140 ENUMERATION OF FUNGI. 
hymenium, which is cracked when dry, and resembles that of 
a Corficium.  * 
l owe the first knowledge of this curious fungus to Dr. 
Montagne, who kindly sent me specimens which were col- 
lected in Guiana. As they were barren, it was almost im- 
possible to form any correct notion as to its affinities, but 
two or three more or less perfect individuals amongst those 
distributed by Dr. Hostmann, show that it is Hymenomyce- 
tous. As Persoon's genus Hypolyssus is altogether effete, 
and its characters are very like those of the plant before us, 
I have thought it advisable to restore it. ‘The hymenium 1s 
perfectly developed in a single specimen only. The genus 
ill come near Craterellus, from which however it differs 
greatly in its solid pileus.

14-3 inches high; stem short, slender, divided above into 
about three main branches, which are repeatedly but irregu- 
larly subdivided; the ramifications, especially the ultimate 
ones which are very slender and acute, more or less divari- 
cate. The axils of the ultimate ramuli are flattened, so that 
they have frequently a palmate appearance.

Cespitose, about 1 inch high; stem very slender, dichoto- 
mous below, irregularly but not very abundantly branched 
above; the ultimate ramuli, which are suberect, rather obtuse. 
Less gelatinous than the last, and of a darker color, with à 
cartilaginous appearance when dry. The present plant has —
