I have no specific knowledge of this specific species concentrating heavy metals, pesticides, or any other type of soil contaminant. I just know that some fungi do do so, and so it may be unsafe to eat anything found growing on contaminated land.
to me. And this is the first time I have heard of G. frondosus being able to concentrate heavy metals, Paul. Do you have a citation? Just to be on the safe side, try doing a search of Grifola frondosa and heavy metals.
This is a good Edible. The Japaneses refer to it as the dancing mushroom because when they find it they do a little dance. Along with being a very safe edible also Reported to have good medicinal benefits and cancer fighting polysaccharides
but there are some lookalikes as Dendropolyporus umbellatus with hats on stipes,
Bondarzewia berkeleyi even bigger and Meripilus giganteus which is blackening on pressure or cutting. I am not sure if the last one is edible but the others should be all safe to eat. In Europe these species are so seldom seen that it is not considered to eat them.
and it’s fresh and growing on untainted ground, yes. If there’s heavy metal contamination of the soil, pesticide application, etc. in an area where a particular mushroom grew, that one cannot be considered safe to eat however.
I found 2 of these by a large old white oak tree in my front yard,- can I eat it?
