Mycena (Pers.) Roussel

The species of Mycena are saprotrophic and extremely small mushrooms. Majority of species are grey, brown and white in color, while a few are brightly colored[1],[2].

The specimen was collected from Amboli.

Morphology:

Pileus up to 40 mm diam., convex, mammillate umbonate; surface uniformly reddish brown, smooth, translucent striate; margin entire. Gills adnexed, white, moderately spaced with lamellulae of different lengths. Stipe up to 35 × 3 mm, tubular; surface white, translucent, smooth, arising from a basal bulb.

Culinary value:

Some species of Mycena are edible, however for most of the species edibility is not known as they are too small for cooking. Some species contain toxins2.

Medicinal importance:

Mycena fruiting body extracts exhibit 60% inhibition against sarcoma 180 and 70% against Ehrlich carcinoma, while slippery Mycena exhibit 90 and 100% inhibition against sarcoma 180 and Ehrlich carcinoma, respectively. Leaianafulvene, a pigment isolated from orange Mycena proposed to have anticancer properties which are under investigation[3].

Interesting facts:

  1. Mycena haematopus, exude a latex when the stem is broken2.
  2. Many other species of Mycena have a chlorine-like odor2.
  3. Around 33 species of Mycena known to have bioluminescent properties2.

Review of patents:

The microbial inoculant was invented from M. dendrobii F48 compound and their applications were explained. It was prepared from 3.5 parts of M. dendrobii F48 pure culture, 6.5 parts of Trichoderma pure culture, and an adhering agent accounting for 2 percent of the total weight of the Trichoderma pure culture and the M.dendrobii F48 pure culture. The inoculant was supposed to speed up the growth of a dendrobe seedling, increasing the contents of bioactivator polysaccharide and dendrobine and meeting the requirements of developing compound sustainable agriculture, ecological agriculture and green agriculture, and was mentioned to be suitable for large-scale production of the dendrobe as a rare medicinal plant[4]. The inventors were Wang Huizhong et. al. and the applicant was Hangzhou Normal University. The patent was granted by European Patent office.

Review of publications:

  1. Mycena holoporphyra was first recorded from Argentina. The species was illustrated and described along with the differences with its closest taxa. A key to the species of Mycena Calodontes subsect. Purae from Argentina was also provided[5].
  2. The study reported Mycena margarita, a frequently bioluminescent species for the first time from Brazil. The species was found to be distributed on decaying wood in the Araripe National Forest, municipality of Crato, Ceará state. The study has described and illustrated margarita along with color photographs of fresh basidiomata along with the taxonomy and ecology of the species[6].
  3. A new section, sect. Spinosae, was proposed to accommodate Mycena species that have both thin-walled pileocystidia and diverticulate hyphae on the pileipellis. Two new species, mridula and M. rasada, were proposed in the new section and five other species of Mycena, currently assigned to other sections, were included in this new section. A key was also provided for all species included in the proposed section[7].
  4. Two new Mycena species, viz. asterina and M. lucentipes were described as bioluminescent and illustrated from a single site in primary Atlantic Forest habitat in the Parque Estadual Turistico do Alto Ribeira, Sao Paulo State, Brazil. For already described Mycena fera, M. singeri and M. discobasis luminescence was reported for the first time. A phenomenon of bioluminescent species of Mycena was also described[8].
  5. Mycena lacrimans was re-described from the type locality and reported for the first time as bioluminescent. A comprehensive description, illustrations, photographs, comparison with phenetically similar species, and discussion of phylogenetic relationships were provided[9].
