PSEUDOPEZIZA (FcKL.) Ascophore erumpent, sessile, glabrous, minute; asci clavate, 4-8 spored; spores hyaline, smooth, elongated, con- tinuous or i-septate ; paraphyses present. Fig. 81.—Psciidopeziza trifolii. i, clover leaf infected ; 2, fungus bursting through epidermis of leaf; 3, ascus with spores, also two paraphyses. Figs. 2 and 3 mag. The ascophores originate in the tissues of the host, usually the leaves. Some are parasites, others saprophytes. Dis- tinguished by the ascophore developing in the tissue of the host, and bursting through to the surface at maturity. Clover leaf spot, caused by Pseudopeziza trifolii (Fckl.), is at times very injurious to the clover {Trifoii2im) and
