Dear colleagues, With a small team I have studied the feces of an Alaskan mammoth. Among the macrofossils were objects that I had never seen before. See attached ppt. In first instance I thought it was a fungal fruit-body, but experienced mycologists do not recognize it as such. Description: Unidentified macrofossils Globose to ellipsoid closed bodies (230-)330-470(-580) µm, sometimes elongated with several lobes, measuring up to 1600 µm (total length). Outer wall irregularly structured, yellow-brown, ca. 12 µm thick. Broken bodies showing ca. 1µm thick inner wall (not attached to outer wall); hyaline with granulate structure, filled up with densely packed round spores (7-)10-11(-14) µm in diameter. Any suggestion for identification is welcome!
