tubes ; tubes unevenly stratified, 0.5-0.75 cm. long each season, 
I—2 toamm., ochraceous within during the first season, afterwards 
latericeous, mouths circular, ochraceous, edges obtuse, rather thin : 
spores ellipsoidal, smooth, thick-walled, ferruginous, 7-8 x 9 
Collected by Earle in August, 1900, on a standing trunk of 
Juniperus in the El Capitan Mountains, New Mexico, at an attitude 
of 7,000 ft. It is closely related to P. juniperinus (Schrenk), but 
it is much more rimose, has larger pores and lacks the annual 
projecting margins of the older tube-layers so characteristic of 
that species.

Boletus salicinus Pers. and Boletus conchatus Pers. were differ- 
ent forms of the same plant. Most of the old willow stumps in 
Sweden are covered with it. On the sides of the stumps it is B. 
salicinus and farther up, where the pileus is reflexed, it is B. con- 
chatus. This fungus is quite common in Europe and America on 
a variety of hosts. The following list includes only a few of the 
collections examined: Sydow, Myc. Mar. no. 3423 ; Ellis, N. A. 
Fungi no. 918; Romell, Fungi Suecici no. 12; England (Plow-

Indiana (Underwood), Canada (Macoun), Ohio (Lloyd, Morgan), 
Pennsylvania (Rau). 
12. Pyropolyporus Haematoxyli sp. nov. 
A smooth applanate plant of considerable size with aguante 
tubes and honey-yellow context. Pileus woody, dimidiate, S e,

shallowly concentrically sulcate, marked with ae stig
