Linnaeus in bis Species Plantarum (8) names seven species 
for the group of which only one is now included in it. 
Schaeffer (14) does not mention the group as such, hut in his 
group Elvella. he describes a form seemingly a tremella, pos¬ 
sibly Tr. sarcoides. This form and a.few others described by 
him seem to be tremellas, but their specific identity is not to be 
determined with certainty. 
Persoon (23) iii his Synopsis Fungorum may be said to be 
the first to make a fairly practicable classification of the group. 
He includes the Tremellineae in his second class of Fungi 
(Gymnocarpii ) and the fifth order, the Hymenothecii which he 
divides into six suborders the last of wdiich the Helv'elloidei, in¬ 
clude Spathularia, Leotia, Helvetia, Morchella , Tremella, 
Peziza, Ascobohis, Ilelotium, Stilbum and Aegemta. 
Persoon is the first to exclude all aquatic forms and in this he 
is far in advance of his contemporaries, who all included Nostoc 
forms with the Tremellas , but on the other hand, his inclusion 
of the group with Lie ascomycetous genera noted shows how 
little he had on which to base a natural classification. In his 
Mycologia Eurcpaea (33a), he rearranges and modifies his 
earlier grouping. The Tremellas are here put in the second or¬ 
der and co-equal with My coderma , Thelephora and Clavaria. 
He separates the Auricularias from the Tremellas and puts 
them into a genus by themselves. The descriptions are still 
very meager, but he gives more references to the literature of 
the group. Ho figures are given. 
Albertini et Schweinitz (28), base their classification upon the 
earlier work of Persoon, and describe additional varieties of cer¬ 
tain of Persoon’s species. The descriptions are, however, frag¬ 
mentary and their figure of a Tremella , (Tr. saligna nobis Tab. 
IX. f. 7) is. of no value for identification. 
Bulliard (30), makes the Glavarias and Tremellas the second 
of his four orders of Fungi, but errs in including some aquatic 
forms with them. 
Bulliard’s colored figures of many of the forms are most ex¬ 
cellent. Tremella mesenteriformis (Tr. frondosa Fr.) is in¬ 
finitely more easily identified from his figures than from the
