Fortunately the resolution of the 500mm lens is surprsingly good, I locked up all the tripod screws and had some fotos taken of these whitish blobs on a dead log on the ground. Kindly see if you can make anything out of these tele-macro shots ! Thank you.
Interesting! There are a number of polypore species that are both resupinate and forming small shelving "caps." I don't think I can ID this from a photo, but the growth pattern and substrate will likely narrow down the possibilities.
Oh.... after you pointed it out, I now can see they are forming tiny shelves ! I guess they might be polypores still in Kindergarten.
