EXOBASIDIUM. 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 several very fine sterigmata, from the extremi- ties of which a series of couidia are abjointe

In nutritive solution, Brefeld 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 which new conidia Fig. •IbT.—Exohasidium vaccinii.
