LATIN NAME: Grifola frondosa
COMMON NAME: Maitake Mushroom
Species Profile
Grifola frondosa, maitake, grows in large, ruffled clusters at the base of oaks and other hardwoods in temperate forests of Asia, Europe and North America. Its name means dancing mushroom in Japanese, because, as the story goes, foragers who found a big cluster danced with joy at their luck.
A single wild cluster can weigh several kilograms, with dozens of overlapping grey-brown fronds that smell faintly of the forest floor.
Science & Biotechnology
Maitake is best known in research circles for its beta-glucan fraction, often called the D-fraction, which has been studied extensively in laboratory and animal models for immune-related activity. The mushroom is also a good source of minerals and ergosterol, the precursor to vitamin D.
Unlike many medicinal mushrooms, maitake is fully delicious, which makes it easy to enjoy as food rather than only as an extract. Commercial cultivation on sterilized sawdust blocks is well established, and cultivated quality now rivals wild.
Uses & Benefits
In the kitchen, maitake is superb: tear the fronds apart and roast, sauté or grill them until the edges crisp, and they develop a deep, savory, almost meaty flavor. It also makes an excellent soup and hot-pot mushroom.
Dried maitake rehydrates well and its soaking liquid is a richly flavored broth in its own right; the dried form is the most practical way to keep this seasonal mushroom year-round.
Cultivation
Maitake is cultivated from spawn on supplemented hardwood sawdust blocks. The blocks are incubated warm until fully colonized, then moved to cooler, humid fruiting rooms where the clustered fronds develop over several weeks.
Growers harvest when the fronds are fully expanded but still firm at the edges; over-mature clusters turn pale and floppy and lose both texture and flavor.
Our Take
Maitake wins the prize for the mushroom that pleases everyone: genuinely gourmet on the plate, genuinely interesting in the research literature. If you only try one medicinal mushroom as food, make it this one.
