The scaly stalk porling or scaly porling for short ( Cerioporus squamosus , syn. Polyporus squamosus ) is a type of fungus from the family of stem porling relatives (Polyporaceae), which also affects living trees and can develop from very large fruiting bodies. Due to the black stalk base in older fruiting bodies , the species is also known as the scaly black-footed spore .

Macroscopic features

The hat becomes extremely large with a width of 10-30 (-60) cm. At first it unfolds in a flat fan shape, later bulges in a funnel shape and often appears kidney-shaped in plan view. The upper side is yellowish, later pale brown in color and covered with concentric, adjoining and brown scales. The white to pale yellowish tubes on the underside of the hat are 0.2–1 cm long. They have irregularly angular and up to 2.5 mm wide mouths. The spore powder is white. The thick, short and squat handle measures 2–6 cm in diameter. It is usually attached to the side of the substrate , less often in the center. In old age it has a black stem base, the blackening can pull up the stem to the middle. Young the meat is thick, juicy and soft, with age it becomes increasingly corky and tough. The intense flour- to cucumber-like smell is striking, the taste is nutty.

Microscopic features

The spores are elliptical, smooth, and measure 10-16 x 4-6 micrometers.

Species delimitation

A mix-up is hardly possible due to the conspicuous appearance.

Smaller specimens can be confused with the sclerotia stalk porling . This usually has a centrally stalked fruiting body, grows mainly on fallen branches, has a ciliate brim and has no odor of flour.

Ecology and phenology

The fruiting bodies of the scaly stem porlings can be up to 40 cm wide.

The fungus occurs on the trunks of dead or severely weakened deciduous trees and causes white rot , i.e. That is, it preferentially breaks down the lignin in wood . Its occurrence in connection with a very rapid growth in May and June is striking, more rarely it can also appear from April to September.

meaning

etymology

The Latin squamosus means "scaly".

Food value

The scaly Porling can be eaten young, but its culinary value is classified as rather low. With age it becomes inedible due to its increasingly corky and chewy consistency.
