1486. 1919? Not Tremella vesicaria Bulliard. 
Type: in Herb. Schweinitz. 
Fructifications gelatinous, very soft, growing up from the 
ground and ascending, incrusting and supported by herbaceous 
stems between which the masses are suspended in various forms 
determined by distribution of the supports, often a whitish, 
semi-pellucid membrane, drying hard, horn-like, somewhat 
wood-brown, and more or less veined; basidia longitudinally, 
cruciately septate, subglobose, 12-15x10-12 w; spores hya- 
line, even, 8-9 x414-6 u. 
Fructifications 2-6 em. high and broad. 
On the ground by roadsides in woods, growing up and con- 
crescent with stems of plants and other parts. Vermont to 
Louisiana and in Missouri. July and August. Rare. 
This species is characterized by its occurrence on the ground 
from which it rises by support of small stems and other objects, 
absence of branches of characteristic form, rather large, sub- 
globose basidia, and the small spores. Lloyd’s figure which I 
have cited does not show the usual aspect of fructifications of 
this species. The form C noted by Gilbert, Wis. Acad. Trans. 
16: 1153. pl. 83. f. 22. 1910, seems to be T. concrescens.
