92 THIRTY-EIGHTH REPORT ON THE STATE MUSEUM. 
phoid branching strings of mycelium or forming a somewhat reticulate 
fimbriate membrane ; pores minute, subrotund, equal, whitish inclining 
to cream color. 
Under side of prostrate trunks of maple, forming extensive patches — 
on the wood and bark. Osceola. Aug. 
By its rhizomorphoid mycelium this species is related to P. Vaillantit, 
but the pores are smaller and not collected in heaps as in that species. 
By reason of its tenacious substance it is readily separable even from an 
irregular matrix. 
Polyporus (Physisporus) ornatus, 1. sp. 
Effused, 1 to 2 lines thick, somewhat tenacious, adnate or insep- 
arable from the matrix, white, the surface slightly undulate or uneven, 
the margin definite, studded with drops of moisture when fresh, spotted 
with dot-like depressions when dry ; pores subrotund, minute, unequal, 
often oblique. 
Decaying prostrate trunks of deciduous trees. Osceola. Aug. 
This species is at once distinguished by its adnate subiculum and its 
peculiarly spotted margin. The spots are watery white in the fresh state 
and each one is covered by a drop of moisture. In the dried plant the 
place previously occupied by the drop of moisture becomes a small 
depression in the subiculum. 
Polyporus (Physisporus) odorus, 2. sp. 
Effused, 2 to 3 lines thick, even, firm but brittle, moist, separable 
from the matrix, white, sometimes stained with reddish-yellow on 
the abrupt, rather thick, slightly fimbriate margin ; pores very minute, 
rather long, equal, entire, white, arising from a thin but distinct subic- 
ulum ; odor strong, disagreeable. 
Under surface of decorticated prostrate trunks of spruce. Osceola. 
Au 
it forms patches several inches broad and sometimes more than a foot 
long. It is distinguished from P. vulgaris by being separable from the 
matrix, moist, having longer pores and a strong odor. From the next 
following species it may be known by its smaller pores, more brittle 
texture and its different odor. 
Polyporus (Physisporus) subacidus, 2. sp. 
Effused, separable from the matrix, tenacious, flexible, uneven, deter- 
minate, the margin downy, narrow, pure white ; pores small, subrotund, 
1 to 3 lines long, often oblique. whitish inclining to dingy-yellowish 
pale tan color or dull cream color, the dissepiments thin, more or less 
dentate ; odor strong, subacid. 
Prostrate trunks and decaying wood of various trees, hemlock, Sprung; 
birch, etc. Osceola. July. 
This species is not rare, but it has probably been confused with its 
allies. It forms extensive patches, sometimes several feet in length. It 
adheres somewhat closely to the matrix, but its texture is so tough that 
it is generally easy to strip it from its supporting substance. It is ap- 
parently closely related to P. medulla-panis, but the description of that
