Polyporus squamosus

Polyporus squamosus (NL: Zadelzwam / EN: Dryad’s saddle, Pheasant’s back mushroom / DE: Schuppiger Stielporling, Schwarzfußporling / FR: Polypore écailleux) is a basidiomycete bracket fungus. It has a widespread distribution, being found in North America, Australia, Asia, and Europe, where it causes a white rot in the heartwood of living and dead hardwood trees. The name "Dryad's saddle" refers to creatures in Greek mythology called Dryads who could conceivably fit and ride on this mushroom, whereas the pheasant's back analogy derives from the pattern of colors on the bracket matching that of a pheasant's back. This mushroom is commonly attached to dead logs or stumps at one point with a thick stem. Generally, the fruit body is 8–30 cm across and up to 10 cm thick. The body can be yellow to brown and has "squamules" or scales on its upper side. On the underside one can see the pores that are characteristic of the genus Polyporus; they are made up of tubes packed together closely. The tubes are between 1 and 12 mm long. The stalk is thick and short, up to 5 cm long. The fruit body will produce a white spore print if laid onto a sheet of paper. They can be found alone, in clusters of two or three, or forming shelves. Young specimens (as in this image) are soft but toughen with age.
