Found usually on dead poplar, and varies greatly in form but 
is usually distinguishable by its bright orange color, and dries 
down into irregular patches which become more transparent and 
watery in appearance. Specimens vary in size from 1 cm to 4 
cm across and 1-2 cm in height. 
Common, Madison and vicinity. 
0. Tremella foliacea Pers. Fig. 11. 
Tremella succina Pers. (Myc. Eur. I. p. ,1*01.) 
Tremella ferniginea (Engl. Bot. taf. 1452.) 
Tremella mesenieriformis Bull. (Champ, tab. 406 A.) 
Tremella violascens Alb. et Schw. (Sonsp. Fung. p. 305.) 
Tufted and much lobed and waved, segments thin, springing 
from a plicate base; color variable, diaphanous, pinkish cinna¬ 
mon, rarely deep hrown or even violet; spores reniform 10-12 
by 5-6/x; conidi a like spores. Substance soft gelatinous, at 
first rounded but gradually becoming very irregular. 
It is to be noted that this differs from the true tremellas as 
arranged by Brefeld in that the spores are different in shape 
and the conidia much larger. This species with Tr. saccharina 
is so variable in color and in appearance at various times that 
there is no doubt in my mind that these two forms with Tre¬ 
mella frondosa are often mistaken for one another. 
Specimens are found on many large trees reaching in di¬ 
ameter from 2-10 cm and from 2-5 cm in height. The form is 
described as being thin hut that is not always the case as some 
specimens have the lobes quite thickened. Many of the speci¬ 
mens approach more nearly the variety violescens of Alb. et 
Schw. in being smaller, thicker and of a general purplish red 
and even violet color. 
This form is more often found on oak, alder and birch. 
Common. I do not think that the term foliacea can be re¬ 
garded as descriptive since a specimen is rarely found which 
can be said to be foliaceous in appearance.
