coming from the layer next the substratum; basidia longitudin-

ane eee finally covering areas 7 cm. and more long, 1-2 
em. broad. 
On dead Berberis vulgaris and other frondose limbs. District 
of Columbia and Island of Guam. October and March. 
This species is noteworthy by its gloeocystidia. In the former 
description of this species under Sebacina, based on a gathering 
on Berberis in grounds U. S. Department of Agriculture, Wash- 
ington, in 1902, I noted the presence of some granules on the 
hymenial surface. These granules are numerous in the specimen 
collected in 1819 on the Island of Guam, and by their structure 
in both gatherings require transfer of this species to Hetero- 
chaete. Since the only North American station is on the grounds 
of the United States Department of Agriculture, it seems prob- 
able that H. Sheari is an introduced species in our American 
flora coming from Guam or other distant lands of the Pacific.

DACRYOMYCETACEAE 
Under the name Tremella palmata, Schweinitz described the 
commonest Dacryomyces of New England, southern Canada, 
and northern United States. This species ranges south to Lou- 
isiana and westward to Washington and north to Alaska. I 
have a single gathering on Betula lutea but other specimens 
known to me are on rotting coniferous wood. D. palmatus may 
occur as solitary or gregarious fructifications, with the lower 
portion tapering downward as in the authentic specimen in 
Schweinitz Herbarium and the illustrations by Coker and by 
Lloyd cited on a following page, or it may more usually and 
when better developed be a large, bright orange-yellow cluster 
of probably many fructifications so intimately coalescent as to
