Description

Antrodia albida is an annual polypore that lives mainly on trunks of broadleaf trees. Occasionally it moves onto conifers, but that's not its typical choice.

The fruiting bodies are flat and attached to the substrate. They spread in overlapping, tile-like groups or in long rows along the bark. Young ones are whitish, fading to pale yellow with age. Moderate size — up to 8 cm long, 2–3 cm wide.

In Ukraine there's a known find from Zakarpattia. Overall, the species is present on every continent except Australia — a typical decomposer of broadleaf wood in the temperate zone. It has no culinary value; its role in the forest is breaking down dead trunks.

Cap

Fruiting body annual, spread out. Caps up to 8 cm long, 2–3 cm wide. Color: whitish at first, turning pale yellow with time. Often grows in overlapping, tile-like groups or long rows.

Hymenophore

Tubular hymenophore. Spore print white. Spores cylindrical, colorless, 8–14 × 3.5–6 µm.

Stem

No stem. The fruiting body is attached to the substrate by its whole base.

Flesh

flesh thin, leathery. Whitish when young, yellowing with age.

Smell

No distinctive smell.

Frequently asked questions

Can you eat it?

No. It's a tough polypore with no food value.

Is it dangerous for a garden?

As a decomposer of dead wood — no. If you see it on a healthy garden tree, that's a sign rot is already underway inside the trunk, and the tree needs inspecting.

Where should you look for it?

On trunks of broadleaf trees — oak, birch, aspen, less often on conifers. In old forests and on fallen logs.

In which regions of Ukraine?

Known finds come from Zakarpattia. Elsewhere in the country it's rarely documented, though in theory it may occur in other western and Polissia forests too.

When can you see it?

The fruiting bodies are annual, but dried remains stay on the trunks for a long time. Fresh white layers grow during warm, damp spells.

Is autumn the best time to look?

In late summer and autumn the fruiting bodies are most noticeable. In a drought they shrink and blend into the bark.

What is it confused with?

With other thin white polypores of the family Fomitopsidaceae — especially the genera Antrodia and Amyloporia. Exact identification is by spores under a microscope.

How do you tell it apart from its conifer relatives?

Antrodia albida sticks to broadleaf trees — that's your first clue. Found a white polypore on an oak or birch? Most likely, it's this one.

Is Antrodia albida edible or poisonous?
Antrodia albida is inedible. Before eating any wild mushroom, always double-check current information in reliable sources and consult an expert.
Does Antrodia albida have gills or pores?
The spore-bearing surface (hymenophore) of Antrodia albida: pored.
What does the cap of Antrodia albida look like?
Fruiting body annual, spread out. Caps up to 8 cm long, 2–3 cm wide. Color: whitish at first, turning pale yellow with time. Often grows in overlapping, tile-like groups or long rows.
What does the stem of Antrodia albida look like?
No stem. The fruiting body is attached to the substrate by its whole base.
