Somewhat diagrammatic (After Woemle.) and during rain swell up into long club-shaped sporophores, containing long-stalked, spindle-shaped teleutospores, some thick- coated, some thin. The sporophores swell and ultimately form a common mass in which the teleutospores germinate. The spores have four germ-pores, each capable of giving ofif a promycelium with pointed sterigmata producing sporidia, which are cast loose and distributed by wind. Germination of sporidia takes place on leaves, cotyledons, petioles, and shoots of various Pomaceae, where they may induce swellings or curvature, often to a considerable 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, 1862-1941; Smith, William G.
