Natural himotoshi thanks to the curved foot of the larger mushroom.
Japan, 19th century.
Note the realism of the gills and the surface of the larger cap, which is particularly well polished.
Also note two cracks in the wood, one in the cap of the large mushroom, and a more discreet one on the cap of the small one. Diameter: 4.8 cm.
