RMRH0WN3–. Bulletin. Agriculture -- New Hampshire. 118 N. H. AGR. EXPERIMENT STATION [Bulletin 144 Thick walled spores known as chlamydospores are common (Fig. 11). These probably assist in carrying the disease over the win- ter. The mycelium of the fungus probably plays a part in this connection also, as it has been found that it is not killed by a prolonged exposure at very low temperatures. The fungus grows well on various media in laboratory cultures. The manner of spore production in these cultures is shown in Fig. 12. Small knobs are produced on the side of the hyphae, and from Fig. 10.—Spores of

In old cultures on various artificial media, large, thick-walled, intercalary,'brown, spore-like bodies are some- times present in abundance. They were also obtained easily by transferring bits of mycelium to sterile water. They have been observed in agar cul- tures that have become contaminated by bacteria, being found more especially near the bacterial colonies.
