In humans, a wide range of health disorders have been induced due to an imbalanced metabolism and an excess generation of reactive oxygen species (ROS). Different biological properties found in mushrooms seem to be the reason for their customary use as a favourite delicacy. Therefore, exploration of wild edible mushrooms as a source of various biological compounds is gaining much importance today. <i>Amanita konajensis</i>, one of the underutilized macrofungi popularly consumed in Eastern India, demands a systematic study of its medicinal values. The study aims to explore the myco-chemical contents of <i>A. konajensis</i> ethanolic extract (EtAK1) and screen their antioxidant potency through various <i>in vitro </i>assays. GC-MS analysis identified the chemical components of EtAK1. Further, structure-based virtual screening of the identified compounds was analysed for drug-like properties and molecular docking with the human p38 MAPK protein, a potent targeting pathway for human lung cancer. The morpho-molecular features proved the authenticity of the collected mushroom. The screening assays showed that EtAK1 was abundant in flavonoids, followed by phenolics, &beta;-carotene, and lycopene, and had strong antioxidant activity with EC<sub>50</sub> values of 640-710 &mu;g/mL. The GC-MS analyses of EtAK1 identified the occurrence of 19 bioactive compounds in the mushroom. <i>In silico</i> analysis revealed that anthraergostatetraenol p-chlorobenzoate, one of the compounds identified, displayed high binding affinity (&#916;G &#61; -10.6 kcal/mol) with human p38 MAPK. The outcome of this study will pave the way for the invention of myco-medicine using <i>A. konajensis</i>, which may lead to a novel drug for human lung cancer.

The cosmopolitan fungal genus Ganoderma is an important pathogen on arboreal plant hosts, particularly in tropical and temperate regions. It has long been used as a traditional medicine because of its medicinal properties and chemical constituents. In this study, Ganoderma collections were made in the Greater Mekong Subregion (GMS), encompassing tropical parts of Laos, Myanmar, Thailand, Vietnam, and temperate areas in Yunnan Province, China. The specimens used in this study are described based on micro-macro-characteristics and phylogenetic analysis of combined ITS, LSU, TEF1α, and RPB2 sequence data. In this comprehensive study, we report 22 Ganoderma species from the GMS, namely, G. adspersum, G. applanatum, G. australe, G. calidophilum, G. ellipsoideum, G. flexipes, G. gibbosum, G. heohnelianum, G. hochiminhense, G. leucocontextum, G. lucidum, G. multiplicatum, G. multipileum, G. myanmarense, G. orbiforme, G. philippii, G. resinaceum, G. sichuanense, G. sinense, G. subresinosum, G. williamsianum, and G. tsugae. Some of these species were reported in more than one country within the GMS. Of these 22 species, 12 were collected from Yunnan Province, China; three were collected from Laos; three species, two new records, and one new species were collected from Myanmar; 15 species and four new records were collected from Thailand, and one new species was collected from Vietnam. Comprehensive descriptions, color photographs of macro- and micro-characteristics, the distribution of Ganoderma within the GMS, as well as a phylogenetic tree showing the placement of all reported Ganoderma from the GMS are provided.

AbstractWild mushrooms are a vital source of income and nutrition for many poor communities and of value to recreational foragers. Literature relating to the edibility of mushroom species continues to expand, driven by an increasing demand for wild mushrooms, a wider interest in foraging, and the study of traditional foods. Although numerous case reports have been published on edible mushrooms, doubt and confusion persist regarding which species are safe and suitable to consume. Case reports often differ, and the evidence supporting the stated properties of mushrooms can be incomplete or ambiguous. The need for greater clarity on edible species is further underlined by increases in mushroom‐related poisonings. We propose a system for categorizing mushroom species and assigning a final edibility status. Using this system, we reviewed 2,786 mushroom species from 99 countries, accessing 9,783 case reports, from over 1,100 sources. We identified 2,189 edible species, of which 2,006 can be consumed safely, and a further 183 species which required some form of pretreatment prior to safe consumption or were associated with allergic reactions by some. We identified 471 species of uncertain edibility because of missing or incomplete evidence of consumption, and 76 unconfirmed species because of unresolved, differing opinions on edibility and toxicity. This is the most comprehensive list of edible mushrooms available to date, demonstrating the huge number of mushrooms species consumed. Our review highlights the need for further information on uncertain and clash species, and the need to present evidence in a clear, unambiguous, and consistent manner.
