Gilbert—T.remellce of Wisconsin. 1T41 
the forms collected by Schweinitz (34) are available for study. 
It is to be-remembered that the group was imperfectly underv 
stood at that time, and it seems doubtful whether the Schwein- 
itzian species will be identifiable in many cases. 
Tulasne, (53) studied further the internal structure of the- 
carpophore and the hymenium, and it is to him that We are in¬ 
debted for the earliest data as to the germination of the spores. 
His figures have been widely copied. He figures Tr. mesem 
terica, Ex. spiculosa, Tr. violacea, and D. deliquescens in his 
first papers (53), and in his second series (62) he figures fur¬ 
ther Guepinia peziza and gives three sketches of Tr. cerasi and 
one of Pilacre. 
Paulet et Leveille (54a) give a few colored figures, but they 
are difficult to identify. Their figure of Tremellodon may pos¬ 
sibly be our species gelatinosum. Their Tr. mesenterica, Mur¬ 
ray. PI. Ill, fig. 5 can hardly be a tremella. Their Tr. hyd~ 
noides Jacquin PL III, fig. 6-7 is probably our Tremellodon 
gelatinosum. Their Tr. undulata PL CLXXXYI, fig. 3, they 
identify with Tr. mesenterica Pers. They also figure Tr. sar- 
coides Pr. Pl. CLXXXVIL fig. 5. 
Gillet (68) gives excellent colored figures of Tr. mesenterica 
Pers. and Tr. lutescens Petz. They represent, however, much 
larger forms than any I have found in Wisconsin. 
Winter (90) reproduces for the most part Tulasne’s figures 
for the types of the genera. A good proportion of the species 
reported from America are described in Winter’s flora. 
Brefeld, (91) spent years of careful study on the germina¬ 
tion of the spores and the formation of the mycellia and conidia 
of the group, and his work has since been authoritative on these 
points. Brefeld makes the Tremellineae of Pries and De Bary 
the basis of his group of Protobasidiomycetes, but includes 
Dacrymyces with the Autobasidiomycetes. Still in my opinion 
the similarity of their fruiting bodies in form and consistency 
and their evident relationship to the other members of the group 
are sufficient justification for keeping Dacrymyces with the 
Tremellineae. 
Bresadola, (110) gives a colored figure of Tr. foliacea Pers.
