Fig. 51.—Cottony mold of lemon {Sclerotinia libertiana). are found irregularly-shaped, black, seed-like bodies called sclerotia from which another stage of the fungus develops. The same fungus also develops in the orchard soil during the rainy season and often becomes very abundant upon green-manure crops or other vegetation growing about the lemon trees, particularly upon the vetch. The sclerotia develop upon green-manure crops or directly upon the soil, the latter during the rainy season, and out of them grow little funnel- shaped toadstool-like bodies which give off the spores of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smith, Ralph E.
