This plant has occurred several successive seasons in July 

 and August, on the ground upon a dry hilltop in open woods, 

 Glen Ellyn. It forms sessile tuberculous masses 7.5 to 12 cm. in 

 diameter and 2.5 to 5 cm. in height, wholly composed of stout 

 gelatinous processes, branched two or three times, the lobes or 

 processas compressed and somewhat hollow; spores white, ovoid, 

 inequilateral, 6 to 9 x 4 to 6 p. 



Tremella foliacea Pers. 



Cinnamon-flesh-color, cespitose, even, undulated, plicate at 

 the base; surface finely granulated, the granulations pale. 



Clusters 1 to 2.5 cm. broad, soft and watery, leaving little 

 residue when dried. 



On dead stumps, Glen Ellyn. September to November. 



Tremella mycetophila Peck, X. Y. Mus. Rep. 28; 53, has been 

 referred by Prof. Burt to the genus Exobasidium. See Bull. 

 Torr. Bot/Club 28; 285. 



The species has been found several times at Glen Ellyn, 

 parasitic on decaying stems and pilei of Collybia dryophila.
