106 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
An T. macrorrhiza Léveillé, Ann. Sci. Nat. Bot. III. 5: 146. 
1818? See Lloyd, loc. cit., p. 28. 
Illustrations: Lloyd, loc. cit. Not by the figures under this 
name in other works, as Engl. & Prantl, Nat. Pflanzenfam., for 
example. 
Fructifications cespitose, coriaceous, confluent, infundibuli- 
form and deeply split on one side, or little developed on one side 
and prolonged and petaloid on the other; upper 
surface of pilei glabrous, radially plicate, drying 
diamine-brown, the margin paler and more or less 
lobed; stems solid, buffy brown, short, tomen- 
tose, branched above; hymenium radially plicate, 
nearly white, pruinose, often cracked; pileus in 
section 400 » thick, composed of densely and longi- 
tudinally arranged, hyaline hyphae 3 & in diam- 
eter; no cystidia; gloeocystidia 43 y in diameter, 
barely distinguishable from the basidia; spores 
hyaline, even, subglobose, 33-41 u in diameter. 
Fructifications 4-5 cm. high; pilei 1-2 cm. in 
Fig. 7. diameter; stems about 1 em. long, 1-2 mm. in 
S. elegans. diameter 
Gloeocystidia : ^ . 
x 665. In a dense cluster of about 16 fructifications 
springing from an area of 2 square centimeters 
on the ground. Porto Rico to British Guiana. Summer. 
I have not seen the type of Stereum elegans from Dutch Guiana 
nor reference to its existence; a collection from Porto Rico on 
which the preceding description is based has fructifications 
growing on the ground closely together and concrescent where 
in contact; the pilei are plicate on both surfaces and contrast 
so greatly in color that it seems as though fuscous in connection 
with the upper side and whitish flesh-color and pruinose for the 
under side might have been used for the color difference. The 
specimens of this collection are not zonate; infundibuliform 
without any qualification of this character does not seem accu- 
rate; hence it may be that this Porto Rican collection is merely 
near, rather than the true, Stereum elegans. However, solitary 
fruetifications growing on wood, as figured in Engl. & Prantl, 
Pflanzenfam., are certainly a very different species from S. 
elegans, the original description of which is as follows:
