In It is shown one of the hollow teleutospore-cushions; five cushion-scars; in the second-year ring are two shaded zones of wood, chiefly composed of ixxronchyma. (x 25.) (After Woernle.) The sporogenous cushions of G. sabinac are formed in quite a different manner from those of G. davariaeformc. Beneath each cushion the bast increases very rapidly and forms an out- growth, which is still further enlarged by the addition to its apex of six or seven rows of radially arranged cells, rounder and smaller than the bast-cells of the cushion. The mycelium penetrates between these outer cells, and forms over the whole cellular outgrowth a pseudoparenchyma from which the sporo- f'enous tissue Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Tubeuf, Karl, Freiherr von, 1862-.
