part with some of their moisture, but not so long that 

 they shrivel, are to be placed between dry blotting- 

 paper, and subjected to pressure as other plants, the 

 papers being changed daily till the specimens are per- 

 fectly dry. When this is the case, the central portion 

 or slice and the two halves of the stem are to be 

 fastened upon white paper, together with the respective 

 halves of the pileus upon the top of the latter in their 

 original position. Here will thus be three sections from 

 which a correct idea of the whole plant may be obtained. 

 The volva and ring of such species as possess them must 

 be retained. With care, even the most fugacious species 

 may be well preserved, according to this method. Some 

 of the smaller and less fleshy kinds will not require to 

 have the gills removed. In collecting fleshy fungi, care 

 must be taken that they are not too old, and absolutely 

 in a state of decomposition, or too much infested with 

 the larvae of insects. When this latter is the case, 

 some oil of turpentine poured over them will either 

 drive them rapidly from their holes, or destroy them. 

 Species with a clammy viscid pileus it is better to 

 expose to a dry air or the heat of a fire, before being 

 placed in papers. 



" The separate parts of the genera phallus and 

 clathrus I fill with cotton, keep them for a time 

 exposed to a dry atmosphere, and then, after removing 

 the cotton, subject them to pressure. The same may 

 be done with the large tremelloid Pezizoe" 



In order to protect the specimens as far as possible 

 from insects, it is recommended that they should be
