ON TWO HYMENOMYCETOUS FUNGI. 201 
ant-hills, differing altogether in habit from any European 
genus, and several other forms, either more or less allied to 
those which have long been recognised, or quite unlike 
both in habit and character. It is to two of the latter 
that the attention of the mycologist is now directed, pre- 
senting as they do a most curious combination of characters 
and highly interesting matter for reflection as regards affinity. 
One of these has already been shortly characterised by 
Kunze,* from whom I have received a beautifully-executed 
sketch and a portion of the hymenium, which leave no doubt 
asto the identity of my plant with his. The other, as far as 
I can discover, is altogether new to science. Both form part 
of the rich collection of Sir W. J. Hooker, by whom they 
have been kindly placed in my hands. 
I shall proceed at once to the characteristics of the genera, 
Teserving my remarks on their affinities to the close of the 
memoir,
