Daedalea quercina (L.) Pers., Syn. Meth. Fung. (Gőttingen) 2: 500 (1801)

 

The species of D. quercina are saprobic; growing alone or in small groups without a distinct cap on decaying wood. It prefers a Quercus wood as a host; however, found on the other hardwoods also; annual or perennial.

It causes a brown rot of the heartwood1. The specimen was collected from Manikgad (Raigad district), Kanakeshwar (Alibag), Mahrashtra Nature Park (Mumbai) and Dapoli.

Morphology:

The fruiting bodies are sessile and fan shaped, 30-200 mm in diameter and up to 89 mm thick. They are found to be grown alone or in groups, usually in a tiered arrangement. The upper surface of the cap is whitish when fresh, however, upon drying shows yellowish to various shades of brown. The lower surface, white to tan in color, is initially porous, but at maturity it shows blunt partitions. This results in the characteristic maze-like appearance1, 2.

Culinary value:

Inedible as food

Medicinal importance:

A compound Quercinol isolated from D. quercina showed anti inflamatory activity3.

Industrial importance:

  1. Daedalea quercina was investigated for application in bioremediation of a variety of toxic chemical pollutants4.
  2. The lignin-degrading enzyme laccase, isolated and purified from D. quercina, had shown its potential use in biodegrading a variety of toxic dyes and pigments5.

 

Unique features:

Lack of information

Interesting facts:

Fruit bodies are used as a natural comb, applied on horses for brushing their skin. In England, smoldering fruit bodies were used for anesthetizing bees2.

  1. The hosts of D. quercina in vitro are very well studied. The study was carried out in vivo to decide the group of tree species which will be decayed by D. quercina. It was found that the trophic preferences of D. quercina are much wider than in vivo6.
  2. The insect assemblages associated with the fruit bodies of D. quercina were investigated. However, probably because of tough fruit bodies dominance of Lepidoptera was observed. Also, this species was found to be distributed in low density and thus, making it challenging for any specialized insect to maintain viable populations7.
  3. The study was conducted to evaluate the biosorption of aluminum, cadmium, copper, lead and zinc in native fungal pellets of D. quercina and the stress response of the fungus to high concentrations of cadmium ions8.
  4. The production of exopolysaccharide (EPS) by D. quercina was investigated9.
