ENTOMOSPORIUM 453 Sorauer has described an ascigerous fungus he called Stigmatea mespili, which occurred on dead leaves along with Entomosporii/m, and which he considers as being the higher form of the last-named fungus. He offers no cultural evidence, however, of this supposed relationship, which thus rests only on juxtaposition of the two. The black perithecia are flattened and have an imperfectly formed mouth. Spores several-celled, the minute, lateral cells springing from the median septum, very small, lateral, and terminal cells each terminated by a slender hyaline hair, 18-20 X 10-13 Fig. 138.—Rntomosporiiim maculatum. i, quince leaf diseased ; 2, spores of fungus, highly mag. Spraying with Bordeaux mixture checks the spread of the disease. The dead, diseased leaves should be burned or buried, the diseased shoots should also be cut off. Duggar has the following remarks on this fungus. In the nursery the principal damage is done to seedling pears, and further injury is usually to be attributed to the leaf-spot, Septoria piricola. As previously mentioned, the budded stock is much less frequently affected by the leaf blight, Entomosporium juaculatum. Seedling pears throughout the State, and generally throughout the country, suffer seriously from it. The youngest foliage is first affected, and often the leaves.
