Daedaleopsis confragosa

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....read more on Wikipedia.
