(Photograph by F. C. Stewart) time the Glceosporial stage upon growing parts. The ascigerous stage develops as a small fungous body of rapidly growing tissue, completely immersed in the leaf, and more or less surrounded by the old hyphse of the Glceosporial form. With further develop- ment the epidermis is ruptured and the apothecium opens as a fleshy disk-shaped structure, the basal portions of which consist of more or less pseudoparenchymatous tissue from which arise numerous asci and paraphyses. The basal portion remains in part surrounded by thick-walled cells of the old mycelium, as.
