Mycological Research 94 (3): 327-337 (1990). Basidiorne development of Volvariella bomb~cinawas examined with optical and scanning electron microscopy. Primary gills arose as ridges on the lower surface of the cap, projecting into a preformed annular cavity. Secondary and tertiary gills were added whenever space became available by bifurcation of an existing gill either horn one side or at the free edge, or by folding of the palisade layer near or at the roots of existing gills. These processes gave rise to sinuous, labyrinthiform hymenophores as a normal transitional stage to the mature regularly radial gill pattern. Although many cystidia spanned the gill space at the early stages, their tips causing depressions in the opposing hymenium, cryo-SEM examination showed that marginal and facial cystidia of mature gills bore droplets, suggesting that these cells are more likely to act as secretory elements than as structural members. Transformation of the convoluted gills into regularly radial ones is probably accomplished by cell inflation in the gill trama. Marking experiments and consideration of cystidial distribution suggest that V. bombycina gills grow at their root, not at their margin. Key words: Hymenophore development, Morphogenesis, Gill pattern, Cystidium, Volvariella bombycina. Volvariella bombycina (Schaeff. : Fr.) Sing., the silver-silk straw from expression of a series of essentially self-contained mushroom, is an edible fungus which fruits readily in culture.

Accepted 2 January, 2014 Mushrooms are the higher fungi which have long been used for food and medicinal purposes. They have rich nutritional value with high protein content (up to 44.93%), vitamins, minerals, fibers, trace elements and low calories and lack cholesterol. There are 14,000 known species of mushrooms of which 2,000 are safe for human consumption and about 650 of these possess medicinal properties. Among the total known mushrooms, approximately 850 species are recorded from India. Many of them have been used in food and folk medicine for thousands of years. Mushrooms are also sources of bioactive substances including antibacterial, antifungal, antiviral, antioxidant, antiinflammatory, anticancer, antitumour, anti-HIV and antidiabetic activities. Nutriceuticals and medicinal mushrooms have been used in human health development in India as food, medicine, minerals among others. The present review aims to update the current status of mushrooms diversity in India with their nutritional and medicinal potential as well as ethnomedicinal uses for different future prospects in pharmaceutical application. Key words: Mushroom diversity, nutritional value, therapeutic potential, bioactive compound. INTRODUCTION Mushroom is a general term used mainly for the fruiting unexamined mushrooms will be only 5%, implies that body of macrofungi (Ascomycota and Basidiomycota) there are 7,000 yet undiscovered species, which if and represents only a short reproductive stage in their life discovered will be provided with the possible benefit to cycle (Das, 2010).

Mushrooms are fungi which are cherished for their flavor as well for their nutritional value. They are low in salt and sugar and are a rich natural source of Vitamin D. Mushroom farming is gaining popularity day by day among new entrepreneurs. They are cultivated with specifically propagated spawns on a well prepared compost. Being tender in nature they deteriorate rapidly if not refrigerated or processed in time hence subjected to various processing methods such as drying, freezing, canning, pickling and sterilization. These methods not only preserves them but also helps in flavor development as in the case of pickling. Keywords: Mushroom, Moisture, Humidity, Temperature, Growth.

Molecular data supporting all examined collections as V. dunensis expand its known geographic distribution. A revised morphological characterization and a phylogenetic analysis of all Volvariella species sequenced to date are provided. Key words — Agaricomycetes, ITS, phylogeny, Volvariella volvacea Introduction The genus Volvariella Speg., which is composed of saprotrophic or mycotrophic agarics, has been historically considered a member of the family Pluteaceae Kotl. & Pouzar (Singer 1986). The genus is characterized macroscopically by a pink spore-print, free lamellae, and a universal veil that forms a saccate volva at the base of the stipe and microscopically by the inverse hymenophoral trama (Singer 1986). Results from earlier molecular studies (Moncalvo et al. 2002, Matheny et al. 2006) led to questions about its monophyly and phylogenetic position in the Pluteaceae.

  • 2 the Numbers Behind Mushroom Biodiversity
    15 2 The Numbers Behind Mushroom Biodiversity Anabela Martins Polytechnic Institute of Bragança, School of Agriculture (IPB-ESA), Portugal 2.1 ­Origin and Diversity of Fungi Fungi are difficult to preserve and fossilize and due to the poor preservation of most fungal structures, it has been difficult to interpret the fossil record of fungi. Hyphae, the vegetative bodies of fungi, bear few distinctive morphological characteristicss, and organisms as diverse as cyanobacteria, eukaryotic algal groups, and oomycetes can easily be mistaken for them (Taylor & Taylor 1993). Fossils provide minimum ages for divergences and genetic lineages can be much older than even the oldest fossil representative found. According to Berbee and Taylor (2010), molecular clocks (conversion of molecular changes into geological time) calibrated by fossils are the only available tools to estimate timing of evolutionary events in fossil‐poor groups, such as fungi. The arbuscular mycorrhizal symbiotic fungi from the division Glomeromycota, gen- erally accepted as the phylogenetic sister clade to the Ascomycota and Basidiomycota, have left the most ancient fossils in the Rhynie Chert of Aberdeenshire in the north of Scotland (400 million years old). The Glomeromycota and several other fungi have been found associated with the preserved tissues of early vascular plants (Taylor et al. 2004a). Fossil spores from these shallow marine sediments from the Ordovician that closely resemble Glomeromycota spores and finely branched hyphae arbuscules within plant cells were clearly preserved in cells of stems of a 400 Ma primitive land plant, Aglaophyton, from Rhynie chert 455–460 Ma in age (Redecker et al. 2000; Remy et al. 1994) and from roots from the Triassic (250–199 Ma) (Berbee & Taylor 2010; Stubblefield et al.
