Mushroom Packaging?

This is a video I found during a late night TED Talk watching-spree. The video features Eben Bayer who is a environmental activist that is selling the idea of using mushrooms as a new way to package items that need to be shipped.

Eben Bayer has many other types of projects, which are featured on his blog http://ebenbayer.com/, but his biggest contribution I could find is this mushroom plastic concept.

Overall I agree with Eben on the fact that Styrofoam  is very bad for the environment. Now using mushrooms on the other hand is pretty far fetched, although I am open to the idea. For whatever reason I get the feeling of ordering some clothes on Amazon and receiving a moldy package full of mushrooms and wet clothes.... But if I am proven wrong on the idea, this would be great both for the environment but also the retailer because they can green-up their brand by providing this service
