Hello Molometer,
As I mentioned above, I strongly advise to never pick or eat any wild vegetable or fungus you are not intimately acquainted with. Great care is needed, tuition by a knowledgeable elder or trained guide is essential.
        But however one can identify mushrooms when no better authority is present by their spore prints - you will need to google how to do this but it is not hard. Essentially you dry the mushroom on a piece of paper and note the specific pattern of spore distribution which is like a fingerprint and equally unique.

Thank you for the resteem - Have fun in the forest :D
