Plant diseases; Parasitic plants. KXOBASIDIUM. 425 from each a spindle-shaped spore is abjointed (Fig. 257). The basidiospores divide in water by formation of cross-septa, and a germ-tube arises from each terminal cell. On a young leaf of Vaccinium the germ-tube penetrates and gives rise to a mycelium (Fig. 258); on other substrata the germ-tube sprouts into se\'eral very fine .sterignuita, from tlie extremi- ties of which a series of conidia are abjointed; the conidia may give off secondary coni- dia, perhaps also tertiary. In nutritive solution, IJrefeld ob- tained an increased number of germ-tubes and a continuous production of conidia; in air, conidia were produced on conidia, but inside the solution the conidia gave off hyphae from wliich new conidia Fk:. iitl.—KxohamUvm vaccinii.
