BURT—THELEPHORACEAE OF NORTH AMERICA. XII 215 
Cuba: C. Wright, 515, the S. scytale of Fungi Cubenses but not 
according to the type (in Curtis Herb.). 
70. S. sepium Burt, n. sp. Plate 6, fig. 70. 
Type in Burt Herb. 
Fructification corky, drying rigid, hard, resupinate, becoming 
broadly reflexed, with the upper surface concentrically sulcate, 
somewhat zonate, tomentose, sepia, 
the margin paler and entire; hyme- 
nium even, not shining, between light 
buff and avellaneous; in structure 
600-1500 y thick—up to 3 mm. thick 
in resupinate portion of Mexican 
specimens—, with the intermediate 
layer bordered and connected with 
the tomentum by a denser and 
darker zone and bearing on the op- 
posite side a hymenial layer which 
becomes multizonate; hyphae of 
intermediate layer colored, thick- Fig.4l. S.sepium. Hyme- 
walled, densely and horizontally ar- Eu. E i capis 
ranged, 3-33 u in diameter; cystidia  paraphyses, p. 
inerusted, cylindric, 25-35X7 u, be- 
coming colored where buried in the deeper zones of the hyme- 
nium; paraphyses of bottle-brush or aculeate form, ous and 
conspicuous in the hymenial surface, cylindric, 12-25X 3-5 u; 
spores hyaline, even, 4X23 u. 
Probably resupinate over large areas, for fragments fractured 
on three sides are 6 cm. square; reflexed margin 2-4 cm. long, 
6 cm. wide. 
Under side of rotten logs of frondose species. Pennsylvania 
to Mexico and Colombia. Collected from July to December 
but probably perennial. 
The few collections of S. sepium which have been observed 
have the upper surface of the pileus a little brighter colored than 
that of S. subpileatum and the hymenium more avellaneous, but 
I cannot certainly separate the former from the latter except 
by the very numerous and conspicuous bottle-brush paraphyses 
which are present, in addition to cystidia, in the hymenium of
