It may be added^ for the benefit of any who wish 

 to pursue the study of this interesting branch of 

 Cryptogamic Botany, that the leaves of the plants 

 containing the parasitic fungi now noticed may be 

 collected and preserved by drying between folds of 

 blotting-paper_, or the leaves of a book, and will 

 retain their character, with the exception of colour 

 in the orange forms, so as to be eligible for examina- 

 tion at any period of the year for twenty years to 

 come. Each species, when dry, may be transferred 

 to an old envelope, and labelled outside with the 

 name, date of collection, and locality; and one 

 hundred such envelopes will constitute a miniature 

 herbarium in a very small compass.
