Slide labelled as Asterolampra decora from Oamaru, New Zealand. However I think this is actually A. vulgaris. Single example on the slide. Almost, but not quite intact (small crack in the rim near the 12 o’clock position). No makers name on this slide, but this is by Frederick Marshall. Olympus BHB microscope using 450nm LED light. 63x Leitz Pl Apo 1.4 objective, oil immersion. Olympus Aplanat Achromat condenser, oil immersion, oblique lighting. 2.5x Nikon CF PL photoeyepiece. Monochrome converted Nikon d850 camera. 19 images stacked in Zerene (Pmax).
