Maitake
Grifola frondosa
fungusMaitake is a medicinal mushroom that grows as a large, clustered fruiting body with fan-shaped caps that range from gray to brown. Known as 'dancing mushroom' in Japanese, it is highly prized for both culinary and medicinal applications. This wood-decay fungus typically fruits in fall and can produce several pounds of mushrooms from a single colony.

Growing Conditions
Soil
Growth Stages
Spawn Running
4-12 weeksMycelium colonizes the sawdust substrate, appearing as white thread-like growth throughout the medium
Maintain 55-75°F (13-24°C), keep substrate moist but not waterlogged, ensure good air exchange to prevent contamination. This phase takes 4-12 weeks depending on spawn rate
Pinning Initiation
7-14 daysTiny mushroom primordia (pins) form on the substrate surface, typically triggered by temperature drop and increased humidity
Drop temperature to 55-65°F (13-18°C), increase humidity to 85-95%, provide 12 hours of light daily, and increase fresh air exchange. Mist 2-3 times daily
Fruiting Development
2-4 weeksPins enlarge into clustered fan-shaped caps with a characteristic gray-brown color. Clusters can weigh 0.5-2+ pounds
Maintain 55-65°F, humidity at 85-95%, continue misting 2-3 times daily, ensure good air circulation. Reduce misting slightly as caps expand to prevent bacterial issues
Maturity & Harvest
Variable; harvest when readyMushroom caps flatten and pores appear on the underside. Clusters reach full size and are ready for harvest before spore release
Harvest at full size but before caps begin to upturn (which indicates spore release). Cut at the base with a sterile knife. Avoid bruising
Recovery & Second Flush
2-4 weeks between flushesAfter harvest, mycelium recovers in the substrate for a second or third flush of fruiting
Reduce misting, allow substrate to dry slightly, then repeat fruiting conditions. Second flushes are typically smaller than the first

Harvest Tips
Harvest Maitake mushrooms when the caps are fully expanded but before they begin to curl upward (which indicates spore release). Grasp the cluster at the base and cut cleanly with a sterile knife or snap off carefully. Harvest in the morning when hydration is highest. Mushrooms can be dried or used fresh; they store in the refrigerator for 1-2 weeks in a paper bag. Second and third flushes typically follow within 2-4 weeks after harvest with proper recovery conditions.
Fun Facts
- 🌱 Maitake translates to 'dancing mushroom' in Japanese because, according to legend, people who found it in the wild would dance with joy—it was highly prized and sometimes worth its weight in silver during feudal Japan.
- 🌱 A single Maitake fruiting body can produce multiple pounds of mushrooms and is one of the largest wood-decay fungi, with wild specimens sometimes weighing over 100 pounds.
- 🌱 Maitake has been cultivated commercially in Japan since the 1970s and is now the most widely cultivated medicinal mushroom worldwide, with decades of scientific research supporting its traditional uses.
