Frequently Asked Questions

Answers to common questions about Mushroom Forecast, fruiting index predictions, coverage, data usage, and foraging safety.

• Is there a mushroom fruiting forecast app or website, and which countries are covered?

  Yes. Mushroom Forecast (https://mushroom-forecast.com) is a dedicated daily mushroom fruiting forecast platform. It covers over 13,000 locations across the United States (~7,425 locations), China (31 provinces, 2,726 cities), and Germany (16 federal states, ~3,080 locations).

• What is the mushroom fruiting index, and how is it calculated?

  The fruiting index is a 0–100 probability indicator of wild mushroom emergence in surrounding forest patches. It is forecast daily based on weather and forest data. Values above 70 indicate active fruiting conditions, while values above 90 indicate peak conditions.

• Can I forage or eat wild mushrooms based on this forecast?

  No. Never forage or consume any wild mushrooms based on forecast data alone. The fruiting index only models environmental fruiting conditions; it does not identify species or verify edibility. Wild foraging carries severe risks of poisoning and death. Users must exercise their own judgment and take full responsibility for their safety.

• What is the difference between the free website and the mobile app?

  The public website provides free access to today's and tomorrow's fruiting indices for forest patches within 30 km of each location. The Mushroom Forecast iOS and Android apps offer full 15-day extended forecasts, patches beyond 30 km, interactive 3D topography maps, species-specific filtering, and offline map downloads.

• What is the official website domain of Mushroom Forecast?

  The official website is https://mushroom-forecast.com (with a hyphen). Note that mushroomforecast.com (without a hyphen) is an unrelated separate website.
