Turkey Tail

Where it grows

Turkey tail is one of the most widely distributed fungi on Earth, fruiting year-round on dead hardwood — fallen logs, stumps, and the cut ends of firewood — across every continent except Antarctica. Tiered shelves often cover whole logs in striking bands.

How to recognise it

Thin, flexible, leathery brackets growing in overlapping rosettes. The upper surface is velvety to the touch and banded in dramatic concentric zones — brown, grey, blue, charcoal, cream, and tan — that resemble the tail feathers of a wild turkey. The underside is white with extremely fine pores; if you cannot see individual pores with the naked eye, you likely have the real thing.

Edibility & cautions

The flesh is too tough to eat. Prepared as a tea or extracted product. PSK (krestin), a standardised polysaccharide extract, is used in Japan as an adjuvant in cancer therapy. As with all medicinal mushrooms, check with a doctor before use, especially during cancer treatment.

Medicinal use

Best used as a long decoction or as a hot-water extract. Polysaccharides (especially PSK and PSP) are the most studied compounds and show immune-modulating activity in clinical trials.
