. Fig. 178.—Sorosporium saponariae (var. Lychnidis dioicae.) Mature spore-mass, and spores germinating. (After Woronin.) promycelium from the apex of which a single conidium is produced. Thecaphora lathyri Klihn. Spore-balls formed in the seeds of Lathyrus ^;?r^^!fws^s, and escaping as a brown powder on dehiscence of the pods. The spores germinate in water with formation of a promycelium bearing a single apical conidium, which produces a hypha, but never secondary conidia. In nutritive solutions the spores produce a mycelium from which conidia are continuously given off. Th. hyalina Fingerh. (

Woronin describes the spores as having germ-pores through which a septate germ-tube is emitted; the individual cells of the germ-tubes develop into liyphae, without formation of conidia. Th. affinis Sclnieid. In fruits of Astragalus glycyphyllus {\J.^. America). Th. Trailii Cooke. In flowers of Carduus heterophyllus in Scotland.
