116 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructifications cespitose, stipitate, coriaceous, erect, white, 
now between light buff and cartridge-buff throughout; stem 
cylindric, branched above, the branches either slender, cylindric, 
sterile bodies, or flattened, membranous pilei 1-2 mm. broad, 
1-13 em. long; hymenium on the lower side, even; a few de- 
tached spores hyaline, even, 34X3 u, none found on basidia. 
Fructifications about 3 cm. high; stems 3 mm. in diam.; 
pileate branches 1-15 cm. long, 1-2 mm. broad. 
On roots of trees. Brazil. 
Berkeley described S. proliferum as somewhat creeping and 
having the branches with tips attached again to the matrix by 
means of large, orbicular, radiated and laciniated disks. These 
characters should render this species easy for the collector to 
recognize, but the herbarium specimen which I studied did not 
show the above feature noticeably; it had somewhat the aspect 
of S. Hartmanni but without the pectinate margins of the latter. 
The hymenium of the specimen studied is in poor condition and 
the spore characters, as given above, are uncertain. I studied 
for N. Y. Bot. Gard. Herb., No. 508, a fungus collected at 
Church Cove, Bermuda, which has the general aspect of S. 
proliferum but with spores hyaline, even, 13-16 6-7 y, and is 
probably a distinct species. Still it is well to keep S. proliferum 
in mind in connection with species of the West Indies. 
Specimens examined: 
Brazil: Rio Negro, Spruce, 17, type (in Curtis Herb.). 
29. S. caespitosum Burt, n. sp. Plate 4, fig. 25. 
Type: in Burt Herb. 
Fructifications coriaceous, thin, cespitose, effuso-reflexed, 
with the resupinate portion small and bearing a cluster of broader 
and longer, imbricate, pileate lobes which are somewhat fur- 
furaceous or with minute tomentum on the upper side, glabrate 
towards the margin, drying tawny and zonate with ochraceous, 
tawny zones, the margin entire; hymenium even, whitish to 
light buff; in structure 500-700 uy thick, with the intermediate 
layer bordered above by a narrow, slightly colored zone and 
composed of densely longitudinally arranged, hyaline, thick- 
walled hyphae 33 „u in diameter; hymenial layer up to 120 y 
thick, containing numerous slender, flexuous gloeocystidia
