Chondrostereum purpureum, commonly known as Silverleaf fungus or Purplepore bracket, is a wood-decaying fungus belonging to the family Stereaceae. It is characterized by its semi-circular, purple to lilac, and velvety fruiting bodies, which can grow up to 8 cm in width and 1-2 cm in thickness. The upper surface of the fruiting body is covered in a dense, velvety layer of short hairs, while the lower surface features purple or lilac pores with a white to grayish margin. The fruiting bodies of C. purpureum are typically thin and flat, with a leathery texture. The spores of Chondrostereum purpureum are ellipsoid, smooth, and hyaline, measuring 5-7 x 2-3 µm. The spore print is white, although it can be difficult to obtain due to the resupinate growth habit of the fungus. Chondrostereum purpureum is a saprotrophic and weakly parasitic fungus, primarily decomposing dead hardwood trees or living trees with weakened immune systems. It is commonly found on species such as apple, cherry, plum, and poplar. The distribution of C. purpureum is widespread, occurring in North America, Europe, and parts of Asia. It can be found in a variety of habitats, including forests, parks, and orchards. The fruiting period of Chondrostereum purpureum typically occurs from late summer to autumn, depending on local climate and weather conditions. While not considered edible, C. purpureum is not known to be toxic. However, it is not recommended for consumption due to its tough, leathery texture and potential allergenic properties. Chondrostereum purpureum is known to cause silver leaf disease in plants, particularly in fruit trees. The fungus invades the tree through wounds, causing the leaves to turn a silvery-gray color and eventually leading to tree death. Research has shown that C. purpureum produces bioactive compounds with antimicrobial, antiviral, and antitumor activities, which may have potential applications in medicine and biotechnology.
