This name is currently regarded as a synonym of Cavinula cocconeiformis (W.Gregory ex Greville) D.G.Mann & A.J.Stickle. No mounters name, but this was prepared by Samuel Henry Meakin. Olympus BHB microscope using 450nm LED light. 63x Leitz Pl Apo 1.4 objective, oil immersion. Olympus Aplanat Achromat condenser, oil immersion, brightfield lighting. 2.5x Nikon CF PL photoeyepiece.
