Thin-walled Maze Polypore

Daedaleopsis confragosa, commonly known as the thin-walled maze polypore or the blushing bracket, is a species of polypore fungus in the family Polyporaceae. The species was first described from Europe in 1791 as a form of Boletus, and has undergone several changes of genus in its taxonomic history. It acquired its current name when Joseph Schröter transferred it to Daedaleopsis in 1888.

A plant pathogen, it causes a white rot of injured hardwoods, especially willows. The fruit bodies are semicircular and tough, have a concentrically zoned brownish upper surface, and measure up to 20 cm (8 in) in diameter. The whitish underside turns gray-brown as the fruit body ages, but bruises pink or red. It is found all year and is common in northern temperate woodlands of Eurasia and eastern North America.
