246 FUNGI. CHAP. V. 



charged in such multitudes and with such force 

 that a piece of white paper put under the frond 

 will soon be found covered with a fine and brown 

 powder. In the genus Boletus this receptacle is 

 the tubes ; in the Mucors or Moulds, it is the 

 globule surmounting the thread-shaped pedicle 

 or stipe ; in Peziza it is the upper surface of the 

 frond only ; and in Clavaria it is the general 

 surface. 



Models of As many of the Fungi are of the most rapid 

 growth and evanescent duration, so they are also 

 of the most tender and delicate contexture, and 

 cannot possibly be preserved in a dried state so as 

 to retain the habit and character of the vegetating 

 plant. Hence some ingenious artists have endea- 

 voured to remedy the defect by means of models 

 in composition. Sovverby's are uncommonly cor- 

 rect, and are certainly well calculated to give the 

 student a general notion of the form and habit of 

 the species ; but from whatever cause it arises, 

 models do not seem to be much in request. Many 

 of the Fungi, however, are also extremely hardy, 

 and of comparatively slow growth, not attaining 

 to the maturity of their respective species in less 

 than a twelvemonth, and thus exposed to the action 

 of all vicissitudes of season. 



Uses. The powder of the Lycoperdons is said to be an 



excellent styptic ; and is remarkable also for its 

 property of strongly repelling moisture. If a basin 

 is filled with water and a little of the powder
