and the habitat must be observed, whether in woods, fields, road- 

 sides, downs, etc. The odour and taste are also important. 



The accompanying illustration (Fig. 2) shows thechief partsof an 

 Agaric [Agarictis phalloidcs). a is the cap y^ 



{pileus), from which depend at b b the gills ^ 

 (lamellce) ; c is the stalk {stipes), furnished "^^^^^^^JJ^X 

 with a ring {annithts) at d, and a basal 

 sheath at e, being the lower part of the 

 volva. In the earl}' stage of this species 

 the volva enclosed the whole plant, and J^^^'^TZ^ 

 the warts g g on the pileus on the full-grown 

 plant are remains of it. The annulus, simi- 

 larly, is the remains of a fine membrane 

 connecting the edge of the pileus with the 

 stem, which was ruptured by the expan- 

 sion of the pileus. 



A young specimen of Agaricus musca- 

 riiis is shown in section at the base of Fig. 5. 



The gills are free, as at a, Fig. 3 ; 

 adnexed when they just reach the stem, as 

 at B ; adnate at c ; sinuate when they have 

 a sinus, as at d ; and decurrent when they 

 run down the stem, as at e. The pileus is 

 umbonate, as at f, and depressed, as at o.

 very faintly tinted. At present 453 British species of white-spored 

 Agarics are known, of which forty-one are represented by models. 



Sub-genus i. Amanita. — Distinguished by the usually warty 



pileus, white gills free from or just touching 

 the bulbous stem, which springs from a 

 volva. All the species are terrestrial, and 

 grow in woods and uncultivated places. 

 They may be most readily distinguished 

 from the true mushrooms by their occur- 

 rence in woods and not in pastures, by their 

 permanently white gills, and their white 

 and not purple-brown spores. There are 

 sixteen British species of Amanita, of which 

 four are represented by models.
