descriptions given by Fries. Our specimens correspond both in 
structure and color very closely to those figured by Bulliard. 
There seems to me to have been no adequate reason why Fries 
should not have retained the name mesenteriformis for the 
forms to which he gave the name frondosa. Our specimens are 
strikingly characterized by the name mesenteriformis. 
His figure of Tr. deliquescens is a fairly good picture of our 
Wisconsin specimens of Dacrymyces deliquescens and the same 
may be said of his figure of Tr. glandulosa as representing our 
Exidia glandulosa (Bulliard) Fr. 
Bulliard’s Tr. cerebrina (Tr. albida, Huds.) if not so tall 
would fairly well represent the forms found here which I have 
identified as Exidia albida Bref. The figure of Tr. auricula 
Judae is also very good for our specimens. His figure of Tr. 
mesenteriformis var. violacea, (Tr. foliacea-violacea Fr.) looks 
much more like smaller, denser forms which I have included 
with Tr. frondosa Fr., than like the forms I have included un¬ 
der Tr. foliacea var. purpurascens which are still much more 
compact and have thicker folds. They more nearly resemble 
light colored forms which I have included under Tr. frondosa, 
(though doubtless the same as those identified by Fries as Tr. 
lutescens Pers.). 
Here again Bulliard’s conception of the specific delimination 
of the main species which he calls Tr. mesenterica seems much 
better than that of Fries. 
In the Systerna Mycologicum (30) of the elder Fries, we find 
the classification which has been used as the basis for all later 
work. We find the Tremellas for the first time brought to¬ 
gether in these genera; Tremella, Exidia, Femsjonia, Hirneola, 
Naematelia, Guepinia and Dacrymyces. 
Later authors have largely accepted these genera as Fries de¬ 
limited them. It is to be noted, however, that even in this later 
work the Caloceras, are not included among the Tremellineae. 
The American students of the fungi have done little with the 
Tremellineae , but the commoner speoies have been reported in 
most of the local floras which deal with fungi. It is most un¬ 
fortunate that- in most cases, neither specimens nor figures of
