130 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
is in F. applanatus Pers. ex Wallr. That species always grows 
on old logs and stumps and has a rusty brown context. 
Bresadola and Murrill regard F. populinus Schum. ex Cooke, 
to be the same plant as this species. This may be the case 
but the figure of F. connatus in Fries’ 'Icones' (f. 185) represents 
our plant much better than the figure of F. populinus in ‘Flora 
Danica’ (pl. 1791). Most of the specimens distributed in 
exsiccati in both this country and Europe are under the former 
name and that one is here given preference. А study of the 
types of both species should show whether they are the same 
or not, but from the evidence at hand our plants must be 
referred to F. connatus.

Plants perennial, sessile; pileus plane to convex, rarely ungu- 
late, dimidiate, 4-15 x 6-20 x 3-10 cm., woody and rigid, gray- 
ish to black, partly or entirely covered with a reddish gluten 
that forms a crust over the surface, glabrous, sometimes con- 
centrically suleate, margin thin or thick, often obtuse; context 
pallid or wood-colored, corky to woody, 0.5-2 em. thick; tubes 
3-5 mm. long, distinctly or indistinctly stratified, the mouths 
white to umber, cireular, averaging 3-5 to a mm., the walls 
thick and entire. 
On dead wood, usually of coniferous trees. 
Distinguished from closely related species by the resinous, 
somewhat sticky, reddish crust found on the pileus. The 
plant is common wherever coniferous woods are found. Hard 
(Mushrooms f. 348) gives а photograph of it but does not state 
that he ever collected it in Ohio.

Plants annual or perennial, sessile, sometimes imbricate; 
pileus dimidiate, 4-10 x 6-15 x 0.6-2 em., согЕу when fresh, 
rigid and woody when dry, light colored, always with reddish 
or reddish brown stains, or altogether reddish, encrusted with 
a thin hard crust, minutely velvety to glabrous, more or less 
zonate, margin thin or thick, acute; context floccose-punky
