the fructification sagged by its own weight into cup-shaped 
form in the space between the several supports. It was such a 
form which led Schweinitz to publish the original collection as 
a Peziza. When incrusting only two stems the fructification 
sagged between the supports in the form of a whitish pellucid 
membrane. By its dependence for support of its mass upon 
herbaceous stems and by absence of projecting self-supporting 
lobes, Tremella concrescens is distinguishable at sight from T. 
reticulata, which is also white and grows on the ground but 
stands up a self-supporting, coralloid mass with many short 
cylindric branches. T. reticulata has been frequently collected 
in the northern United States from Vermont westward to Min- 
nesota but with southern limit the North Carolina station given 
by Coker. 
Tremella fuciformis Berk. is the third species of the group. 
This is a tropical species ranging from Brazil through the West 
Indies into the southern United States as far north as North 
Carolina. It has been collected but few times and has always 
been found growing on wood. "There has been a tendency to 
confuse both T. reticulata and Dacryomyces pellucidus, the syn- 
onym of T. concrescens, with T. fuciformis but the growth from 
the ground, not wood, seems a reliable means of distinction, 
although there are additional features of distinguishing T. 
fuciformis when it has to be determined in the herbarium from 
dried specimens not accompanied by notes as to substratum. 
T. fuciformis dries with the upper portions white and the basal 
portion in the region in and near the wood ochraceous tawny; 
it agrees with T. reticulata in being self-supporting and branched, 
but in dried condition main trunk, main branches, and final 
branches are not at all cylindrie but flattened into leaf-like 
form with branches at the margins of the main trunk and main 
branches and all in à common plane although more or less crisped 
by the great number of ultimate branches. There are differ- 
ences between these three species in microscopic characters 
which are given in the following more complete descriptions 
with synonymy, etc.
