'HAEKA. 551 to have an injurious effect on its host, beyond killing a few- isolated leaves. End. rubra Sehroet. occurs in leaves of Mcntlici aqimfica and Fcplis Portula. Phyllobium dimorphum Klel)S. Found in leaves of Lysi- machia Nummularia, AjiKja rcptan>i, Chlora serotina, Erythraca Centaurium. This endophyte may either penetrate into living leaves and there go through its life-history, or it may do so in dead leaves. The zygozoospores have only two cilia, and enter the leaves chiefly through the stoniata of the lower surface. Inside the leaf they form long filaments, which make their way between the elements into the vascular bundles of the leaf-ribs, and follow the course of the spiral vessels. Kesting-spores are formed, and give the veins of the leaf a rosary-like appearance. Male and female gametes are pro- duced from the resting cells, and copulate to form zygozoospores. The host-plants are not injured by this endophyte. Chaetophoraceae. Most of the species are aquatic algae which live independent or as epi])liyt(\s. Endoclonium polymorphum Frank (see Chlorosphacra rndo- phyta Klebs). This form lives endophytic and sometimes intra- cellular in living or dead leaves of Lrmaii. Entoderma Wittrockii Wille occurs inside the wall of Ectorarpvs (Fig. 327). Periplegmatium and Phaeophila live endophytic in living algae. Trentepohlia endophytica (IJeinsch).
