Stipes (b) ; scrape out the gills, and, 

 where the fungus is very fleshy, re- 

 move also a portion of the solid part 

 of the pileus. The vertical section, 

 and the respective portions of pileus 

 and stipes, are then to be placed in 

 blotting-paper, and submitted to 

 pressure, as is usual in drying plants. 

 It is, however, advisable to expose 

 them to the air for a short time, in 

 order to wither them, and also to 

 apply the pressure at first gently, as 

 they are otherwise liable to split and 

 crack. If the fungus is of a succulent 

 nature, M. Klotzsch recommends 

 drying them within the influence of 

 the fire, and changing the papers 

 several times a day. When dry, the vertical section, with 

 the pieces of stipes on which are to be placed the respective 

 portions of pileus, may be glued upon 

 paper, and the whole will give a very 

 good idea of the general appearance 

 of the fungus, (fg. 30.) 



Where a sufficiency of plants of a 

 species occur, sections may be made 

 of them in their different stages of 

 growth, showing the various degrees 

 of developement. {fg, 31.) 



The very vivid colours of some 

 jFungi (^garicus emeticus and others), 

 are, in specimens dried in this man- 

 ner, beautifully preserved, as well as 

 the forms of some of the most fragile 

 and delicate species. 

 The advantage which this mode of preservation possesses 

 over all others, by enabling us to place 

 the specimens in almost as little space as 

 other plants in our herbaria, renders it 

 worth the notice of all botanists. 



I trust I have made myself intelligible ; 

 but any one desirous of farther information 

 would doubtless find it in M. Klotzsch's 

 paper. Not having the Botanical Mis- 

 cellany at hand, I can only speak from me- 

 mory; but I think the paper will be found 

 in the fifth or sixth number of that work
