 Sept.-Oct. 



Of a soft gelatinous consistence approach- 

 ing that of a Tremella. Pileus fan-shaped, 

 or rounded in front, attenuated behind so 

 as to make a short spurious stem. In an 

 early stage it is decurrent at the point of 

 attachment. The surface is of a bistre- 

 brown, uneven with frequent depressions, 

 and rough at first with little points, but 

 at length nearly smooth. The hymenium 



is either pure white or shaded with a delicate blue tint, the spines straight, of 

 moderate length, and very delicate. The plant shrinks much in drying. 

 M.J.B. Of singular beauty, almost translucent with steel-blue tints shading 

 into violet, while the spines are of a pure soft white. Spores round, somewhat 

 irregular, white, 2 mk. W.G.S. Name gelatin a, jelly. Gelatinous. Pers.
