TIMBER STORAGE IN THE EASTERN" AND SOUTHERN STATES.

laid on flat 2 by 6*s resting on ashes was very quickly rotted out by 
this same fungus (PL IX, figs. 3 and 4), likewise offers circum- 
stantial evidence. 
The remaining fungus which needs consideration is Penlophora 
gig ant ea (Fr.) Mass. (PL X, figs. 5 and 6). This is a white to 
pale creamy moldlike growth when immature. TVLien mature it 
forms a waxy incrustation on the surface of the timber, closely ad- 
herent when fresh, but when dry tending to become hard and horny 
and to curl up at the free edges. This organism is widely distrib- 
uted, mainly on pine timber, throughout the southern pine belt, and 
also occurs on conifers in the Eocky Mountain region. In the South 
it is frequently found in the woods, whence it readily passes to 
stored lumber. Many lumberyards have been abundantly infected 
with it ever since they 
started in business; so 
long, in fact, that to 
sever the attachment 
would be like losing 
an old acquaintance. 
From the southern 
yards it has been in- 
troduced northward 
and is very conspicu- 
ous at certain points 
along the North At- 
lantic coast (PL III, 
fig. 7). The timber 
.reaches these points 
mainly by boat. Close 
storage of the green or 
partially dried stock 
in the hold of a vessel 
during an ocean voy- 
age of perhaps several 
weeks usually permits 
a vigorous development of the fungus. As a result of this, infections 
are so abundant in some of the North Atlantic yards that one would 
have difficulty in finding any clean material whatever. 
It is fortunate that the organism does not approach in clestructive- 
ness such forms as have been previously described, else many lumber- 
yards would be doomed immediately. It is a wood-destroying fun- 
gus, however, which limits its action to the sapwood. Although the 
deterioration is comparatively slow, it does weaken the timber to a 
considerable extent and should be guarded against along with the 
more dangerous fungi.
