. Bulletin of the Department of Agriculture. Agriculture; Agriculture. TIMBEE STOEAGfi W THE EASTERN AND SOUTHERN STATES. 31 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-.
