Mr Greville on tJie Genus Erineuni. 73 
trees, that the vine is the only exception at present known. 
Among them, therefore, are we to look for new species ; and the 
American botanist would find his labour amply repaid by an 
attentive search through his varied and splendid forests. In 
our own country, several known species of this genus remain to 
be detected, and, in all probability, many new ones. Our native 
botanists may rest assured, that, from the shortness of the period 
which has elapsed since the study of the minute fungi has been 
prosecuted in this island, no conjecture can be formed as to the 
' extent of its riches. 
The only Orders, on plants of which, species of Erineum have 
been found, are, Amentace^, Rosacea (Pomaceve), NuciX- 
LACE^, Tiliacej:, Sarmentace^, and Acerace^e. Of these 
the first contains trees the most favourable to the production of 
Erineum.

frequently into rose-red, and finally into a deep fulvous colour.

*f* Persoon, in his Traite sur les Champignons comestibles^ has a few observations 
on this genus, which he considers among les moisissures, very unjustly I think ; for, 
though it may come next to them in a system, it does not by any means follow 
that it is produced by the same cause, or under the same circumstances. He alsd 
mentions the necessity of dividing Erineum into two or three genera ; but, from 
the species at present known, I do not perceive how he can find sufficiently natural
