88 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
protruding up to 12 u, are sometimes present; spores hyaline, 
even, 8-10X 3-41 y. 
Fructifications 2-10 cm. high, 2-15 em. in diameter; stem, 
when present, 5 mm. — 2 cm. long, 2-5 mm. thick, often sessile. 
On decaying wood of frondose species. Florida, Louisiana, 
and West Indies to Bolivia. June to April, probably throughout 
the year. Common. 
S. caperatum is the largest infundibuliform Stereum of the 
Gulf states and the West Indies. Its large size, upper surface 
with elevated, radial ridges and usually heavy tomentum of 
coarse fibers, occurrence on wood to which it is attached by a 
villose or tomentose disk, constitute a group of characters by 
which the S. caperatum is readily recognized. Lloyd has pub- 
lished in his account of this species that it has true metuloids 
(inerusted cystidia) projecting 20-30 y, but I have found none 
whatever in either the type or in other collections referable to 
this species. 
Thelephora lamellata Berk. & Curtis, a species of Stereum related 
to S. caperatum and of rather similar aspect, occurring on islands 
of the Pacifie, shows in the type specimen from Fiji Islands 
conical incrusted cystidia 6-12 » in diameter, protruding 12-25 y, 
and subglobose spores 3-35 X34. Since Lloyd cited S. caperatum 
as occurring in Samoa, the Philippines, and Australia, it is 
possible that his observations on incrusted cystidia of S. capera- 
tum were based on specimens from the Pacific region really 
referable to Stereum lamellatum rather than on the true S. 
caperatum from the American continent. In Hedwigia 53:75, 
1913, Bresadola gives T. lamellata as a synonym of Cladoderris 
infundibuliformis (Kl.) Fries. I have seen no American speci- 
mens referable to S. lamellatum.
