The shedding and the fixing of spores liberated from sporangia on the protonema-like body were studied;
1) The shedding begins after sunrise and continues for two hours on fine days, but on cloudy days the shedding is seen at nearly eleven o'clock. In the former case could not be any shedding observed at night (Fig. 4).
2) Spores fix themselves within two minutes on contact with a substratum. (Fig. 2).
The fixing of spores occurs in the greatest number just after shedding and decreases to about half one hour after shedding. (Fig. 3). The fixing ability of spores is unchanged in darkness.
3) The diameter of spores was from 8.7μ to 13.7μ (mean diameter is 10.7μ).
