AGAEICINI. 



Order I. AGARICINI. 



Hymenium, inferior, spread over easily-divisible gills or plates, 

 radiating from a centre or stem, which may be either simple or 

 branched. — Fr. Epicr.p. 2. Berk. Out. p. 89. 



The followiBg analytical key to the genera of the Agaricini, and the snh- 

 genera of Ajaricus, has been constnicted by Mr. Wortbington G. Smith, 

 F.L.S.j and by permission, we have adoptedit here with his illustrations and 

 tabular view of the sub-genera. 



ANALYTICAL KEY. 



In using the following key, the first and most important point to 

 be determined in naming an Agaric is to ascertain the colour of 

 the spores. The specimens used for study should always be per- 

 fectly fresh, and, if possible, young, as in many species the char- 

 acters, especially of the veil, are evanescent. The habitat also will 

 be found of considerable importance to begmners. The genera are 

 printed in Capitals, and the subgenera in Italics. The numbers 

 prefixed to the subgenera will enable the reader to refer at once 

 to the Plates, where the numbers correspond.
