Observation 198370: Tineidae

Observed small 3 inch diameter polypore on unknown tropical tree over two weeks.
Four soft lobes grew to over 2 inches during this time. I guess an insect created them. I cut the tip off one and found nothing visible inside.
I have been told that on the night before or early morning hours of March 13, 2014, the other tips had all opened at the bottom and a local researcher found nothing was found inside any of them.
I do have the desiccated tip.

but I couldn’t say much more. I have found much smaller and more numerous but structurally similar growths on the underside of Ganoderma spp. in the Neotropics. They appear to be the accumulated remnants of some burrowing bug, but they are actually the house/shell/exterior of the bug itself, which latches itself onto the hymenium of the polypore, though to what end I am not sure. Whenever I try to pull a few off, they’re usually very firmly attached, but just in the past few days while processing material from a recent collecting trip, I noticed one start to move. never did get a good look at the occupant, but it was definitely alive and ambulatory, and appeared to have released whatever death grip it once had on the fungus to which it was clinging.

just one of many wonderful little neotropical fungal ecology rabbit holes to fall down into.
