In the present study, the diversity, edibility, indigenous knowledge and distribution of wild edible mushrooms in the Northwestern Himalaya are discussed. The information provided herein was derived from a study carried out in the states of Uttarakhand and Himachal Pradesh during the period of 2000-2013. A total of 23 species of mushrooms considered as edible or used for trade were recorded. Twenty-one of these are basidiomycetes and two are ascomycetes. Certain species of Amanita, Agaricus, Astraeus, Hericium, Macrolepiota, Morchella, Pleurotus and Termitomyces are very commonly collected and consumed by the local people, whereas species of Auricularia, Cantharellus, Sparassis, Lactarius, Ramaria and Russula are less commonly collected and consumed. Cordyceps sinensis and several species of Morchella are collected specifically for trade purposes in the spring season in high elevation areas of the Himalaya. Among the edible wild mushrooms collected are a number of species involved in ectomycorrhizal symbiotic relationships with banj (oak), other broadleaf trees and several types of conifers. The results of the present study can be used to promote the domestication of those wild edible mushrooms not yet cultivated in India. These results also indicate the need to avoid over exploitation of these mushrooms and a reason to establish a 'state germplasm bank' to allow studies of tissue culture. The latter could serve as the basis of further scientific study into various ways of enhancing the livelihood of particular areas of northern India through increased mushroom domestication as well as assessing the possible bioactivity of mushrooms against certain human diseases.

Mushroom is a form of fungus having distinct fruit body produced either above ground or below ground. It can be easily noticed in moist habitat in and around forest, grassland, on tree trunks due to their peculiar appearance. Present communication discusses important habit and habitats, medicinal and culinary uses, status of mushrooms in Ethiopia, and sustainable use for sustenance and food security.

The present paper provides a distributional list of representative species of the Boletoid mushrooms in the Uttarakhand Himalaya. A literature survey revealed twenty-five taxa from the state, among these six, belong to the genus Suillus, four to Leccinum, three each to Boletus and Tylopilus, two each to Phylloporus, Pulveroboletus, Strobilomyces, and one each to Austroboletus and Xerocomus. Field photographs for some taxa are also provided herein for a better understanding of Boletoid mushrooms appearance and ecology.
