Boletus colossus is an Ectomycorrhiza fungi. It grows on roots of big trees such as Rubber tree, Mango tree and etc. This mushroom grows by using the organic materials released from the roots. The moisture adsorbed on the fungi makes the roots resist the drought better. The mushroom can also turn some insoluble inorganic materials into the form that plants can make use of. This research is to study the production of the starter culture by using low-cost media. The result shows that the fungi can grow best in whey to 9.2 g/L (dry weight) in 10 days. The liquid broth can inhibit the growth of pathogens ( Alternaría brasicola, Alternaría pori, and Fusarium solani ) on Potato-Dextrose agar. The starter culture can also be produced in a 50L fermenter to the dry weight of 8.1 g/L in 6 days. Loam is the best as solid carrier followed by peat moss. The result in one year shows that the Para rubber trees grow with the fungi that have significantly longer stems, leaves, and roots.
