to proceed to the identification of your mushrooms there are different ways and depend on the working conditions you have at your disposal, so I would suggest that you first try to purify your strains, so that you have pure cultures and have no error in the determinations , then you can look for the morphological characteristics of your strain, its structure, its text if it has color, the ability to grow in different crops and of course you should observe it to the stereum and to the microscope to see its conidia to which gender they belong. of course if you are able to use some molecular identification technique it will be great, in these case you can use ITS, Calmodulin or B tubulin as markers of regions highly conserved in fungi.
