate and is soon dissipated by heat, 

 so that it is advisable to cook this fungus in a covered vessel. 



Scaly Agaric (Lepiota rachodes) (Fig. 9). 



This fungus is closely related to the Parasol Mushroom 

 (Fig. 7), differing more especially in the absence of a boss 

 or umbo in the middle of the cap ; in the shorter, white stem ; 

 and in the flesh instantly changing from white to a reddish- 

 brown colour when cut or bruised. 



* Nos. 1-3 of this series of coloured plates and descriptions appeared in the

 Mushroom) was issued separately in February, 1909.
