This name for this is Ganoderma applanatum – doesn’t really roll of the tongue. Instead of the scientific or commonly used name, make one up. In this case, how about ‘knick knack shelves’?
Here are a few other examples, but I’m sure you can top these.
Forest Accordion
Yellow Dog
This jelly fungi has a common name that suits the approach of Halloween – orange witches butter.
Blue Whale Pod
???
Do you have a name for this one, and perhaps another for the superhero action figure on the knick knack shelf?

Beautiful! Best time of year for spotting fungi! My guess – Gymnopus dryophilus? Were you near oak trees?
Mostly maples but there were oaks in the area.
Ok, I re-read the instructions. You clearly weren’t looking for formal names. Here is my new name for it: Brown eyed ‘gill’. Hehe
Perfect name – a play on words name for a play outside pic. Thanks!
Looks to me like a pancake on a stick!
love it
Is the action figure wearing a space suit ? He looks like Felix Baumgartner.
Yes, he is wearing a space suit. So in this case, I guess he would be a mushroom jumper instead of a BASE jumper.
