the present genera. Already Tulasne and some 

 others accord them no place in their system. 

 ' 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 

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

 I 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.
