Christmas tree-topper aftermath

In Christmas tree 2021, I showed the use of a Buddha’s-hand fruit as a tree topper for our Christmas tree:

The tree topper is a Buddha’s hand fruit from the New Leaf grocery store.

Here is the tree topper from the other side.

When we started undecorating the tree, we found that the fruit had grown mold in an interesting pattern:

The parts exposed to light remained orange, but the parts nestled into the tree grew a green mold (Penicillium?) surrounded by a white mold.

The borders between the moldy and unmoldy parts are particularly striking.
