Abstract :The species from the genus Ganoderma are known to be extremely important macrofungi in fundamental biological, medicinal, and socioeconomic aspects. The present communication describes the brief morphological description, macro- and microscopic details, and chemical constituents of the representatives of five species of Ganoderma mushroom collected from different sites in Vietnamese National Parks. These species were Ganoderma colossus, G. Neojaponicum, G. Cattienensis, G. Lucidum, and G. Applanatum. Three additional herbarium strains of Ganoderma from European and Siberian regions have been implemented in the present framework for the purposes of comparison. Cultural characterization on solid and liquid fermentation, and scanning electron microscopy of morphology along with chemical analysis served as the supporting identification and comparison factors. Low-molecular-weight chemical constituents were evaluated by gas chromatography-mass spectrometry and gas-liquid chromatography techniques. Valuable substances insert ignore into journalissuearticles values(2-monolinolein, 2,3-dihydroxypropyl elaidate, fatty alcohol, fatty acid alkyl esters, and free fatty acids); detected in pigmented mycelia and submerged cultures have promising biotechnological applications including in food supplements, lipid-based drug delivery systems, and biodiesel-related items. The representative voucher specimens were deposited at the Herbarium of the Southern Institute of Ecology insert ignore into journalissuearticles values(Ho Chi Minh City, Vietnam); and were assigned accession numbers.
