Lepista sp.

 

Where to find:

 

Saprobic in nature, growing alone or with others in leaf litter or soil, also found in organic debris in urban areas. The specimen is collected from Manikgad, Alibag.

 

Species morphology:

 

Cap is up to 20 cm, convex with incurved margins when young; however, at maturity becomes almost flat with wavy margin. Surface is smooth, sticky when young. Purplish brown to brown in color. Gills are crowded, pale lavender to lilac, fading to buff, pinkish-buff or brownish. Stem 3-10 cm long, 1-3 cm thick and sometimes enlarged at the base, purple to brown in colour. The fruitbody is fragrant[1].

 

Culinary value:

 

  1. 1.Edible however, causes gastrointestinal upsets if consumed raw[2].
  2. 2.Mushrooms can be sautéed in butter and eaten. They can also be cooked like tripe or as omelette filling. A good mushroom stews can also be prepared. They have a strong flavour and hence can be combine with leeks or onions. They can also be preserved in olive oil or white vinegar after blanching[3].

 

Medicinal properties:

 

  1. 1.Extract of Clitocybe nuda(Lepista nuda) were studied for antihyperlipidemic and antihyperglycemic effects and results showed that the species has the therapeutic potential for the protection against diabetes and hyperlipidemia[4].
  2. 2.Vitamin B1 was found to be present in the sporophore of nuda. Infusion of this macrofungus was used for preventing beriberi and decoction was used for the treatment of abscesses and wounds. A couple of bacteria and fungi found to be sensitive to methanolic extracts of L. nuda and hence can be used as a supportive to ethnomedicine[5].

 

Industrial importance:

 

  1. 1.Blewits yield a grass green colour when cooked in an iron pot and thus can be used for dyeing textiles and paper[6].
  2. 2.The ethanolic extracts can be used as antimicrobial and antioxidative agents in the food industry[7].

Publications:

 

  1. 1.Chemical composition and antioxidant potential of Lepista nuda samples from different habitats, and mycelia produced by in vitro culture using different culture media were compared. Among them fruiting bodies of commercial sample gave the highest levels of energy, PUFA and phenolic compounds; the wild sample from oak forest gave the highest levels of organic acids. Mycelia samples showed higher levels of glucose, tocopherols and antioxidant activity[9].
  2. 2.Effects of water extracts of Clitocybe nuda (Lepista nuda) on murine bone marrow derived dendritic cells were studied and proved that water extracts can be used as an adjuvant in cancer vaccine immunotherapy[10].
  3. 3.Intraspecific morphological and genetic differences in nuda were identified using combination of restriction-site associated DNA” (RAD) method and high throughput sequencing[11].
