Funghi
Ganoderma tsugae
A tier
Ganoderma tsugae is hemlock reishi—a North American species growing on hemlocks with a reddish varnished cap similar in look to Asian reishi but ecologically distinct. Foragers dry it for bitter teas parallel to lingzhi use; flavour is woody-bitter with local forest character. It is the reishi many temperate North American woods actually offer. Confirm identification; use only dried mature brackets for decoction. Not a substitute for soft edible mushrooms. Cultivation on hemlock or suitable woods exists among specialist growers.
