It is not a Poria, because it is not truly resupinate; when 
fully grown it has a distinct reflexed pileus. The hymenium 
is at first wholly porose and the species might be called Poly- 
stictus tulipiferae. The early stage is liable to be confused with 
Merulius corium Fr. I have seen it labeled Polyporus niphodes 
B. & Br., which may be true for all I know, but Schweinitz’s 
name must take precedence. The favorite habitat of the species 
is on the timber of the Liriodendron, but it abounds on branches 
of Hickory and it may be found on Acer, Fagus, and other 
trees. I have never seen it on Pine or any other Evergreen. 
PRELIMINARY NOTE ON TWO NEW GENERA OF 
BASIDIOMYCETES. 
GEO. F. ATKINSON. 
I. TREMELLODENDRON, A NEW GENUS OF TREMELLINEAE. 
In studying the structure of Thelephora Candida (Schw.) 
Fr., and T. pallida Schw., a little more than a year ago, I was 
surprised to find that they are not members of the Thelephoraceae, 
but belong in the Tremellineae, on account of the globose, cruci- 
ately divided basidia. They differ quite markedly from any of 
the described genera of the Tremellineae, but approach nearest 
(especially T. Candida), perhaps, to Sebacina Tul. In Sebacina 
Tub, however, the plants are effuse and incrusting, only rising 
from the substratum in an irregular manner, or when encrusting 
erect objects, as grasses, herbs, sticks, etc. T. Candida (Schw.), 
Fr., and T. pallida Schw. normally grow erect from the sub¬ 
stratum and have a characteristic, more or less dendroid branch¬ 
ing. They represent the type of a new genus for which I pro¬ 
pose the name Tremellodendron Atkinson n. g., with Tremello- 
dendron candidum ( Merisma Candida Schw.), and Tremelloden¬ 
dron schweinitzii ( Thelephora schweinitzii Pk., T. pallida Schw., 
not T. pallida Pers.) as representative species (at least in part), 
for it appears that there are true Thelephorae which are nearly 
or quite impossible to separate from T. pallida Schw., without an 
examination of the hymenium. 
II. EOCRONARTIUM, A NEW GENUS OF AURICULARIACEAE. 
This very interesting plant might very easily be mistaken for 
Typhula muscicola if the spores and basidia were not carefully 
examined. The plant was collected on living moss, July 8, 1902,
