- Fomes ungulatus Sacc. Sylloge, 6: 167. 1888. 
A large and widespread species growing abundantly on conif- 
erous trees, such as the hemlock and pine, and found more rarely 
upon deciduous trees standing near its usual hosts. Beech, elm, 
maple and birch are known to have been attacked by it in Ameri- 
can and European forests where conifers abound. Fresh speci- 
mens collected on fir trees in Sweden correspond in all respects 
with Schaeffer's B. wngulatus, so 1 do not hesitate to use his name. 
Collections showing the range of this plant are as follows : Saxony 
(Krieger 13), Sweden (Romell 116, Murrill), Siberia (de Thiimen 
1906), France (Roumeguére 2205), Bohemia (de Thiimen 814), 
Hungary (Linhart 250, 446), Canada (Macoun), New Hampshire 
(Minns), New York (Atkinson, Underwood, Murrill), Colorado 
(Crandall, Cockerell), West Virginia (Nuttall), Michigan (Wood), 
Maine (Ricker), Virginia (Murrill).

This species was described from plants collected by Anderson 
in Montana during the summer of 1889. Its only host thus far 
reported is Shepherdia argentea Nutt., on the living trunks and 
branches of which it is very abundant in the Teton Valley.
