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 

 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 couipasa.
