Mended from five pieces; lower right half and upper right corner missing. Original cut edges at left, top and bottom; where preserved at right a very thin edge. Curved: on convex side, thin vertical lines; on back, concave sides, rough hacked surface.
Perhaps patch for a column drum. Estimated diameter seems to be well over 0.57m.
Lightweight grayish-yellow poros.
