Ischnoderma resinosum (Schrad.) P. Karst. Late fall polypore, resinous polypore
This polypore mushroom is a North American native, found throughout much of the continent. Identification: These fungi emerge from dead hardwoods or conifers, looking like gnarled, mummified ears. The "ears" (caps) are 1¾-12" (5-30 cm) wide and ⅜-1" (1-3 cm) thick. They sometimes emit droplets of water, which ball up on top of the resinous surface like beads of mercury. A tan to reddish brown resin often encrusts these fungi, whose interiors are white. There is no stalk. Edibility: Said to be edible when young and wet with exuded water, but these become corklike as they age.[1] Medical: These mushrooms contain compounds that are being investigated for possible use in inhibiting tumor growth in cancers.
