Ischnoderma resinosum – Resinous Polypore

The resinous polypore is thick and fleshy when young with a pale brown cap and thick white margins. The mushroom toughens and the cap becomes a darker brown with age. The cap surface can emit droplets of water which ball up like beads. The white pore surface bruises brown when handled.

The mushroom is edible when young and tender. As the mushroom ages, it gets corky. Young tender edges are best cooked slow in a stew due to their high-water content. Older mushrooms can be used to make mushroom stock.
