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 New 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 vegetatii^e 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 the 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. alietinus 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 menlbers 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- 



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.
