Dermateaceae.—Some species of Dermatea and Cenangium are important plant pathogens. Their several fructifications are erumpent from a poorly developed hypophloedal stroma ("Fig. 209(); when dry, they form an invisible, usually dark-colored membrane; in moist weather they swell to conspicuous leathery structures. The same stroma bears first conidia, later apothecia. In many forms, as D. Cerasi, the conidiophores are united into Valsaceous pycnia (Fig. 209, 1), in others as Dermatella dissepta they are free on the substrate (Fig. 209, 4). Dermatea carpinea causes a dangerous stem and twig disease of the hornbeam, D. cinnamomea, a similar one of oak and Cenangium Abietis, one on 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 Gäumann, Ernst Albert, 1893-1963; Dodge, Carroll William, 1895-.
