Fruiting Body

3–7 cm across, thin, convex to nearly flat, fan-shaped or shelf-like, often overlapping or even rosette-like, usually in groups. It could be resupinate if growing on the underside of the host/substrate. Margin is white, blackening with age. Its skin is faintly hairy (tomentose) with faint concentric zones at first, could be almost completely hairless and suede-like with age.

Pores

Tubes up to 1 mm long, pale grey to grey. Pores 4–7 per mm, angular to irregularly rounded, smoke-grey, blackening if damaged.

Flesh

Thin, elastic and has two layers. Under the skin it is whitish, while greyish to blackish above the tubes.

Habitat

On the dead wood of hardwoods, especially beech, but rarely on conifers. Saprotrophic, causes white-rot.

Possible Confusion

Especially younger fruit bodies could be easily confuse with Turkey Tail (Trametes versicolor), pictured, but its skin has more colour and its pore surface is much brighter white.
Its close relative, Big Smoky Bracket (Bjerkandera fumosa) somewhat bigger (4–10 cm across), its cap is paler in colour and growing mostly on sycamore, but also on alder, sweet chestnut or other hardwood genera. There is a dark layer between the two layers of its flesh.

Spore Print

Spore print is white. Spores elliptical, smooth and colourless (hyaline).

Taste / Smell

Inedible, tastes sour, but it has a somewhat sweet smell.

Frequency

Common and widespread.

    Can these grow out of brickwork? Restoring a 140year old building and something similar is growing from the bricks

      Hi Ben,
      Not really. It is a saprotrophic species, growing on already dead wood material of hardwoods.
