Auricularia americana

A jelly ear fungus that decays dead conifer wood across North America, mainly in the Northeast, with further records from China and the Russian Far East. It is the only North American Auricularia on conifers, which separates it from the broadleaf A. angiospermarum. Dedicated cultivation methods are not published, so the growing notes adapt standard wood ear practice.
