IDENTIFICATION AND ANALYSIS A NUMBER OF CHEMICAL COMPOSITIONS OF MYCORRHIZAL FUNGUS IN DALAT PINE FOREST

Abstract

     The results of analysis on the mycorrhizal for a number of chemical compositions showed that this is a high nutrient value species and it needs to be developed. This species of mushroom which are orange fruiting bodies with pale yellow flesh grow in clumps on the forest land in Da Lat. This mycorrhizal cap has flared and wavy edge, and its lobes curl inward. The mushroom has 3-5 cm cap and 4-9 cm in height. The dark yellow upper surface of the cap is smooth, fuzzless, and scaleless. The hymenium has gill-like ridges that run down its stipes and ramify in an irregular way. The major ridges are almost parallel at a fairly even intervals which have minor connecting ridges. The smooth and solid stipes which taper down from the cap are 1.0 - 3.0 cm across. The basidiospores contains 4-8 pale yellow spores. Basidiospores are ovoid shape with one slightly pointed end, size 4-6.5 × 7-10 micrometers. No cystidia. Monomitic mycelium, branching, locked in the septum, the thin fibers. In comparison with the key of Corner (1996), this mushroom species is Cantharellus cibarius, genus Cantharellus, family Cantharellaceae. These research results will help appraise the safety and nutrient values of the mushroom species which is being used for food by local people. The results also contribute to the findings and development of valuable resources of local area.
