Using stereomicroscopy, multiple individuals were found on detached Trichoglossus moluccanus feather, on the internal surface, at the intersections of the rachis and barbs. All appeared to be dead. Using a needle, one individual was removed for bright-field light microscopy.

Two sporing bodies. One sporing body with some evidence of animal eating it, the other sporing body with lots of pieces eaten off the edge of the pileus.

Interior with mottled core comprised of small dark brown nodules in white matrix - contrasting the the rest of the flesh which is yellowish.

Pore surface with a bloom that is disrupted when handled, as can be seen by the spotting on the underside view.
