Observation 145162: Postia caesia group

White/clear gelatinous polypore growing on a stick of unknown type. The very top of the polypore had fine hairs sticking up and the protruding shelf area was quite gelatinous. Underside looked like fine teeth. Turned bluish with age. Only a couple centimeters (4-6) across. Looks to be a “baby” blue cheese polypore (Oligoporus caesius).
