BURT—THELEPHORACEAE OF NORTH AMERICA. XII 203 
Fructifications 4-8 X 1-2 cm., margin reflexed 1 mm. 
On bark of fibrous structure of an unrecorded species. Cuba 
and Jamaica. Rare. 
S. ferreum may be recognized by its resupinate, drab fructifi- 
cations, rarely having a narrowly pileate margin, and by the 
thick hymenial layer containing innumerable small colored 
cystidia which at the surface of the hymenium have the colorless 
incrustation roughened. So few spores were observed that it 
may be they were foreign spores. S. ferreum is at least closely 
related to S. areolatum, a European species occurring on Taxus, 
and I have been inclined to regard it as not specifically distinct 
from the latter, but we do not know yet that S. ferreum occurs 
on Taxus or a related genus; if not a strictly tropical species but 
a synonym of S. areolatum, the lack of a northern range in 
eastern United States is at variance with species common to 
Europe and North America.
