Fuligo septica var flava
I found this in a local wood this morning. It is the yellowest form of the species. This is a young specimen, which probably was not visible the previous day. It is a new record for that site.
Olympus EM-1, (aperture priority), Olympus 4/3 50mm f2 macro, 1/125 at f10 ISO 1600, hand-held.
The stereo is crosseye. Different focus for the two images gives a rally deep 3D DOF.
