How to describe Symbiotic entity wildshape from the spore druid? [closed]

The spores druid have a new type of wild shape the symbiotic entity. In the rules is stated:

At 2nd level, you gain the ability to channel magic into your spores. As an action, you can expend a use of your Wild Shape feature to awaken those spores.

But wild shape is like a metamorphous trait, right? And what exactly is "awakening the spores", you became a giant mushroom? Mushrooms are grown on your back? But if they just grow with the wild shape how you can spread spores? It’s just a random question, but I like to describe every single ability that I use.
