SEM observation and X-Ray energy dispersive analysis of peridial calcareous deposites in two myxomycete species
In this paper the differences of calcareous crystals and chemical element were investigated in the fruiting body of two related myxomycete genera--Diderma and Didymium . Didymium iridis and Didenrut hemisphaericum were observed as representative species in two genera under scanning electron microscope(SEM)and analyzed by X-ray energy dispersive analysis (EDS). The results showed that there were obvious differences between the two species in the type of calcareous deposits of peridium surface.In D. hemisphaericum, the calcareous deposits were globular amorphous, while they were in the form of rhombic crystalline in D. iridis . By using X-ray energy dispersive analysis (EDS), it was determined that calcium was the most abundant mineral deposited in the peridium of the two species besides carbon and oxygen. Furthermore, in D. hemisphaericum, aluminum was detected in trace amounts, whereas phosphorus and sulfur instead of aluminum were detected in trace amounts in D.iridis.
