112 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
S. fissum may yet be found as far north as the West Indies and 
Central America. The species is noteworthy by its occurrence 
on dead twigs in scattered, solitary, azonate fructifications which 
are often deeply split into segments, and by absence of cystidia 
and gloeocystidia. 
Specimens examined:

anum.

Stereums, 35. 1913. Plate 3, fig. 20. 
Type: in Kew Herb. and Curtis Herb. 
Pileus small, flabelliform or spatulate, drying pinkish buff, 
longitudinally fibrillose, bibulous, the margin entire, narrowed 
behind into a short stem-like base; in structure up to 600 y 
thick, composed of thin-walled, hyaline hyphae 23-3 y in diam- 
eter, interwoven in the subhymenium; hymenium even, dry- 
ing of same color as upper surface of pileus; no conducting 
organs, gloeocystidia, nor cystidia; spores hyaline, even, 4-5X 
3-33 y. 
Pileus 3-6 mm. wide, 5-7 mm. long. 
On a bank among moss. West Indies. February and March. 
S. cyphelloides differs from most Stereums in not having a hard 
compact structure, as in S. rameale, for example; it is of soft and 
bibulous texture but rather too thick for a Cyphella. The stem- 
like base is flattened in the same plane with the pileus and has the 
hymenium continued along its whole length, hence it is merely a 
narrowed portion of the pileus.
