Hym. Eur. p. 618. 1. T. gelatinosum Pers.—Pileus glaucous-fuscous, gelatinous, tremu- lous, dimidiate, somewhat stipitate, covered with small pimples. Spines soft, glaucous. Extremely variable in form, stipitate (on the ground) and sessile. On fir, trunks and sawdust. Rare. 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. 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. Name—gelatin a, jelly.
