Tab. 209, Fig. I, which, however, is very much like forms I 
have included with Tr. frondosa and very much more leaf like 
and larger than the forms of foliacea found by me. 
Moller, (118) accepts Brefeld’s classification and adds to the 
group, as a result of his work on tropical forms, a large number 
of new genera. His figures of Tr. fuciformis well represent 
our specimens of this species. His figure of Tr. undulata, how¬ 
ever, is very much like loose, open forms of what I have called 
Tr. frondosa. 
Arthur (136) has proposed to use the name Tremella for the 
Gymncsporangia, but it remains to be seen whether a name so 
well established in its present usage can be thus transferred. 
Atkinson’s (142) figure of Tr. frondosa is a good representa¬ 
tion of forms which I have found here. He describes the speci¬ 
mens as pinkish yellow in color, but our forms are purplish to 
deep wine color. Our yellowish forms are much more compact, 
relatively taller, and much smaller. Atkinson’s figure of Tr. 
fuciformis is also a fair representation of the coarser, bulkier, 
forms found here which I shall follow Farlow in identifying as 
Tr. reticulata (Berk) Farlow. Atkinson (150) describes the 
basidia of Thelephora Schweinitzii as of the Tremella type and 
proposes to make for it the new genus Tremellodendron to in¬ 
clude also Thelephora pallida Bres. 
Thelephora Schweinitzii is a very common fungus in this 
region. It frequently shows a yellowish incrusting hvmenial 
layer about the base with the basidia of a Sebacina or Exidiop- 
sis. Whether this hvmenium does not belong to a parasitic 
Exidiopsis form is a question which in my opinion needs fur¬ 
ther investigation. For the present I have not included this 
form with the Tremellineae. In this connection Ceraoea verni- 
cosa Cragin, must also be further studied. This is reported as 
forming incrusting masses on immature specimens of Poly- 
porus. 
Massee (160), makes a curious statement that he has not 
been able to find a true septum in the sense of a plate separating 
the substance of the apex of the basidium in Tremella, but con¬ 
siders that the cross marking present at the apex of the basidium
