To provide a simple and nice-looking mushroom packaging structure for packaging a stock-picked mushroom in a standing state not contacting with an actual mushroom body as much as possible.

This mushroom packaging structure comprises a pot 20 for placing a stock-picked mushroom 10 in a standing state and a pillow package 30 which includes the pot 20 and the mushroom 10 and is tightly sealed with vertical heat welding closing parts 31, 32. The pot 20 is formed deep enough to store a lower part 11 but at least not a cap 12 of the mushroom 10. The package 30 is vertically long for forming a space 33 at the upper part of the mushroom 10 and has a size to wrap the pot 20 by being regulated in shape so as to copy the pot 20.
