yellow when bruised, 10-25 cm. across; flesh thick at the 

 disc, becoming thin towards the margin, yellowish when cut ; 

 gills free, broadest in front, rather crowded, whitish, then 

 reddish - brown ; spores elliptical, 6 X 4 /x, stem stout, 

 7-12 cm. high, rather swollen at the base, almost cylindrical 

 above, white, smooth, even, soft in the centre and filled with 

 loose fibres ; ring pendulous, double, the outer membrane 

 more or less torn. 



In pastures, &c., often growing in rings. Northern Island, 

 New Zealand. Australia, Tasmania, South Africa, Ceylon, 

 Europe. 



Closely allied to Agaricus campestris, but known by the 

 pileus becoming yellow when bruised, and the flesh of pileus 

 and stem not changing to brown when cut. Smell strong and 

 pleasant. Edible; preferred by many to the mushroom {A. 

 campestris). In large specimens the pileus is sometimes 

 cracked or scaly, and brownish when old.

Pileus globose, then expanding until plano-convex, dry, 

 silky, floccose, or broken up into squamules, whitish, some- 

 times tmged brown, 6-15 cm. broad; flesh thick at the disc, 

 margin thinner, becoming reddish-brown when cut, as does 

 also that of the stem ; gills free, but close to the stem, pale- 

 pink, then flesh-colour, finally blackish-brown, inclined to 

 deliquesce at maturity ; spores 7-9 x 6 /x ; stem 7-12 cm. 

 long, stout, subcylmdrical, white, stuffed ; ring median on the 

 stem, persistent, more or less torn. 



In pastures, &c. Northern Island, New Zealand. A 

 cosmopolitan species. 



Edible. Known as the " mushroom " in Britain. (See 

 note under A. arvensis). 



14. Agaricus catnpigenus, Berk., Flora N.Z., ii., p. 174; 

 Hdbk. N.Z. Flora, p. 603 ; Sacc, Syll. v., no. 4102. 



Pileus campanulate, rather fleshy, very obtuse, silky, with 

 a few scattered scales, assuming a reddish hue when dry, 

 about 2-5 cm. high; gills rather narrow, narrowed behind, 

 adnexed or slightly adnate ; spores pale red-brown, obliquely 

 obovate; stem 4 cm. high, about 4 mm. thick, incrassated at 

 the base, slightly furfuraceous, with a broadish ring near the 

 top. 



On the ground, among grass. New Zealand. 



This has much the habit of a Lepiota, but the gills are 

 adnexed and the spores pale but decidedly coloured (Berk.).
