In addition to the ax, knife, quiver, and arrows, Otzi had shoes, clothing, two birchbark canisters, a sheath, a bowstave, miscellaneous small tools, some berries, a piece of ibex meat, and two spherical lumps of birch fungus, each about the size of a large walnut and carefully threaded with sinew. One of the canisters had contained glowing embers wrapped in maple leaves, for starting fires. Such an assemblage of personal effects was unique. Some of the items were, as it were, really unique in that they had never been imagined, much less seen. The birch fungus was a particular mystery because it was obviously treasured, and yet birch fungus is not known to be good for anything.
