small, appressed, acicular branches, the larger of which are at 
the apex of the fructification and spread slightly outward in 
fan-shaped manner; stem glabrous, castaneous; hymenium am- 
phigenous, on upper half of the fructification, avellaneo-ciner- 
eous; basidia simple, hyaline, 4-spored; spores pale umbrinous 
under the microscope, angular, 6-8 x 5-6y. 
Fructifications 13-2 cm. high; spread of branches at the top 
2—6 mm.; stem 7-10 mm. long, 1 mm. thick. 
On the ground. Washington. January. 
This species is very distinct by its slender erect habit, cinereous 
color, and only slightly spreading branches. 
Specimens examined: 
Washington: Bingen, Klickitat Co., W. N. Suksdorf, 716, type. 
5. T. angustata Fries, (Nov. Symb. Myc. 92.) Actis R. Soc. 
бе. Upsal. III. 1: 108. 1851. 
Type: in Herb. Fries. 
Fructifieation erect, cinereo-fuscous, pliant, becoming rigid 
and somewhat woody; stem elongated, radicated, rugose, gla- 
brous, compressed, irregularly divided at the upper end into 
unequal, fastigiate, compressed branches, which are clothed on 
the whole outer surface with the hymenium; hymenium amphi- 
genous, subrugose, gray ; basidia simple; spores umbrinous under 
the microscope, obovoid, apiculate at base, flattened on one 
side, echinulate, 14 x 7-94. 
On decaying wood. Central America. 
Substance, color, and hymenium exactly as in T. cornuco- 
pioides, but of the very different form of Clavaria rugosa and 
having highly branched forms; stem 5 em. long; color fuliginous. 
The fructification is fleshy-pliant when fresh, but on drying 
hardens much more than species of Stereum. 
Specimens examined: 
Costa Rica: Oersted (in Herb. Fries), type.

1828. Plate 4. fig. 7a. 
Type: in Herb. Schweinitz. 
Fructifieations gregarious, erect, coriaceous, fusco-cinereous, 
usually drying pallid; pileus infundibuliform, sometimes cleft
