Gelatinous and cartilaginous fungus when wet. When dry, they decrease in size and firm up. This is the “black” mushroom commonly used in Chinese, Vietnamese and Japanese cuisine: miso soup, noodles, etc. Its consumption in its raw state would present a slight toxicity, it is therefore advisable to cook it.
Little known in our Western cuisine, it is nevertheless indigenous to our regions and is typically found on the dead branches of the elderberry. Legend says that after his betrayal, Judah, filled with remorse, hanged himself from one of these trees...
Storage: +-1 month in the fridge
