to be most like those described by Farlow. Common in tbe 
woods of Madison and vicinity. 
Form c. fig. 22 forms an urn like mass on old stems of 
bracken. It bas a gelatinous-cartilaginous consistency with 
basidia deeply imbedded in the substance and of the typical 
tremella type. The fungus was attached to the stipe of the 
fern at the base but was free at the top forming a distinct cup. 
Its color was a pure white much clearer than that of form a. 
It was unbranched and entire except for a few large wave like 
folds. The whole had a diameter of about 3 cm and a height 
of about 5 cm. Spores were white, oblong. Found in dense 
woods, Blair, Wis., August, 1906. 
Form d, fig. 18. Pure white, club shaped, much thickened 
at the top and plicate folded, partly hollow, stipe slightly yel¬ 
lowish in color, 2 cm by 4 cm. Found on ground in dense 
woods. Hymenial layer over entire surface and basidia of the 
ordinary tremella type. I have been unable to secure any 
spores of this form. It was thought at first to be a young stage 
of Form a, but the fact that the basidia were found over its en¬ 
tire surface seems to indicate that the plant had reached its ma¬ 
ture form. A single specimen from Madison. 
Farlow reports the interesting fact that Corticium tremel- 
linum B. and Bav. and Cort. tremelliituin var. reticulatum are 
not corticiums but Tremellas and that the latter is a distinct 
species Tr. reticulata (Berk) Farl. Farlow believes that At¬ 
kinson’s specimens belong also with Tr. reticulata and that Tr. 
fuciformis from South America and the West Indies, is a dis¬ 
tinct species. Specimens in our collections seem to agree well 
with both Atkinson’s and Moller’s figures. The fungus is cer¬ 
tainly quite variable in form. It is to be noted that our forms 
are found on the ground as well as those of Atkinson. The 
South American forms are reported on rotten wood and Far- 
low’s specimens were found growing over the ground and fallen 
branches. The spreading habit referred to by Farlow and men¬ 
tioned in the note appended to the description by Berkeley is 
not characteristic of our Wisconsin forms which are even when
