1 22 FETCH : THE GENTJS CHTTONIELLA. 



Assuming that a separate division is required tor the 

 classification of green-spored agarics, the name Ghitoniella 

 must be used to denote those which possess both a ring and a 

 volva ; the genus thus corresponds to Amanita in the Leitcos- 

 porce. Tlie question whether any of the species of Chloro- 

 phyllum are identical with ChitonicUa poderes can only be 

 decided on the spot. That the dried specimens have no volva 

 proves nothing. 



PI. 1 A. Ghitoniella poderes. — Pileus seen from above. Small 

 specimen. One-half natural size. 



PI. 1 B. Chitoniella poderes. — One-half natural size. The 

 black spots on the voiva are particles of earth ; those on the 

 partial veil are brown warts. 



PI. 2, fig. 1, '^ Psalliotatrachodes,''^ Berk. — ^Natural size. 



Fig. 2," Psalliota trachodes " Berk. — Longitudinal section of 

 the specimen of fig. 1 . 



Fig. 3, " Psalliota poderes,^' B. & Br. — Natural size. 



Fig. 4, " Psalliota pedilia,"" B. & Br. — Natural size. 



Fig. 5, " Psalliota pedilia,^^ B. & Bi. — Longitudinal section 

 of the specimen of fig. 4. 



Fig. 6, Chitoniella poderes. — Unexpanded specimen, partly 

 diagrammatic, (a) volva ; (b) upper layer of pileus. 



Figs. 3-5 are faithful drawings of the paintings from which 

 Berkeley and Broome described their species. Figs. 1 and 2 

 are copied from one of Thwaites' paintings which Berkeley 

 named.
