Four families are included in this order, and these families include a considerable number of important genera of fungi, which specifically are the cause of important plant diseases. Phyllosticta is a genus, the species of which are confined to leaves, and they produce characteristic leaf spots on a great variety of plants. The specific name of the fungus is usually derived from that of the host plant attacked, as for example, Phyllosticta catalpa, which. Fig. 103.—Six j3en Davis apples showing apple blotch {Phylloslica solilaria). (After Scott, W. M., and Rarer, J. B., Bull. 144, U. S. Bureau of Plant Jnduslry. March 6, 1909.) grows on the leaves of the catalpa. The group has been monographed systematically by J. B. Ellis. The spores are small, egg-shaped or elongated, unseptate and in color pale green, or hyaline, produced in pycnidia. The most important species of this genus are Phyllosticta ampelopsidis on the Virginia creeper (A mpelopsis); catalpm on catalpa leaves; labrusccB on the leaves of the grape; pavicB on horse chest- nut leaves (Fig. 102); Phyllosticta solilaria E. and E. (Figs. 103 and 104) is the cause of apple blotch, and violm on violets. The conidio-.
