Lenzites betulina (L.) Fr.


The species is saprobic on the deadwood of hardwoods. Annual; growing singly or in overlapping groups on logs (hardwoods and coniferous woods); producing a white to straw-colored rot of the sapwood[1]. The specimen is collected from Maharashtra Nature Park, Mumbai.




Cap up to 25 cm in diameter; semi-circular with concentric zones, particularly near margin, irregularly bracket-shaped;  surface, yellowish whitish to grayish brown, flexible; sometimes developing greenish coloursat maturity as a result of algae. Hymenium with plate like gills, daedaleoid towards margin, whitish and tough. Context white, stem absent1.


Culinary value:


It is inedible as food[2].


Medicinal importance:


  1. 1.The research was carried out to study anticancer properties, antibiotic activity, and chemical composition of betulina. The strong anticancer activity against tumour cell line was exhibited. The antimicrobial activity was evaluated against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Fusarium graminearum, Gibberella zeae, and Cercosporella albo-maculans which are found to be moderate. Thus, L. betulina can be considered as a good anticancer and antibiotic agent[3].
  2. 2.Lenzites betulina showed antidiabetic property and can be used as an alternative medicine to widely used current medicines[4].


Industrial importance:


Lack of information


Unique features:


The gills are tough and leathery, unlike other true gilled mushrooms. The pores of this fungus develop into gill-like structures2. 


Interesting facts:


Lack of information


Commercial products:


Lack of information


Review of patents:


The invention where specific concentrations of extracts from pure cultured mycelium from Lenzites betulina and many other mushrooms are utilized.  The mushrooms are used to reduce the harmful viruses in bees and to increase the longevity of bees[5].


Review of publications:


  1. 1.The chemical components of betulina proved to have some antioxidant capacities, and could be used as a potential source of new natural antioxidants[6].
  2. 2.Two lipid peroxidation inhibitors, betulinans A (1) and B (2), were isolated from betulina and their structures were determined[7].
