A SEM Study of Genus Badhamia (Myxomycetes)
摘要
Capillitial threads, c-granules and other parts in a sporangium of 17 species of Genus Badhamia were investigated in detail using SEM apparatus and a few new findings were obtained. Capillitium is composed by branching and anastomosing threads and plates at an interconnection point. Capillitium of B. affinis and some species are club shaped threads. The one of B. crassipella and some species are thick threads and lump shaped plates. Other species have slender threads, flat plates and other types. Usually capillitium is evenly positioned in a sporangium. Capillitial threads of B. dearnesii and some species are mainly positioned in an upper portion and gradually decreased to a lower portion. Species belong to genus Badhamia have c-granules on a peridial surface and an inside of a capillitial tubular thread. C-granules is globose, smooth on the surface, 0.3-1.9 μm in diameter. Usually the surface of a capillitial thread has numerous hemispherical processes traced by c-granules inside. Peridium has many small pits on the surface. A pit connects into a capillitial tubular thread extended to the inside of a sporangium. C-granules on a peridum and the one in a capillitial tubular thread are connected with each other through a pit on a peridial surface.
