“…Singer, as well as species of Clitocybe. It therefore appears that neither of the choice edible species, L. nuda or L. sordida, are phylogenetically closely related to the core group of Lepista (Alvarado et al 2015;Vizzini et al 2012). Rather they fall into one of several clades comprising a large heterogeneous and complex group of collybioid fungi called "Clade III Collybia and allies" which contains Clitocybe, Collybia, and Lepista spp.…”

Lepista sordida is an edible and medicinal mushroom, but until now it had to be collected from the wild. The present study is the first report of the successful cultivation of a wild strain of L. sordida from Thailand. The morphological description and molecular examination of the fungus are included, in order to confirm the identification of the species. Optimization was carried out for mycelium growth and fruiting body production. The optimal conditions for growing the mycelia on solid medium were yeast malt extract agar (YMA), pH 6.3 and a temperature of 25 °C. A sorghum mushroom spawn was used for upscaling of the mycelium to be used for fruiting body production. Optimal conditions for the fruiting phase were 25 °C with 95-97% humidity in a compost rice straw medium with sandy-soil casing layer. Additionally, the secondary metabolites of fruiting body and cultured mycelium were investigated. Nudic acid B, a known toxic polyacetylene, was isolated from submerged cultures of L. sordida, while no polyacetylenic compounds were found in the fruiting bodies.

“…It is known to form fairy rings [ 7 ]. Paralepista species were generally assigned either to the genus Lepista or Clitocybe , until 2012 when Alfredo Vizzini and Enrico Ercole published a paper that confirmed by molecular analysis that these mushrooms are a separate clade from other Lepista species (such as Lepista nuda ) and also from Clitocybe species (such as Clitocybe fragrans ) [ 8 ]. This genus is recognized by Species Fungorum [ 9 ], and the Global Biodiversity Information Facility [ 10 ].…”

Antioxidant Properties, Bioactive Compounds Contents, and Chemical Characterization of Two Wild Edible Mushroom Species from Morocco: Paralepista flaccida (Sowerby) Vizzini and Lepista nuda (Bull.) Cooke

Mushrooms have been consumed for centuries and have recently gained more popularity as an important source of nutritional and pharmaceutical compounds. As part of the valorization of mushroom species in northern Morocco, the current study aimed to investigate the chemical compositions and antioxidant properties of two wild edible mushrooms, Paralepista flaccida and Lepista nuda. Herein, the bioactive compounds were determined using spectrophotometer methods, and results showed that the value of total phenolic content (TPC) was found to be higher in P. flaccida (32.86 ± 0.52 mg) than in L. nuda (25.52 ± 0.56 mg of gallic acid equivalents (GAEs)/mg of dry methanolic extract (dme)). On the other hand, the value of total flavonoid content (TFC) was greater in L. nuda than in P. flaccida, with values of 19.02 ± 0.80 and 10.34 ± 0.60 mg of (+)-catechin equivalents (CEs)/g dme, respectively. Moreover, the ascorbic acid, tannin, and carotenoids content was moderate, with a non-significant difference between the two samples. High-performance liquid chromatography–mass spectrometry (HPLC-MS) analysis allowed the identification and quantification of thirteen individual phenolic compounds in both P. flaccida and L. nuda, whereas p-Hydroxybenzoic acid was recognized as the major compound detected, with values of 138.50 ± 1.58 and 587.90 ± 4.89 µg/g of dry weight (dw), respectively. The gas chromatography–mass spectrometry (GC-MS) analysis of methanolic extracts of P. flaccida and L. nuda revealed the presence of sixty-one and sixty-six biomolecules, respectively. These biomolecules can mainly be divided into four main groups, namely sugars, amino acids, fatty acids, and organic acids. Moreover, glycerol (12.42%) and mannitol (10.39%) were observed to be the main chemical compositions of P. flaccida, while L. nuda was predominated by linolelaidic acid (21.13%) and leucine (9.05%). L. nuda showed a strong antioxidant property, evaluated by DPPH (half maximal effective concentration (EC50) 1.18–0.98 mg/mL); β-carotene bleaching (EC50 0.22–0.39 mg/mL); and reducing power methods (EC50 0.63–0.48 mg/mL), respectively. These findings suggested that both mushrooms are potential sources of various biomolecules, many of which possess important biological activities which are interesting for the foods and pharmaceuticals industry.
