Autofluorescence is reported for the first time in myxomycete fruiting bodies. Ultrastructure of stalked sporangia of Diachea leucopodia (Didymiaceae, Physarales) was studied using scanning and transmission electron microscopy, energy dispersive x-ray microanalysis and fluorescence microscopy.  External and internal properties of the peridium that surround the spores and capillitium exhibit autofluorescence. The stalk is composed of calcareous granules and energy dispersive x-ray microanalysis demonstrates that the elemental composition of the peridium, capillitium and stalk has varying concentrations of calcium.
