Pàgina 17 - ... falling apart as soon as cut across. This peculiar action of Lenzites sepiaria, the writer believes, is due simply to the structure of the annual ring, which in some species of trees exhibits distinct differentiation between the early, porous portion and the later, more compact portion. Boiling tests made by the writer (1906) showed conclusively that the lignin of the early wood is more easily dissolved than is that of the late wood of the same annual ring, where the two parts are at all distinct....
Pàgina 10 - They rarely project more than 2 inches from the and are commonly long, narrow, shelf-like formations, extending horizontally from the surface of the wood. They are frequently compound or are clustered very closely together, and are especially numerous on the ends of affected timbers (PI. I, fig. 1). When they are on the sides of the timber they are almost certain to be situated in season cracks (PI. Ill, fig. 3). Sometimes, on a very badly rotted log, many sporophores situated in a single season...

Pàgina 9 - ... the writer upon the heartwood of Tsuga canadensis (\\ No. 2085) and Larix laricina, and it often attacks the outer layers of the heartwood in many other species. Whether it is able to rot the resinous heartwood of the southern pines seems questionable. The writer has seen no instance where this had taken place, except in the outer layers of heartwood which were not so completely filled with resin as the inner ones.
Pàgina 16 - ... birch tree, making slits in the branches in which spores of Polystictus versicolor were placed, but the results were inconclusive. Price (38) also was unsuccessful in his inoculation tests with Polyporus squamosus. Spaulding (44) says in connection with his tests of Lenzites sepiaria on longleaf pine "absolutely no results could be detected from six inoculations made in the living trees," and concludes the species is a strict saprophyte.
