AGARICUS. 



Crepidotus. adfixed by cottony flocci. Stem obsolete. Gills ventricose, clay- 

 colour, margin whitish. 



On decaying wood. Penzance. 

 Name — after J. Ralfs. B. b' Br. n. 2008. 



Chitonia. 



Series IV. PRATELLI {pratiim, meadow or pasture ground). 

 Spores typically black -purple or fuscous-purple, more rarely 

 fuscous. [It is to be observed that the spores vary in colour 

 according to the colour of the ground on which they are deposited.] 

 There are sterile forms with the gills persistently white {A. obtii- 

 ratus, A. udus). Those species are more deceptive in which the 

 gills continue for a long time white, and even begin to decay 

 before they are discoloured by the spores ; these may be easily 

 mistaken for Leucospori. Fr. Hyin. Eur. p. 277. 



Subgenus XXVIII. CHITONIA.— The universal veil (forming 

 a volva) separate from the pileus. Hymenophore separate from 

 the stem. Gills free. Spores fuscous-purple. Analogous with 

 Ainaiiita and Volvaria. Fr. Hyin. Eur. p. 277. 



No British species. 



Psailota. Subgenus XXIX. PSALIOTA {^aXiov, a ring or collar). Fr. 



Syst. Myc. i. p. 280, Stropharia included. Stem ringed, separate 

 from the hymenophore. Gills free. Fr. Hyni. Eur. p. 278. 



Psaliota corresponds with Lepiota. The gills are rounded be- 

 hind and manifestly free, exactly as in Lepiota. The species grow 

 on the ground, and begin to appear about the end of summer. 

 The larger ones have been more esteemed as food perhaps than 

 any other, and are well known from the common mushroom {A. 

 canipestris\ 



* Edules {edulis, edible). Larger, more fleshy, celebrated under the name of 

 Champignon, 

 ** Minores. Not tised as food, pileus thinly fleshy. 



* Edules. Larger, more fleshy, &^c. 



685. A. Elvensis B. & Br. — Pileus 15 cent. (6 in.) and more 

 broad, somewhat globose then hemispherical, fibrillose, broken
