When Fuligo cinerea (Schw.) Morg. of Taiwan arrived in my laboratory, it was a huge, yellow mass of plasmodium. In the next day it changed its color into brown or black and aethalia of various sizes were observed. Spore germination revealed a germination rate of 50%, which was probably determined by the age of spores. Swarm cells emerged by a slit. in the wall usually one cell escaped from one Spore. Biflagellated swarm cells produced synchronously were observed. Both yellow and colorless plasmodia were observed. Veins, fans and clamps were vivid and vigorous streaming occurred nearly in all the cultures. Myxamoebae of both large sized and smaller ones were observed. Sclerotia of angular cysts and microcysts often formed under unfavorable conditions. When the plasmodia became drier and smaller, fructification and sporulation followed. It takes about 18 days to complete the life cycle of Fuligo cinerea. |
