brown or brownish fawn- colored ,‚ variegated with narrow 
darker glabrous zones, margin whitish; pores minute, obtuse, 
short, subrotund, whitish or pallid; flesh pallid. 
Dead branches. 
This has the colors of P. scutellatus, but the thin plane 
pileus and short pores are so unlike that species that I am 
compelled to regard it as distinet. 
Polyporus (Resupinati) subiculosus Pk. Subieulum 
widely effused, dense, but soft and downy-tomentose, tawny- 
einnamon; pores forming patches upon the subiculum, short, 
unequal, sometimes slightly labyrinthiform, einereo-ferrugi- 
nous, ferruginous-brown when bruised, the dissepiments 
when young whitish and pruinose-villose. 
Creeping over mosses, decaying wood, and even stones, 
in sheltered places. Oet. 
The patches are several inches in extent. The pores 
have a paler hue than the subiculum, but they become darker 
when bruised. : 
Polyporus (Resupinati) semitinetus Pk. Subiculum 
thin, soft, cottony, separable from the matrix, whitish, more 
or less tinged with lilac, sometimes forming branching cree- 
ping threads; pores very short, unequal, whitish or pale 
cream-color, the dissepiments at first obtuse, then thinner, 
toothed on the edge. 
Under surface of maple chips. Sept. . 
This is a soft, delicate species, with merulioid pores, 
similar to those of P, violaceus, The lilac stains appear on 
the subiculum only. 
Polyporus Y Resupinati) induratus Pk. Eiffused, 
hard, determinate, 1“—2* thiek, inseparable from the matrix, 
almost wholly composed of minute subrotund vesicular pores, 
yellowish or pale-ochre, the surface slightly pruinose 
tinged with flesh-color; the yellowish mycelium or subieulum

Decaying wood. Ä 
. "This npeciD is remarkable for the peculiar character 
of the pores which form little cells or cavities instead of 
tubes, so that in whatever direction the mass is cut or 
broken, the section appears equally porous. Perhaps this 
character will necessitate the formation of a new genus. 
Hydnum sulphurellum Pk. Subiculum thin, effused, 
definite, sometimes rimose, pale sulphur-yellow ; a Bee 
tered, conical, subobtuse, sometimes compound, colo te 
2% subiculum; spores oblong, slightly curved, .0002°—.
