The leaf-parenchyma is permeated with mycelium, and sori are formed on the lower epidermis. A, urcdo-sorus ; B, teleutospore-sorus, many spores of which have germinated and given off promycelia with sporidia. (v. Tubeuf del.) Brown spots may l)e found on the leaves of the Cywiarhum'^ during July, August, and September (Fig. 214). On examina- tion of the spots with a lens, the leaf-epidermis will be found ^ A very common plant in Europe though not indigenous to Britain. (Kdit.).
