description Fistulina hepatica Overview
Fistulina hepatica, commonly called the beefsteak fungus, is a fleshy bracket fungus found mainly on living or dead broadleaf trees. It is especially associated with oaks and sweet chestnuts. The reddish fruit body can exude a red liquid when cut, while the interior often shows pale fibers and a marbled appearance that evokes raw meat. It is of interest to mushroom foragers and wood-decay specialists, although identification and edibility should be assessed carefully.
help Fistulina hepatica FAQ
Why is Fistulina hepatica called the beefsteak fungus?
Because its reddish fruit body looks and even bleeds like raw meat — the fresh flesh exudes a red juice when cut, and the interior has a marbled, meat-like texture. The scientific name hepatica refers to liver, reinforcing the same resemblance.
Can you eat beefsteak fungus?
Yes, Fistulina hepatica is generally considered edible, especially when young and thoroughly cooked. It has a strongly acidic, sour flavor, so foragers often slice and marinate it before cooking, and older brackets become tough and fibrous.
Does the beefsteak fungus kill oak trees?
It causes a brown rot in the wood of living oaks and sweet chestnuts, its favorite hosts, gradually degrading the heartwood. Paradoxically, this decay produces 'brown oak' timber, a richly colored wood that is actually prized by cabinetmakers and furniture makers.
Where and when should I look for beefsteak fungus?
Look on the lower trunks of mature oaks and sweet chestnuts in Europe, typically from late summer through autumn. The tongue-shaped brackets can reach about 30 cm across and grow directly from the bark of living or dead broadleaf trees.
