able deterioration within a year. Plate IV, figure 1, shows a small 
pile of shortleaf pine seriously rotted after a period of only 10 
months in a retail yard at Xew Orleans: in fact, the owner of this 
yard suffered so much loss from decay in the less durable grades of 
pine that he has discontinued handling them. 
Fungi are in evidence in lumberyards in the vegetative stage 
(moldlike growths; PL" II, fig. 1, and PL IV, figs. 2 and 3) and in 
the fruiting stage. Almost any species occurring in a given region 
may occasionally be introduced into storage yards, but the great 
majority of the speci- 
mens found fruiting fall 
within a comparatively 
few species. 
One of the common 
forms, Polystictus versi- 
color (L.) Fr., is shown 
in Plate IV, figures 4, 
5, and 6, growing both 
from the ends of stored 
hardwood ' lumber and 
from built-up plank 
foundations (PL III. 
fig. 3). This organism 
is profusely distributed 
throughout t h e entire 
United States and is 
more destructive to 
hardwood timber than 
any other fungus. 
Other members of this 
genus, such as Poly- 
stictus hirsutus ( Schrad. ) 
Fr. (PL IV, figs. 7 and 
8), P. pargamenus Fr. 
(PL V, figs. 1 and 2), 
and P. abietinus Fr. (PL V, figs. 3 and 4) are likely to be found in 
most lumberyards throughout the United States, occasionally fruit- 
ing on stored lumber, but more often causing sap rots of tramway 
timbers, foundations, and ties. The last species grows on coniferous 
timber almost exclusively ; the other two on hardwood timber. 
Among other members of the true pore fungi may be mentioned 
Polyporus adustus (Willd.) Fr. (PL V, figs. 5 and 6), which is usu- 
ally thin, tough, and leathery, creamy above and smoky below; 
P. sanguineus (L.) Fr. (PL VI, fig. 4), of a bright red through- 
P94F 
Fig. 32. — A retail shed in Alabama in which the lum- 
ber projects beyond the eaves, thus catching the drip 
from rains. This condition favors decay when the 
water runs back along the boards into the piles.
