How far you can sell is set by how long the mushroom lasts, not by the road.
ICAR-DMR's farmer folder gives button mushroom about 12 hours at ambient temperature and 2 to 3 days in a refrigerator. The 2011 manual gives fresh oyster 24 to 48 hours at room temperature and milky mushroom 3 to 4 days. Paddy straw mushroom is the trap: DMR's bulletin says it must not be held at 4 °C because it breaks down; hold it at 10 to 15 °C for about 3 days.
